Building a Full-Stack Application with Angular and NestJS
In this article, we will explore how to build a full-stack application using Angular and NestJS. We will start by discussing the similarities between the two frameworks and then move on to setting up the development environment for both Angular and NestJS.
Similarities between Angular and NestJS
Angular and NestJS are both popular JavaScript frameworks used for building modern web applications. While Angular is primarily used for building client-side applications, NestJS is used for building server-side applications. Despite their differences, both frameworks share some common features, including:
- Component-based architecture
- Use of TypeScript
- Powerful tools for building dynamic and interactive user interfaces
Setting up the Development Environment
To start building our full-stack application, we need to set up the development environment for both Angular and NestJS.
Setting up the NestJS Project
To set up a new NestJS project, we can use the following command:
npm i -g @nestjs/cli
nest new tasks
This will create a new NestJS project called “tasks”. We can then navigate to the project directory and run the development server using the following command:
npm run start
Setting up the Angular Project
To set up a new Angular project, we can use the following command:
npm i -g @angular/cli
ng new tasks-ui
This will create a new Angular project called “tasks-ui”. We can then navigate to the project directory and run the development server using the following command:
ng serve
Creating the Task Application
Now that we have set up the development environment for both Angular and NestJS, we can start building our task application.
Creating the NestJS Service
To create a new NestJS service, we can use the following command:
nest generate service tasks
This will create a new file called “tasks.service.ts” in the “src” directory. We can then update this file to include the necessary logic for our task application.
Creating the Angular Service
To create a new Angular service, we can use the following command:
ng generate service tasks
This will create a new file called “tasks.service.ts” in the “src/app” directory. We can then update this file to include the necessary logic for our task application.
Updating the App Component
To use the tasks service in our Angular application, we need to update the app component. We can do this by injecting the tasks service into the app component constructor.
Updating the App Template
To display the tasks in our Angular application, we need to update the app template. We can do this by using the tasks service to retrieve the tasks and then displaying them in the template.
Testing the Full-Stack Application
To test our full-stack application, we can run the development servers for both Angular and NestJS. We can then navigate to the Angular application in our web browser and test the task functionality.
By following these steps, we can build a full-stack application using Angular and NestJS. This application can be used to manage tasks and includes features such as creating, reading, updating, and deleting tasks.
