Easier Express With Async/Await
Plain, old Express
// server.js
var express = require('express')
var app = module.exports = express()
require('./routes')
app.listen(3000)// routes.js
var app = require('./app')
app.get('/user/:id', function (req, res) {
})// routes.js
var app = require('./app')
app.get('/user/:id', function (req, res) {
db.findById(req.params.id)
})// routes.js
var app = require('./app')
app.get('/user/:id', function (req, res) {
db.findById(req.params.id).then(function (err, user) {
})
})// routes.js
var app = require('./app')
app.get('/user/:id', function (req, res) {
db.findById(req.params.id).then(function (err, user) {
if (err) {
res.status(404).send('User not found')
return
}
})
})// routes.js
var app = require('./app')
app.get('/user/:id', function (req, res) {
db.findById(req.params.id).then(function (err, user) {
if (err) {
res.status(404).send('User not found')
return
}
res.json(user)
})
})Adding Babel
require('babel/register')
require('babel/register')({ stage: 1 })
Express On Babel
// server.js
require('babel/register')({ stage: 1 })
var express = require('express')
var app = module.exports = express()
require('./routes')
app.listen(3000)// routes.js
var app = require('./app')
app.get('/user/:id', async function (req, res) {
try {
res.json(await db.findById(req.params.id))
} catch (err) {
res.status(404).send('User not found')
}
})// server.js
var express = require('express')
var app = module.exports = express()
require('./routes')
app.listen(3000)// routes.js
var app = require('./app')
app.get('/user/:id', function (req, res) {
db.findById(req.params.id).then(function (err, user) {
if (err) {
res.status(404).send('User not found')
return
}
res.json(user)
})
