A Rollup.js plugin that enables automatic generation of userscript boilerplate from JSON
npm install --save-dev rollup-plugin-userscript-boilerplate
pnpm install --save-dev rollup-plugin-userscript-boilerplate
yarn add --dev rollup-plugin-userscript-boilerplate
Create a rollup.config.mjs configuration file and import the plugin:
import boilerplate from 'rollup-plugin-userscript-boilerplate'; export default { input: 'src/index.js', output: { dir: 'output', format: 'iife' }, plugins: [ boilerplate({ // Metadata path metadata: "src/metadata.json", // Your source script (like iife format) source: "src/index.js", // Output path output: "output/dev.user.js" }) ] };
Create a metadata.json metadata file like this:
{
"name": "my-plugin",
"version": "1.0.0",
"match": [
"https://example.com/",
"https://example.net/"
]
}It will generate the boilerplate to your path.
