#Angular Material - Error State Matcher for Form Fields (2021)

⚠️ New to Angular? This is a great entry point to start: http://bit.ly/angular-for-beginners

In this advanced angular tutorial we will have a look at ErrorStateMatcher - the interface which controls when to highlight error state for angular material form fields. By default angular material inputs turn red as soon as input has been touched but is it always the behaviour we expect? I don’t think so… that’s why we have ErrorStateMatcher which gives us control over this behaviour. It is going to be very interesting. Enjoy watching :)

Install Angular - Angular Environment Setup Process

Angular is a TypeScript based framework that works in synchronization with HTML, CSS, and JavaScript. To work with angular, domain knowledge of these 3 is required.

  1. Installing Node.js and npm
  2. Installing Angular CLI
  3. Creating workspace
  4. Deploying your First App

In this article, you will get to know about the Angular Environment setup process. After reading this article, you will be able to install, setup, create, and launch your own application in Angular. So let’s start!!!

Angular environment setup

Install Angular in Easy Steps

For Installing Angular on your Machine, there are 2 prerequisites:

  • Node.js
  • npm Package Manager
Node.js

First you need to have Node.js installed as Angular require current, active LTS or maintenance LTS version of Node.js

Download and Install Node.js version suitable for your machine’s operating system.

Npm Package Manager

Angular, Angular CLI and Angular applications are dependent on npm packages. By installing Node.js, you have automatically installed the npm Package manager which will be the base for installing angular in your system. To check the presence of npm client and Angular version check of npm client, run this command:

  1. npm -v

Installing Angular CLI

  • Open Terminal/Command Prompt
  • To install Angular CLI, run the below command:
  1. npm install -g @angular/cli

installing angular CLI

· After executing the command, Angular CLI will get installed within some time. You can check it using the following command

  1. ng --version

Workspace Creation

Now as your Angular CLI is installed, you need to create a workspace to work upon your application. Methods for it are:

  • Using CLI
  • Using Visual Studio Code
1. Using CLI

To create a workspace:

  • Navigate to the desired directory where you want to create your workspace using cd command in the Terminal/Command prompt
  • Then in the directory write this command on your terminal and provide the name of the app which you want to create. In my case I have mentioned DataFlair:
  1. Ng new YourAppName

create angular workspace

  • After running this command, it will prompt you to select from various options about the CSS and other functionalities.

angular CSS options

  • To leave everything to default, simply press the Enter or the Return key.

Angular Form Generator & Pitfalls

Ever felt repetitive creating forms in your Angular Application? Let’s fix it.

Intro

During the Front-end development days it feels like there is a lot of repetitive code which I have to write to design my forms which are almost all the time very close one to another.

I’ve been recently looking into ways of automating it. The furthest I wanted to go was to have some kind of interface between a more friendly modelling object as well as to an interface to link my objects to the Angular Modelling Universe.

This way, I discovered there is already a library that could do it for me formly. But looking over their documentation I realized this is a little bit more than I wanted.

As a result, I ended writing my own form generator. You’ll see that except for two or three pitfalls this is rather easy to achieve.

Foreground

I’ll be using Angular Materials to generate my forms.

I have two tips to share about their design. It can be difficult to change the colors or design a theme for them. You’ll see the documentation on their side is rather not the best on this subject. My piece of advice, use  https://materialtheme.arcsine.dev/. In case you don’t know exactly what colors to use but you have a slight idea about it, I recommend using  https://www.cssportal.com/css-color-converter/0000D8. In the end you’ll definitely discover some very cool Angular Material Theme which you can even share with others.

Getting Started

First of all, we’ll organize our application on modules. When it comes to Angular I always split the code in presentation and business. From where I’m standing, presentation means those components that deal with UX functionality, they can work by themselves but they don’t make sense for a user taken alone; business are those components that configure and group together presentation through a context.
