Queueing jobs in Node.js using PostgreSQL like a boss.

PostgreSql Version npm version Build Coverage Status

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 SKIP LOCKED, a feature added to postgres specifically for message queues, in order to resolve record locking challenges inherent with relational databases. This brings the safety of guaranteed atomic commits of a relational database to your 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.


  • Exactly-once job delivery
  • Backpressure-compatible polling workers
  • Cron scheduling
  • Pub/sub API for fan-out queue relationships
  • Deferral, retries (with exponential backoff), rate limiting, debouncing
  • Completion jobs for orchestrations/sagas
  • Direct table access for bulk loads via COPY or INSERT
  • Multi-master compatible (for example, in a Kubernetes ReplicaSet)
  • Automatic creation and migration of storage tables
  • Automatic maintenance operations to manage table growth


  • Node 16 or higher
  • PostgreSQL 11 or higher


# npm
npm install pg-boss

# yarn
yarn add pg-boss



To setup a development environment for this library:

git clone
npm install

To run the test suite, linter and code coverage:

npm run cover

The test suite will try and create a new database named pgboss. The config.json file has the default credentials to connect to postgres.
