Minify md icons and font in your app.
Generates fonts with only the symbols you use in your app ✨
npm add -D rollup-plugin-md-icon
Do not use anything ! Just add this stylesheet in the header of your html document:
<head> <link id="symbols" href="https://fonts.googleapis.com/icon?family=Material+Symbols+Outlined" rel="stylesheet" /> </head>
This stylesheet serves a font that contains all symbols from fonts.googleapis.com (learn more)
We'll need to convert the link above.
From here you can opt one of 2 strategies:
1️⃣ Serve minified font file from fonts.googleapis.com : See instructions on the wiki.
It's the easiest option. The plugin will update the href in the final html to request a stylesheet that will load a font file that contains only the icons your app needs (That will count for 2 http requests).
2️⃣ Serve font file locally : See instructions on the wiki.
Less intuitive to implement but recommended. The plugin will download the stylesheet and the minified font so you have more control on how you serve them (e.g. bundling the stylesheet directly in a module, caching the font in a service worker, etc..)
The monorepo of this plugin can be found here
The plugin scans the source code to build a list of all used icons called a codepoints list which is saved under the cache directory .mdicon. The cache system is used to avoid downloading the fonts every time rollup runs (which can happen a lot during development). The cached codepoints list is used to generate minimal final font files or urls depending on which strategy you use at build time.
include) which means the final font could potentially includes icons that are or will not be used at runtime if some files are being excluded from the module graph at build time.MIT
