Usage

Development environment

The development environment is implemented using Connect middleware。

Different from the production environment, you can view the network request record in the Google Chrome console

import { UserConfigExport, ConfigEnv } from 'vite'

import { viteMockServe } from 'vite-plugin-mock'
import vue from '@vitejs/plugin-vue'

export default ({ command }: ConfigEnv): UserConfigExport => {
  return {
    plugins: [
      vue(),
      viteMockServe({
        // default
        mockPath: 'mock',
        enable: true,
      }),
    ],
  }
}
{
    mockPath?: string;
    ignore?: RegExp | ((fileName: string) => boolean);
    watchFiles?: boolean;
    enable?: boolean;
    ignoreFiles?: string[];
    configPath?: string;
}

Options

mockPath

type: string

default: 'mock'

Set the folder where the mock .ts file is stored

If watchFiles:true, the file changes in the folder will be monitored. And synchronize to the request result in real time

If configPath has a value, it is invalid

ignore

type: RegExp | ((fileName: string) => boolean);

default: undefined

When automatically reading analog .ts files, ignore files in the specified format

watchFiles

type: boolean

default: true

Set whether to monitor changes in mock .ts files

enable

type: boolean

default: true

Whether to enable the mock function

configPath

type: string

default: vite.mock.config.ts

Set the data entry that the mock reads. When the file exists and is located in the project root directory, the file will be read and used first. The configuration file returns an array

logger

type: boolean

default: true

Whether to display the request log on the console

Mock file example

/path/mock

// test.ts

import { MockMethod, MockConfig } from 'vite-plugin-mock'
export default [
  {
    url: '/api/get',
    method: 'get',
    response: ({ query }) => {
      return {
        code: 0,
        data: {
          name: 'vben',
        },
      }
    },
  },
  {
    url: '/api/post',
    method: 'post',
    timeout: 2000,
    response: {
      code: 0,
      data: {
        name: 'vben',
      },
    },
  },
  {
    url: '/api/text',
    method: 'post',
    rawResponse: async (req, res) => {
      let reqbody = ''
      await new Promise((resolve) => {
        req.on('data', (chunk) => {
          reqbody += chunk
        })
        req.on('end', () => resolve(undefined))
      })
      res.setHeader('Content-Type', 'text/plain')
      res.statusCode = 200
      res.end(`hello, ${reqbody}`)
    },
  },
] as MockMethod[]

export default function (config: MockConfig) {
  return [
    {
      url: '/api/text',
      method: 'post',
      rawResponse: async (req, res) => {
        let reqbody = ''
        await new Promise((resolve) => {
          req.on('data', (chunk) => {
            reqbody += chunk
          })
          req.on('end', () => resolve(undefined))
        })
        res.setHeader('Content-Type', 'text/plain')
        res.statusCode = 200
        res.end(`hello, ${reqbody}`)
      },
    },
  ]
}

MockMethod

{
  // request url
  url: string;
  // request method
  method?: MethodType;
  // Request time in milliseconds
  timeout?: number;
  // default: 200
  statusCode?:number;
  // response data (JSON)
  response?: ((opt: { [key: string]: string; body: Record<string,any>; query:  Record<string,any>, headers: Record<string, any>; }) => any) | any;
  // response (non-JSON)
  rawResponse?: (req: IncomingMessage, res: ServerResponse) => void;
}

Example (3.0.0 recommended)

Create the mockProdServer.ts file

//  mockProdServer.ts

import { createProdMockServer } from 'vite-plugin-mock/client'

// Import your mock .ts files one by one
// If you use vite.mock.config.ts, just import the file directly
// You can use the import.meta.glob function to import all
import testModule from '../mock/test'

export function setupProdMockServer() {
  createProdMockServer([...testModule])
}
