Followed node installer. Console says npm is now installed but node is not. [HELP]

I downloaded and ran the v8.2.1 installer from the node site https://nodejs.org/en/ and went through the set up process, then restarted. Everything seemed to go fine. But when I type node -v in the terminal, it says it is not installed.Then I downloaded and ran the earlier version installer and the set up wizard said I had a later version installed. Again the terminal says it is not.But if I type npm -v it gives the file path where it is installed. I installed npm with node in the original installation. I am lost for what to do. Help please?

Nested eventEmitters

I have a class that manages a list of dependent items, and a class that represents the item itself. Both the item class and list class can emit events. Users don't generally need to directly manipulate the item objects as the dependency tree is the primary utility provided by the module. Is there a way to have a single event stream? I think I can do it with a singleton emitter, but I really like to stay away from singletons. Would also love to avoid re-emitting every event from the item class, (too easy to forget to add the re-emitter for a new event, also extra typing)Example of what I'd like to do. Line 45 in the example is how I'd like the consumer to interact with the events. Are singletons that ugly here? Is the re-emit pattern better than a singleton? Does it matter? ;)example: http://ift.tt/2vgwA8Z EventEmitter = require('events'); class Foo extends EventEmitter { constructor(){ super(); } fooEmit(){ this.emit('foo'); } } class Bar extends EventEmitter { constructor(foo){ super(); this.foo = foo; // Would like to not have to do this for each // event from foo this.foo.on('foo', () =>{ this.emit('re-emit foo'); }) } passthroughTest(){ this.foo.fooEmit(); } barEmit(){ this.emit('bar'); } } // Want users of Bar to get all the events from Foo bar = new Bar(new Foo()); // works (understand this, just like having a known case) bar.on('bar', ()=>{ console.log('bar emitted'); }) // passing through all of the events from Foo would be awesome bar.on('foo', () =>{ console.log('thisWorks'); }) bar.on('re-emit foo', () =>{ console.log('Would like to avoid this pattern'); }) bar.barEmit(); bar.passthroughTest();

How do I insert values only if they arent null or meet whatever condition I want with MongoDB + Express

For example, if "producerName" doesnt equal "Jimbo" or if "producerBGPhoto2" in null, how can I skip those from being inserted or if they dont meet the condition, they get a value of whatever I want. The only logical thing I can think of is, doing an if statement for each value, and then doing an insert for each, but there sounds like a better way.router.post('/producers/adding', auth, multipartyMiddleware, function(req, res) { var db = req.db; var producerName = req.body.name; var producerSlogan = req.body.slogan; var producerLocation = req.body.location; var producerOwner = req.body.owner; var producerWinemaker = req.body.winemaker; var producerWebsite = req.body.website; var producerCountry = req.body.country; var producerParentRegion = req.body.parentRegion; var producerSubregion = req.body.subregion; var producerBio = req.body.bio; var producerEstateAge = req.body.estate_age; var producerLatitude = req.body.latitude; var producerLongitude = req.body.longitude; var producerCoords = req.body.coords; var producerLogo = req.files['logo'].path.substring(6); var producerMap = req.files['map'].path.substring(6); var producerBGPhoto = req.files['bg_photo'].path.substring(6); var producerBGPhoto2 = req.files['bg_photo_2'].path.substring(6); var producerBGPhoto3 = req.files['bg_photo_3'].path.substring(6); var producerBGPhoto4 = req.files['bg_photo_4'].path.substring(6); var producerBGPhoto5 = req.files['bg_photo_5'].path.substring(6); var producerSlug = producerName.replace(/\s+/g, '-').toLowerCase(); var collection = db.collection('producers'); collection.insert({ "slug": producerSlug, "name": producerName, "slogan": producerSlogan, "location": producerLocation, "owner": producerOwner, "parent_region": producerParentRegion, "subregion": producerSubregion, "country": producerCountry, "winemaker": producerWinemaker, "website": producerWebsite, "bio": producerBio, "estate_age": producerEstateAge, "latitude": producerLatitude, "longitude": producerLongitude, "coords": producerCoords, "logo": producerLogo, "map": producerMap, "bg_photo": producerBGPhoto, "bg_photo_2": producerBGPhoto2, "bg_photo_3": producerBGPhoto3, "bg_photo_4": producerBGPhoto4, "bg_photo_5": producerBGPhoto5 }, function(err, doc) { if (err) { res.send("problem adding to db"); } else { res.redirect("../producerslist"); } }); });

