Building a full-stack application can feel overwhelming at first — especially when handling frontend, backend, and database together.
Angular and NestJS provide a powerful combination that makes development structured, scalable, and easier to maintain.
In this guide, we will build a simple full-stack application step by step using Angular for the frontend and NestJS for the backend.
Why Angular + NestJS?
– Both use TypeScript
– Clean and scalable architecture
– Strong community support
– Ideal for enterprise applications
This combination allows developers to work efficiently without switching between different programming styles.
Step 1: Setting Up Backend (NestJS)
Install NestJS CLI:
npm i -g @nestjs/cli
Create project:
nest new backend
Run server:
npm run start
Create module:
nest g module tasks
nest g controller tasks
nest g service tasks
This creates a structured backend with a controller, service, and module.
Step 2: Setting Up Frontend (Angular)
Install Angular CLI:
npm install -g @angular/cli
Create project:
ng new frontend
Run app:
ng serve
Create component:
ng generate component tasks
Angular handles UI and API integration efficiently.
Step 3: Connecting Frontend and Backend
Angular communicates with NestJS using HTTP APIs.
Example:
http://localhost:3000/tasks
If a CORS error occurs, enable it in NestJS:
app.enableCors();
This allows smooth communication between the frontend and the backend.
Step 4: Database Integration (PostgreSQL)
Install dependencies:
npm install @nestjs/typeorm typeorm pg
Configure the database and create an entity.
This allows for storing and retrieving data dynamically.
Conclusion
Using Angular and NestJS together provides a powerful full stack development experience.
With proper structure, scalability, and TypeScript support, this stack is ideal for modern web applications.
This step-by-step approach helps beginners and professionals build applications efficiently.
