## Description
|
||||
|
||||
## Project Overview
|
||||
[Nest](https://github.com/nestjs/nest) framework TypeScript starter repository.
|
||||
|
||||
This project is a simple URL shortening microservice built with Nest.js. It provides the following features:
|
||||
|
||||
- URL Shortening: Convert long URLs into short, easy-to-share versions.
|
||||
- URL Expansion: Expand shortened URLs to their original long form And redirect users to the original URL.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
Before you begin, ensure you have met the following requirements:
|
||||
|
||||
- Node.js installed on your machine.
|
||||
- Docker and Docker Compose (if you prefer to use Docker).
|
||||
- `.env` file (if not using Docker) with the necessary environment variables. You can use .env.exmaple as a reference.
|
||||
|
||||
## Getting Started
|
||||
|
||||
To get the project up and running, follow the instructions below.
|
||||
|
||||
### Using Docker Compose
|
||||
|
||||
1. Clone the repository:
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
git clone https://github.com/your-username/tiny-url-microservice.git
|
||||
cd tiny-url-microservice
|
||||
docker-compose -f docker-compose.yaml up -d --build
|
||||
$ npm install
|
||||
```
|
||||
|
||||
Your Nest.js server should now be running on port as like the port from the .env file.
|
||||
|
||||
## API Routes
|
||||
# Shorten URL:
|
||||
|
||||
- Endpoint: POST /url-shortener/shorten
|
||||
- Request Body: { "url": "https://example.com" }
|
||||
- Response: { "data": "abc123", "status": 201 }
|
||||
Expand URL:
|
||||
|
||||
Endpoint: GET /url-shortener/:shortUrl
|
||||
Response: Redirects to the original long URL or redirect to the client UI 404 page if not found.
|
||||
|
||||
## Testing
|
||||
|
||||
To run the tests, run the following command:
|
||||
## Running the app
|
||||
|
||||
```bash
|
||||
npm run test
|
||||
# development
|
||||
$ npm run start
|
||||
|
||||
# watch mode
|
||||
$ npm run start:dev
|
||||
|
||||

|
||||
```
|
||||
|
||||
## Test
