Build is a DietlyAPI developer guide for a calorie-tracker web app. It describes how to make a single-page tracker that combines food search, a daily log, and per-serving calorie calculations. The guide presents the result as a usable tracker that runs in the browser and keeps its state across refreshes with localStorage.
The sample app uses one HTML file and a client-side flow with no server and no build step. A search box calls GET /search as the user types, with a minimum of two characters and debounce behavior to avoid one request per keystroke. Search results show the food name, brand, and per-100 g calories. Tapping a result adds it to today’s log with an editable gram amount, and a running total sums the entries using the same calculation. The guide also notes that the read endpoint is public, so the app does not expose a privileged key.
The page is framed as a developer guide for building the tracker end to end, then extending it after real use begins. Its audience is developers building a calorie-tracker web app or similar nutrition-tracking tool. It also does not describe any deployment target other than the browser-based, client-side page shown in the guide.
