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.
- Input: The tool reads a JSON file from the
datadirectory (e.g.,data.json). - Processing: It extracts the
messagefield from the input file, appends the current timestamp, and processes the data. - 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.
