anhui

A light library creates a custom transform stream and avoids subclasses noise.

Inspired by through2

quick example

pipe consistently :+1:

fs.createReadStream('readable.txt')
	.pipe(anhui(function(chunk){
		return chunk.toString().toUpperCase();
	}))
	.pipe(fs.createWriteStream('writable.txt'));

Or object stream:

var myanhui = anhui(function(chunk){
	if (typeof chunk == "string"){
		return chunk.toString().toUpperCase();
	} else if (typeof chunk == "object"){
		var obj = chunk;
		if (obj.hasOwnProperty("zhc")) {
			obj.zhc = "321"
		} 
		return obj;
	}
},{objectMode:true});

// try it out
myanhui.on("data",function(chunk){
	console.log(chunk);
});

myanhui.write({zhc:"123"}); // input line 1
myanhui.write('another line\n');  // input line 2
myanhui.end();  // finish
