Optimize Toolset

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.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

emulate-mongo-2-driver

Purpose

You have legacy code that depends on the 2.x version of the MongoDB Node.js driver. You don't want to upgrade to the 3.x driver because of backwards compability problems, but you don't have a choice because of reported vulnerabilities such as those detected by npm audit.

emulate-mongo-2-driver aims to be a highly compatible emulation of the 2.x version of the MongoDB Node.js driver, implemented as a wrapper for the 3.x driver.

It was created for long term support of ApostropheCMS 2.x. Of course, ApostropheCMS 3.x will use the MongoDB 3.x driver directly.

Usage

If you are using ApostropheCMS, this is standard beginning with version 2.101.0. You don't have to do anything. The example below is for those who wish to use this driver in non-ApostropheCMS projects.

npm install emulate-mongo-2-driver
const mongo = require('emulate-mongo-2-driver');

// Use it here as if it were the 2.x driver

Goals

This module aims for complete compatibility with the 2.x features mentioned as obsolete or changed here but there may be omissions. An emphasis has been placed on features used by ApostropheCMS but PRs for further compatibility are welcome.

What about those warnings?

"What about the warnings re: insert, update and ensureIndex operations being obsolete?"

Although deprecated, these operations are supported by the 3.x driver and work just fine.

However, since the preferred newer operations were also supported by the 2.x driver, the path forward is clear. We will migrate away from using them gradually, and you should do the same. It doesn't make sense to provide "deprecation-free" wrappers when doing the right thing is in easy reach.
