DSLink SDK for Dart Slack

DSLink SDK for Dart

Getting Started

Prerequisites

Install

pub global activate -sgit https://github.com/IOT-DSA/broker-dart.git # Globally install the DSA Broker

Start a Broker

dsbroker # If you have the pub global executable path setup.
pub global run dsbroker:broker # If you do not have the pub global executable path setup.

You can edit the server configuration using broker.json. For more information about broker configuration, see this page.

Create a Link

For documentation, see this page. For more examples, see this page.

import "package:dslink/dslink.dart";

LinkProvider link;

main(List<String> args) async {
  // Process the arguments and initializes the default nodes.
  link = new LinkProvider(args, "Simple-", defaultNodes: {
    "Message": {
      r"$type": "string", // The type of the node is a string.
      r"$writable": "write", // This node's value can be set by a responder link.
      "?value": "Hello World" // The default message value.
    }
  });

  // Connect to the broker.
  link.connect();

  // Save the message when it changes.
  link.onValueChange("/Message").listen((_) => link.save());
}

Start a Link

dart path/to/link.dart # Start a link that connects to a broker at http://127.0.0.1:8080/conn
dart path/to/link.dart --broker http://my.broker:8080/conn # Start a link that connects to the specified broker.
