plugins VS node

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.

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:

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:

// 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, },

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.

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 } };`

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.

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.

import svelte from 'rollup-plugin-svelte'; import commonjs from '@rollup/plugin-commonjs'; import resolve from '@rollup/plugin-node-resolve'; import livereload from 'rollup-plugin-livereload'; import { terser } from 'rollup-plugin-terser'; import css from 'rollup-plugin-css-only'; import sveltePreprocess from 'svelte-preprocess'; const production = !process.env.ROLLUP_WATCH; function serve() { let server; function toExit() { if (server) server.kill(0); } return { writeBundle() { if (server) return; server = require('child_process').spawn( 'npm', ['run', 'start', '--', '--dev'], { stdio: ['ignore', 'inherit', 'inherit'], shell: true, } ); process.on('SIGTERM', toExit); process.on('exit', toExit); }, }; } export default { input: 'src/main.js', output: { sourcemap: true, format: 'iife', name: 'app', file: 'public/build/bundle.js', }, plugins: [ svelte({ preprocess: sveltePreprocess({ sourceMap: !production, postcss: { plugins: [require('tailwindcss'), require('autoprefixer')], }, }), 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, }, };

You should have Nodejs installed on your laptop and if not, check the Node.js official website, and download/ install the latest and stable release.

Node.js

To install and run Ember.js, you'll need to follow these steps: Install Node.js and npm (Node Package Manager) on your computer. You can download the latest version of Node.js from the official website. Once Node.js and npm are installed, open a terminal window and run the following command to install the Ember.js command line interface (CLI):

NodeJS - Link

To get involved in the Node.js developer community, you can join community discussions or begin with learning if you’re new. The community discussion houses a GitHub list of issues related to Node.js' core features. If you want to chat in real time about Node.js development, there are Slack groups, and you can still connect with IRC clients or web clients when using the browser. Node.js has a calendar for public meetings.

Download the latest version from the Node.js website, open the package installer, and follow the instructions Use a package manager like Homebrew with the command brew install node On Linux, you can consult this page to determine how you should install Node.

As with all experimental things, a few things are missing. Some of these might lead to people using dotenv until support for these gets added. I will mention them here and let you see if they are dealbreakers. You can also follow the GitHub issue to track missing feature support.
