logged-errors

This module is a simple fork of the restify-errors with some chainable features:

  • it can log the error using an external logger (e.g. winston)
  • it can show the error stack in the body of the error
  • it can format the log output
  • it works both in Node and browser

Installation

Install logged-errors as usual:

$ npm install --save logged-errors

For browser environment add logged-error.js file in build folder.

Example

// see the examples folder

// dependencies
var LoggedErrors = require('logged-errors');

// add the stack to the body of the error
throw new LoggedErrors.NotFoundError('some error').withStack().log();

// the following statements are equivalent
throw new LoggedErrors.NotFoundError('some error').withStack().toArray().log();
throw new LoggedErrors.NotFoundError('some error').withStack(true).log();

// set a new format and a custom logger (default is console)
LoggedErrors.set({
    format: function (e) {
        return 'error occurred: ' + e.message;
    },
    logger: require('winston')
});

// change on the fly the content used for the log using the defult format
// use body (default)
throw new LoggedErrors.NotFoundError('some error').log();
// use message (set mode !== 'body')
throw new LoggedErrors.NotFoundError('some error').log('msg');

// compose a message for the error
throw new LoggedErrors.NotFoundError('some error with %s and %s', 'first parameter', 'second parameter').log();
