• Authenticator SDK - : to perform user management tasks such as authentication and password recovery.

• Storage SDK - : to operate on data sent by devices.

Quickstart

Install

npm install --save @cesarbr/knot-cloud-sdk-js

AMQP SDK: Creating a new thing

const { Client } = require("@cesarbr/knot-cloud-sdk-js");

const config = {
  amqp: {
    hostname: "broker.knot.cloud",
    port: 5672,
    username: "knot",
    password: "knot",
    token: "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...", // this is not a valid token!
  },
  http: {
    hostname: "api.knot.cloud", // API Gateway address
    port: 80,
    protocol: "http",
  },
};

const thing = {
  id: "abcdef1234567890",
  name: "my-thing",
};

const main = async () => {
  try {
    await client.connect();
    await client.register(thing.id, thing.name);
    console.log("thing successfully created");
    await client.close();
  } catch (err) {
    console.error(err);
  }
};

main();

Authenticator: Creating a new user

const { Authenticator } = require("@cesarbr/knot-cloud-sdk-js");

const client = new Authenticator({
  protocol: "https",
  hostname: "api.knot.cloud",
});

async function main() {
  try {
    await client.createUser("user@provider.com", "123qwe!@#QWE");
  } catch (err) {
    if (err.response) {
      console.error(err.response.data.message);
      return;
    }
    console.error(err);
  }
}

main();

Storage: Receiving user's data

const { Storage } = require("@cesarbr/knot-cloud-sdk-js");

const client = new Storage({
  protocol: "https",
  hostname: "data.knot.cloud",
  token: "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...", // this is not a valid token!
});

async function main() {
  try {
    console.log(await client.listData());
  } catch (err) {
    if (err.response) {
      console.error(err.response.data.message);
      return;
    }
    console.error(err);
  }
}
