Customize SUCCESS method

Customize SUCCESS() method

The SUCCESS() method is the most used method in my Total.js applications. And few developers know that the output of this method can be changed to fit your needs.

How to modify it?

  • create a definition file called overrides.js
global.SUCCESS = function(success, value) {

    // Check if the "success" variable is a function
    if (typeof(success) === 'function') {
        return function(err, value) {
            success(err, SUCCESS(err, value));
        };
    }

    var err;

    if (success instanceof Error) {
        // Is "success" Error?
        err = success.toString();
        success = false;
    } else if (success instanceof ErrorBuilder) {
        // Maybe "success" is ErrorBuilder instance
        if (success.hasError()) {
            err = success.output();
            success = false;
        } else
            success = true;
    } else if (success == null)
        success = true;

    if (err)
        return { error: err };
    else if (success)
        return { ok: true };
    else
        return { error: 'Repeat your operation.' };
};

Usage examples:

console.log(SUCCESS(true));
// Output: { ok: true }

console.log(SUCCESS(false));
// Output: { error: 'Repeat your operation.' }

console.log(SUCCESS(false));
// Output: { error: 'Error: A bug' }

console.log(SUCCESS(new ErrorBuilder().push('', 'A bug')));
// Output: { error: [ { name: '', error: 'A bug', path: undefined, index: undefined } ] }

// the real purpose is to use it as a response in a controller
function some_controller() {
    this.json(SUCCESS(true));
}
