Rush

The ultimate solution of writing asyncronous code in a beautiful way.

Installation

npm install rush

Example

var rush = require('rush');
var fs = require('fs');
 
rush({
    n: 0
    data: []
})(function() {
    this.n++;
    
    fs.readFile('file1.txt', this(function(data) {
        this.data.push(data);
    }));
    
    fs.readFile('file2.txt', this(function(data) {
        this.data.push(data);
    }));
})(function() {
    this.n++;
    
    fs.readFile('file3.txt', this(function(data) {
        this.data.push(data);
    }));
})(function(err) {
    if (err) {
        // Handle the error.
        return;
    }
 
    console.log(n); // => 2
 
    // this.data should have 3 items:
    // (data of) file1, file2, file3 or file2, file1, file3.
})();
 

Important

Multiple initializers are not working as intended currently.

You can use multiple initializers (passing of an object to Rush), but all these objects will be used like as you passed a single merged object at the beginning of the chain.

Don't rely on such behaviour, it will be fixed later.

rush({
    x: 2
})(function() {
    console.log(x); // Logs 3, but not 2!
})({
    x: 3
})(function() {
    console.log(x); // Logs 3 as intended.
})(function(err) {
    check(!err);
})();

You can use regular blocks instead of initializers, as blocks are executed strictly one after another (if there are no errors in them).
