LwM2M TypeScript type definitions and JSON schema

TypeScript type definitions and JSON schema for the objects defined in the LwM2M Object Registry.

This is useful if you need to validate a JSON representation of those objects.

Installation

npm ci
// Clone LwM2M object registry
git clone https://github.com/OpenMobileAlliance/lwm2m-registry.git --depth 1
npm test

Usage

See example.ts

JSON document structure

LwM2M values are encoded as a JSON document, where the key is an extended version of the LwM2M URN: <ObjectID>:<ObjectVersion>@<LwM2MVersion> (where ObjectVersion and/or LwM2MVersion can be omitted if it is 1.0).

Example
