Pastebin Application

This is a simple web application that allows users to create and share text snippets (pastes). When a user submits text, the application generates a unique random URL where the content can be viewed. The data is stored in memory and expires after 24 hours.

Features

• Create text pastes.
• Generate a unique, random URL for each paste.
• View pastes at their unique URL.
• "Copy URL" button to easily share the link.
• Pastes automatically expire after 24 hours.
• In-memory storage, no database required.
• Dockerized for easy deployment.

Technology Stack

• Backend: Node.js, Express.js
• Template Engine: EJS (Embedded JavaScript)
• Containerization: Docker

Running Locally

1. Clone the repository (or set up the files as done previously).

2. Install dependencies:

   npm install

3. Start the server:

   npm start

4. Open your browser and navigate to http://localhost:3000.

Running with Docker

You can either build the Docker image from the source or pull the pre-built image from Docker Hub.

1. Build from Source

1. Build the Docker image:

   docker build -t pastebin-app .

2. Run the Docker container:

   docker run -d -p 3000:3000 --name pastebin-container pastebin-app

2. Pull from Docker Hub

The image is publicly available on Docker Hub.

1. Pull the image: You can pull either a specific version or the latest one.

   # Pull version 1
   docker pull jgkong/pastebin-app:1
   
   # Or pull the latest version
   docker pull jgkong/pastebin-app:latest

2. Run the Docker container:

   docker run -d -p 3000:3000 --name pastebin-container jgkong/pastebin-app:1

After running the container, the application will be accessible at http://localhost:3000.