Naming conventions in Express: middleware vs. controllers

I have a question about naming conventions in the NodeJS/Express ecosystem. I understand that middleware is just a function that takes a request/response object can manpiulate those objects, end or continue the response cycle, etc. I also understand that routing controllers are used to define route actions. I am confused when a method would be considered "middleware" vs when it would be considered a "controller". If we imagine a scenario where a user uploads a photo, then a server manipulates the photo (e.g. adds a watermark), uploads the photo to s3, and then saves a Photo model instance in our database, we might have something like the following:function manipulatePhoto(req, res, next) { next() } function uploadPhoto(req, res, next) { // upload photo to s3 next() } function createPhoto(req, res) { // create new photo using ORM then send response PhotoModel.create({}) .then(() => { res.status(201).send(photos); }); } router.post('/photos/', manipulatePhoto, uploadPhoto, createPhoto); In the example above, would each method be considered a middleware method? Would all the methods fall under the umbrella of a "PhotosController"?

The posts are then given to the jade templating engine that then renders an html page with posts.As it is now, I could handle everything with strictly node/express. My question is, where does a front-end framework fit in all of this? What are some things that front-end frameworks enable that I cannot do with node/express alone?

Best way to use Typescript with node & browsers

I've been working on a game as a hobby on and off for about a year now and it's finally come time to implement the multiplayer aspect of it.I've managed to get a simple Node server up and running and send messages between the server & clients.I'm using TypeScript on the client without issues, but issues arise when I put client & server code in the same project.On the clientside so far I've been using RequireJS with ES6 imports and it's been working great.. But this seems incompatible with Node's own Require function, and TypeScript complains. I've also tried Browserify & SystemJS without much luck.The client and server will essentially be separate apps, but will need to share common data - Enums, Interfaces, cfg, etc.Does anyone have any ideas, examples, or tutorials that would help me in this matter?Thanks for your time!

Can I implement token based auth in a «cookie-like» way?

I'm creating my first SPA using NodeJS stack for development and I came to a point where I should design authentication and secure some parts of the app.I read a lot about auth techniques including JWT, OAuth, etc. but I still didn't find something like «a real world example».Let's assume that my task is just to secure some parts of app from public. My app isn't designed to work with 3rd party services so I see no need to use something like Google or Facebook auth. I want to use login/password and store all this data using my own database server.I don't understand the point of having authentication stateless. I came to a simple conclusion that I can design authentication in this way:I store users logins and passwords in my database.User auth means that user enters his credentials, server checks it and creates token. Then server saves this token into database. User saves token using browser local storage or somewhere else if it's not browser environment.On each request client sends this token, server checks that this token exists and responds appropriately.User can login from different devices, we just create multiple tokens for him.We can end specific session or all sessions by just deleting user tokens from database.We can manage tokens in a way we want, for example server can check expiration time and invalidate (delete) token.Is it OK? JWT require additional implementation if we need to invalidate token, I saw different examples, all of them were based on storing invalid tokens but what's the point of that if we can just store valid tokens? We already lose statelessness by implementing this storage.I see that I can just use cookies instead of implementation described above but I don't like an idea to use cookies in RESTful app because I don't see the point of sending cookies from not-browser like environment.What are the disadvantages of just storing tokens on server this way?

How to Use Async/Await to Wait for forEach Loop to Complete Before Moving On

I've searched for solutions, but I'm not quite getting it. I want to process some calls thru a _.forEach() loop, and not continue until after the loop is complete... or, rather... until all the code called from within the loop is complete... but I'm not sure where to put the asyncs and awaits to accomplish this.For example: let sources = { ...a dictionary... } async function getAllData() { _.forEach( sources, function( source ) { processThisSource( source ) // I want all these processes to complete before moving on } } getAllData().then( () => {} ) This doesn't seem to work. Can someone point me in the right direction?Thank you!

Best practices for app with web and worker processes, and communicating background job results to client via socket.io?

