require（'babel / register'）不起作用 [英] require('babel/register') doesn't work

问题描述

我在ES6上用 Babel transpiler 在客户端上编写了同构的应用程序。我希望我的快递服务器具有与客户端代码相同的ES6语法。

不幸的是， require（'babel / register'）不工作..

server.js

  require（'babel / register'）; //不工作
 // require（'babel-core / register）;不工作.. 
 
 const env = process.env.NODE_ENV || 发展; 
 const port = process.env.NODE_PORT || 1995; 
 
 const http = require（'http'）; 
 const express = require（'express'）; 
 const address = require（'network-address'）; 
 
 let app = express（）; 
 
 app.set（'port'，port）; 
 app.use（express.static（path.join（__ dirname，'public'）））; 
 
 app.get（'*'，（req，res）=> {
 res.send（'Hello！'）; 
}）; 
 
 http.createServer（app）.listen（app.get（'port'），function（）{
 console.info（'Demo app is listening on'％s：％s env =％s'，address（），app.get（'port'），env）; 
}）; 
  

解决方案

require（'babel /注册'）不会调用它所调用的文件。如果您希望将server.js包含在即时转换中，则应该使用 babel-node （Babel的节点的.io / docs / usage / cli /rel =nofollow noreferrer> CLI替换。

查看我的答案这里为例。

I have isomorphic app written in ES6 on client with Babel transpiler. I want my express server to have the same ES6 syntax as client code.

Unfortunately require('babel/register') doesn't work..

server.js

require('babel/register'); // doesn't work
// require('babel-core/register); doesn't work..

const env = process.env.NODE_ENV || 'development';
const port = process.env.NODE_PORT || 1995;

const http = require('http');
const express = require('express');
const address = require('network-address');

let app = express();

app.set('port', port);
app.use(express.static(path.join(__dirname, 'public')));

app.get('*', (req, res) => {
   res.send('Hello!');
});

http.createServer(app).listen(app.get('port'), function () {
   console.info('Demo app is listening on "%s:%s" env="%s"', address(), app.get('port'), env);
});

解决方案

require('babel/register') doesn't transpile the file it is called from. If you want server.js to be included in on-the-fly transpilation, you should execute it with babel-node (Babel's CLI replacement for node).
