Custom express handlers

It looks like custom express handlers can be injected to the backend-application

I am not sure how to do that. Is there any example demoing this usage?

Hi @jeluard, BackendApplicationContirubion.configure application lifecycle hooks should be used to participate in configuration of the express application: https://github.com/eclipse-theia/theia/blob/3ddb313f4597bcecd05563309a6c1c9814a90895/packages/core/src/node/backend-application.ts#L34
