Adding HTTP Endpoints

When to Use

• Creating a new HTTP route
• Adding an API endpoint
• Wiring a new handler to the Hono app

Route File Pattern

Each endpoint gets its own file with colocated schema, types, and handler.

Location: src/server/routes/{category}/{endpoint}.ts

// src/server/routes/auth/login.ts

import { z } from 'zod';
import type { Context } from 'hono';
import type { ISessionManager } from '../types';

// 1. Request schema (colocated)
export const loginRequestSchema = z.object({
    url: z.string().url(),
    client: z.string().min(1).max(3),
    auth: authConfigSchema
});

// 2. Response type (colocated)
export interface LoginResponse {
    sessionId: string;
    username: string;
    expiresAt: number;
}

// 3. Single handler export (factory pattern)
export function loginHandler(sessionManager: ISessionManager) {
    return async (c: Context) => {
        const body = await c.req.json();
        const validation = loginRequestSchema.safeParse(body);

        if (!validation.success) {
            return c.json({
                success: false as const,
                error: 'Invalid request',
                code: 'VALIDATION_ERROR'
            }, 400);
        }

        // ... implementation ...

        return c.json({ success: true as const, data: response });
    };
}

Wiring Routes

Register routes in src/server/routes/index.ts:

import { loginHandler } from './auth/login';

export function registerRoutes(app: Hono, sessionManager: ISessionManager) {
    // Auth routes
    app.post('/login', loginHandler(sessionManager));

    // Add your new route here
}

Response Format

All endpoints use a consistent envelope:

// Success
return c.json({ success: true as const, data: result });

// Error
return c.json({
    success: false as const,
    error: 'Human-readable message',
    code: 'MACHINE_CODE'
}, statusCode);

Use as const for literal types in discriminated unions.

Library Mode Mapping

If the endpoint wraps core functionality, add a method to ADTClient:

| HTTP Endpoint | Library Method | |--------------|----------------| | POST /login | client.login() | | GET /packages | client.getPackages() | | POST /objects/read | client.read(objects) |

Documentation Requirements

Create endpoint docs in docs/endpoints/{category}.md.

Required structure:

1. Title and description
2. ## Sections TOC with anchor links
3. Per-endpoint:
   • Description paragraph
   • Request table (Method, Path, Auth Required)
   • Request Body table (Field, Type, Required, Description)
   • Response table (Field, Type, Description)
   • Example request/response JSON
   • Error codes table
   • Use cases list
   • Library Usage section

See docs/endpoints/auth.md for a complete example.
