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 🙏

accelerate-contract

⚠️ Warning: This package is intended for Prisma's internal use. Its release cycle does not follow SemVer, which means we might release breaking changes (change APIs, remove functionality) without any prior warning.

Purpose

Accelerate has ownership of the DataProxyEngine (now AccelerateEngine). This engine is handed over to the Client by the Accelerate extension. The Client uses the engine to communicate with the Accelerate service. Accelerate uses the Client to formulate and execute queries. This means we need some kind of contract between the Client and the Accelerate service.

If the Client breaks this contract, that translates into a breaking change for Accelerate users. This is why we need to be very careful when changing the AccelerateEngine and the AccelerateEngineConfig.

How it works

Both @prisma/client and @prisma/extension-accelerate will both pin this package to an agreed same specific version (eg. 5.10.0-dev.45). In turn this will prevent @prisma/extension-accelerate from deviating from the API provided by @prisma/client, and it will prevent @prisma/client from introducing backwards incompatible changes to the internal AccelerateEngineConfig.

This is one safe-guard to catch breaking changes statically via TypeScript. That's in addition to running all our functional tests as usual.

What it contains

This package contains the AccelerateEngineConfig and AccelerateEngine types. They are the contract that the Client and the Accelerate extension agree upon.
