如何运行启用ES6功能的Node.js应用程序? [英] How to run Node.js app with ES6 features enabled?
问题描述
我使用 BabelJS的需要钩子 (以前称为6to5)以 es6features 运行节点应用程序:
// run.js
require(babel / register);
require(./ app.js6);
我调用节点run.js
运行我的 app.js6 。我需要安装BabelJS,并为每个我想使用es6features的项目提供一个 run.js 。我更喜欢像 nodejs6 app.js6
这样的电话。如何独立实现这个系统(Unix和Windows)?
添加 babel-cli
和 babel-preset-es2015
(又称ES6)依赖于您的应用程序的package.json文件并定义一个开始
脚本:
{
dependencies:{
babel-cli ^ 6.0.0,
babel-preset-es2015:^ 6.0.0
},
scripts:{
start:babel -node --presets es2015 app.js
}
}
然后您可以简单地执行以下命令来运行您的应用程序:
npm start
/ pre>
如果您决定停止使用Babel(例如,一旦Node.js支持所有ES6功能),您可以从package.json中删除它:
{
dependencies:{},
scripts:{
start node app.js
}
}
其中一个好处是那个c ommand运行您的应用程序保持不变,这有助于您与其他开发人员合作。
I use the require hook of BabelJS (formerly named 6to5) to run node apps with es6features:
// run.js require("babel/register"); require("./app.js6");
I call
node run.js
to run my app.js6. I need to install BabelJS and provide a run.js for each project I'd like to use es6features. I would prefer a call likenodejs6 app.js6
. How can I achieve this system independently (Unix and Windows)?解决方案Add the
babel-cli
andbabel-preset-es2015
(aka ES6) dependencies to your app's package.json file and define astart
script:{ "dependencies": { "babel-cli": "^6.0.0", "babel-preset-es2015": "^6.0.0" }, "scripts": { "start": "babel-node --presets es2015 app.js" } }
Then you can simply execute the following command to run your app:
npm start
If you ever decide to stop using Babel (e.g. once Node.js supports all ES6 features), you can just remove it from package.json:
{ "dependencies": {}, "scripts": { "start": "node app.js" } }
One benefit of this is that the command to run your app remains the same, which helps if you are working with other developers.
