服务器.js

const mongoose = require('mongoose');
const bodyParser = require('body-parser');
const users = require('./routes/api/users');
const profile = require('./routes/api/profile');
const posts = require('./routes/api/posts');
const app = express();
// Body parser 
middlewareapp.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
// // DB Config
const db = require('./config/keys').mongoURI;
// Connect to MongoDB
mongoose
    .connect(db)
    .then(() => console.log('MongoDB Connected'))
.catch(err => console.log(err));
app.get('/', (req, res)=> res.send('Hello World!'));
// Use Routes
app.use('/api/users', users);
app.use('/api/profile', profile);
app.use('/api/posts', posts);
const port = process.env.PORT || 5001;
app.listen(port, () => console.log(`Server running on port ${port}`));
