i'm working on React Project Javascript universal (Express.js as server)
in the production build, i'm using webpack and babel as a bundling and transpiler.
Everything work fine,
However, i'm thinking that, those bundles are actually just static javascript, styles and html.
Can we upload it to Amazon S3 and link it with Cloudfront and make these files available over CDN?
I try googling searching for webpack and CDN but didn't find any useful information.
Or did i misunderstand something? Will it work like what i think? And can we automate this using just webpack cli ?
Please advise,
Webpack is mostly concerned about the building (and bundling) of your assets. What you do with them/where you host them is up to you, and you might want to look into some kind of CI process/tool to manage automated deployments for you, once the bundles are built. Webpack doesn't (afaik) handle deployment.

Thanks,
In the long term, you would want to configure your Webpack and use it to preprocess your saas files. If you can please share your Webpack config and the error message maybe some one can help.
Right now you can use a tool like Koala, which will watch and spit out CSS files. Now you can use this css file in your project without making any changes to the webpack config.
I generally use it for light html/css websites.
I come from a background in Angular, but I wanted to start learning React. I want to make a React front-end for a nodejs Express web service.
In Angular, I could simply build the source code into a static folder with a standard index.html, and it can be deployed on any web server. With React however, every tutorial I see is about running React in its own server using create-react-app and npm start.
I know you can also just use script tags to import the React framework in a static page, but then you can't use JSX syntax, and I would like to. Is it possible to simply build a React project into a static folder with an index.html that can be deployed on any web server?
Yep, you can do what you're describing. If you want to use JSX syntax, you'll need Babel, which transpiles it into standard JavaScript.
You can avoid the complexities of setting it up by using create-react-app to create the app, then running npm build instead of npm start. This will compile everything into a build directory, complete with index.html.
CRA uses its server for development purposes. You don't need CRA for using React of course. But, as your app getting bigger and bigger you will need some more extra tools. For example you want to see your code instantly without refreshing your browser. Here comes the dev server and hot reloading.
CRA uses Webpack behind the scenes. It is a great tool for bundling (obviously) all your files (including css), minifying, uglifying, optimizing your code etc.
For simple code or testing purposes using one file and attaching React and Babel to your file could be enough but for real apps you will need more. Either you will use something like Webpack on your own or you will use CRA and let it do all the extra stuff for you.
Recently I started learning react and I saw a tutorial where they used Webpack to create the production and development builds. But there was no explanation on what the difference between those two builds is and which one you have to use when. I searched the internet but didn't find anything that helped me. Does anyone have a tutorial or an explanation that I missed/didn't read?
The development build is used - as the name suggests - for development reasons. You have Source Maps, debugging and often times hot reloading ability in those builds.
The production build, on the other hand, runs in production mode which means this is the code running on your client's machine. The production build runs uglify and builds your source files into one or multiple minimized files. It also extracts CSS and images and of course any other sources you're loading with Webpack. There's also no hot reloading included. Source Maps might be included as separate files depending on your webpack devtool settings.
What specifically separates production from development is dependent on your preferences and requirements, which means it pretty much depends on what you write in your Webpack configuration.
The webpack-production documentation is very straight-forward.
Also, the article Webpack 3 + React — Production build tips describes the process of creating production builds for React with Webpack pretty good.
The very basic difference is that Production Build has ugly, minified(compressed) version of your javascript code, so this makes rendering of file on end user's browser very quick and performance enhancing.
You can also verify if production build is being used in the website by applying a google plugin extension, which when activated on your browser, will always tell you if the website is using react js on the front end and also tells whether the build type is production or development.
when react is development build,
production-ready versions of React and React DOM as single files are available as well,
<script src="https://unpkg.com/react#16/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom#16/umd/react-dom.production.min.js"></script>
NOTE: Remember that only React files ending with .production.min.js are suitable for production.
The production and development build come into the picture just because of performance impact in real life deployed the application. Also, it happens that the location where the application is deployed is another continent altogether, so rendering development build js files on UI will take a hell of a time as compared to production version which is very crisp, compact, compressed, uglified for better user experience and loading on UI. for information CLICK HERE
react.development.js provides us extra features like debugging, hmr(Hot module reloading) and lots of other stuffs that you might
use while developing app with the help of bundlers like webpack, parcel, vite. This bundler bundles and minifies our code to be
deployed on production
These minified files will be deployed on production which removes lots of unnecessary files which will not be used by our app
for this we have react.production.js to make our much faster(as bundlers and lots of other files have done there work and are not required now)
My case is that we have application with stack: AngularJS and ES5 and we want to use webpack. Migration of all of the .js files (rewrite it to ES6 Classes etc.) is a big problem because of the size of the project. Is there any way to migrate it to webpack without making full refactor? The situation that we use webpack with new modules and the other modules are only plugged to webpack (somehow) with old dependency injection etc. would be satisfactory. Do you have any idea how to do it?
Here is my project structure
My goal is to generate stylus files into css, compile the jade files into HTML and image optimization. There is nothing much happening in the js folder, the js files need to be minified and in some instances, need to be combined into a single js file into dist/js folder. However I intend to use AngularJS, KendoUI and BrowserSync onto this project. I usually use Gulp to achieve the task. I would like to know if Webpack can make my life easier. Can I achieve the same using Webpack instead of Gulp. Is it worth the effort?
Yes you can use webpack!
Webpack can do much more then gulp, gulp is a only task runner on the other hand webpack is a bundler for modules. The main purpose is to bundle JavaScript files for usage in a browser, yet it is also capable of transforming, bundling, or packaging just about any resource or asset.
I used gulp before webpack and i have to admit it did the job but was very complicated for with all those tasks and now i let webpack to do the hard job :-)
