复习node中加载静态资源--用express+esj

不做解释，代码一看就懂

app.js

import express from 'express'
import config from './config'
const app = express()
app.use('/node_modules', express.static(config.node_modules_path))
app.use('/public', express.static(config.public_path))
app.set('views', config.viewPath)
app.set('view engine', 'ejs')
app.get('/', (req, res) => {
  res.render('index')
})
app.listen(3000, () => {
  console.log('server is running at port 3000...')
})

config.js

import { join } from 'path'
export default {
  viewPath: join(__dirname, '../views'),
  node_modules_path: join(__dirname, '../node_modules'),
  public_path: join(__dirname, '../public')
}
