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 🙏

js-factories

Build Status NPM Version

js-factories is a library to use dynamic fixtures using Factories in javascript/coffeescript. Ideal to combine using Mocha/chai frameworks and test rich classes for MV** Frameworks like Backbone.js

Usage

Include js-factories.js in your test suite.

Factory support is added to quickly be able to build models or other objects as you see fit:

Factory.define 'user', (attributes = {}) ->
  new User attributes

Factory.create 'user', name: 'Matthijs'
Factory.createList 10, 'user', name: 'Matthijs'

Traits

you can also use 'traits'. Traits are flags that are set when the user calls create with the factory name prefixed with terms separated by dashes.

Like: 'female-admin-user'

This will call the 'user' factory, and provide the terms 'female' and 'admin' as traits for this user

this list is accessible in the factory callback using this.traits

There are 2 helper methods to help check if traits are set:

this.trait('returns', 'one', 'of', 'these', 'values')

and

this.is('admin') # returns a boolean value

Extended example:

Factory.define 'user', (attributes = {}) ->
  attributes.gender = @trait('male', 'female') || 'male'

  returningClass = User
  if @is('admin')
    returningClass = AdminUser

  new returningClass attributes

Factory.create 'user', name: 'Matthijs' # => new User name: 'Matthijs'
Factory.create 'male-user', name: 'Matthijs' # => new User name: 'Matthijs', gender: 'male'
Factory.create 'male-admin-user', name: 'Matthijs' # => new AdminUser name: 'Matthijs', gender: 'male'
Factory.create 'female-user', name: 'Beppie' # => new User name: 'Beppie', gender: 'female'

Sequences

Sequences are also supported:

Factory.define 'counter', ->
  {
    amount: @sequence('amount')
    other: @sequence('other')
  }

This does not conflict with similar names in other factory definitions.

You can also yield results:

Factory.define 'abc', ->
  @sequence (i) -> ['a','b','c'][i]

# results in:
Factory.create('abc') => 'a'
Factory.create('abc') => 'b'

Sampling

You can sample a value from a list

Factory.define 'sampler', ->
  @sample 'a', 'b', 'c'

Will randomly return a, b or c every time
