A vite plugin server and build your.user.js for userscript engine like Tampermonkey and Violentmonkey, Greasemonkey, ScriptCat
- support Tampermonkey, Violentmonkey, Greasemonkey, ScriptCat, etc
- inject userscript comment to build bundle
- auto open *.user.js in default browser when userscript change
- external cdn url inject to userscript @require
- external module inject to userscript @resource
- use GM_api by ESM import with type hints
- intelligently collect GM_api that is used and automatically configure userscript @grant comment
- support
top level awaitanddynamic importin single file - when vite preview, auto open browser install dist.user.js
- full typescript support and vite feature
just like vite create
pnpm create monkey
# npm create monkey
# yarn create monkeythen you can choose the following template
| JavaScript | TypeScript |
|---|---|
| empty (only js) | empty-ts (only ts) |
| vanilla (js + css) | vanilla-ts (ts + css) |
| vue | vue-ts |
| react | react-ts |

});there is the following cdn to use, full detail see cdn.ts
if you want use other cdn, you can see external-scripts
because of the code-rules of greasyfork
Code posted to Greasy Fork must not be obfuscated or minified
so plugin will change the default value of viteConfig.build.minify to false
if you want to enable minify, just set viteConfig.build.minify=true
we can use GM_api by esm module
// main.ts
import { GM_cookie, unsafeWindow, monkeyWindow, GM_addElement } from '$';
// $ is the default alias of vite-plugin-monkey/dist/client
// if you want use 'others', set monkeyConfig.clientAlias='others'
// whatever it is serve or build mode, monkeyWindow is always the window of [UserScript Scope]
console.log(monkeyWindow);
GM_addElement(document.body, 'div', { innerHTML: 'hello' });
// whatever it is serve or build mode, unsafeWindow is always host window
if (unsafeWindow == window) {
console.log('scope->host, host esm scope');
} else {
console.log('scope->monkey, userscript scope');
}

import monkey from 'vite-plugin-monkey';
export default defineConfig({
plugins: [
monkey({

});GM_api will mount to the property of host window/globalThis
// main.ts
console.log(GM_cookie == globalThis.GM_cookie);
console.log({ GM_cookie, unsafeWindow, monkeyWindow, GM_addElement });// vite.config.ts
import { defineConfig } from 'vite';

// auto import example
console.log({ GM_cookie, unsafeWindow, monkeyWindow, GM_addElement });test examples, see /playground
and preact/react/svelte/vanilla/vue/solid examples, see create-monkey
plugin will rebuild your code by generateBundle hook
please ensure that the order of the plugin is the last one
in vite serve mode, the code entry is added as script to target host document.head, code need work between two origins
but the browser will prevent the execution of this script according to the CSP strategy
now just use browser extension Disable-CSP
the variable declared by var from iife-cdn will not become the property of window at monkeyWindow scope, because monkeyWindow scope is not global scope
so if an umd lib is dependent on an iife lib, such as element-plus is dependent on vue, element-plus cdn will not work
detail see issues/5 or greasyfork#1084
the solution is that we append a dataUrl script that will set iife-variable as the property of window after iife-cdn
import { defineConfig } from 'vite';
import monkey, { cdn, util } from 'vite-plugin-monkey';
export default defineConfig(async ({ command, mode }) => ({
plugins: [

'element-plus': cdn.jsdelivr('ElementPlus', 'dist/index.full.min.js'),
},

}));when plugin works with vite legacy, it is necessary to set renderLegacyChunks=false
// vite.config.ts
import legacy from '@vitejs/plugin-legacy';
import { defineConfig } from 'vite';
import monkey from 'vite-plugin-monkey';
export default defineConfig({
plugins: [
legacy({

});If you want to encapsulate GM_api to build a library for others to use
The previous practice generally involved accessing GM_api as a global variable directly in the library code and then referencing and loading it in userscript through @require.
However, this approach does not allow us to manage this dependency through npm or other package managers, and it is not compatible with the usage of ESM GM_api in vite-plugin-monkey.
Now, you only need to import GM_api normally from vite-plugin-monkey/dist/client in your library code. Modify your build config and exclude vite-plugin-monkey/dist/client.
This way, you can build a library that can be used in vite-plugin-monkey. Users of this library only need to install it via npm and use it normally with import.
Of course, if you directly bundle vite-plugin-monkey/dist/client into the build artifact, the library can also be referenced directly through @require.
However, to make the build artifact more concise, it is recommended that you redirect vite-plugin-monkey/dist/client to vite-plugin-monkey/dist/native during the build.
Below is an example using tsup to simultaneously package ESM and IIFE formats. ESM is provided to vite-plugin-monkey users, and IIFE is provided to users who want to reference it through @require.
Additionally, the IIFE format can also be used as a configuration for vite-plugin-monkey's externalGlobals to reduce the size of the build artifact.
// /src/index.ts
import { GM_setValue } from 'vite-plugin-monkey/dist/client';
export const setValue = (name: string, value: unknown) => {
console.log('you invoke setValue', name, value);
GM_setValue(name, value);
};// tsup.config.ts
import { defineConfig } from 'tsup';
const outExtension = (ctx: { format: 'esm' | 'cjs' | 'iife' }) => ({
js: { esm: '.mjs', cjs: '.cjs', iife: '.iife.js' }[ctx.format],
