3.2.0 (2026-03-18)

• Fixes Your source map refers to generated line 17, but the source only contains 15 line(s).

Bug Fixes

• Fixes @expo/metro-config resolving to old dependencies, causing problems with newer Expo SDK versions (removes this dependency entirely). See the discussion here.

2.3.0 (2021-08-03)

• Fix unknownApp name for Expo apps
• Drop support for Node 10
• Updated dependencies to their latest versions
• Added tests for react-native 0.64 and Expo SDK 42

2.2.1 (2020-07-07)

• Add --expo [bare|managed] option to generate Expo accurate bundles and handle .expo files correctly
• Add --format [html|json|tsv] option to output as json or tsv files (thanks wilau2!)

• Fixed build error when app-name contains special characters (Thanks! @ofiron01)
• Added tests for RN61 and Expo35
• Added CI support through Travis
• Updated all dependencies to their latest versions
• Removed all non-essential files from NPM package

2.0.4 (2019-10-01)

This version switches to using the awesome source-map-explorer package which can visualize the output from the Metro bundler directly. This means that the Haul bundler is no longer used and it should therefore result in less build errors and more accurate results. The source-map-explorer package also provides an interactive User interface which allows you to navigate deeper into the source code. Additionally, you can now run this version directly using npx without having to install any dependencies.

To use, just run npx react-native-bundle-visualizer