I have a question about the best practice structure when dealing with a web server, background worker job queues, and needing to push job results to connected clients via websockets using socket.io.Normally I have the following setup: Web server receives request, responds to client quickly, then starts a new background job on a worker queue. On the worker side of things some work is done and saved to the database, maybe an email is sent out, etc. However, for the first time I now need to communicate the job results back to the client using socket.io.So my question is how to properly push job results to the client? Should the worker be able to use something like socket.io to communicate back to the client? Is this even possible if the client is connected via socket.io to the web server, but the background worker is on a completely different machine? I guess an alternative would be the worker could queue up a "results" job itself that the web server listens for, and then the web server would be the one sending the socket.io message back to the client, but I'm just not sure how practical this is or what the best way to do this is.I don't have a ton of experience with websockets or scaling large apps so curious how to structure all of this. Appreciate the help thanks!

Heroku and multiple apps?

Hi there!So it's my first steps in the world of nodejs and I'm ready to host my app.I read that Heroku was pretty good, so I looked into it.So it seems to be 1 dyno per app? It get expensive fast for my small project.What I need to host : - Angular Landing page - Angular Transaction web app - A little ETL app made with nodejs. (extract data from a zip file taken in a ftp and upload it to nosql database)Can I do all of this on the same Dyno? There won't be much traffic early (and probably ever).I could probably make one app with the landing page and the transaction web app, and the ETL won't require web input.Should I use multiple hobby dyno? Or go with 1 hobby dyno and host it all on the same.I'm asking this question there cause I don't know what kind of ressources require Nodejs.Also if you have anything else then Heroku that you use, I'm open!

Hi,I've been tinkering with webdev for at least a year now in my free time. My frontend skills are pretty decent and I have a ubuntu server hosted by DigitalOcean running a LAMP stack.I want to move away from LAMP (as I'm not a fan of php, and want to learn the new hip tech) and move towards Node! I tried Django but settled for the JS option, i'm also terrible with apache..I've started learning Node with express but I'm getting myself a little confused with how to implement all of my domains, pages & apps on one server. After lots of googling, I came to a shaky conclusion...Am I right in thinking:I think I need to run apache/nginx anyway, and I can run nginx on the server, which routes the requested url to different node apps? i.e www.mysite.com goes to one particular app, www.othersite.com goes to a different app.Do I use a separate node app for each page? i.e do www.mysite.com and www.mysite.com/about use different node apps?Do I even use node for static pages?I'd really appreciate some clarification! I feel totally swamped here.

Hi,I have code that updates data in a database (I'm using Sequelize as ORM) and passes the status of update request to the client (I have vuejs on the front end). The code works for my purposes but I would like to know if there are 'better' ways to handle error cases.my code below:app.patch('/api/device/updateshipment', function(req, res) { Device.update({ so_number: req.body.so_number, shipment_date: req.body.shipment_date }, { where: { serial_number: req.body.serial_number } }) .then(function(updatedDevices) { if(updatedDevices[0]) { res.status(200).end('Shipment details updated'); } else { res.status(404).end('Serial Number not found'); } }) .catch(function(err) { console.log(err) }) In the front end, the update status message (e.g. 'Shipment details updated') is then displayed to the user.How would I make use of the Error object in the case above (and is using Error object in this case considered best practice? Why?). Any other recommendations welcome!Thanks in advance!!

Best Practices for representing Times in Node

(I'm still getting my head around some things here, so sorry for the simple questions.) What is the best recommended way internal to your application to pass dates and times around?Currently I'm loading from the data store, converting into a Moment object in the UTC Timezone inside the DAO, and passing this Moment object around. And this works fine, but it's a bit clunky at the unit testing layer - I can't trivially just compare two objects that happen to contain a Moment and expect it to work.Is it better to instead pass around a Date() object - given that Javascript doesn't do timezones properly? Or to pass around a unix timestamp (seconds or millis since the epoch) or an ISO-8601 String? All of these would work better for unit tests, and then I can do the conversions for timezones and formatting at the very last moment. I'm currently leaning towards the ISO-8601 string, but I'm not sure what is the generally recommended best way to handle this?For reference - I'm talking about what data type to store these values in inside the model objects that are used in between the DAO and the HTTP layer, and these model objects travel in both directions. Inside the database it's just a TIMESTAMPTZ that is used, always in UTC, and over the HTTP API it's always an ISO-8601 String, but on occasion in between the two I need to be able to compare and manipulate the values.

