[SAPUI5] Add your own Logout functionality to the Launchpad Sandbox

Use the attachLogoutEvent of the ushell container to trigger your approuter logout endpoint, that needs to be configured in your xs-app.json. The code in my launchpad.html looks like this:

    <script>
        sap.ui.getCore().attachInit(() => {

            sap.ushell.Container.createRenderer('fiori2', true).then(renderer => renderer.placeAt("content"))

            sap.ushell.Container.attachLogoutEvent(e => {
                e.preventDefault()
                window.location.replace('/do/logout')
            }, false)

        })
    </script>

This way, you can reuse the default logout dialog logic the launchpad provides.

For completeness, find also my approuter configuration and custom logout page below.

My xs-app.json:

{
  "welcomeFile": "index.html",
  "authenticationMethod": "route",
  "logout": {
    "logoutEndpoint": "/do/logout",
    "logoutPage": "/logged-out.html"
  },
  "sessionTimeout": 60,
  "routes": [
    {
      "source": "^/logged-out.html$",
      "localDir": ".",
      "authenticationType": "none"
    },
    {
      "source": "^/launchpad.html$",
      "localDir": ".",
      "authenticationType": "xsuaa",
      "cacheControl": "no-cache, no-store, must-revalidate"
    },
    {
      "source": "^/appconfig/(.*)$",
      "localDir": ".",
      "authenticationType": "xsuaa"
    },
    {
      "source": "^/user-api(.*)",
      "target": "$1",
      "service": "sap-approuter-userapi",
      "authenticationType": "xsuaa"
    },
...
  ]
}

My logged-out.html file, placed in the approuter folder next to the launchpad.html:

<!DOCTYPE html>

    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta http-equiv="Content-Type" content="text/html;charset=UTF-8" />

        h2 {

        }
        .centered {
            position: absolute;
            top: 50%;
            left: 50%;
            transform: translate(-50%, -50%);
        }
    </style>
</head>

    <div class="centered">
