Matter implementation on node.js

This project provides a light-weight node.js implementation of a Matter Node: https://github.com/project-chip/connectedhomeip

Install Dependencies

npm install

Build

Because TypeScript is used, the project needs to be built before it can be run.

npm run build

Run

There are three ways to start matternode. The nodenum parameter provides a unique identifier for the matternode process mainly to allocate a unique port number. If nodenum is not passed, it will default to 0. The node will allocate a default port of nodenum + 5540 unless a config file already exists with a manually configured port for the node.

npm start <nodenum>

or

node dist/app.js <nodenum>

or

To build and run:

make run dev <nodenum>

Run tests

To execute all tests and generate a coverage report:

npm test

To execute one test file with full trace level logging:

PINO_LOG_LEVEL=trace npm testone dist/test/message/TestMsgCodec.js

Build Docs

make doc

Usage

$ node src/shell/cli.js 
Network interfaces: [ '::%lo', '::%wlp2s0' ]
store: fabricid = 0000000000000000
store: nodeid = 13671e3e9dd98181

Running multiple instances

matternode uses the node-localstorage package to persistantly store configuration data of each node on disk. In order to run multiple nodes on one machine, start each node with their own nodenum so each will create and use their own .node# directory and use different ports for communication where # is the nodenum passed from the commandline.

# From matternode top-level
npm start 1

# In different terminal
npm start 2

To delete node state, i.e. factory reset, just delete the .node# directory of the node:

rm -fr .node2

The contents of the .node# directory are human-readable, where each field in the key/value store is a separate file in ascii format:

$ ls .node2
encryptionKey	fabricid	ipPort		logLevel	nodeid		nodenum
$ more .node2/nodeid
