Discord Detours

Discord Detours is a package that helps you find, call, and hook into Discord client's functions.
This is intended to be used with tools like Puppeteer which let you programmatically control a browser instance and run JavaScript code in its context. You can also inject api.js into Discord using an extension like Inject Code directly from your browser.

Installation

npm install @gilgames/discord-detours

API reference

Utility functions for injecting the code (to be used with Puppeteer)

• detours.serializeModule(module): serializes a module into a string (JSON.stringify is no good as it won't serialize functions)
• detours.injectModule(serializedModule[, name]): injects a serialized module into window.name (namedefaults to discordDetours if not specified)

APIs for finding functions and modules

• detours.api.getAllModules(): returns a list of all modules
• detours.api.findModuleByFunctionName(name): returns a module by function name
• detours.api.findFunctionByName(name): returns a function by name
• detours.api.findFunctionsMatchingPattern(pattern): returns a list of functions matching a regex pattern

APIs for hooking/detouring functions

Will be added in the future.

Usage

Puppeteer

const detours = require("@gilgames/discord-detours");

// Open the browser with Puppeteer, navigate to Discord, and login
// ...

// Execute the code in the browser's context using Puppeteer's `page.evaluate`
const serializedAPI = detours.serializeModule(detours.api);
await page.evaluate(detours.injectModule, serializedAPI);

// Call any Discord function
const token = await page.evaluate(() => window.discordDetours.findFunctionByName("getToken")());
console.log(token);

Using your browser

First you have to install an extension that lets you inject code into a webpage. Then, navigate to Discord's website, login, and inject the code that you can find in the api.js file, bar the module export at the bottom. You can now call the API functions described in the usage section directly from the console of your browser.
