NestJS GraphQL + TypeORM + Redis API

This application provides a basic CRUD API with NestJS, TypeORM, GraphQL, and Redis for caching. It is fully containerized with Docker, allowing you to spin up NestJS, PostgreSQL, and Redis in one command.

---

Prerequisites

• Docker installed on your machine
• Docker Compose installed

---

Getting Started

Clone the repository, then open a terminal in the project root.

1. Build and Run Containers

Run the following command to build and start all containers (NestJS, Redis, and Postgres):

docker-compose up --build

• NestJS (app container) is exposed on port 3000.
• Redis runs internally on port 6379, mapped to the same port on your host.
• PostgreSQL runs on port 5432, also mapped to port 5432 on your host.

Once everything starts successfully, you can access the NestJS API at http://localhost:3000

Using the API with Postman

A Postman collection containing all the API requests is provided in the postman folder of this project.

1. Open Postman.
2. Click on Import in the top-left corner.
3. Select the File tab.
4. Click on Upload Files.
5. Navigate to the project directory, go to the postman folder, and select NestJS GraphQL API.postman_collection.json.
