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 🙏

Test Library for TypeScript

This is a simple test suite built using TypeScript inspired by Scheme's test engine/racket tests.

Install with npm i typescript-test-library

Methods:

Methods passed to tests must either be lambda functions, or take no values (and passed without parentheses). See examples.js for details.

| Methods | Params | Return | Description | |---------------|-----------------------------------------------------------------------------------------------------------------------------------|--------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | test | void | void | Main test method. Runs all stored check methods. Prints results to the console. | | checkStatisfy | func: Function to be tested.pred: Predicate function to be tested against. | void | Adds an anonymous function to the global tester_arr array to be tested by the test method. Checks to see if return value of func makes pred return true. | | checkExpect | func: Function to be tested.epected: Expected result of func | void | Adds an anonymous function to the global tester_arr array to be tested by the test method. Checks to see if output of function is the same as expected value. | | checkWithin | func: Function to be tested.expected: Expected result of func.tolerance: Amount func's return value can stray +/- from expected | void | Adds an anonymous function to the global tester_arr array to be tested by the test method. Checks to see if output of function is within tolerance of expected value. | | checkRange | func: Function to be tested.minVal: Lower bound to test against.maxVal: Upper bound to test against. | void | Adds an anonymous function to the global tester_arr array to be tested by the test method. Checks to see if output of function is within given range. | | checkError | func: Function to be tested.message: Expected error message from func, optional. | void | Adds an anonymous function to the global tester_arr array to be tested by the test method. Checks to see if function throws error, optionally checks if error message is the same as expected. | | silenceTest | val: Boolean value to set output, optional. | Bool | Stores boolean value that determines if failded test results are logged. If no value is given, returns stored value. | | executeTest | val: Boolean value to set execution, optional. | Bool | Stores boolean value that determines if tests are executed. If no value is given, returns stored value. | | preserveTest | val: Boolean value to set execution, optional. | Bool | Stores boolean value that determines if tests cleared after they are tested. If no value is given, returns stored value. | | clearTests | void | Void | Clears tests stored in the test array. Allows you to test new functions without having old ones be retested. |

See examples.js for example uses.
