Bright.js

一种更优雅的JavaScript异步流程控制方式。

安装

安装Bright.js命令行工具

npm install -g bright

安装Bright.js模块

npm install bright

在命令行下使用

新建文件 test.bright

var i = 10
for i >= 0 {
  console.log(i)
  sleep 500
  i--
}
console.log('end')

在命令行下执行以下命令

bright test.bright

在Node.js程序中使用

新建文件 test_module.bright

// 模块输出test函数，该函数接收一个参数
let exports.test = function (a) {
  sleep a
  return a
}

新建文件 test.js

// 先载入bright模块，以使用bright的JIT编译器
var bright = require('bright');
// 载入刚才的bright程序
var test_module = require('./test_module');

test_module.test(1000, function (err, ret) {
  // 所有bright里面的函数的最后一个参数为回调函数
  // 回调函数的第一个参数是出错信息，可以在程序中通过throw来返回
  // 第二个参数起为通过return返回的多个值
  if (err) console.log(err && err.stack);
  console.log(ret);
});

在浏览器中使用

1、浏览器环境的JIT编译器

先在HTML页面中加载文件 build/bright.js ，然后在<script type="text/bright"></script>标签内输入bright代码即可。

<script type="text/bright">
var i = 10
for i >= 0 {
  console.log(i)
  sleep 500
  i--
}
console.log('end')
</script>

参考文件 build/test/test_jit.html

2、预编译Bright.js代码，再在浏览器中运行

新建文件 test.bright

var i = 10
for i >= 0 {
  console.log(i)
  sleep 500
  i--
}
console.log('end')

使用Bright.js命令行工具来编译程序

bright -i test.bright -o test.js

先在HTML页面中加载Bright的运行时库 build/bright.runtime.js，然后再载入刚才编译的文件__test.js__即可运行。

参考文件 build/test/test_runtime.html

__Bright.js__命令行工具详细使用说明：bright --help
