#babel-plugin-conditional-compile Evaluate If statement and remove unavailable code
Conditional Compile
You may rewrite code like
if(IS_DEV){
console.log('track infomation')
}
var foo;
if(CODE_FOR_IE){
foo=1;
}
else if(CODE_FOR_CHROME){
foo=2;
}
But you don't want to log until it is published and if you know the code target,you can just kick the redundant when published. The code to publish for chrome will be like.
var foo;
foo=2;
Installation
$ npm install babel-plugin-conditional-compile-v2 --save-dev
Usage
Via Node API
require("babel-core").transform("code", {
plugins: ["conditional-compile",{
define:{
IS_DEV:false,
CODE_FOR_IE:true
}
}]
});
The example code above will become
console.log('track infomation')
var foo;
foo=1;
Options
The available options are
{
define:{
APP_VERSION:'1.0.0',
IS_DEV:true
},
dropDebugger:false
}
- any variable same with key name in define object will be replace by its value
- when dropDebugger set true, the
debugger;
statement will be removed
