How to Use Tailwind's Just-in-Time Mode in Angular

Let’s learn about Tailwind’s Just-in-Time mode and how to use it in Angular.

Since v11.2, the Angular CLI natively supports Tailwind CSS. This means that, although we don’t have access to the underlying PostCSS pipeline, we can use Tailwind CSS without many hassles. If you have Tailwind installed and a tailwind.config.js file, the Angular CLI will automatically add Tailwind to the list of PostCSS plugins it uses when building or serving your application.

I’ve already written a guide on how to add Tailwind CSS to your Angular application. In this article, I would like to go a step further and talk about how we can use Tailwind’s just-in-time (JIT) compiler with Angular.

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!!!

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

· 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

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

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

I’ve already written a guide on how to add Tailwind CSS to your Angular application. In this article, I would like to go a step further and talk about how we can use Tailwind’s just-in-time (JIT) compiler with Angular.

What is Tailwind’s JIT compiler?

First of all, I want to point out that the JIT compiler is currently in preview. But I have been using it for quite some time in my projects and it works like a charm.

The default Tailwind compiler is an ahead-of-time (AOT) compiler that is designed to generate thousands of utility classes that we may or may not need. This results in a huge bundle size by default. But when building for production, Tailwind’s built-in PurgeCSS tool will analyze our code and remove from that huge bundle all the CSS that we’re not actually using in our application.

But, in development we still had to deal with that huge bundle which impacted browser performance but also resulted in slower startup time of our development server (ng serve). With the new JIT mode, the process is now reversed. The utility classes are generated on demand when we actually use them in our code.

The main benefits of the JIT mode are faster build times and better performance in development, but they’re not limited to these. The JIT mode has opened the door to great new features like the ability to generate custom utilities by using a syntax like bg-[#fefefe] which will generate the following CSS:

If you want to learn more about all the benefits of the new JIT mode, check out Tailwind Labs’ great video on the topic.

Enabling the just-in-time mode in Angular

To enable the just-in-time mode, there are two things we need to do:

• Set the mode option to jit in our tailwind.config.js file.
• Set the TAILWIND_MODE environment variable to build or watch.

But we also need to take into account our code editors because we still want to have intellisense when authoring our code. I use WebStorm which doesn’t support the new JIT mode yet. So I need a setup that uses the new JIT mode when I use the Angular CLI and Tailwind’s AOT mode for the IDE.

Basics of Angular: Part-1

What is Angular? What it does? How we implement it in a project? So, here are some basics of angular to let you learn more about angular.

Angular is a Typescript-based open-source front-end web application platform. The Angular Team at Google and a community of individuals and corporations lead it. Angular lets you extend HTML’s syntax to express your apps’ components clearly. The angular resolves challenges while developing a single page and cross-platform applications. So, here the meaning of the single-page applications in angular is that the index.html file serves the app. And, the index.html file links other files to it.

We build angular applications with basic concepts which are NgModules. It provides a compilation context for components. At the beginning of an angular project, the command-line interface provides a built-in component which is the root component. But, NgModule can add a number of additional components. These can be created through a template or loaded from a router. This is what a compilation context about.

What is a Component in Angular?

Components are key features in Angular. It controls a patch of the screen called a view. A couple of components that we create on our own helps to build a whole application. In the end, the root component or the app component holds our entire application. The component has its business logic that it does to support the view inside the class. The class interacts with the view through an API of properties and methods. All the components added by us in the application are not linked to the index.html. But, they link to the app.component.html through the selectors. A component can be a component and not only a typescript class by adding a decorator @Component. Then, for further access, a class can import it. The decorator contains some metadata like selector, template, and style. Here’s an example of how a component decorator looks like:

@Component({
    selector: 'app-root',
    templateUrl: 'app.component.html',
    styleUrls: ['app.component.scss']
})

Role of App Module

Modules are the package of functionalities of our app. It gives Angular the information about which features does my app has and what feature it uses. It is an empty Typescript class, but we transform it by adding a decorator @NgModule. So, we have four properties that we set up on the object pass to @NgModule. The four properties are declarations, imports, providers, and bootstrap. All the built-in new components add up to the declarations array in @NgModule.

@NgModule({
declarations: [
  AppComponent,
],
imports: [
  BrowserModule,
  HttpClientModule,
  AppRoutingModule,
  FormsModule
],
bootstrap: [AppComponent]
})

What is Data Binding?

Data Binding is the communication between the Typescript code of the component and the template. So, we have different kinds of data binding given below:

• When there is a requirement to output data from our Typescript code in the HTML template. String interpolation handles this purpose like {{data}} in HTML file. Property Binding is also used for this purpose like [property] = “data”.
• When we want to trigger any event like clicking a button. Event Binding works while we react to user events like (event) = “expression”.
• When we can react to user events and output something at the same time. Two-way Binding is used like [(ngModel)] = “data”.
