plugin-error

What is plugin-error?

The plugin-error npm package is designed to simplify error handling in plugin development, particularly for Gulp plugins. It provides a consistent way to create and manage errors, making it easier to debug and handle errors in a standardized manner.

What are plugin-error's main functionalities?

Creating a PluginError

This feature allows you to create a new PluginError instance. The first argument is the plugin name, and the second argument is the error message. This helps in identifying which plugin caused the error.

const PluginError = require('plugin-error');
const err = new PluginError('MyPlugin', 'Something went wrong!');
console.error(err.toString());

Handling Error Options

This feature allows you to pass an options object to the PluginError constructor. The options can include properties like 'message' and 'showStack' to customize the error output.

const PluginError = require('plugin-error');
const err = new PluginError('MyPlugin', {
  message: 'Something went wrong!',
  showStack: true
});
console.error(err.toString());

Using Error Codes

This feature allows you to specify an error code, which can be useful for programmatically identifying different types of errors.

const PluginError = require('plugin-error');
const err = new PluginError('MyPlugin', {
  message: 'Something went wrong!',
  code: 'EPLUGIN'
});
console.error(err.toString());

Usage

  message: 'something broke'
});

var err = new PluginError({
  plugin: 'test',
  message: 'something broke'
});

var err = new PluginError('test', 'something broke');

var err = new PluginError('test', 'something broke', { showStack: true });

var existingError = new Error('OMG');
var err = new PluginError('test', existingError, { showStack: true });

API

new PluginError(pluginName, message[, options])

Error constructor that takes:

• pluginName - a String that should be the module name of your plugin
• message - a String message or an existing Error object
• options - an Object of your options

Behavior:

• By default the stack will not be shown. Set options.showStack to true if you think the stack is important for your error.
• If you pass an error object as the message the stack will be pulled from that, otherwise one will be created.
• If you pass in a custom stack string you need to include the message along with that.
• Error properties will be included in err.toString(), but may be omitted by including { showProperties: false } in the options.
