Dev mode

“Staging without staging”

Burt can put your script in what we call “dev mode”. If the script is in dev mode, two things can happen:

1. If the cookie burt-inject has a value, the tracking will work just as expected.
2. If the cookie burt-inject is not present, the script will not start.

The purpose of dev mode is that the script can be deployed to the site without affecting any visitor (because they do not have the burt-inject cookie set). This also allows a developer to work with the script in the real environment without affecting any visitor.

Push blocks

The dev mode script requires all integration code to be wrapped in push-blocks. That means that instead of this:

window.burtApi.startTracking(function(api) {
  // ...
});

The integration code should be wrapped with a push block, like this:

window.burtApi = window.burtApi || [];
window.burtApi.push(function() {
  window.burtApi.startTracking(function(api) {
    // ...
  });
});

There can be any number of push blocks on the site.

The inject cookie

To activate the burt script, give the cookie burt-inject a value:

document.cookie = 'burt-inject=1';

To deactivate it, remove the cookie value:

document.cookie = 'burt-inject=';
