    cbrun

    A very tiny library to invoke callbacks

    To install simply run:

    npm install cbrun

    This lib implements only one function. You can pass array of errors, what you pass to nested callbacks. On second argument you must put callback reference, third and further - it is arguments of callback, excluding error.

    function callbackHandler(errors[], callback, [arg_0, arg_1, ...]);

    Or you can put one error, but do not forget put callback anyway.

    function callbackHandler(error, callback, [arg_0, arg_1, ...]);

    This function exports to module, so you need to require it first:

    var callbackHandler = require('cbrun');
    var fs = require('fs');
     
    //Our function, what invokes callback 
    function readFiles(callback) {
      fs.readFile('file1', function (err, data1) {
        fs.readFile('file2', function (err1, data2) {
            //You dont need to check error in nested callbacks, only on endpoint 
            callbackHandler([err, err1], callback, data1, data2); 
        });
      });
    }
     
     
    //Usage of this function 
    readFiles(function (err, fileData1, fileData2) {
      if (err) {
        console.log(err);
        process.exit(1);
      }
      console.log(fileData1.toString(), fileData2.toString());
    });
     

    If you find bug, please open issue. Thanks ;)
