typewritingclass-esbuild

esbuild plugin for Typewriting Class static CSS extraction.

Installation

bun add -d typewritingclass-esbuild

Requires esbuild >= 0.17.0 as a peer dependency.

Usage

import esbuild from 'esbuild'
import twcPlugin from 'typewritingclass-esbuild'

await esbuild.build({
  entryPoints: ['src/main.ts'],
  bundle: true,
  plugins: [twcPlugin()],
})

Import the virtual CSS module in your source:

import 'virtual:twc.css'

Options

twcPlugin({
  strict: true,  // Error on unwrapped dynamic values (default: true)
})

How it works

The plugin uses a three-phase pipeline:

1. onResolve — intercepts virtual:twc.css imports
2. onLoad (transform) — passes TS/JS files through the Rust compiler
3. onLoad (virtual CSS) — aggregates all extracted rules into the virtual CSS module
