Install

# npm
npm i -D vite-plugin-mock-dev-server
# yarn
yarn add vite-plugin-mock-dev-server
# pnpm
pnpm add -D vite-plugin-mock-dev-server

Usage

vite.config.ts

import { defineConfig } from 'vite'
import mockDevServerPlugin from 'vite-plugin-mock-dev-server'

export default defineConfig({
  plugins: [
    mockDevServerPlugin(/* plugin options */),
  ],
  // The fields defined here can also be used in mock.
  define: {},
  server: {
    // plugin will read `server.proxy`
    proxy: {
      '^/api': { target: 'http://example.com' }
    }
  }
})

The plugin will read the configuration of server.proxy or options.prefix, and enable mock matching for matched URLs.

The plugin will also read the define configuration, which supports direct use in mock files.

Edit Mock File

By default, write mock data in the mock directory of your project's root directory:

mock/**/*.mock.ts :

import { defineMock } from 'vite-plugin-mock-dev-server'

export default defineMock({
  url: '/api/test',
  body: { a: 1, b: 2 }
})
