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 🙏

chai-param-nn

v0.0.4

Published

Adds useful methods for using chai to validate function parameters

Downloads

Readme

This is a fork of the popular but abandoned npm package chai-param (https://github.com/theblacksmith/chai-param).

Import path has been fixed to support modern Node.js versions.

chai-param-nn

Use chai to validate your method's parameters

Quick start

Install it on your project

npm install chai-param-nn

Require and load it

var chai = require('chai'),
    chaiParam = require('chai-param-nn'),
    expect = chai.expect,
    should = chai.should(),
    param = chaiParam.param;

chai.use(chaiParam);

Happy method guarding :)

function register(user, pass) {
	// using should
	param(user, 'user', 'UsersCtl.register').should.not.be.empty;

	// or using expect
	expect(user).param('user', 'UsersCtl.register')
		.to.have.length.above(5)
		.and.below(16);
}

Config

chai-param-nn can be configured by setting the values in chaiParam.config object properties. E.g:

var chaiParam = require('chai-param-nn');

chaiParam.config.improveMessages = true;

improveMessages

Type: Boolean Default: true

Controls whether or not chai-param-nn should replace chai's messages by more descriptive ones. So, for example, instead of getting

UserCtl.register: expected 'asdf' to have a length above 5 but got 4

You'll get...

Improved error message

showCaller on error messages

Type: Boolean Default: true

This option is only available for node and requires improveMessages to be true.

chaiParam.config.showCaller = true;

disableColors

Type: Boolean Default: false

Disables message coloring. Boring, but useful for tests.
