Learn Ionic, Npm and Ruby

Get started building web applications with Angular and Firebase.

In this course, you'll learn how to set up and use Firebase in your Angular applications using the AngularFire library.

We choose the AngularFire library because it is an official library created by the Firebase and Angular teams to work better with Angular.

It helps you by wrapping everything into observables and helps update zones. 

By the end of this course, you'll be able to build web applications using Cloud Firestore as your database, Firebase Authentication as your Auth system, Cloud Storage to save files, and Firebase Hosting to deploy your applications to the web.

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.

A Monorepo is where you have multiple projects inside a singular repository.

Introduction to Monorepos with NPM Workspaces

You can’t be everywhere at once. Neither can node packages. But with a utility called npx — included in npm v5.2 and later — you can interact and run with node modules even if they’re not downloaded locally. The same is true for gists and remote branches of GitHub. As long as npm installed, your work can be wherever you are.

This course from Elijah Manor unlocks the power of the npx utility. Over 17 minutes, we will examine the npx package runner and look through various scenarios where the tool is helpful when running node packages from the command line. You’ll learn to use npm to:

- test out various versions of a package
- run packages without globally installing
- run code directly from GitHub
- make working with packages much easier

npm is the package manager for JavaScript. Find, share, and reuse packages of code from hundreds of thousands of developers — and assemble them in powerful new ways.

Building native mobile applications has traditionally been a completely foreign work flow than web development. Recently frameworks, such as Ionic and React Native, have been come out to create a similar web development workflow in a native environment. 

Ionic 2 builds on top of Angular to offer a complete framework for building mobile apps using HTML, CSS, and Javascript that target native mobile and the browser. We’ll work with the RandomUser API to create an employee directory that will let us view user details, update that information, and pass the data back and forth with Ionic 2 routing.

Angular is a development platform for creating applications using modern web standards. Angular includes a wealth of essential features such as mobile gestures, animations, filtering, routing, data binding, security, internationalization, and beautiful UI components. It's extremely modular, lightweight, and easy to learn.

Building apps with Ionic 2

In this course we will introduce the topic of using npm scripts as a build tool. We will start simple and then continue to build a small website as we introduce new topics. By the end of the course, you'll know how to get started and what tools and techniques are needed for you to create your own set of build scripts.

How to Use npm Scripts as Your Build Tool

A lot of the power behind npm scripts is creating custom scripts that are outside the basic set that npm natively understands. In this lesson we will install the ESLint node package, create a new eslint npm script, briefly discuss about environment variables and how npm knows where to find your binary, and then execute our custom script from the command line.

Rails is a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Controller (MVC) pattern.

Expanding on [Part 1](https://egghead.io/lessons/angularjs-rails-todo-api-part-1), this lesson will look at how to bootstrap AngularJS in a rails application as part of the asset pipeline. With Angular available, you'll see how to communicate with the Rails API using $resource.

Often times you’ll have variations that you’ll want to make to your npm scripts and repeating yourself is inefficient and verbose. Instead you can create a base script and pass arguments into it from another script.

Pass arguments to npm scripts

In this lesson we will look at pulling out complex npm script logic into an external JavaScript file. Instead of writing bash scripts you can leverage your JavaScript abilities to automate your build process. We’ll use some helper node modules such as shelljs, opn-cli, and babel-cli. 

Create a node script to replace a complex npm script

In addition to package.json level variables (such as name and version), you can have custom conf settings that can be used in your npm scripts. These config values can be overridden outside of the package.json by using the npm config set command if necessary.

Use custom config settings in your npm scripts

In this lesson we will examine two common scripts (start and test) that npm natively understands. We’ll define these scripts for our existing repository and show how you can run the scripts from the terminal.

Run the basic npm scripts

After creating several npm script it becomes useful to run multiple scripts back-to-back in series. This is a nice feature because you can enforce that one script needs to complete before starting another one.

Run npm scripts in series

In an effort to bypass saving temporary build files you can leverage piping and output redirection to streamline your build process. In addition using these technique can speed up your build process.

Pipe data from one npm script to another

In this lesson we will look about how we can integrate with git hooks to help enforce a certain level of quality before you either commit your code or push to a remote repository.

Run npm scripts with git hooks

There are times when it is helpful for a npm script to have lots of logs when trying to debug a problem, but there are other times when you want to run a script silently. Thankfully there are a range of flags to control the log level used when running npm scripts.

Change the level of console output when running npm scripts

In this lesson we will look at different ways you can list the available npm scripts. Whether we want to pipe `npm run` through `less` or install an npm package such as `completion` or `ntl`, we have many options to quickly execute scripts with shell tab completion.

List available npm scripts and support tab completion

A technique you might use once you start having lots of npm scripts is to use a node package that allows you to define your scripts in an external package-scripts.js file. By pulling out your scripts it can help with organization, enable better comments, provide shortcuts, and more.

Pull out npm scripts into another file with p-s

In the past, you've needed to either write a package.json script or use the `node_modules/.bin` directory to access binaries installed in your node_modules. npx enables you to access the binaries much more easily and try out options before you settle on what you want to add to your package.json scripts.

Run Local DevDependencies from the Command Line with npx

Gesture driven lists are a great way to take a simple UI element and make it fun. We'll look at how we can make swipe-able list items to reveal additional functionality, as well as being able to drag and reorder list items.

Use Sliding Gestures to Reorder an Ionic 2 List

In this lesson we will walk through how to break out code into it's own provider using the CLI. Ionic’s CLI provides a generate command that will quickly help create common components, pipes, providers, and much more. To see what kind of generators are available, run `ionic g --list` in your terminal. 

Use the Ionic CLI to Generate Angular 2 Mobile Components

In this lesson we'll show how to use yarn to alias the names of same npm libraries but install different versions. This could allow for easy migrating from one library version to an upgraded version.
