Main controller
Contents
Handle application lifecycle events via the main controller.
main.js
Enonic apps may contain a special controller known as the Application controller, or just "main.js". Simply place the file src/main/resources/main.js into your project.
main.js gets invoked when an application lifecycle event occurs. A common use of this controller is initialization like creating repositories, and registration of event listeners when the application starts.
The main.js execution should complete as quickly as possible to prevent application stalling. Never call remote endpoints or wait in loops for events inside main.js global scope.
| If you need to perform time consuming work in the main controller, consider implementing it as a task. |
Running code when the application starts:
main.js
// Log application start
log.info('Application ' + app.name + ' started');Running code when the application stops:
main.js
// Log application stop
__.disposer(function() {
log.info('Application ' + app.name + ' stopped');
});
