To generate API documentation for a Koa-based server, you can use tools like Swagger or APIDoc. Here is a step-by-step guide using Swagger:
- Install Swagger: npm install swagger-jsdoc swagger-ui-express
- Create a file named swagger.js in the root directory and add the following code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 |
const swaggerJsdoc = require('swagger-jsdoc');
const swaggerUi = require('swagger-ui-express');
const Koa = require('koa');
const app = new Koa();
// Swagger options
const options = {
definition: {
openapi: '3.0.0',
info: {
title: 'Your API',
version: '1.0.0',
description: 'API documentation using Swagger',
},
},
// Path to the API docs
apis: ['./routes/*.js'], // Update with your route files path
};
const specs = swaggerJsdoc(options);
app.use('/api-docs', swaggerUi.serve);
app.get('/api-docs', swaggerUi.setup(specs));
// Rest of your server code
app.listen(3000, () => {
console.log('Server is running on port 3000');
});
|
- In your route files, add Swagger annotations to document the APIs. For example, in a file named userRoutes.js:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
/**
* @swagger
* /users:
* get:
* summary: Get all users
* responses:
* 200:
* description: OK
*/
router.get('/users', async (ctx) => {
// Your code here
});
// Add more routes with Swagger annotations
|
- Start your Koa server: node swagger.js
- Access the API documentation at http://localhost:3000/api-docs. Swagger UI will display the API endpoints, request/response details, and more.
Make sure to update the file paths and modify the Swagger options as per your application's needs.
