Learn Grunt, Jq and Reactfire

jq is a lightweight and flexible command-line JSON processor.

jq can help you quickly filter massive amounts of JSON data, but how can you turn it into a CSV, so you can process it quickly with a database or spreadsheet application?

This lesson shows how to select the data you want for your CSV with jq, and uses the helper utility linked below to output as CSV.

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

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.

jq is a lightweight and flexible command-line JSON processor. It is extremely useful for processing data from APIs to better understand the data your code will be consuming, before you write the code. In this lesson I introduce you to jq and show you the basic features it provides using the Star Wars API (http://swapi.co) as our data source. Topics covered include filtering, piping, object construction and data manipulation.

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.

Concatenating Your Javascript with grunt-contrib-concat

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

React is one of the web’s most popular frameworks for building JavaScript applications. 

If you know what you’re doing, React can drastically simplify how you build, use, and maintain code.

Whether you’re a React newbie or you’re ready for advanced techniques, you can level-up with egghead. Explore our in-depth courses, lessons, and community resources to build more powerful applications and crack open your career.

react

React becomes incredibly powerful when coupled with a real-time backend like Firebase. See how easy it is to bring the two together and chat with Star Wars characters while you're at it.

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.

Introduction to Grunt

Bash, unfortunately, doesn’t ship with a command that can work with JSON natively. In this lesson, we’ll learn how to read and do basic queries on JSON with `jq`, an installable command line tool that makes working with JSON in bash really easy. We'll pipe the JSON output of the Github API to jq to extract values. 

Note: jq has to be installed. On macOS, the easiest way to do this is to run `brew install jq`.  To view install instructions for all platforms, see https://stedolan.github.io/jq/download/. 

Read and Use JSON in Bash with jq

In this lesson, we'll apply our `jq` skills and write a script that gets a list of dependencies from package.json and greps for usages of every package. If a package is unused, it's marked for removal.
