*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**](https://mercure.rocks/docs/hub/install) (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](https://mercure.rocks/pricing). ## Contributing See [CONTRIBUTING.md](CONTRIBUTING.md). ## License and Copyright See https://mercure.rocks/docs/hub/license. ## Credits Created by [Kévin Dunglas](https://dunglas.fr).
