Protocol and Reference Implementation
Mercure is a protocol allowing to push data updates to web browsers and other HTTP clients in a convenient, fast, reliable and battery-efficient way. It is especially useful to publish async and real-time updates of resources served through web APIs, to reactive web and mobile apps.
A reference, production-grade, implementation of a Mercure hub (the server) is also available in this repository. It's a free software (AGPL) written in Go. It is provided along with a library that can be used in any Go application to implement the Mercure protocol directly (without a hub) and an official Docker image.
In addition, a managed and high-scalability version of the Mercure.rocks hub is available on Mercure.rocks.
