Freddie is Rocket.Chat's Hubot for Federation via

Freddie pairs a Rocket.Chat server with a Synapse Home Server.

From Rocket.Chat:

Rocket.Chat in federated channel

To Home Server:

Synapse in federated room

Out to the rest of the federated world - Slack, IRC, and beyond ... via

NOTE: This project is a work in progress.


npm install --save hubot-freddie

Next, you must edit the external-scripts.json file to load Freddie:


Home Server Application Service Registration

In the node_modules/hubot-freddie directory:

npm install
node src/matrix/genASRegFile.js -r -u <URL of hubot-freddie's incoming webhook>

This will generate a rocketchat-registration.yaml file in the same directory.

Copy this file to both your Rocket.Chat server and Synapse Home Server. Note the absolute path(s).

The format of the generated file is somewhat outdated, please add the following line at the top of the Synapse Home Server's copy:

id: "rocketchat"

On your home server, make sure to add an entry in homeserver.yaml to point to this file:

app_service_config_files: ["/absolute/path/to/rocketchat-registration.yaml"]

You will also need to configure Freddie for your Rocket.Chat server and Synapse Home sever..


You can configure Freddie via environment variables.
