Ready to use data API for MongoDB

Query documents from the command line with httpie.

The GET request has two query parameters: filter to apply a query and pagesize to limit the response to one document.
Here we use the brilliant httpie, a modern command line HTTP client.

More examples 
$ http -b GET https://demo.restheart.org/messages'?filter={"from":"Bob"}&pagesize=1'

[
    {
        "_id": {
            "$oid": "5c50963e477870eb8258fa68"
        },
        "from": "Bob",
        "message": "was here"
    }
]

Query documents from the command line with cURL.

The GET request has two query parameters: filter to apply a query (that needs to be encoded with --data-urlencode option since it contains the curly brackets) and pagesize to limit the response to one document.
Here we use the immortal cURL!

More examples 
$ curl -G --data-urlencode 'filter={"from":"Bob"}' https://demo.restheart.org/messages?pagesize=1

[
    {
        "_id": {
            "$oid": "5c50963e477870eb8258fa68"
        },
        "from": "Bob",
        "message": "was here",
    }
]

Query documents with JavaScript.

The GET request has two query parameters: filter to apply a query and pagesize to limit the response to one document.
Here we use the fetch API.

Run it 
const url = encodeURI('https://demo.restheart.org/messages?filter={"from":"Bob"}&pagesize=1');

fetch(url)
  .then(response => response.json())
  .then(json => JSON.stringify(json, null, 2))
  .then(docs => console.log(docs));

Query documents with Java.

The GET request has two query parameters: filter to apply a query and pagesize to limit the response to one document.
Here we use the unirest java http library.

More examples 
public void printOutMessages() throws UnirestException {
    var resp = Unirest.get("https://demo.restheart.org/messages")
            .queryString("filter", "{'from':'Bob'}")
            .queryString("pagesize", "1")
            .asJson();

    // print out each message
    resp.getBody().getArray().forEach(msg -> System.out.println(msg.toString()));
}

Query documents with Swift.

The GET request has two query parameters: filter to appy a query and pagesize to limit the response to one document.
Here we use the JSONSerialization to parse the response body.

More examples 
import UIKit
import PlaygroundSupport

var urlComponents = URLComponents(string: "https://demo.restheart.org/messages")

// set the query parameters
var queryItems = [URLQueryItem]()
queryItems.append(URLQueryItem(name: "pagesize", value: "1"))
queryItems.append(URLQueryItem(name: "filter", value: "{\"from\":\"Bob\"}"))
urlComponents?.queryItems = queryItems

var urlRequest = URLRequest(url: (urlComponents?.url)!)

// set request method
urlRequest.httpMethod = "GET"

URLSession.shared.dataTask(with: urlRequest) { (data, response, error) in
    guard let dataResponse = data, error == nil
    else {
        print(error?.localizedDescription ?? "Response Error")
        return
    }

    do {
        let jsonResponse = try JSONSerialization.jsonObject(with: dataResponse, options: [])
        print(jsonResponse)
    } catch let jsonError {
        print(jsonError)
    }
}.resume()

// only needed in playground
PlaygroundPage.current.needsIndefiniteExecution = true

Java, Kotlin and JavaScript framework to extend the API

Implement web services in minutes.

Implement a simple interface and deploy the web service by copying its jar file into the plugins directory.

See it on GitHub More examples 
@RegisterPlugin(name = "greetings", description = "just another Hello World")
public class GreeterService implements JsonService {
    @Override
    public void handle(JsonRequest req, JsonResponse res) {
        switch(req.getMethod()) {
            case GET -> res.setContent(object().put("message", "Hello World!"));
            case OPTIONS -> handleOptions(req);
            default -> res.setStatusCode(HttpStatus.SC_METHOD_NOT_ALLOWED);
        }
    }
}

Implement plugins in Kotlin.

You can use Java and Kotlin to implement plugins.

Kotlin Service example 
@RegisterPlugin(name = "kotlinGreeterService", description = "just another Hello World in Kotlin")
class GreeterService : JsonService {
    override fun handle(request: JsonRequest, response: JsonResponse) {
        if (request.isGet) {
            var greetings = JsonObject()
            greetings.addProperty("msg", "Hello World")
            response.content = greetings;
        } else {
            response.statusCode = 400;
        }
    }
}

Snoop and modify requests at different stages of their lifecycle.

This interceptor applies to requests of the hello web service adding a timestamp to the response content.
Interceptor can be executed at different points of the request as defined by the interceptPoint parameter of the annotation RegisterPlugin

More examples 
@RegisterPlugin(name = "helloInterceptor",
    description = "add a timestamp to the response of /greetings",
    interceptPoint = InterceptPoint.RESPONSE)
public class HelloInterceptor implements JsonInterceptor {
    @Override
    public void handle(JsonRequest request, JsonResponse response) {
        response.getContent()
            .getAsJsonObject()
            .addProperty("timestamp", Instant.now().toString());
    }

    @Override
    public boolean resolve(JsonRequest request, JsonResponse response) {
        return request.isHandledBy("greetings");
    }
}

Implement plugins in JavaScript.

This is yet another Hello World web service.
Running RESTHeart on the GraalVM allows you to deploy JavaScript Services and Interceptors.

More examples 
export const options = {
    name: "helloWorldService",
    description: "just another Hello World",
    uri: "/hello"
}

export function handle(request, response) {
    response.setContent(JSON.stringify({ msg: 'Hello World' }));
    response.setContentTypeAsJson();
}
