Exact names sort first, then names that start with the query, then other matches, shorter names first. Suggestions come from every source, including ingredient and classification names.
Build a responsive autocomplete
- Wait until the user has typed at least 3 characters.
- Debounce keystrokes by 150 to 250 milliseconds.
- Ignore responses for a query the user has already changed.
- Call your own backend, which adds the key, instead of Medifontis directly.
