A small json rest api and websocket server with the main purpose of distributing messages to websocket listerners.

Installation

Usage

As part of another program

In your start script file, run this:

const Logger = require('larvitlog');

const logger = new Logger({
	port: 80,
	fileStoragePath: '/tmp/files',
	intercom, // Instance of larvitamintercom that is used for broadcasting of log messages
	log // Logging object. Will default to a simple console logger if not provided
});

await logger.start();
console.log('Is up and running');

Logging stuff

To send a message that will be broadcast to listening clients post json in the following format to http://address:port/broadcastMessage

{
	"message": "this is the message", // the only mandatory field,
	"emitType": "message", // optional, if only want to broadcast to certain listeners. Will default to "message" if left out
	"metadata": {} // a json object containing what ever. Will be broadcast to clienents.
}

Reading the backlog

It is possible to request allready logged messages from the server. Send a GET request to http://address:port/getMessages and an array of message objects like the example above will be returned.

URL query parameters limit and level can be specified to filter messages, for instance http://address:port/getMessages?limit=100&level=error&level=warn
