@project-chip/matter.js

matter.js

Implementation of Matter protocol in typescript with no native dependencies (and very limited dependencies).

This is the JavaScript only Core of the Matter protocol. It is used by other projects to implement Matter Nodes and Clients and add the relevant specific implementations for Network and other elements.

The following features are abstracted away to allow to be implemented environment specific:

• Network (UDP/MDNS)
• Crypto (to be split out)
• Storage
• Date/Timer
• Logger (Default uses "console")

Exported functionality

This library exports the Matter protocol functionality as well as some helper functions as named exports:

Export	Description
@project-chip/matter.js	Exports the current (legacy!) low level API to implement a Device or a Controller. This will be replaced soon by the new High Level API!
@project-chip/matter.js/certificate	Exports Certificate (Root-/PAA/PAI/IAC/DA-Certificates) related functionality
@project-chip/matter.js/cluster	Exports Matter Cluster definitions and Default Cluster-Handlers
@project-chip/matter.js/codec	Exports Codecs for e.g. Matter-Messages
@project-chip/matter.js/common	Exports certain common functionalities
@project-chip/matter.js/crypto	Exports Crypto related abstract functionality that needs to be implemented platform specific!
@project-chip/matter.js/datatype	Exports Matter Data types
@project-chip/matter.js/fabric	Exports Matter-Fabric functionality
@project-chip/matter.js/interaction	Exports Matter Interaction protocol functionality
@project-chip/matter.js/log	Exports Logging functionality (based on "console")
@project-chip/matter.js/math	Exports Math functionality used by Matter
@project-chip/matter.js/mdns	Exports Basic MDNS functionality (uses Network implementation)
@project-chip/matter.js/net	Exports Basic Network abstract functionality that needs to be implemented platform specific!
@project-chip/matter.js/protocol	Exports Basic Matter protocol functionality
@project-chip/matter.js/schema	Exports Schema definitions and functionality
@project-chip/matter.js/securechannel	Exports Secure Channel functionality
@project-chip/matter.js/session	Exports Session and Secure-Session functionality
@project-chip/matter.js/spec	Exports Matter Specification References
@project-chip/matter.js/storage	Exports Basic Storage abstract functionality that needs to be implemented platform specific!
@project-chip/matter.js/time	Exports Basic Time/Timer abstract functionality that needs to be implemented platform specific!
@project-chip/matter.js/tlv	Exports Matter TLV type definitions
@project-chip/matter.js/util	Exports Basic Utility functionality

Both exports and the typings are exported as CommonJS and ES6 modules.

For more details please refer to the API Documentation.

Typescript note

To have Typescript and your IDE know all the relevant exported functionality you need to use the following in your tsconfig.json:

{
    "compilerOptions": {
        "moduleResolution": "node16", // Required to support package.json exports
        "module": "node16" // Required to make sure all imports are js
    }
}

matter.js usage

matter.js is used at the core of those two projects:

• matternode: a light-weight node.js implementation of a Matter Node
• matter-node.js: a Matter client / server running on node.js compatible with HA (Android / iOs support in progress)

Building

• npm run build: Build all code and create CommonJS and ES6 variants in dist directory. This will built incrementally and only build the changed files.
• npm run build-clean: Clean the dist directory and build all code from scratch

Tests

• npm run test-node: Run tests in node.js
• npm run test-web: Run tests in the browser
• npm run test: Run all tests

test-web will create a /coverage directory containing the test code coverage
