react-native-bundle-visualizer

See what's inside of your react-native bundle 📦

bundle-visualizer-animation

Uses the awesome source-map-explorer to visualize the output of the Metro bundler.

Purpose

Sometimes, importing a single javascript library can drastically increase your bundle size. This package helps you to identify such a library, so you can keep the bundle size low and loading times fast.

Usage

npx react-native-bundle-visualizer

Or install as a dev-dependency

yarn add --dev react-native-bundle-visualizer

And run it:

yarn run react-native-bundle-visualizer

or when using npm:

npm install --save-dev react-native-bundle-visualizer
./node_modules/.bin/react-native-bundle-visualizer

Command line arguments

All command-line arguments are optional. By default a production build will be created for the ios platform.

Option Description Example
platform Platform to build (default is ios) --platform android
dev Dev or production build (default is false) --dev false
entry-file Entry-file (when omitted tries to auto-resolve it) --entry-file ./index.android.js
bundle-output Output bundle-file (default is tmp) --bundle-output ./myapp.bundle
verbose Dumps additional output to the console (default is false) --verbose
reset-cache Removes cached react-native files (default is false) --reset-cache

Usage with older react-native versions and the Haul bundler

As of react-native-bundle-visualizer version 2.x, the direct output of the Metro bundler is visualized using the source-map-explorer.

Prior to version 2, the Haul bundler was used which used Webpack. If you are having problems visualizing the output for older react-native versions, or you want to explicitly use the Haul bundler, please check out the V1 documentation.
