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 🙏

npm-install-checks

Check the engines and platform fields in package.json

API

Both functions will throw an error if the check fails, or return undefined if everything is ok.

Errors have a required and current fields.

.checkEngine(pkg, npmVer, nodeVer, force = false)

Check if a package's engines.node and engines.npm match the running system.

force argument will override the node version check, but not the npm version check, as this typically would indicate that the current version of npm is unable to install the package properly for some reason.

Error code: 'EBADENGINE'

.checkPlatform(pkg, force, environment)

Check if a package's os, cpu and libc match the running system.

force argument skips all checks.

environment overrides the execution environment which comes from process.platform process.arch and current libc environment by default. environment.os environment.cpu and environment.libc are available.

Error code: 'EBADPLATFORM'

.checkDevEngines(wanted, current, opts)

Check if a package's devEngines property matches the current system environment.

Returns an array of Error objects, some of which may be warnings, this can be checked with .isError and .isWarn. Errors correspond to an error for a given "engine" failure, reasons for each engine "dependency" failure can be found within .errors.
