Wiring the Identity Component into the System

To get this working, wire it into the system config:

video-tutorials/src/config.js

// ...
const createIdentityComponent = require('./components/identity') 
function createConfig ({ env }) {
  // ...
  const identityComponent = createIdentityComponent({ messageStore }) 
  const components = [
    identityComponent, 
  ]
  return {
    // ...
    identityComponent, 
  }
}

Line 2 requires the Component’s constructor. Line 5 instantiates the Component, injecting the messageStore dependency. With the Component instantiated, at line 7 we add it to the components array. Adding it to this array is what lets the system know it needs to call the Component’s start function. ...
