modern-errors plugin to print where to report bugs.

This appends a bug reports URL to error messages.

Adding the plugin to modern-errors.

import ModernError from 'modern-errors'

import modernErrorsBugs from 'modern-errors-bugs'

export const BaseError = ModernError.subclass('BaseError', {
  plugins: [modernErrorsBugs],
})

Configuring the bugs report URL.

export const UnknownError = BaseError.subclass('UnknownError', {
  bugs: 'https://github.com/my-name/my-project/issues',
})

Unknown errors now include the following message.

Please report this bug at: https://github.com/my-name/my-project/issues

npm install modern-errors-bugs

This package works in both Node.js >=18.18.0 and browsers.

This is an ES module. It must be loaded using an import or import() statement, not require(). If TypeScript is used, it must be configured to output ES modules, not CommonJS.

Type: Plugin

Plugin object to pass to the plugins option of ErrorClass.subclass().

The bug reports URL must be a string or a URL.

While this plugin is especially useful with unknown errors, it can also apply to (in priority order):

• Any error: second argument to ModernError.subclass()

export const BaseError = ModernError.subclass('BaseError', {
  plugins: [modernErrorsBugs],
  bugs: 'https://github.com/my-name/my-project/issues',
})

• Any error of a specific class (and its subclasses): second argument to ErrorClass.subclass()

export const UnknownError = BaseError.subclass('UnknownError', {
  bugs: 'https://github.com/my-name/my-project/issues',
})

• A specific error: second argument to new ErrorClass()

throw new ExampleError('...', {
  bugs: 'https://github.com/my-name/my-project/issues',
})

// package.json
// See https://docs.npmjs.com/cli/configuring-npm/package-json#bugs
{
  ...
  "bugs": {
    "url": "https://github.com/my-name/my-project/issues"
  },
  ...
}

import packageJson from '../../package.json' with { type: 'json' }

export const UnknownError = BaseError.subclass('UnknownError', {
  bugs: packageJson.bugs.url,
})
