I am using webpack to build my files. I'm not sure if I don't understand the workflow or not. I am trying to code split my files and then have them loaded on routes that need them. But the starter pack I am using has the webpack config placing them in the index.html file so they are all loaded on app init.
Is it intended that we would be running a node server in production for async component loading? Or should webpack not be putting these into the index file?
Async chunks are simply added in <script src="..." async></script> by JavaScript on the client side - so there is nothing to do with backend. Webpack is server agnostic, you can use node, java, php, etc.
Probably you are confused with node in most starter kits, because node is the most lightweight and quick to configure backend out of the box. Also if you install project with NPM there is guarantee that you have got node installed on your system. That's why node is so popular in starter kits.

This may be a dumb question, but is the default react app (created using npm create-react-app my-app) using node.js? I am confused because in my web development class at university, I had to download node.js to create react applications. However, I didn't have to do anything like creating a server or initiating a node.js file, which is described in w3school's node.js tutorial. Because of this, I found out that I don't even really know what node is used for, besides downloading packages like redux and whatnot.
create-react-app uses node.js for all of its dev tooling. Likewise, a lot of the tools you'll use in the React ecosystem (like webpack, prettier, npm), all run on top of node.js as well).
You'll most probably build your react app to a static file, in which case the production output will not require node.js, it will be html and javascript assets that can be served directly to a client.
Hope that helps! Let me know if you have other specific questions
Node.js is used for server-side while React.js is for the front-end part. So, no, you don't need Node.js.
Under development mode, yes. Create react app runs NodeJs with Webpack Dev Server to allow you get feedback when modifing files, start or stop the server.
Hi I'm developing a project and for some reasons I am not able to use any webpack and node modules. I also cannot use any cdn. The vue project will only contain client side components. I don't have to consider the backend part, routing etc. The size of the project matters so I am not allowed to use node modules. How can I create a client-side only vue project without node modules and npm?
You can download Vue.js and use it locally in a project.
Development version (with debug mode and all warnings).
Production version (no warnings no debug)
After that you can just add it via a script tag:
<script src="your-vue-directory/vue.js"></script>
And you ready to go.
According to docs you can use CDN
<script src="https://cdn.jsdelivr.net/npm/vue#2.6.12"></script>
So, I'm heading to new territory in web dev.
I set up a basic npm project using npm init in my project folder. I don't have angular, react or any other Dev framework running. Basically I want to get started with some npm packages to easily update the things I need.
For my first test I picked bootstrap and font-awesome.
For testing I have a http-server running and displaying a index.html file from the public folder.
The site I'm displaying is a basic html site for now. How do I actually implementy packages the right way? Using <link rel="stylesheet" href="/path/to/node_modules/..."> is one option but not actually the way it is done, right?
Or will it be repacked once I'm ready for production. Since node_modules is not going to be transferred to the prod server.
Thank you very much in advance!
there is a difference between running javascript in nodejs and the browser javascript engine.
although nodejs is built on top of v8 javascript engine, nodejs is different in some ways, here are 2 of them:
nodejs is used mainly in server-side programming, where javascript is used for client-side
nodejs has builtin libraries which are not in the javascript specifications
if you are developing a client-side in nodejs (using react, angular or any other client-side frameworks), you will have to "convert" (a process called transpiling) it to run within the browser.
there are several tools which can help you in the process of transpiling your code. some famous ones are webpack and parcel in conjunction with babel (to pollyfill) to "build" your project and yield a bundled (few javascript file, usually one, that bundles all the javascript code into one of more files) javascript file(s), which are loaded by the webpage.
as you can see, once the project is bundled, node_modules directory has no use -- exactly what you want.
I am writing application by using Python/Flask as the API back-end, and want to separate the front-end (browser-based) as an individual project (VueJS). I've read about Webpack, but I can't find any best practice to start, such as: can we use NPM to manage dependencies, use webpack for front-end not using an Node app as an entry ...
Thanks alot
WebPack isn't a framework.
It's something that a task runner.
Exemple: You use SASS, you want something that compile all your sass file in CSS file. You create a task and webpack have a task now. And you can ask him to automaticaly compile the file when change.
Maybe what you want it's more have two project:
One who handle the data an may available with an api
One who is the web ui for the user who get the data and format it in a beautifull UI
Webpack won't be your solution. Continue with your VueJS and look at VueX for your data handling browser side.
I am using angular2 with nodejs, how about using apache/xampp. will it support or nodejs npm server is mandatory for angular2
Considering for development ,NodeJS is Mandatory for angular2 !
let me tell you why?
Angular2 comes with typescript support which is transpiled into javascript.
NodeJS offers typings & other dependency packages like SystemJS,RxJS which helps angular2 do thye magic you call Angular.
Though you could run angular2 apps in Xampp but recommended approach will be with NodeJS as it offers a lot more flexibility & framework support for development.
for eg. Angular-Cli is node module which helps you setup your project really fast.
On top of that node gives you flexibilty to add third party libraries easily into your project.
You can use Xampp but then you will need your server to load transpiler manually which will transpile ts files into javascript files as currently there is no support in Xampp as far as I know and that will be quite a task to do.
So I will go with NodeJS on this.
For production:
once you build bundle from your application , it can be deployed to any server which runs javascript. So in that case NodeJS is not required.
It depends on what we are talking about.
For Development you must have NodeJS on your dev machine to load all libs, transpile TS, prepare build files and so on.
For Production server you can use whatever you want, if you have already prepared js bundles with all deps and your app, just static files with index.html, css, js, jpg files and so on..
I will also recommend you to go with Oleg Barinov.More over Angular2 applications only consist of static files so they can be serve by any static Web servers or server applications that can define static folders (Express, ...)
