Once you have a basic TypeScript configuration file (tsconfig.json), please ensure it has the following configuration:
compilerOptions.moduleset to"nodenext"
Since componentize-js (and jco which re-uses it) supports only single JS files,
bundling is necessary, so [rolldown][rolldown] can be used to create a single file bundle.
A Rolldown configuration (rolldown.config.mjs) like the following can be used:
import { defineConfig } from 'rolldown'
export default defineConfig({
input: 'src/component.ts',
external: /wasi:.*/,
output: {
file: 'dist/component.js',
format: 'esm',
},
})
::: info
Feel free to use any other bundlers that you're more comfortable with (rolldown, esbuild, rollup, etc)