Question about promise and callback

Hi, I've recently discover all the power of the promises. But like many newbie I fall in the trap of using this paradigme most of the time (even when I don't need it). So basically most of my route are like that : /my-routeparams = {all object from the req I formatted in the first function}myFunction1(params)then(myFunction2)then(myFunction3)then(myFunction4)then(myFunction5)then(function(params){send result})catch(send error) Note: Param is an object where every function modify/add property to it. Until the final result. In one side, it's really really clear. I can move/remove/comment functions in 1 second. And catch the error quite easily. But I don't at what extend it's slower. But it is definitively slower than callback. I have to add to that (yes, i'm really trapped!) that most the function in the process called themselves other promises. It's a bit complicated, but put simply I have to generate data and file and then return a urls of those file. So there are Q.all() here and there. So my questions : 1) Is there a design pattern to have the power of promise but without falling in this trap 2) Is it a good practice to use promise on long process (but non async) ? I know there are some function that can take 50-100ms because of cpu calculation. 3) Any advice for me Thank you so much for your feedback. (my code really need it!)

Is es6 completely useless?

Hi guys,I would like your opinion about a conversation I had with my client. I developed an API in Node.js using Express + Postgres database for Heroku, It's a simple app to allow users to write internal support tickets, nothing fancy.The client's javascript specialist gave me the following feedback:"Never use es6 classes or extends, only objects (even though I know it's syntactic sugar); never try to write a db layer, use ORMs for that."To put the icing on the cake, the client also said I'm probably the only person who uses extend in javascript.Do you guys agree with the above statements? Why not to use es6 classes if they exist?Unfortunately I can't post the code here for obvious reasons.

Could Use Some Guidance Regarding HTTP-Request/WebSocket Scenario

Hi all,My goal is straightforward. I have a script ABC that produces the result XYZ only when entered in the console of website 123. AFAIK this website does not have specific code in it that allows others to connect and retrieve data (so socket.io is out of the question).I've tried a Websocket connection, but it keeps on failing (according to http://ift.tt/1u59RQK, the website isn't even allowing the connection, so not a fault in my code). Currently messing around with HTTP-Request. Is there some sort of library or npm module I could install that would help me out here?Basically, what's the best way to code my node.js file to send script ABC to website 123, and then retrieve the result XYZ and log it in my client-side console?Thanks in advance for any tips.

Some questions about NodeJS

I have nodeJS/NPM installed globally (on my native machine) - I am installing packages locally in a project which get put into node_modules folder - and then as I install them - they get added to my package.json dependancie file in the root of my project directory.So #1 - I just installed one package, and my node_modules folder in my project folder is 11 mb in size. If I am going to deploy this to a customer, how does this even work? Where are all of these files being stored/served? Is this the whole purpose of nodeJS? That they would be stored server-side and the client would just access the actual files as needed without requiring the download of them? I think that's kind of an eye opener for me if that's the case2 - If I wanted to have a project with an admin panel - so basically a way for the owner of the project to be able to change the layout of a project for example in real-time. Would I be able to do this strictly with nodeJS without a database - or would I still need something like MongoDB or just a regular database to store the properties of the project?Thanks sorry for the dumb questions

Question about multiple async http calls

i'm fairly new to node and trying to push a bunch of documents up to AWS CloudSearch. I have 17 batches to send and I'm concerned about firing off 17 async http post calls at the same time. Does node manage things to not bog down the server, or do I need to manually build a queue to limit the number of calls going at one time?Likewise for downloading, I have to download over 400 files via GET. I built a queue using an EventEmitter to run them serially because I was worried about saturating the net connection and hitting the source server with a ton of requests at the same time but I'm guessing there's a better way.I'm using Node 8 and using async/await where I can.

GroupMe Bot that Responds to a Specific User

I've been tweaking a copy of the GroupMe Node JS sample bot provided here, and I'm trying to create a simple bot that responds to one particular user in my group chat every time he says a certain word. I was able to tweak it to respond to the word, but I have not found a way to only have it respond to a certain user. The relevant code is located in the file "bot.js." The section "function respond()" contains the default trigger text for the reply (This is the original code, my only modification was replacing "/cool guy" with the new word)function respond() { var request = JSON.parse(this.req.chunks[0]), botRegex = /^\/cool guy$/; if(request.text && botRegex.test(request.text)) { this.res.writeHead(200); postMessage(); this.res.end(); } else { console.log("don't care"); this.res.writeHead(200); this.res.end(); } } Is there a line I can add to "function respond()" to check for the username as well as the text?

