Twitch Drops Manager

dev

1. Allow Tampermonkey access to local file URIs tampermonkey/faq
2. install deps with npm i or npm ci.
3. npm run dev to start your development. Now you will see 2 files in ./dist/
   • dist/index.dev.user.js: **You should install this userscript in your browser. ** It's a simple loader that load dist/index.debug.js on matched web page.
   • dist/index.debug.js: This is the development build with eval-source-map. It will be automatically loaded by dist/index.dev.user.js via @require file://.../dist/index.debug.js metadata, Don't add it to your userscript manager.
4. edit src/index.ts, you can even import css or less files. You can use scss if you like.
5. go to https://twitch.com/ and open the console, you'll see it's working.

livereload is enabled by default, use this Chrome extension

NOTICE

Everytime you change your metadata config, you'll have to restart webpack server and install the newly generated dist/index.dev.user.js UserScript in your browser again.

Cross Site Request

You can call GM.xmlHttpRequest directly or use a fetch API based on GM.xmlHttpRequest https://github.com/Trim21/gm-fetch

TypeScript

Use typescript as normal, see src/index.ts

dependencies

There are two ways to using a package on npm.

UserScript way

like the original UserScript way, you will need to add them to your user script metadata's require section , and exclude them in config/webpack.config.base.cjs

Webpack way

Just install packages with npm and import them in your code, webpack will take care them.

Build

npm run build

dist/index.prod.user.js is the final script. you can manually copy it to greasyfork for deploy.

Minify

There is a limitation in greasyfork, your code must not be obfuscated or minified.

If you don't need to deploy your script to greasyfork, enable minify as you like.

automatically Deploy

GitHub Actions will deploy production userscript to gh-pages branch.

example

deployed

You can auto use greasyfork's auto update function.

Q&A

You may find enabling source map not working well in production code, because Tampermonkey will add extra lines (all your @require) before your script. I don't know if there is a good fix for this, You need to use webpack config devtool with eval prefix to make it work as expected, so source map is disabled in this template.
