koa2 uses ES7 syntax, such as async and await, so it needs to be run after node7.6; but before node7.6, you can also use koa2, which is the babel, to run.
First, install babel and several modules of babel in the project:
npm install babel babel-register babel-preset-env --save
Then introduce the 'babel-register' module in the entry file
require('babel-register');
Then introduce the business code:
require('./');
In the configuration .babelrc file:
{
"presets": [
["env", {
"targets": {
"node": true
}
}]
]
}
Example:
:
require('babel-register');
require('./servers/devserver');
:
var koa = require('koa');
var app = new koa();
const request = require('request');
let port = || 8080;
("set port:" + + "; ip:" + );
(async (ctx) => {
();
if (('/aaa') > -1) {
('content-type', 'text/javascript');
= ('http://127.0.0.1/', function(err, response, body) {
(body);
});
}
});
(port);
