This repo contains open source components of Prisma Pulse.
This includes:
@prisma/pulse-cdc-pgfor consuming PostgreSQL logical replication data in JavaScript applications.- more to come 👀
Prisma Pulse extends from the components of this repository by adding robust infrastructure and event persistence, enabling teams to deploy real-time applications and event-driven architectures without maintaining complex infrastructure.
Prisma Pulse is a managed Change Data Capture (CDC) service that makes it easy to react to changes in your databases with type-safe model streams.
It enables developers to build real-time apps by streaming database changes into their application in a type-safe way — with just a few lines of code:
// 1. Subscribe to all changes on the `User` table
const stream = await prisma.user.stream();
// 2. Wait for changes to happen in the DB so that new events arrive
for await (let event of stream) {
// 3. Do something with an event, e.g. log the its details to the terminal
console.log(`Something happened in the database: `, event);
}Here is an overview of the main features Prisma Pulse provides:
- Type-safe reactions to database changes
- Delivery guarantees for events: "at least once" and in the "right order"
- Resumable event streams in case your server goes down
- Unidirectional data flow via Change Data Capture (CDC)
- Great DX integrated with usage of Prisma ORM (easy setup, development and maintenance)
- Compatibility with your existing database
- Insights dashboard, so you can view and understand all database events captured by Pulse
