RESTHeart provides:

1. Out of the box data persistence on MongoDB and any compatible database, like AWS DocumentDB or Azure Cosmos DB, with REST, GraphQL and WebSocket APIs.
2. Declarative authentication, authorization and user management for your applications.
3. Polyglot development framework supporting Java, Kotlin, JavaScript and TypeScript.

With RESTHeart you can access 100% of MongoDB capabilities with plain HTTP calls, no programming is needed!

Note: Book a free 1-to-1 demo and ask us anything!

At startup, RESTHeart connects automatically to the configured MongoDB database and exposes it via a complete API. See the below example session that uses HTTPie for REST calls:

Developers can save at least 80% of backend code to manage security and serve content to Mobile Apps, Angular, React, Vue or other SPA frameworks.

RESTHeart embeds Undertow, a flexible and performant web server written in Java, providing both blocking and non-blocking HTTP API’s based on NIO. Undertow is the underlying HTTP server of RedHat's Wildfly.

RESTHeart works out-of-the-box by merely installing and configuring it. It is particularly suitable to run as a Docker container, so it works perfectly in Kubernetes and AWS ECS clusters.

RESTHeart also supports GraalVM, a new Java Virtual Machine from Oracle that offers a polyglot runtime environment and the ability to compile Java applications to native binary images.

Ther internal architecture is based on plugins and exposes an API that allows to implement additional custom services in Java, Kotlin, JavaScript or TypeScript.

To extend the default behavior you can implement the following Java interfaces:

• Service - extend the API adding Web Services.
• Interceptor - snoop and modify requests and responses at different stages of the request lifecycle.
• Initializer - execute initialization logic at startup time.
• Providers - implement the Dependency Injection mechanism to provide objects to other plugins via the @Inject annotation.

The GraphQL default plugin works side by side with the already existing REST endpoints to get a managed, unified GraphQL API for modern applications.

The embedded WebSocket server can expose MongoDB's Change Streams, which allow applications to access real-time data changes.

For all these reasons, RESTHeart is the perfect "low code", self-contained backend for modern Web and Mobile apps, designed to radically simplify development and deployment.

Find setup instructions at Setup documentation page.

Note: Building RESTHeart from scratch requires at least Java 17 and maven 3.6.

$ ./mvnw clean package

You can then run it with (make sure to have mongod running on localhost:27017):

$ java -jar core/target/restheart.jar

To execute the integration test suite:

$ ./mvnw clean verify

The verify goal starts the RESTHeart process and a MongoDB Docker container before running the integration tests.

To avoid starting the MongoDB Docker container, specify the system property -P-mongodb.

The integration tests use the MongoDB connection string mongodb://127.0.0.1 by default. To use a different connection string, specify the property test-connection-string.

The following example shows how to run the integration test suite against an instance of FerretDB running on localhost.

# run FerretDB
$ docker run -d --rm --name ferretdb -p 27017:27017 ghcr.io/ferretdb/all-in-one
# execute the integration tests
$ ./mvnw clean verify -DskipUTs -P-mongodb -Dtest-connection-string="mongodb://username:password@localhost/ferretdb?authMechanism=PLAIN" -Dkarate.options="--tags ~@requires-replica-set"

This example also specifies the karate options to skip tests tagged with requires-replica-set (FerretDB does not supports change stream and transactions) and -DskipUTs to skip the execution of unit tests.

Snapshot builds are available from sonatype.org

Docker images of snapshots are also available:

$ docker pull softinstigate/restheart-snapshot:[commit-short-hash]

For commit short hash you need the first 7 digits of the hash, e.g.

$ git log

commit 2108ce033da8a8c0b65afea0b5b478337e44e464 (HEAD -> master, origin/master, origin/HEAD)
Author: Andrea Di Cesare <[email protected]>
Date:   Fri Oct 22 12:46:00 2021 +0200

    :bookmark: Bump to version 6.2.0-SNAPSHOT

...

The short hash is 2108ce0 and the docker pull command is therefore

$ docker pull softinstigate/restheart-snapshot:2108ce0
