RedMetrics2.js

RedMetrics2 (RM2) is a open-source open-data analytics service for online games and research.

This library helps send data from JavaScript applications (in the browser or on the desktop) to the online web service.

Use

1. Install the library. Get it from NPM or clone and build this repository

2. Import or include the library.

Include dependency directly:

<script src="deps/rm2.bundle.js"></script>

Or import it:

import { WriteConnection } from "rm2";

3. Create a connection object

const redmetricsConnection = new rm2.WriteConnection({
  protocol: , // "http" or "https"
  host: , // host of the service
  port: , // optional
  apiKey: , // API key that corresponds to the game
  session: , // optional: information about the player session you would like recorded. Can be updated later
});

4. Connect (async)

redmetricsConnection
  .connect()
  .then(function () {
    console.log("Connected to RM2");
  })
  .catch(function () {
    console.error("Problem connecting");
  });

5. Send events

redmetricsConnection.postEvent({
  type: , // event name
  customData: { }, // optional
});

6. Optionally, update the session in progress

redmetricsConnection.updateSession({
  externalId: ,
  customData: ,
});

Upgrading from RedMetrics v1 (RM1)

To upgrade from RM1, do the following:

1. Include or import the new file (rm2.bundle.js)
2. Update the connection information to include API key instead of the "game version"
3. redmetrics.prepareWriteConnection() becomes new rm2.WriteConnection()
4. Change references from player to session

• playerId => sessionId
• updatePlayer() => updateSession()
