Readme

safe-event-emitter

An EventEmitter that isolates the emitter from errors in handlers. If an error is thrown in a handler it is caught and re-thrown inside of a setTimeout so as to not interrupt the emitter's code flow.

The API is the same as a core EventEmitter.

Install

$ yarn add '@metamask/safe-event-emitter'

Usage

import SafeEventEmitter from '@metamask/safe-event-emitter';

const ee = new SafeEventEmitter();
ee.on('boom', () => { throw new Error(); });
ee.emit('boom'); // No error here

// Error is thrown after setTimeout

Release & Publishing

Create a release branch

- To update an older maintained major version, base the release branch on the major version branch (e.g. 1.x)
Update the changelog
Update version in package.json file (e.g. yarn version --minor --no-git-tag-version)
Create a pull request targeting the base branch (e.g. master or 1.x)
Code review and QA
