A (primarily) zero-config bundler for HTML files. The idea is to use HTML as Single File Components, because HTML can already include <style> and <script> elements.
- 🦾 TypeScript (reference it as .js or write inline TS)
- 📦 Automatic Package Installation
- 💨 HMR and automatic reconnect
- ⚡ ESBuild
- 🦔 Critical CSS
- 🚋 Watcher on PostCSS and Tailwind CSS and TS Config
- 🛡️ Almost no need to restart
$ npm install -D html-bundleAdd an entry to script in package.json (see flags below).
{
"scripts": {
"build": "html-bundle"
}
}Add a postcss.config.js file and run the build command.
If you do not create this config file, a minimal in-memory config file will be created with cssnano as plugin.
$ npm run build--hmr: boots up a static server and enables Hot Module Replacement. This generates a development build and works best when not triggered from the main index.html
--secure: creates a secure HTTP2 over HTTPS instance. This requires the files localhost.pem and localhost-key.pem in the root folder. You can generate them with mkcert for instance.
--isCritical: uses critical to extract and inline critical-path CSS to HTML.
--handler: path to your custom handler. Here, you can handle all non-supported files. You can get the filename via process.argv[2].
The CLI flags can also be set by the config. Flags set by the CLI will override the config. Generate the config in the root and call it "bundle.config.js"
src: input path. Default to "src"
build: output path. Defaults to "build"
port: For the HMR Server. Defaults to 5000
deletePrev: Whether to delelte the build folder. Defaults to true
esbuild: Your additional config
html-minifier-terser: Your additional config
critical: Your additional config
Example:
/** @type {import('html-bundle').Config} */
export default {
secure: true,
handler: "utils/staticFiles.js",
esbuild: {
external: ["images"],
},
};The bundler always globs all HTML, CSS and TS/JS files from the src (config) directory and processes them to the build (config) directory. PostCSS is being used for CSS files and inline styles, html-minifier-terser for HTML and esbuild to bundle, minify, etc. for inline and referenced TS/JS. Server-sent events and hydro-js are used for HMR. In order to trigger SPA Routers, the popstate event is being triggered after HMR Operations.
