Adding type hints to Renovate config.js files I'm a fan of using Renovate's `config.js` file format for the global self-hosting configuration. One thing that's always caught me out, compared to the repo-level configuration, is that I don't get IDE autocomplete by default. Today, I ended up sitting down to look at how to get it working - and turns out it was ~2 lines of code to add 🫣 (This is based on my experience using Neovim 0.11.4, and ts_ls 5.0.1) Because it is "just" a JavaScript file, we can take advantage of JSDoc annotations on our types. With help from GPT-4.1 (via GitHub Copilot), I managed to work out the right syntax to get this working: /** * @typedef {import('renovate/dist/config/types').AllConfig} AllConfig */ /** @type {AllConfig} */ module.exports = { allowedCommands: ['*'], allowedEnv: ['*'], }; This now gives you autocomplete and type hinting when you go to modify `module.exports`, based on Renovate's inbuilt types. Note that you may need to `npm install renovate` in the directory/workspace that you're running from. You can also see it in action in the following Asciicast: https://www.jvt.me/posts/2025/10/21/renovate-configjs-hints/
