/pkg/rsnotify

Description

A notification library that supports listening for notifications. A broadcaster supports many-to-one listeners per notification, as well as waiting for a specific notification that matches a filter.

Examples

• markdownRenderer demonstrates how to use rsnotify to provide notification support for storage (rsstorage), caching (rscache), and job queueing (rsqueue).
• testnotify demonstrates sending notifications locally (no database) or between processes (using Postgres).

Implementations

Each listener implementation is a separate Go module.

listeners/local

For use in the context of a single process, the local implementation uses Go channels for notifications. The local implementation, in addition, provides a notification mechanism for sending the notifications.

listeners/postgrespgx

A github.com/jackc/pgx implementation that supports notifications using PostgreSQL's LISTEN feature. Notifications are sent by using your own code to NOTIFY PostgreSQL.

listeners/postgrespq

The lib/pq implementation should be considered BETA quality.

A github.com/lib/pq implementation that supports notifications using PostgreSQL's LISTEN feature. Notifications are sent by using your own code to NOTIFY PostgreSQL.