Confused on where to go with learning Node

My introduction to node was Colt's Web Developer Bootcamp course. After doing that and feeling relatively confident, I decided to continue with Learn Node course by Wes Bos. After only a few videos I realized that the way Node was written in those two courses was very different (I'm guessing that's because Colt's course is older). I also dislike the fact that Wes' course includes so many files that he wrote before the course, making me feel kinda lost and not very competent. I'm about 15 videos in and I feel like if I started writing a new website myself, I wouldn't be able to transfer those skills because I don't have the same helper files that he wrote.After that I decided to check some other resources for learning Node. Most of them were older so I'm worried that they'll be outdated just like Colt's course (which I'm not even sure if it's outdated because my only Node experiences are those two courses).What are your opinions on this? Where do I go from here? Thanks for reading.

Why won't node show syntax error location?

I thought they would have fixed this by now, but when I require a JS file that happens to have a syntax error in it, node, and specifically the vm.js file says that the line where I require it has the syntax error. That is totally unhelpful to the developer. Is there a work around to show the exact line the syntax error is on in the file? I've tried process.on('exit', function(e) { throw e }); but it seems that that function is never even called. Why wouldn't they add this by now?

Newbie Code Review

Hey guys, I'm a newbie to node/js and my first (and most fun ) project is making a discord bot with node. It's gone decent and the bot doesn't seem to have nearly as many issues as it used to, but I can't figure out how to make it better, yet.I'm gonna post a few command files here that I feel like aren't that great, can you review them for me and explain what I could do better? Be warned, it's a bot based around shitposts and memes.Command Name: AnnoyUse: Annoys a target user, or yourself if you forget to target someone.Potential Problems? This code feels repetitive and ugly, and I'm not sure how to make it better.Code: http://ift.tt/2uJd8BA Name: TweetUse: User can send a tweet from the memebot's accountPotential Problems? The command feels slow and buggy, but I can't figure out whyCode: http://ift.tt/2vjtTA2 Name: app.jsUse: This file handles incoming messages, and a few other things.Potential Problems? I'm just not sure about my code style here, (I like no semicolons though), basically I just don't know if what I'm doing is actually good practice and best for performance. I feel like I'm not using async/await to it's full potential, and sometimes the bot seems to leak ram and it would probably come from this file.Code: http://ift.tt/2uJ27jr you could help me learn by giving me an honest review/advice, I'd really appreciate it! <3

Node.js rapid upskill

I am an experienced ASP.NET developer. Currently I am working on an inherited and very poorly designed and implemented .NET MVC site that needs to be rebuilt, especially the back-end.Our senior solution architects are pushing heavily for using node.js to create RESTful api microservices for the back-end while initially leaving the front-end largely untouched. The idea is to gradually move towards something resembling the MEAN stack, but there is still a lot of analysis that needs to be completed to determine the most appropriate solution design.Now, conceptually I have no issue with using something like node.js. I've been interested in it for a while and completed some beginner tutorials online, but that the only experience I have.I know it depends on a myriad of different factors like the complexity of the app and the individual developers level of overall competence, but what is the feasibility of going "YOLO: I'll figure it out as I go along and I'll be able to deliver an initial (if not yet necessarily complete) product within a month or two".

Using Node to act as a middleman between browser and mongoDB

Hey there,I've never used node before and a bit stuck. I'm trying to populate some graphs in a browser using data in a mongoDB collection. I've read around and using Node to assist with this seemed the way to go. I am a bit unfamiliar with how it works and was hoping for some hints.var http = require('http'); var client = require('mongodb').client; var url = "mongodb://*removed*"; client.connect(url, function(err, db) { if (err) throw err; var query = {id : "*removed*"}; db.collection("*removed*").find(query).toArray(function(err, result) { if (err) throw err; console.log(result); db.close(); }); }); I found this example online and is working fine. I'm a bit confused by two points:Does this file sit on the server with the Db and I just call this file?How can I alter query so that I can search whatever I want from the browser and have it return?I'm still searching for solutions on the second one but I'm not sure how the node file is situated. Any help would be appreciated.Thanks!

