CRUD stands for Create, Read, Update and Delete and refer to the operations that we run against a database to createn retrieve and update data. In this example, the database is a Firestore database that exists on the cloud. The CLI will ask if you want to add routing to your project you can choose any option you want and which style sheet format you want to use You can select CSS. Now that your project is generated, you need to proceed with creating a Firebase project and a Firestore database.
For this matter, you simply need to go to the Firebase Console and create a new Firebase project.
Next go to your Firebase project overview then click on web and copy the config data. Finally, you have to set up Firebase in your project. You simply import AngularFireModule and AngularFireDatabaseModule and you add them to the imports array of the main application module. After setting up Firestore in your project, you can proceed with creating a model class.
In the simple example, we suppose that you are creating an insurance app where we need to manage a set of policies. An insurance application will often contain more that one type of data like clients, employees and policies etc. This is an example of an insurance policy with many fields and relationships with other entities omitted for the sake of simplicity. An Angular service allows you to encapsulate the code that could be repeated in many places in your project. Using the Angular CLI, run the following command to generate a service:.
Next, add the getPolicies method to retrieve the available policies from the Firestore collection:. You also need to add the createPolicy method to persist an insurance policy in the Firestore database:. Next, you need to add the updatePolicy method to update an insurance policy by its identifier:. Finally, you can add the deletePolicy method to delete an insurance policy by its identifier:.
After creating the model and service for creating, reading, updating and deleting insurance policies, you now need to create the component for testing our methods:. Toggle navigation Toggle Search.

This is not an advert for Google I get no kickbacks from them for this but merely an illustration of how Angular plays with the database. There are things missing like data validation and a million possible features that I can also add. The point is to set up in Angular as quickly as possible and get it working with a live database. In short, simply run these commands in your terminal in the directory where you want your Angular app to sit. Here are the commands and what they do.
When you create a new project via Angular CLI, it will create a new project folder for you. To do this, we write the code below:. All classes that you will see in the rest of this tutorial is from Materialize CSS, unless mentioned otherwise. This will allow the associated controller to use the variables typed into the form.

The latest version is Angular 8 which was released on May 28, There are many new features and enhancements to both the command-line interface and the framework itself which result in a performance-boost and smaller production bundles.
One interesting feature is the ng deploy command which allows developers to quickly build and deploy their Angular apps to popular hosting providers such as Firebase or GitHub. We'll implement real-world features like error handling and retrying failed HTTP requests. Head to a new terminal and execute the following command:. The CLI will prompt you and ask whether you would like to add Angular routing. Say Yes. It'll then ask which stylesheet format you would like to use.
