Learn Grunt, Mocha and Tachyons

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is very easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

You can easily add CSS libraries to Nuxt using `yarn` or `npm` to install them, then simply adding them to the `nuxt.config.js` so they're included in each page. Then all the classes will be available for use in all of your templates. This lesson walks your through installing a library then adding it to your `nuxt.config.js`.

Add CSS Libraries to Nuxt

AngularJS is an open-source JavaScript framework, maintained by Google, that assists with running single-page applications. Its goal is to augment web-based applications with model–view–controller (MVC) capability, in an effort to make both development and testing easier.

Task automation is critical for any AngularJS single-page application. Grunt gets the job done.

Introduction to Grunt for Angular

Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases.

Every dependable library needs to have tests to ensure that you don't push accidental bugs. In this lesson, see how you can set up mocha and chai to start testing your library.

Setting up Unit Testing with Mocha and Chai

Now that you've got everything set up with mocha and chai, it's time to actually write tests. In this lesson you'll learn how to use `describe` and `it` to outline your tests and make sure you don't break your library in the future.

Unit Testing with Mocha and Chai

Mocha is a testing framework that provides structure for unit tests. In this lesson, we will be setting up Mocha with npm and npm scripts, writing a "Hello World" unit test, then writing the code to make the test pass (as an example of Test Driven Development (TDD), with the "red-green-refactor" workflow).

JavaScript Testing Fundamentals: Hello world unit test with Mocha (in ES6)

In this lesson, we will use Chai's request method to test our Node application's API responses.
By the end of this lesson, you will know how to:
- install the prerequisites to use mocha and chai in your application
- test for HTTP status response codes
- test for a string of text on a page
- test for a json response and validate the properties of the object
- write tests that not only verify the response of your application, but the behavior as well

grunt

GruntJS allows you to use underscore/erb style templates to reduce repetition and create variables. This is commonly used to point at build folders and files within your application's structure.

In this lesson John will show you how to start using Grunt Uglify to compress your javascript for production deployment.

Uglify

Grunt Multitask allows you to write complex tasks that run multiple targets. In this lesson, John will show you how to use Multitask in your GruntJS builds.

Multitask

You can use Grunt to combine all of your Javascript files into a single concatenated file.

Functional css for humans.

Quickly build and design new UI without writing css.

tachyons

Tachyons provides extensions (-ns, -m, and -l) to many of its classes to help you design for responsive layouts. This lesson walks you through designing for mobile first then adding a design for desktop.

Chai is a BDD / TDD assertion library for node and the browser that can be delightfully paired with any javascript testing framework.

chai

Writing great ES6 style Promises for Node.js is only half the battle. Your great modules must include tests as well to ensure future iterations don't break them. In this lesson, I show you a simple ES6 Promise in Node.js, then walk you through creating tests in Mocha using chai and chai-as-promised to test both resolve and reject methods.

Testing ES6 Promises in Node.js using Mocha and Chai

For production we want to use minified javascript to reduce the payload that is sent from the server. This can easily be accomplished with grunt-uglify.

Minifying your output with grunt-uglify

In this lesson John will show you how to get started with grunt-contrib-watch. Watch is an essential component of any Grunt build, and you will find yourself using it in almost every project. 

Grunt Watch

Grunt will clean up your build with the grunt-contrib-clean to make sure that no artifacts from previous builds are hanging around.

Cleaning your build folder with grunt-contrib-clean

With Grunt you can automate core tasks for your AngularJS project. In this lesson we will take a look at converting Stylus files to CSS, and add a watch task to convert those files automatically whenever a change is detected.

Development Automation Tasks with Grunt

Building responsive css layouts is critical in any modern website. Tachyons makes this easy by designing for mobile first then enabling you to switch directions and positions of elements when the site scales up to desktop sizes. This lesson walks you through using Tachyons with flexbox and leveraging the `flex-column` and `flex-row` classes to respond to mobile and desktop sizes.

In this lesson, you will learn how to verify your API server is returning HTTP 400 responses when clients submit incorrect data. Returning HTTP 400 ensures that your clients are notified of the incorrect usage. Testing for them ensures your API returns errors instead of incorrect responses when supplied with incorrect data.

Test for HTTP 400 responses with Mocha and Chai

Build and watch ECMAscript 6 using traceur compiler and Grunt.

In this lesson John will show you how to create a simple external config file for your GruntJS build.

External Config

In this lesson you will install GruntJS and get up and running with your first task, initial configuration, and how to get Grunt methods auto-completing in WebStorm.
