Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

rollup-plugin-violent-monkey

v0.1.1

Published

Prepends ViolentMonkey headers to your rollup bundle

Readme

rollup-plugin-violent-monkey

Disclaimer

rollup-plugin-violent-monkey is actively being developed. The API is rapidly changing and considered unstable. Install or upgrade at your own risk!

Template

Looking for a simple development environment? Have a look at vite-violent-monkey.

Features

  • Pass metadata directly via the options object to the plugin. Works with TypeScript or JavaScript including type completion and validation.
  • Define an external config file via the defineMetadata.
  • Automatically finds grants from all imported modules and includes them in the bundle
  • Importable type declarations for the GM_* & GM.* API supported by ViolentMonkey.

Planned

  • Add @require fields based on code imports, excluding type imports.

Usage

Installation:

# npm
npm i -D rollup-plugin-violent-monkey

# pnpm
pnpm i -D rollup-plugin-violent-monkey

Using Vite:

// vite.cofig.ts
import { defineConfig } from "vite";
import { plugin as violentMonkey } from "rollup-plugin-violent-monkey";

export default defineConfig({
    build: {
        rollupOptions: {
            plugins: [violentMonkey({
                // add your script metadata here
                //...
            })],
        },
    },
});

Using Rollup:

// rollup.config.js
import { plugin as violentMonkey } from "rollup-plugin-violent-monkey";

export default {
    plugins: [violentMonkey({
        // add your script metadata here
        //...
    })],
};

Using a standalone config file

// violentmonkey.metadata.ts or violentmonkey.metadata.js
import { defineMetadata } from "rollup-plugin-violent-monkey";

export default defineMetadata({
  name: "My Violent Script",
  downloadUrl: "github.com/myviolentscriptgist.js",
  grants: ["GM_addElement", "GM.addStyle", "window.focus"],
});

Then import it in your Rollup or Vite config:

// vite.config.ts
import { defineConfig } from "vite";
import { plugin as violentMonkey } from "rollup-plugin-violent-monkey";

import metadata from "./violentmonkey.metadata"

export default defineConfig({
    build: {
        rollupOptions: {
            plugins: [violentMonkey(metadata)],
        },
    },
});
// rollup.config.js
import { plugin as violentMonkey } from "rollup-plugin-violent-monkey";

import metadata from "./violentmonkey.metadata"

export default {
    plugins: [violentMonkey(metadata)],
};

Importing ViolentMonkey type declarations

Create a .d.ts file in the root of your source directory, and add the following:

/// <reference types="rollup-plugin-violent-monkey/context/violentmonkey" />
