loopback-component-socketio

LoopBack component to use socket.io.

Description

loopback-component-socketio is a package to include socket.io in a loopback application, it was made with the purpose of having certain model under socket.io real time interaction. After installation you will notice two important changes in your application:

• New model created called "geoposition".
• Socket.io server is created when app start.

Enabling the component

In order to use this component you need to enable it as any other component. Edit the file project-dir/server/component-config.json and include it.

{
  "loopback-component-socketio": { 
  }
}

Enabling "geoposition" model

You should have a new model generated after installation of this component, to start using "geoposition" model just enable it as any other model. Edit the file project-dir/server/model-config.json and include it.

{
  "geoposition": {
    "dataSource": "db",
    "public": true
  }
}

Remember to put the datasource of your preference.

Using middleware

This component provides small security check to use socket.io, if your would like to have your socket just for authenticated users then you need to add this option in component declaration. project-dir/server/component.config.json

{
  "loopback-component-socketio": {
    "authMiddleware": "true"
  }
}

Now each connection through your socket.io server needs to include an access_token from a logged user.

let socket = io.connect("http://localhost:3000", {
    query: "accessToken=HJoJKPACAzWk4SRzsYsBzklXzCd2WIWA4TdYyvBgTzO1qCTtIajugh0D44D8lCx4"
});
