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

Basura

Generate trash JavaScript. This is useful for testing libraries and APIs.

The strings that are generated are random, but every string comes from a single Unicode script, so they at least look vaguely interesting.

Install

npm install basura

Command line

Usage: basura [options]

Generate a random JavaScript object

Options:
  -V, --version                output the version number
  -a, --arrayLength <number>   Maximum array/object size (default: 10)
  -b, --noBoxed                Do not generate boxed types, like
                               String.
  -c, --cborSafe               Do not generate types that break CBOR.
  -d, --depth <number>         Maximum depth. (default: 5)
  -e, --edgeFreq <number>      Edge case frequency. (default: 0.1)
  -i, --import <file>          Import the given file, and use its
                               default export as an additional type
                               generator.  Can be specified multiple
                               times. (default: [])
  -j, --json                   Output JSON, not generating any types
                               that will not fit.
  -o, --output <file>          File to output.
  -s, --stringLength <number>  Maximum string length. (default: 20)
  -t, --type <type>            Generate this specific type.
  -T, --listTypes              List all supported types, then exit.

API

Full API docs are available.

import {Basura} from 'basura'

// The default options.  No need to pass anything in if you like these
const opts = {
  arrayLength: 10,  // maximum size of arrays and objects
  cborSafe: false,  // generate only CBOR-safe types?
  depth: 5,         // How deep to go
  edgeFreq: 0.1,    // How often to prefer edge cases?
  jsonSafe: false,  // generate only JSON-safe types?
  noBoxed: false,   // ignore boxed types, like String?
  output: false,    // add custom inspect functions that make output parseable JS?
  scripts: [],      // Array of script names to limit output to.  Defaults to all
  stringLength: 20, // Maximum string and Buffer length, in codepoints
  types: {},        // Extra types to generate.  Pass in `{Date: null}` to not generate Dates
}
const b = new Basura(opts)
console.log(b.generate_Date()) // Example output: 2011-02-16T11:28:41.539Z
console.log(b.generate()) // Some possibly-large chunk of JS
