This repository contains a small CLI application to handle data file diffs coming from Dialect map data repository interactions.

Furthermore, it parses those diffs into JSON messages that are published to a GCP Pub/Sub topic. Thanks to the use of Pub/Sub, these messages can be fanned out into a wide range of data-ingestion jobs.

All dependencies can be installed by running:

npm install

All JavaScript files are formatted using Prettier, and the custom properties defined in the .prettierrc.json file. To check for code style inconsistencies:

make check

Project testing is performed using Mocha. In order to run the tests:

make test

The package exposes a series of CLI commands to deal with data files differences. Each command has its own set of arguments and options.

Parses diff files and publish self-container change messages to a Pub/Sub topic.

dm-diff publish <data_file_path> <diff_file_path> <options>
