This is Vite 1.x – 6.x LEGACY documentation archive / 这是 Vite 1.x – 6.x 旧版文档归档

• These pages correspond to old plugin releases: vite-plugin-view ≤ 4.x, vite-plugin-external ≤ 7.x, vite-plugin-build-chunk ≤ 4.x, etc.
• Bundler covered: Rollup + esbuild (the default Vite 6 and below stack). This does NOT apply to Vite 8+ with the new Rolldown bundler; Vite 7/8+ users, go to the current docs immediately.

Usage Examples (legacy)

Specify the directory to add mock routes to the dev server

vite.config.mjs

import { defineConfig } from 'vite';
import mockData from 'vite-plugin-mock-data';

export default defineConfig({
  plugins: [
    mockData({
      routes: './mock'
    })
  ]
});

Make a mock route file mock/test.ts

.
├── mock
│   └── test.ts

The mock route file:

module.exports = {
  '/hello': 'hello',
  '/hello2'(req, res) {
    res.statusCode = 200;
    res.setHeader('Content-Type', 'text/html');
    res.end('hello2');
  },
  '/hello3': {
    handler(req, res) {
      res.statusCode = 200;
      res.setHeader('Content-Type', 'text/html');
      res.end('hello3');
    }
  },
  '/json': {
    handler: { hello: 1 }
  },
  '/package.json': {
    file: './package.json'
  }
};

Make a request to /package.json from the browser

fetch('/package.json')
  .then(res => res.json())
  .then((json) => {
    console.log(json);
  });

add mock routes to the dev server

vite.config.mjs

import { defineConfig } from 'vite';
import mockData from 'vite-plugin-mock-data';

export default defineConfig({
  plugins: [
    mockData({
      routes: {
        '/hello': 'hello',
        '/hello2'(req, res) {
          res.statusCode = 200;
          res.setHeader('Content-Type', 'text/html');
          res.end('hello2');
        },
        '/hello3': {
          handler(req, res) {
            res.statusCode = 200;
            res.setHeader('Content-Type', 'text/html');
            res.end('hello3');
          }
        },
        '/json': {
          handler: { hello: 1 }
        },
        '/package.json': {
          file: './package.json'
        }
      }
    })
  ]
});

fetch('/package.json')
  .then(res => res.json())
  .then((json) => {
    console.log(json);
  });
