Question 1

how to measure text width with custom font in react native?

Accepted Answer

Use the `MeasureText.widths` method with options including texts, height, fontSize, and fontFamily. Ensure custom fonts are linked via assets/fonts and package.json rnpm config as per the README.

Question 2

react-native-measure-text vs onLayout: which should I use?

Accepted Answer

Use react-native-measure-text for pre-render calculations without visual layout, ideal for planning. onLayout measures after rendering, which can cause layout shifts but is simpler for post-render adjustments.

Question 3

does react-native-measure-text work with Expo?

Accepted Answer

It likely requires the bare workflow or ejection from Expo, as it involves native module linking not supported in the managed workflow. Check Expo documentation for compatibility with custom native modules.

Question 4

how accurate is react-native-measure-text for different font sizes?

Accepted Answer

It provides accurate measurements based on the native text rendering engine, but accuracy depends on proper font linking and platform-specific configurations, as outlined in the README's custom font section.

Question 5

what are the performance implications of using react-native-measure-text?

Accepted Answer

The promise-based API avoids blocking the UI thread, but frequent async calls might impact performance in heavy-use scenarios. It's best for occasional measurements rather than real-time updates.

Question 6

how to install react-native-measure-text without manual steps?

Accepted Answer

Automatic installation via yarn add and react-native link works for basic setups, but for custom fonts or complex projects, manual editing of native files is often necessary, adding setup overhead.
