Provide local mocks for Vite.
A mock server plugin for Vite, developed based on TypeScript. And support using TypeScript and JavaScript to write Mock API. When the Mock API file is modified, it will be hot updated automatically. Support and compatibility with express.js middlewares.
node version: >=12.0.0
vite version: >=2.0.0
# if using npm
npm i vite-plugin-mock-server -D
# if using yarn
yarn add vite-plugin-mock-server -Dcd ./example
npm install
npm run dev- Config plugin in vite.config.ts, compatible with express.js middlewares.
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import bodyParser from 'body-parser'
import cookieParser from 'cookie-parser'
import mockServer from 'vite-plugin-mock-server'
export default defineConfig({
plugins: [
vue(),
mockServer({
logLevel: 'info',
middlewares: [
cookieParser(),
bodyParser.json(),
bodyParser.urlencoded(),
bodyParser.text(),
bodyParser.raw()
]
})
]
})- Or just use it with the default parameters, place your mocks in the folder "mock" with name that prefix *.mock.ts or *mock.js, The default api to mock is '/api/'
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import mockServer from 'vite-plugin-mock-server'
export default defineConfig({
plugins: [
vue(),
mockServer())
]
})- MockOptions
mockModules Ignore manual configuration, it will be filled in automatically.
export type MockOptions = {
logLevel?: 'info' | 'error' | 'off'
urlPrefixes?: string[]
mockJsSuffix?: string
mockTsSuffix?: string
mockRootDir?: string
mockModules?: string[]
noHandlerResponse404?: boolean
middlewares?: MockLayer[]

}- Request
type Request = Connect.IncomingMessage & {
body?: any,
params?: { [key: string]: string },
query?: { [key: string]: string },
cookies?: { [key: string]: string },
session?: any
}- MockFunction
export type MockFunction = {
(
req: Request,
res: http.ServerResponse,
/** @deprecated in 2.0, use req.params **/
urlVars?: { [key: string]: string }
): void
}- MockHandler
export type MockHandler = {
pattern: string,
method?: string,
handle: MockFunction
}- MockLayer
export type MockLayer = (
req: Request,
res: http.ServerResponse,
next: Connect.NextFunction
) => void;The pattern is an ant-style path pattern string,
use @howiefh/ant-path-matcher
to match the pattern and request URL.
// example/mock/es.mock.ts
import { MockHandler } from '../../src'
const mocks: MockHandler[] = [
{
pattern: '/api/test1/1',
handle: (req, res) => {
res.end('Hello world!' + req.url)
}
},
{
pattern: '/api/test1/*',
handle: (req, res) => {
res.end('Hello world!' + req.url)
}
},
{
pattern: '/api/test1/users/{userId}',
handle: (req, res) => {
const data = {
url: req.url,
params: req.params,
query: req.query,
body: req.body
}
res.setHeader('Content-Type', 'application/json')
res.end(JSON.stringify(data))
}
},
{
pattern: '/api/test1/body/json',
method: 'POST',
handle: (req, res) => {
res.setHeader('Content-Type', 'application/json')
//req is incomingMessage which extends stream.Readable
// --> https://nodejs.org/api/stream.html#readablereadsize
// res.end need to be within the function
// there is a size limit for the bodyString to get parsed
req.on('data', (bodyString: string) => {
let body: object = JSON.parse(bodyString)
res.end(JSON.stringify(body))
})
}
},
]
