Hot reload

Meaning in mobile app development, with examples

nounCommon term

In mobile app development, hot reload means: A development feature that shows code changes in the running app within a second or two, usually without losing the current screen or its state.

In Turkish: anında yeniden yükleme, hot reload

How it is used

Best known from Flutter, where it is contrasted with hot restart, which resets the app's state. React Native's version is called Fast Refresh, while SwiftUI and Jetpack Compose offer live previews. Developers say a change 'didn't hot reload' when it needs a full rebuild.

Example sentences

  1. With hot reload, the designer can see color changes on the phone almost immediately.

  2. Hot reload doesn't pick up changes in the main function, so do a hot restart.
