})pg-boss is a job queue built in Node.js on top of PostgreSQL in order to provide background processing and reliable asynchronous execution to Node.js applications.
pg-boss relies on Postgres's SKIP LOCKED, a feature built specifically for message queues to resolve record locking challenges inherent with relational databases. This provides exactly-once delivery and the safety of guaranteed atomic commits to asynchronous job processing.
This will likely cater the most to teams already familiar with the simplicity of relational database semantics and operations (SQL, querying, and backups). It will be especially useful to those already relying on PostgreSQL that want to limit how many systems are required to monitor and support in their architecture.
A web-based dashboard is available for monitoring and managing pg-boss job queues. It provides an overview of queue statistics, job browsing and filtering, job actions (create, cancel, retry, resume, delete), warning history, and multi-database support.

To setup a development environment for this library:
git clone https://github.com/timgit/pg-boss.git
npm installTo run the test suite, linter and code coverage:
npm run coverThe test suite will try and create a new database named pgboss. The config.json file has the default credentials to connect to postgres.
The Docker Compose file can be used to start a local postgres instance for testing:
docker compose up
