Non-blocking PostgreSQL client for Node.js. Pure JavaScript and optional native libpq bindings.

This repo is a monorepo which contains the core [pg](https://github.com/brianc/node-postgres/tree/master/packages/pg) module as well as a handful of related modules.

- [pg](https://github.com/brianc/node-postgres/tree/master/packages/pg)

- [pg-pool](https://github.com/brianc/node-postgres/tree/master/packages/pg-pool)

- [pg-cursor](https://github.com/brianc/node-postgres/tree/master/packages/pg-cursor)

- [pg-query-stream](https://github.com/brianc/node-postgres/tree/master/packages/pg-query-stream)

- [pg-connection-string](https://github.com/brianc/node-postgres/tree/master/packages/pg-connection-string)

Each package in this repo should have it's own readme more focused on how to develop/contribute. For overall documentation on the project and the related modules managed by this repo please see:

* Pure JavaScript client and native libpq bindings share _the same API_

* Connection pooling

* Extensible JS ↔ PostgreSQL data-type coercion

* Supported PostgreSQL features

* Parameterized queries

* Named statements with query plan caching

* Async notifications with `LISTEN/NOTIFY`

* Bulk import & export with `COPY TO/COPY FROM`

node-postgres is by design pretty light on abstractions. These are some handy modules we've been using over the years to complete the picture.

node-postgres is free software. If you encounter a bug with the library please open an issue on the [GitHub repo](https://github.com/brianc/node-postgres). If you have questions unanswered by the documentation please open an issue pointing out how the documentation was unclear & I will do my best to make it better!
