I am using Webpack 4 to build a simple website with an express backend. Now that I am implementing a custom element I am confronted with an issue regarding the shadow DOM.
The issue is as follows: all of my SCSS is being combined into one CSS output file. I need it to remain separate so that the custom element's style can be dynamically added to the shadow DOM, when the element is connected.
I am using extract-css-chunks-webpack-plugin (which I think the issue is with), css-loader, postcss-preset-env and sass-loader to handle all SCSS within the app/site.
All my searching thus far has simply lead me to the exact opposite of what I need (people trying to combine their SCSS).
I understand I could build the custom element separately and then just import it into the project after it has been built but that means managing two building environments and then having to version control across both -- seems like a lot of overhead.
The project's folder structure is as follows:
root
--src/
----assets/
------js/
--------main.js
------scss/
--------main.scss
------web-components/
--------contact-modal.js
--------scss/
----------modal.scss
My current webpack dev config is as follows:
**omitted**
module: {
rules: [{
test: /\.(scss)$/,
use: [{
loader: ExtractCssChunksPlugin.loader,
options: {
hot: true,
}
},
{
loader: 'css-loader',
options: {
sourceMap: true,
}
},
{
loader: 'postcss-loader',
options: {
indent: 'postcss',
plugins: () => postcssEnv(),
sourceMap: 'inline',
},
},
{
loader: 'sass-loader',
options: {
sourceMap: true
}
}
]
},
**omitted**
plugins: [
new webpack.HotModuleReplacementPlugin(),
new HtmlWebpackPlugin({
template: 'src/views/pages/index.ejs',
filename: 'index.html',
}),
new ExtractCssChunksPlugin({
filename: 'assets/css/[name].css',
chunkFilename: 'assets/css/[id].css',
})
]
If there is a better way of using custom elements which I have overlooked I'd appreciate any feedback.
Thank you in advance.
EDIT:
Figure it would be beneficial to state that I am including the modal.scss file with an import in the contact-modal.js file.
I'm assuming modal.scss is importing main.scss? If that's so, then your issue is with the Sass compiler itself, not webpack. Depending on what's in modal.scss, you may want to use #use instead
Edit 1:
If you're adding your compiled css in the shadow DOM in let's say a <style> tag, you can replace the ExtractCSSChunks loader with something like to-string-loader. In your js, import style from "modal.scss"; will have the compiled output in a string that you can use.
In order to solve my issue while still using SCSS (to allow me to use vendor prefixing from postcss-loader) I ended up prefixing my modal scss with a .modal flag so modal.scss became main.modal.scss.
I then edited my webpack config to have two rules for scss files: One which only affected .scss files and one which affected .modal.scss.
Then, in my modal I imported the scss with a normal import style from './main.modal.scss'; to then append it to the shadow DOM in a <style></style> element.
Code is as follows:
New SCSS rule
test: /(\.modal\.scss)$/,
use: [
'css-loader',
{
loader: 'postcss-loader',
options: {
plugins: () => [ postcssPresetEnv() ],
sourceMap: 'inline'
}
},
'sass-loader'
]
Modified old SCSS rule
test: /(?<!\.modal)\.scss$/,
use: [{
loader: ExtractCSSChunksPlugin.loader,
options: {
hot: true,
}
},
{
loader: 'css-loader',
options: {
sourceMap: true,
importLoaders: 3
}
},
{
loader: 'postcss-loader',
options: {
ident: 'postcss',
plugins: () => [
postcssPresetEnv()
],
sourceMap: 'inline'
}
},
{
loader: 'sass-loader',
options: {
sourceMap: true,
}
}
]
In my contact-modal.js file
import CSS from './scss/main.modal.scss';
// ... omitted ...
connectedCallback() {
// ... omitted ...
const style = document.createElement('style');
style.innerHTML = CSS.toString();
this.shadow.appendChild(style);
// ... omitted ...
}
I have a component which loads SVG files from a remote source using URLs like this:
<img src="//cdn.image-hosting.com/sample.svg" />
As you can see, the URL starts with //. In development, everything works as expected, however, when I build the application and run the production version, Electron tries to load those URLs from the disk (file://) instead of requesting them from the remote server.
I'm using Webpack, but that does not change the URL; it is still the same in production as in development.
This is my configuration for the production build:
// Webpack uses `publicPath` to determine where the app is being served from.
// It requires a trailing slash, or the file assets will get an incorrect path.
// const publicPath = paths.servedPath;
const publicPath = './';
// Some apps do not use client-side routing with pushState.
// For these, "homepage" can be set to "." to enable relative asset paths.
const shouldUseRelativeAssetPaths = true // publicPath === './';
// Source maps are resource heavy and can cause out of memory issue for large source files.
const shouldUseSourceMap = process.env.GENERATE_SOURCEMAP !== 'false';
// Some apps do not need the benefits of saving a web request, so not inlining the chunk
// makes for a smoother build process.
const shouldInlineRuntimeChunk = process.env.INLINE_RUNTIME_CHUNK !== 'false';
// `publicUrl` is just like `publicPath`, but we will provide it to our app
// as %PUBLIC_URL% in `index.html` and `process.env.PUBLIC_URL` in JavaScript.
// Omit trailing slash as %PUBLIC_URL%/xyz looks better than %PUBLIC_URL%xyz.
const publicUrl = publicPath.slice(0, -1); // or '/' works
// Get environment variables to inject into our app.
const env = getClientEnvironment(publicUrl);
// Assert this just to be safe.
// Development builds of React are slow and not intended for production.
if (env.stringified['process.env'].NODE_ENV !== '"production"') {
throw new Error('Production builds must have NODE_ENV=production.');
}
// Check if TypeScript is setup
const useTypeScript = fs.existsSync(paths.appTsConfig);

I have done some research and came across this thread, however, I don't think that there is any solution given which is applicable to my problem.
How can I load those remote files from my production build?
As already stated in this comment over at the Atom.io thread you provided, by using // instead of, say, https:// you request the URL over the current protocol.
It could possibly be that when you load a file into an Electron window in development directly, Electron (or, specifically, Chromium, since Electron only builds on top of that) will assume that the current protocol is HTTP and hence load the file. But if you load the file from a packaged app, your HTML source might be loaded via file://, which makes your URL invalid.
I suggest to use HTTPs anyways (if the endpoint provides encryption). Even if it's "only an image", encrypted connections and traffic can basically do no harm.
Also refer to this explanation on so-called "protocol-relative URLs", which yours is.
The only thing I have in my entry JS file is:
import $ from 'jquery';
The jQuery JS file has the size of 29.5kb from jsdelivr.

I should also mention, that going into the output bundle.js it still has the jQuery comments.

Even though I'm calling webpack with the -p argument and have the UglifyJS plugin, but the rest of the file is minified and mangled. Any ideas?
Thanks!
Try to copy and paste minified jquery from your link. It's has size of 86.9 kb.
This link also show that jquery v3 minified file size is also around 80kb.
So you already have correct setup. Maybe your 29.5kb file size is minified+gzipped file.
The 29.5kb file size is definitely the minified+gzipped version as per the link Niyoko posted.
I would also recommend checking out Fuse-Box It brought down our project size from over 1mb to under 200kb (Vendor and App bundles combined). Very easy to get going as well and it is TypeScript first :) It takes the best features from a number of the more popular bundlers and brings them together and builds on those features.
