# js example

cd ./examples/js-examples

yarn install

yarn serve

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

  • Config plugin in vite.config.ts
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',
        localEnabled: command === 'serve',
      }),
    ],
  }
}
{
    mockPath?: string;
    supportTs?: boolean;
    ignore?: RegExp | ((fileName: string) => boolean);
    watchFiles?: boolean;
    localEnabled?: boolean;
    ignoreFiles?: string[];
    configPath?: string;
    prodEnabled?: boolean;
    injectFile?: string;
    injectCode?: 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

supportTs

type: boolean

default: true

After opening, the ts file module can be read. Note that you will not be able to monitor .js files after opening.

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

localEnabled

type: boolean

default: command === 'serve'

Set whether to enable the local mock .ts file, do not open it in the production environment

prodEnabled

type: boolean

default: command !=='serve'

Set whether to enable mock function for packaging

injectCode

type: string

default:

If the mock function is enabled in the production environment, that is, prodEnabled=true, the code will be injected into the bottom of the file corresponding to injectFile. The default is main.{ts,js}

The advantage of this is that you can dynamically control whether mock is enabled in the production environment and mock.js will not be packaged when it is not enabled.

If the code is written directly in main.ts, no matter whether it is turned on or not, the final package will include mock.js

injectFile

type: string

default: path.resolve(process.cwd(),'src/main.{ts,js}')

The file injected by injectCode code, the default is src/main.{ts,js} in the project root directory

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 } 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[]

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 (2.0.0 recommended)

Create the mockProdServer.ts file

//  mockProdServer.ts

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

// 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])
}

Config vite-plugin-mock

import { viteMockServe } from 'vite-plugin-mock'

import { UserConfigExport, ConfigEnv } from 'vite'

export default ({ command }: ConfigEnv): UserConfigExport => {
  // According to the project configuration. Can be configured in the .env file
  let prodMock = true
  return {
    plugins: [
      viteMockServe({
        mockPath: 'mock',
        localEnabled: command === 'serve',
        prodEnabled: command !== 'serve' && prodMock,
        injectCode: `
          import { setupProdMockServer } from './mockProdServer';
          setupProdMockServer();
        `,
      }),
    ],
  }
}
