I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

jest jest-environment mongo mongodb typescript ephemeral

jest-environment-mongodb-ephemeral

This package provides a wrapper around jest-environment-mongodb with the storageEngine setting preconfigured to ephemeralForTest.

This makes it possible to set the storage engine on a per test file basis via docblocks, without setting up Jest projects.

Installation

NPM

npm install --save-dev mongodb-memory-server jest-environment-mongodb-ephemeral

Yarn

yarn add --dev mongodb-memory-server jest-environment-mongodb-ephemeral

Usage

By adding a @jest-environment docblock at the top of a test file, you can specify mongodb-ephemeral to be used for all tests in that file:

/**
 * @jest-environment mongodb-ephemeral
 */

This overrides any environment set by testEnvironment in the Jest configuration file.

Additionally, any instance.storageEngine option provided by testEnvironmentOptions will be overridden with ephemeralForTest. All other options provided by testEnvironmentOptions will be in effect.
