easily create meaningful errors

npm install @amphibian/errors

var errors = require('@amphibian/errors');

try {
    throw errors.invalidInput('invalid_email_address', 'email', '[e-mail]');
} catch (error) {
    console.log(error);

    /*
    {
        [Error: Invalid Input (invalid_email_address): email [e-mail]]
            status: 400,
            type: 'invalid_input',
            code: 'invalid_email_address',
            data: ['email', '[e-mail]']

    */
}

Create your own error

var myError = errors.newError('My Error', {
    status: 400,
    type: 'my_error',
    class: TypeError,
    stack: true
});

try {
    throw myError('my_error_code', 'Some description', 382763);
} catch (error) {
    console.log(error);

    /*
    {
        TypeError: My Error (my_error_code): Some description 382763
            at [[... stack trace ...]]

            status: 400,
            type: 'my_error',
            code: 'my_error_code',
            data: ['Some description', 'Some more information here']
