CLI TypeScript File Processor

This project serves as a boilerplate for creating a containerized TypeScript script that can be executed either as a standalone command or as a long-running service. It shows how to build, run, and manage a TypeScript-based Node.js CLI tool inside a Docker container.

How It Works:

1. Input: The tool reads a JSON file from the data directory (e.g., data.json).
2. Processing: It extracts the message field from the input file, appends the current timestamp, and processes the data.
3. Output: The processed data is appended to output/output.json. If the file doesn’t exist, it creates it, or if it exists, it adds the new entry.

Build & Run

1. docker compose up

Develop
