Novices Performing Miracles

    try.catch

    try.catch Build Status

    Simple performant try-catch wrapper.

    This utility is used in place of regular try/catch blocks using a clean functional syntax. Execution is fully synchronous; this does not work with async methods

    Instead of this

     
    try {
        // do something
    }
    catch (err) {
        // handle errors
    }
    finally {
        // finally do something
    }
     

    Do this

     
    var Try = require('try.catch');
     
    Try(function () {
        // do something
    })
    .catch(function (err) {
        // handle errors
    })
    .finally(function () {
        // finally do something
    });
     

    It can also be used like this:

     
    function doSomething (x, y) {
        return this + x * y;
    }
     
    var result = Try(doSomething, 'test', 2, 3)     // pass context and arguments to function
    .catch(function (err) {
        // err was thrown
    })                                              // chain catch blocks
    .catch(TypeError, function (err) {              // catch errors conditionally
        // TypeError was thrown
    })
    .finally(function (value, err) {
        // finally do something
    });
     
    console.log(result.value); // return value of function if any
    console.log(result.error); // error thrown if any
