logoran-run

执行logoran用到async的时候需要babel环境，这里稍微简单的封装了一下，以便于更简单的使用logoran的时候，不用在意babel的细节

它是logoran-generator的核心组件

• 暂时不支持Windows

依赖

• "babel-core": "^6.7.5",
• "babel-polyfill": "^6.1.4",
• "babel-preset-es2015-node": "^6.1.4",
• "babel-preset-stage-3": "^6.5.0",
• "babel-plugin-add-module-exports": "^0.1.2",

Features

• if use node v7.x，logoran-run is an alias with node --harmony-async-await
• 不需要了解babel即可使用logoran+async组合
• 对logoran项目代码无入侵，启动时入口处理而已
• 支持logoran里的3种异步调用方式，无需其他，完美支持
• 支持cli命令，即logoran-run执行
• 默认读取bin/www文件，启动logoran服务
• 遵循小而美

Install

npm i -g logoran-run

Usages

logoran-run app.js

Code Example

require('logoran-run')(__dirname + '/app.js' )

Test

logoran支持3种写法，分别测试如下

Logoran is an middleware framework, it can take 3 different kind function as middleware:

• common function
• async function
• generatorFunction

Here we write an logger middleware with different function.

logoran-run app.js
logoran-run app-async.js     
logoran-run app-generator.js 

集成supervisor或nodemon

代码变动，使用supervisor或nodemon自动重启服务是开发里比较好的实践，logoran-run可以非常好的和它们进行集成，让开发更简单

首先通过logoran-run来加载bin/www里,代码如下

require('logoran-run')(__dirname + '/app.js')

然后执行

nodemon bin/www

此时，你可以放心的去修改你的代码了

集成pm2

touch bin/run

var current_path = process.cwd();

require('logoran-run')(current_path + '/bin/www' )

然后执行pm2即可

 #npm run pm2
 pm2 start bin/run 

FAQ

重复引用require("babel-polyfill")可能出现的问题

➜  logoran-demo logoran-run index.js 
index.js
/Users/sang/workspace/logoran/demo/node_modules/babel-polyfill/lib/index.js:14
  throw new Error("only one instance of babel-polyfill is allowed");
  ^

Error: only one instance of babel-polyfill is allowed
    at Object.<anonymous> (/Users/sang/workspace/logoran/demo/node_modules/babel-polyfill/lib/index.js:14:9)

    at require (module.js:384:17)
    at Object.<anonymous> (index.js:3:1)
    at Module._compile (module.js:434:26)
➜  logoran-demo cat index.js 
'use strict';
   
require("babel-polyfill");

// set babel in entry file
require('babel-core/register')({
  presets: ['es2015-node5', 'stage-3']
});

require('./app'); // this is es7 - gets transpiled

这时正确的操作是

logoran-run  app.js

如果本地已安装logoran-run的依赖，会报错

依赖

• "babel-core": "^6.7.5",
• "babel-polyfill": "^6.1.4",
• "babel-preset-es2015-node": "^6.1.4",
• "babel-preset-stage-3": "^6.5.0"

请保持你的package.json或node_modules目录下无这些依赖即可

这是因为logoran-run需要指定babel需要的preset地址
