Usage example

Thing, Thing Type, Thing Group

import * as iot from "aws-cdk-lib/aws-iot";

const thingType = new iot.ThingType(this, "ThingType", {
  thingTypeName: "example-thingTypeName",
  thingTypeDescription: "example-thingTypeDescription",
  searchableAttributes: ["xxx", "yyy"],
});

const thingGroup = new iot.ThingGroup(this, "ThingGroup", {
  thingGroupName: "example-thingGroupName",
  thingGroupDescription: "example-thingGroupDescription",
  attributes: {
    location: "xxxx",
  },
  mergeAttributes: true,
});

const thing = new iot.Thing(this, "Thing", {
  thingName: "example-thingName",
  attributes: {
    location: "xxxx",
  },
  thingType,
  thingGroup,
});

Add thing to thing group

import * as iot from "aws-cdk-lib/aws-iot";

const thingGroup = new iot.Thing(this, "ThingGroup", {
  thingGroupName: "example-thingGroupName",
});

const thing = new iot.Thing(this, "Thing", {
  thingName: "example-thingName",
});

thing.addToGroup(thingGroup);

Nested Group

import * as iot from "aws-cdk-lib/aws-iot";

const thingGroupL1 = new iot.Thing(this, "ThingGroupLayer1", {
  thingGroupName: "example-thingGroupName",
});

const thingGroupL2 = new iot.Thing(this, "ThingGroupLayer2", {
  thingGroupName: "example-thingGroupName",
  parentGroup: thingGroupL1,
});

Concern

CloudFormation support

CloudFormation don't have ThingGroup and ThingType resource type. So we should create ThingGroup and ThingType L2 constructs with custom resource.

Deleting a ThingType

Deleting a ThingType is a bit difficult. Because when the ThingType is not statue deprecated, it cannot be deleted. And we can delete it 5 minutes after it is deprecated.

[LMtx]

CDK support for the Thing Groups would be very helpful.
