rollup-plugin-add-userscript-header

A rollup plugin that adds a userscript header to a .js file.

Tags

Added from `package.json` file

By default, the plugin uses the following fields from the projects package.json file and adds tags accordingly:

`package.json` field	tag
name	@name
version	@version
author	@author
description	@description
license	@license (unoffical tag)
homepage	@homepage

@downloadURL & @updateURL

These tags get populated via the repository field combined with the main field.

The url is contructed like this: <repo>/release/latest/download/<main>

@grant

@grant directives do not need to be added manually.

The plugin checks the given code for occurrences and adds them automatically. This includes the following:

GM.* & GM_* calls
unsafeWindow
window.close
window.focus
window.onurlchange

Other tags

You can specify more tags in package.json by adding a userscriptMetadata field.

Alternatively, you can pass them to the plugin directly through the rollup.config.js / rollup.config.ts file.

Options

The only option to set is the meta option. It contains all the tags you want to set.

See the below for some examples!
