前言
Ref: Build Real Web App with React #02 - 20:04 / 34:47
开始介绍后端搭建。
代码分析
一、搭建HTTP服务器
- 安装 bebal
yarn add --dev babel-cli babel-preset-env
配置 package.json ----> 自动执行bebal，when code is changed.
Ref: nodemon 基本配置与使用，使 bebal 自动化。
"scripts": { "start": "nodemon --exec babel-node -- src/index.js" },
- Express http 服务器搭建
(1) index.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Bookworm API</title> </head> <body> <h1>This is API, not a website. Learn your routes, mate!</h1> </body> </html>
要显示的内容。
(2) index.js
import express from "express"; import path from "path"; import mongoose from "mongoose"; import bodyParser from "body-parser"; import dotenv from "dotenv"; import Promise from "bluebird"; import auth from "./routes/auth"; import users from "./routes/users"; import books from "./routes/books"; dotenv.config(); const app = express(); app.use(bodyParser.json());
mongoose.Promise = Promise; mongoose.connect(process.env.MONGODB_URL, { useMongoClient: true }); app.use("/api/auth", auth); app.use("/api/users", users); app.use("/api/books", books); app.get("/*", (req, res) => { res.sendFile(path.join(__dirname, "index.html")); }); app.listen(8080, () => console.log("Running on localhost:8080"));
