      sourceFilesGlob: "src/**/*.ts", // Optional
      entryFile: "src/index.ts", // Optional
      typeAliasName: "App", // Optional
    },
  ],

Options

GenerateDocsOptions

• apps: Array of AppConfig objects defining the apps to document.
• projectRoot: Path to the project root.
• tsConfigFilePath: Path to the TypeScript config file (default: "{projectRoot}/tsconfig.json").
• outputPath: Output file path (default: "DOCS.md").
• title: Document title (default: "API Documentation").
• description: Document description (default: "This document contains API documentation for the configured apps.").

AppConfig

• name: Display name for the app.
• sourceFilesGlob: Glob pattern for source files (optional).
• entryFile: Path to the entry file containing the type alias.
• typeAliasName: Name of the type alias defining the routes (default: "App").

Requirements

• Your Elysia app must export a type alias (e.g., export type App = ...) that defines the route structure.
• The project must have a tsconfig.json file.

Example

For an Elysia app like:

import { Elysia } from "elysia";

const app = new Elysia()
  .get("/hello", () => "Hello World")
  .post("/users", ({ body }) => createUser(body), {
    body: t.Object({ name: string }),
  });

export type App = typeof app;

The generator will create documentation with SDK usage examples, request/response types, etc.
