API Spec Proposal

Hi All!

As discussed I would love to contribute an API spec proposal for the Dapr JS SDK 😃 It’s a bit opiniated, but I hope it might lead to a discussion to see what can be improved.

Some of the key elements:

• Typescript
• Class based
• Extensibility

Usage example:

// Initialize Express
const app = express();

// Initialize dapr service
const daprService = new Dapr("YOUR_URL", "YOUR_PORT");

// State Management
const res = await daprService.state.get("my-store-name", "key");
const res = await daprService.state.save("my-store-name", [{ key: "value" }]);

// Create binding (receive / send)
const res = await daprService.binding.send("my-queue", { hello: "world" });

daprService.binding.receive(app, "my-queue", bindingInput.bind(this));

async function bindingInput(data) {
    console.log("Receive Input");
    console.log(data);
}

// Create Pub Sub
const res = await daprService.pubsub.publish("my-pubsub", "my-topic", { hello: "world" });

daprService.pubsub.receive(app, "my-pubsub", "my-topic", bindingInput.bind(this));

async function bindingInput(data) {
    console.log("Receive Input");
    console.log(data);
}

// Invoke
const res = await daprService.invoke.invoke("app-id", "method-name", { hello: "world" });

await daprService.invoke.register(app, "my-endpoint", invokedEndpoint.bind(this));

async function invokedEndpoint(data) {
    console.log("Receive Input");
    console.log(data);
}

Some of the code I wrote for this can be found here: https://github.com/XavierGeerinck/PublicProjects/tree/master/JS/Dapr/AutoScalingHTTP/Gateway/src/API/dapr this has not been tested yet though… so some work is left to be done.

I have been working on this in a separate repo: https://github.com/Roadwork/dapr-js-sdk I am now waiting for the original maintainers to discuss what to do 😃

Let’s hear from other maintainers before agreeing on that.
