PostCSS VS vite

the plugins in the official PostCSS website were old like IE6 or the marquee tag, and

Hello internet. I just published a new blog post on how to implement dark mode with SvelteKit, optionally with PostCSS and TailwindCSS:

There are many frontend tools available for this purpose. For example, PostCSS is a popular CSS processor that can combine and minimize your code. With the right plugin, it can even fix your code for compatibility issues, making sure your CSS styles work for all browsers.

I use PostCSS to extend CSS’s features and to add a few things that make writing styles a little more convenient, but it could easily be swapped for another preprocessor like Sass or vanilla CSS. It’s up to you. You can view my PostCSS config here.

Code transpilation isn't specific to JavaScript, You can also add a level of transformation to your CSS source using tools like post-css. Most languages with a fairly mature ecosystem will probably have some tools to help with code transformation.

In large projects, it is still a good idea to use PostCSS, which will translate new CSS features to something that browsers understand today.

LiveCodes provides many of the commonly used developer tools. These include Monaco editor (that powers VS Code), Prettier, Emmet, Vim/Emacs modes, Babel, TypeScript, SCSS, Less, PostCSS, Jest and Testing Library, among others. All these tools run seamlessly in the browser without any installations or configurations. It feels like a very light-weight version of your own local development environment including the keyboard shortcuts, IntelliSense and code navigation features.

Usually, one of the first things I do on creating a new web app is to throw a UI library in to help style components. There are several UI libraries that can be used by Svelte, but in this case I went with daisyUI because it's a fairly popular UI library which includes tailwind. To install daisyUI, you first need to install tailwind. There's a few different ways to do this (such as this guide), but the easiest way I've found is the following command, which also adds PostCSS and AutoPrefixer:

Vanilla CSS has taken a similar path with ambitious working drafts, better browser support, and PostCSS to fill the gap for user agents lagging behind. So why is Sass/SCSS still so popular? Maybe we go so used to it that we might have forgotten what problems it was meant to solve in the first place.

import { defineConfig } from 'vite' import react from '@vitejs/plugin-react-swc' import path from 'path' // https://vitejs.dev/config/ export default defineConfig({ plugins: [react()], server: { port: 3000 }, css: { devSourcemap: true }, resolve: { alias: { '~': path.resolve(__dirname, './src') } } })

I am currently utilizing Vite:

Homepage: https://vitejs.dev/

Without any adding any dependencies you can connect react props to raw css at runtime with nothing but css variables (aka "custom properties"). If you add CSS modules on top you don't have to worry about affecting the global scope so components created in this way can be truly modular and transferrable. I use this with vite.

Little confused as to why it has vite in it‘s name, it seems unrelated to https://vitejs.dev/

it says in their docs that they recommend Vite https://vitejs.dev/

it goes like this.

1. you create a repo folder, you cd into it.

2. you create a client template using vite which can be plain typescript, or uses frameworks such as react or vue, at https://vitejs.dev/guide/

3. you cd in that client directory, you npm install, then you npm run dev, it should show you that it works at localhost:5173

4. you follow the instructions on your url, you do npm install @web3modal/wagmi @wagmi/core @wagmi/connectors viem

5. you follow the further instructions.

> It seems like this is for npm or yarn to pull from a remote repository maintained by @wagmi for instance. But then what?

you install the wagmi modules, then you import them in your js code, those code can run upon being loaded or upon user actions such as button clicks

> Do I just symlink to the node_modules directory somehow? Use browserify? Or these days I'd use webpack or whatever the cool kids are using these days?

no need for those. browserify is old school way of transpiling commonjs modules into browser-compatible modules. webpack is similar. vite replaces both webpack and browserify. vite also uses esbuild and swc under the hood which replaces babel.

> I totally get how node package management works ... for NODE. But all these client-side JS projects these days have docs that are clearly for the client-side but the ES2015 module examples they show seem to leave out all instructions for how to actually get the files there, as if it's obvious.

pretty much similar actually. except on client-side, you have src and dist folders. when you run "npm run build" vite will compile the src dir into dist dir. the outputs are the static files that you can serve with any http server such as npx serve, or caddy, or anything really.

> What gives? And finally, what exactly does "browserify" do these days, since I think Node supports both ES modules and and CJS modules? I also see sometimes UMD universal modules

vite supports both ecmascript modules and commonjs modules. but these days you'll just want to stick with ecmascript which makes your code consistently use import and export syntax, and you get the extra benefit of it working well with your vscode intellisense.

> In short, I'm a bit confused how to use package management properly with browsers in 2024: https://modern-web.dev/guides/going-buildless/es-modules/

if people want plain js there is unpkg.com and esm.sh way, but the vite route is the best for you as it's recommended and tested by the providers of your modules.

> And finally, if you answer this, can you spare a word about typescript? Do we still need to use Babel and Webpack together to transpile it to JS, and minify and tree-shake, or what?

I recommend typescript, as it gives you better type-safety and better intellisense, but it really depends. If you're new to it, it can slow you down at first. But as your project grows you'll eventually see the value of it. In vite there are options to scaffold your project in pure js or ts.

First you have to know that all those react projects are created using Vite, and for each of them, you need change the vite.config.ts file by adding the following configuration:

CSSHooks works with React, Prereact, Solid.js, and Qwik, and we’re going to use Vite with the React configuration. First, let's create a project called css-hooks and install Vite:

JavaScript React Flowbite Tailwind Firebase - Auth, Database, and Hosting Vite

For this full-stack single-page app, you'll use Vite.js as your frontend build tool and the react-beautiful-dnd package for draggable items.