Best way to unit test database access?

I keep hitting up against this, and I keep thinking that there must be a solution to this. So, here goes. What are the recommended ways to unit test your DAO code?Specifically, how do you test that your code is executing the correct SQL, getting back the expected values from the database, and generally doing the right thing?The examples that I keep finding all have problems with them:Don't bother - acceptance tests will cover it. All well and good if you have good acceptance test coverage, but even then you're leaving until the last minute something that could be done earlierRewire / Proxyquire / etc the database module (e.g. pg). This works, but it often assumes that you're using pg directly in your DAO code and not going through some intermediate layer. (I've got a module of my own that exposes a single query method which does logging and returns the result as a Promise). Yes, this module could be Rewire-d but then how do you test this layer? This also means that you are asserting on the exact SQL string, which has problems if you are using some tool like Squel.js that writes it for you.Run a real database to test against. This implies that every developer has the database running locally, and if you're not careful you get leakage between tests which is very bad. I could do this using Docker - I do that already for acceptance tests - but it then means that unit tests can only be run from Grunt, not from the IDE.My current thinking is that 2b is the best that can be achieved, but it feels like it should be possible to do better.

Fetch examples for a CRUD app?

I'm finishing up a CRUD application and have come to the stage of implementing the update and delete functions on the front end (the routes are already complete). I'm not using a framework and I'm really struggling with how to write this part. Fetch seems to be the most simple way, but I haven't seen any direct examples (so much Angular...) and I'm having a hard time figuring out how to write the requests. I've read the documentation on MDN, but I guess I'm just not grasping how to apply the specifics. Can anyone point me in the direction of some specifics for PUT and DELETE requests?

Dynamic CSS using handlebars values?

Hey guys, sorry if this is a bit of a noob Q. I'm a beginner to html/js/css.I'm trying to create a HandleBars template of a crowdfunding thermometer. My problem is that I need the dynamic value to determine the width of the progress bar inside the Handlebars template, which requires CSS. I'm confused about the concept of dynamic CSS or whether it's possible.Effectively, the progress on the thermometer is based on an aggregated value called from Google Sheets, which is plugged into HandleBars.I need the width of the 'progress' div to be equal to percComplete.Javascriptvar RBITemplate = Handlebars.compile($('#team-rbi-template').html()); $('#total').sheetrock({ url: mySpreadsheet, query: "select sum(B)/100 where (A = 'Donate $2 to Test Campaign')", labels: ['percComplete'], rowTemplate: RBITemplate }); Handlebars HTML template - here's where I'm stuck

AJAX security in Express?

So for a personal app I'm writing I'm using express with auth0 for authentication (why reinvent the wheel?) and passport for authorization.There is a part of my app where I'd like the user to be able to POST via AJAX. I'm using fetch to send the POST request to the appropriate route and it works fine and dandy.My issue is that anyone can access this route. I've set up some really basic but easily broken protection inside the route, but I don't think that is good enough. Essentially, I'm just checking that the request is referred from within the app.However, this doesn't check that the user is logged in, and it uses the current user id being passed down from the server to assign the content created by the POST request as the owner of the content. So anyone with a working knowledge of the system could theoretically assign new content to anyone's account so long as they know the user's id.I tried setting up ensureLoggedIn as middleware on my router for the associated AJAX route. But since the client is passing the request via AJAX it doesn't have the token passed along with it...resulting in the AJAX request being redirected to the login page.I've been googling for days and haven't figured this out. Anyone here who can help?

Why do people hide all class variables behind getters?

I have seen the following pattern several times:class Cat { constructor(id, name, species) { this._id = id; this._name = name; this._species = new Map(species); } get id() { return this._id; } get name() { return this._name; } get species() { return this._species; } } I understand that this is implying that id, name, and species are supposed to be read only. However at the same time, it just feels like it bloats the code. I can understand if your creating a getter for a case where you are computing the property value on the fly.However is this really that much better than this:class Cat { constructor(id, name, species) { this.id = id; this.name = name; this.species = species; } } I am going through code where a class has 15+ getters for nothing other than properties passed into the object, which feels like a huge waste. Is there some better reason for this?

