Example: Moving up to a few commits to another branch

Branch A has commits (X,Y) that also need to be in Branch B. The cherry-pick operations should be done in the same chronological order that the commits appear in Branch A.

cherry-pick does support a range of commits, but if you have merge commits in that range, it gets really complicated

git checkout branch-B
git cherry-pick X
git cherry-pick Y

NestJS notes

In a larger application, it makes sense to organize your application into multiple modules that split up your code into features and related capabilities.

To define a module, you have to register all of the

• Services that will be instantiated by the Nest.js injector as Providers
• Controllers that will require the Providers as Controllers
• Controllers exported by another module as imports

Providers can be injected into:

Note: for Jest to detect a memory leak and throw an error both arguments are required i.e. detectLeaks and logHeapUsage.
