It is especially useful to publish real-time updates of resources served through web APIs, to reactive web and mobile apps. The Mercure Component implements the "publisher" part of [the Mercure Protocol](https://mercure.rocks). Getting Started --------------- [](#getting-started) ``` $ composer require symfony/mercure lcobucci/jwt ``` ``` // change these values accordingly to your hub installation const HUB_URL = 'https://demo.mercure.rocks/.well-known/mercure'; const JWT_SECRET = '!ChangeThisMercureHubJWTSecretKey!'; // Set up the JWT token provider // Alternatively, you can use the \Symfony\Component\Mercure\Jwt\StaticTokenProvider if you already have a JWT token $jwFactory = new \Symfony\Component\Mercure\Jwt\LcobucciFactory(JWT_SECRET); $provider = new \Symfony\Component\Mercure\Jwt\FactoryTokenProvider($jwFactory, publish: ['*']); $hub = new \Symfony\Component\Mercure\Hub(HUB_URL, $provider); // Serialize the update, and dispatch it to the hub, that will broadcast it to the clients $id = $hub->publish(new \Symfony\Component\Mercure\Update('https://example.com/books/1.jsonld', 'Hi from Symfony!')); ``` Resources --------- [](#resources) - [Documentation](https://symfony.com/doc/current/mercure.html) - [Contributing](https://symfony.com/doc/current/contributing/index.html) - [Report issues](https://github.com/symfony/mercure/issues) and [send Pull Requests](https://github.com/symfony/mercure/pulls)in the [`symfony/mercure` repository](https://github.com/symfony/mercure) ### Health Score 64 — FairBetter than 99% of packages Maintenance66 Regular maintenance activity Popularity68 Solid adoption and visibility Community40 Growing community involvement Maturity70 Established project with proven stability Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
