Moving Forward Without a Backend

One challenge during a short project is that frontend and backend development rarely progress at exactly the same speed. Waiting for every API to be completed can quickly turn into lost development time.

During Officener, I needed to work on reply editing and deletion while the corresponding backend functionality was not yet available. Instead of leaving those interactions unfinished, I used Mock Service Worker to simulate the API behavior.

I created mock handlers for the expected requests and responses, which allowed the frontend to behave as though it were communicating with a real server. I could build the interaction, handle different states, and add toast feedback for user actions.

The value of mocking was not just speed. It forced me to think about the API contract earlier: what information should be sent, what should come back, and what the interface should do when something succeeds or fails.

Once I understood that, MSW stopped feeling like a temporary workaround. It became a useful way to separate frontend progress from backend availability while still designing around realistic server behavior.