Noob question, sequelize

I am trying to use sequelize in a pretty simple setup, but I am making sure there isn't a better way to achieve what I want to achieve.models.prices.findOrCreate({ where: { price: product.price, sourceId: ???, productId: ??? } }); In this scenario both sourceId and productId are foreign keys. Both of these keys have to be queried. Currently I have a (what I feel) is a bootleg way of fixing this issue, I have multiple nested findOne queries. This looks ugly and doesn't feel elegant.So, my question is: Is there a better way to access the sourceId and productId without nesting a ton of these queries?productId would need a query searching for SKU and retrieving ID in model productssourceId would need a query searching for a string and retrieve the ID in model sourcesSorry if this seems like a dumb question, I just come from a Django background. This is usually pretty basic/built-in stuff, making sure I am not missing something.

How do I get an OAuth 1A token from my node app?

I want to use the tumblr api in my node app, and need OAuth 1a to authorize. The official tumblr node library requires an existing Token and Token Secret, so I need to request one. I checked out node-oauth, but it doesn't seem to have any (documented) way to get a new OAuth 1 token. I've spent a few hours trying desperately to figure out how to get a new token for a user.My goal is to retrieve a URL for this sort of page which I can open in the user's browser, which should then send a request to my API callback containing the token, but I'm completely lost. Could somebody point me in the right direction?I've tried this code, which I thought would result in the token being sent to my callback URL, but the logs on the server I set up to receive the callback show absolutely nothing. (And, in retrospect, I completely ignored the fact that the user needs to see an authorization prompt in their browser for this to work.)const oauth = require('oauth') const oa = new oauth.OAuth( 'http://ift.tt/1e3TrA7', 'http://ift.tt/Lohona', '< the consumer key >', '< the consumer secret >', '1.0A', null, 'HMAC-SHA1' ) oa.getOAuthAccessToken('', {'grant_type':'client_credentials'},(e) => {console.log(e)})

Critique my micro-service setup

I'm making a nodejs app with basic auth functionality, and I decided to build it with a micro-service approach.Infrastructure: Digital oceannode1: { nginx-loadbalancer + nodejs-app } node2: { nodejs-app } node3: { database }It's pretty barebones, but it definitely works. It allows zero-downtime deployments since the load balancer will redirect traffic to the working nodes. And during heavy load, I can easily spin up more nodes.Is this a good setup? What's the reason to use kubernates etc? The reason I haven't used docker is because pm2 does the same thing, I just need to do a somewhat longer (still easy) setup. I don't think the docker-swarm autoscaling works with the digital ocean API either.

How do I start in this pile of unsorted Javascript frameworks and tutorials?

I am a young and new web developer and I got super interested in Node and how it uses javascript for the backend and generally speeds up web apps and a million of other benefits of learning it. But I just cannot grasp one thing - where the hell do I start? We got front-end frameworks, back-end, front-end and more back-end.I have previously self taught myself C++, C#, Java and they are all straightforward, with their own libraries and apis. But with Node it's a whole different story, let's say I pick React for the front-end, then what the heck do I pick for the back-end? The old articles suggest, that, the newer ones say that use whatever you want. But how can I choose, if I am in a room with a bunch of books, that cover pretty much the same thing in their own unique way.tl;dr - Frustrated with the insane amounts of content and frameworks for Node and looking for an answer on where to begin in this mess.

Async / Await and callbacks

Below is an example.// listener.jsconst amqp = require('amqplib') async function newMsg(){ try{ const connection = await amqp.connect(${addresss}) const channel = await connection.createChannel() channel.assertQueue('queueName', msg => { let msgBody = JSON.parse(msg.content.toString()) channel.ack(msg) return msgBody }) }catch(e){ throw new Error(e) } } module.exports = newMsg I then have a seperate module consuming these messages and processing them;// someService.jsconst newMsg = require('./listener') async function listen(){ try{ let scrapeRequest = await newMsg() // ... do things with the message }catch(e){ console.warn(e) } listen() } Running someService.js doesn't seem to wait on a msg being produced. If newMsg() only returns once the channel.assertQueue callback fires, and newMsg being an async function means it returns as a promise, why is the code running to completion early?Are there any good examples of async / await with a message queue? It seems tricky to structure, especially if I try to ack messages outside of the inital newMsg function.
