webpack-api-mocker 是一个为 REST API 建立 mock 的 webpack-dev-server 中心件。 当您尝试在没有现实的 REST API 服务器的情况下,测试您的应用程序时,这将会很有协助。
装置
npm install webpack-api-mocker --save-dev
运用
定义API,假定我们讲API放到一个自力文件 mocker/index.js
中, 下面我们定义四个 API
,每一个 API
都放到 json
的 key
和 value
中,以下:
const proxy = {
'GET /api/user': {id: 1, username: 'kenny', sex: 6 },
'GET /api/user/list': [
{id: 1, username: 'kenny', sex: 6 },
{id: 2, username: 'kenny', sex: 6 }
],
'POST /api/login/account': (req, res) => {
const { password, username } = req.body;
if (password === '888888' && username === 'admin') {
return res.send({
status: 'ok',
code: 0,
token: "sdfsdfsdfdsf",
data: {id: 1, username: 'kenny', sex: 6 }
});
} else {
return res.send({status: 'error', code: 403 });
}
},
'DELETE /api/user/:id': (req, res) => {
console.log('---->', req.body)
console.log('---->', req.params.id)
res.send({ status: 'ok', message: '删除胜利!' });
}
}
module.exports = proxy;
上面的 key
比较特别,由 methd
和 path
组合,中心一个空格距离,如:GET /api/user
。value
可所以 json
或许 函数
。
在 Webpack 中运用
要在你的 Webpack
项目中运用 api mocker
,只需将设置选项,增加到你的 webpack-dev-server 选项中即可:
转变你的配置文件,通知dev服务器在那里查找文件:webpack.config.js。
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
+ const apiMocker = require('webpack-api-mocker');
module.exports = {
entry: {
app: './src/index.js',
print: './src/print.js'
},
devtool: 'inline-source-map',
+ devServer: {
+ ...
+ before(app){
+ apiMocker(app, path.resolve('./mocker/index.js'), {
+ proxy: {
+ '/repos/*': 'https://api.github.com/',
+ },
+ changeHost: true,
+ })
+ }
+ },
plugins: [
new HtmlWebpackPlugin({
title: 'Development'
})
],
output: {
filename: '[name].bundle.js',
path: path.resolve(__dirname, 'dist')
}
};
模仿API代办变得简朴。
{
before(app){
+ apiMocker(app, path.resolve('./mocker/index.js'), {
+ proxy: {
+ '/repos/*': 'https://api.github.com/',
+ },
+ changeHost: true,
+ })
}
}
让我们增加一个脚原本轻松运转开辟服务器:
修正 package.json
{
"name": "development",
"version": "1.0.0",
"description": "",
"main": "webpack.config.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"watch": "webpack --progress --watch",
+ "start": "webpack-dev-server --open",
"build": "webpack"
},
"keywords": [],
"author": "",
"license": "ISC",
"devDependencies": {
"clean-webpack-plugin": "^0.1.16",
"css-loader": "^0.28.4",
"csv-loader": "^2.1.1",
"file-loader": "^0.11.2",
"html-webpack-plugin": "^2.29.0",
"style-loader": "^0.18.2",
"webpack": "^3.0.0",
"xml-loader": "^1.2.1"
}
}
运转下面敕令,跑起来,经由过程东西测试一下你模仿的API是否能返回效果。
npm run start
Express 中运用
const path = require('path');
const express = require('express');
+ const apiMocker = require('webpack-api-mocker');
const app = express();
+ apiMocker(app, path.resolve('./mocker/index.js'))
app.listen(8080);
