Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Do vite builds not automatically support typescript?
But when I start a production bundling + build process, which I guess is actually made with rollup, I see Unexpected token (Note that you need plugins to import files that are not JavaScript). Lookin around, it seems like this is a rollup error, not a vite error.

Migrating app from parcel to rollup
rollup v3.2.3 bundles ./src/index.js → dist/bundle.js... babelHelpers: 'bundled' option was used by default. It is recommended to configure this option explicitly, read more here: https://github.com/rollup/plugins/tree/master/packages/babel#babelhelpers [!] (plugin commonjs--resolver) SyntaxError: Unexpected token (12:2) in /Users/krishna404/codeProjects/All_SmartAgent/desktopSmartAgent/src/index.js src/index.js (12:2) 10: import { AdapterDateFns } from '@mui/x-date-pickers/AdapterDateFns'; 11: ReactDOM.render( 12: ^ 13:

Rollup Library Starter
Next, we need to tell Rollup which of the modules used in our code are external to our library. Together with @rollup/plugin-node-resolve, this ensures that Rollup doesn't bundle those dependencies into our final bundle. The function makeExternalPredicate() generates the list of package names specified in dependencies and peerDependencies in package.json. All credit for this and a big thank you goes out to Mateusz Burzyński for providing it in this issue:

I'd like to use Svelte with PHP with SSR and an island architecture. How would I go about doing this?
// If you have external dependencies installed from // npm, you'll most likely need these plugins. In // some cases you'll need additional configuration - // consult the documentation for details: // https://github.com/rollup/plugins/tree/master/packages/commonjs resolve({ browser: true, dedupe: ['svelte'], }), commonjs(), // In dev mode, call `npm run start` once // the bundle has been generated !production && serve(), // Watch the `public` directory and refresh the // browser on changes when not in production !production && livereload('public'), // If we're building for production (npm run build // instead of npm run dev), minify production && terser(), ], watch: { clearScreen: false, },

Is there a way I can conditionally choose which module I import at compile time?
Then in this case, if you don't want to use Vite's dynamic imports, you can conditionally use this plugin in your vite config under rollupOptions. https://github.com/rollup/plugins/tree/master/packages/inject. This way you won't even need to use env vars.

Svelte And Tailwind
compilerOptions: { // enable run-time checks when not in production dev: !production } }), // we'll extract any component CSS out into // a separate file - better for performance css({ output: 'bundle.css' }), // If you have external dependencies installed from // npm, you'll most likely need these plugins. In // some cases you'll need additional configuration - // consult the documentation for details: // https://github.com/rollup/plugins/tree/master/packages/commonjs resolve({ browser: true, dedupe: ['svelte'] }), commonjs(), // In dev mode, call \npm run start` once // the bundle has been generated !production && serve(), // Watch the `public` directory and refresh the // browser on changes when not in production !production && livereload('public'), // If we're building for production (npm run build // instead of npm run dev), minify production && terser() ], watch: { clearScreen: false } };`

How to use SVGs in React
In Webpack 5, this is (surprisingly) simple to setup. Parcel 2 handles this out of the box with a special import prefix. Rollup has an official plugin.

What does it take to support Node.js ESM?
The only workaround to have an isomorphic __dirname or __filename to be used for both "cjs" and "esm" without using build-time tools like @rollup/plugin-replace or esbuild "define" would be using a library like filedirname that does a trick inspecting error stacks, it's clearly not the cleanest solution.

Rollup Library Starter
This next one will help us reduce final bundle size by minifying the generated code. It's called rollup-plugin-terser and uses terser under the hood to minify the code.

Setting Up a JavaScript Build Process using Rollup
Generating a bundle that has many dependencies, from our code or third-party packages, will result in a large JavaScript file. To optimize the bundle it is useful to integrate Terser into our build process. What Terser does is it removes comments, shorten variables names, cut whitespaces and minify our code to make it the shortest possible. Again Terser can be integrated with Rollup using a plugin:
