Created a react application with create-react-app along with typescript as the template.
Trying to use optional chaining:
const inputRef = useRef<HTMLInputElement | null>(null);
const handleClick = () => {
if(inputRef) {
inputRef?.current?.click();
}
};
On load my application gives the error:

You haven't stated what version of create-react-app you're using, and the latest version should support optional chaining out of the box, but you can try adding support for optional chaining directly by including the associated babel plugin #babel/plugin-proposal-optional-chaining.
First npm i #babel/plugin-proposal-optional-chaining --save-dev.
Then update your webpack config module.rules for babel-loader.

To start off, this is my first post on stackoverflow so I hope I'm doing it right...
So my Webpack alliases work in browser, but not in node
I have a package (let's call it Services) with a subfolder dev and another project (let's call it MobX) which uses Services. In Mobx, I have a webpack configuration which is supposed, in development mode, change the paths of Services to have access to the subfolder dev instead.
Here's a sample of the code :
const devConfig = {
...commonConfig,
mode: "development",
devtool: "cheap-module-source-map",
entry: "./src/lib/index.ts",
output: {
path: outputDir,
library: name,
libraryTarget: "umd",
globalObject: "this",
},
optimization: {
minimize: false,
},
plugins: [...commonConfig.plugins, forkTsCheckerWebpackPlugin],
resolve: {
...commonConfig.resolve,
alias: {
"#intuition/services-apis$": "#intuition/services-apis/dev",
},
},
};
const devConfigNode = {
...devConfig,
target: ["node"],
name: "node",
output: {
...devConfig.output,
filename: splitChunks ? "[name].[contenthash].node.js" : "index.node.js",
},
};
const devConfigBrowser = {
...devConfig,
target: ["web", "es5"],
name: "browser",
output: {
...devConfig.output,
filename: splitChunks ? "[name].[contenthash].browser.js" : "index.browser.js",
},
};
I don't understand why, in node, it doesn't go into #intuition/services-apis/dev. In works fine in browser but no matter what I do, in node, it doesn't work. I have been at this day for days now and I can't seem to figure it out.
If my explanation wasn't clear enough and needs more details, please do not hesitate to ask any question.
I'm building a chrome extension using Vite as my build tool. The main problem is during minification and mangling there are a lot of global variables created. After injecting my script to the page they conflict with already defined variables on window object.
I imagine the perfect solution would be to have my entire script wrapped in IIFE. I tried using esbuild.format = 'iife'. The resulting build is in fact wrapped in IIFE, however all the imports are not inlined. Instead resulting script is like 15 lines long with a bunch of require statements, which obviously does not work in the browser.
This is my config file:
export default defineConfig({
plugins: [
vue(),
],
esbuild: {
format: 'iife',
},
build: {
emptyOutDir: false,
rollupOptions: {
input: resolve(__dirname, './src/web/index.ts'),
output: {
dir: resolve(__dirname, './dist'),
entryFileNames: 'web.js',
assetFileNames: 'style.css',
},
},
},
resolve: {
alias: {
'#': resolve(__dirname, './src'),
},
},
});
I'm currently using this hack so to say to wrap my build in IIFE (for this I removed the esbuild.format option).
Hey I am doing the exact same thing! And I also noticed the unminified variables and functions can clash with random code in a webpage.
From what I researched myself on this topic, you shouldn't change esbuild build options with Vite as that will prevent Rollup from transforming the output. Instead, you should use format: 'iife' in the rollupOptions of your vite.config. However, in my case (and yours I believe), I have to output multiple bundles since the extension code can't share modules amongst each other. Which will crash when you set the format to 'iife' due to:
Invalid value for option "output.inlineDynamicImports" - multiple inputs are not supported when "output.inlineDynamicImports" is true.
The only solution in my case seems to be to either use multiple vite.configs (I already have two) for each of my bundle with single input entry point and format as 'iife'. Or, as you did, just write the self-invoking function yourself with some hacky script. Seems though there aren't any perfect solutions as of now.
EDIT: Okay, got it working. This is my vite.config.ts (the project):
import { defineConfig } from 'vite'
import { svelte } from '#sveltejs/vite-plugin-svelte'
import tsconfigPaths from 'vite-tsconfig-paths'
import path from 'path'
/** #type {import('vite').UserConfig} */
export default defineConfig({
plugins: [svelte({}), tsconfigPaths()],
build: {
minify: false,
rollupOptions: {
output: {
chunkFileNames: '[name].js',
entryFileNames: '[name].js'
},
input: {
inject: path.resolve('./src/inject.ts'),
proxy: path.resolve('./src/proxy.ts'),
'pop-up': path.resolve('./pop-up.html')
},
plugins: [
{
name: 'wrap-in-iife',
generateBundle(outputOptions, bundle) {
Object.keys(bundle).forEach((fileName) => {
const file = bundle[fileName]
if (fileName.slice(-3) === '.js' && 'code' in file) {
file.code = `(() => {\n${file.code}})()`
}
})
}
}
]
}
}
})
Okay, I made it working with this config:
export default defineConfig({
plugins: [
vue(),
],
build: {
emptyOutDir: false,
rollupOptions: {
input: resolve(__dirname, './src/web/index.ts'),
output: {
format: 'iife',
dir: resolve(__dirname, './dist'),
entryFileNames: 'web.js',
assetFileNames: 'style.css',
},
},
},
resolve: {
alias: {
'#': resolve(__dirname, './src'),
},
},
});
They key part is format: 'iife' inside build.rollupOptions.output.
Sorry I'm quite new to Nuxt & Webpack. I have a Nuxt project in which everything works fine running yarn dev. But when I build using yarn build -> yarn generate, the .css files I reference in the node_modules directory (dropzone.css, flatpickr.css etc) are never included and break the site. I've tried everything but can't figure out what I'm doing wrong. Can someone point me in the right direction? Currently running Nuxt v2.11.0 with Tailwind.css. This is my nuxt.config.js file which is mostly boilerplate -
require('dotenv').config()

It's pretty hard to answer this without having the full project to build and run. I assume you're not using a separate webpack config file when building for production, otherwise you would have added that to the question. You seem to be using the correct syntax in the config file, so I'm guessing your css file paths are not quite right. They kinda look like the old way of doing things, you may want to confirm that they're not out of date. This old-ish github issue goes through the various things you could try, on of them being let nuxt find the "compiled" version of the css automatically for you like this:
css: [
'nuxt-dropzone',
...etc
],
Try removing all of the 3rd party css files and add them back one at a time, after the previous one works.
This example is from the official docs:
export default {
css: [
// Load a Node.js module directly (here it's a Sass file)
'bulma',
// CSS file in the project
'#/assets/css/main.css',
// SCSS file in the project
'#/assets/css/main.scss'
]
