One way is to run this in your project's root directory:
react-native bundle \
--dev false \
--platform ios \
--entry-file index.js \
--bundle-output deleteme.jsbundle \
--sourcemap-output index.map
Press enter, and go grab a cup of coffee.
Some notes:
--dev false
ensures you cut a production build. metro
will shake out unneeded imports and remove if (__DEV__)
chunks o' code--platform ios
has a android
option too--entry-file index.js
is the default entry point... if you've changed this manually you'll know--bundle-output
is the giant js file that gets embedded in your app ... for straight up source map output (like what you're asking for), this is a byproduct you can delete (hence the name)--source-output
finally what you're looking for!! heads up, there are different maps for ios and android (exactly why, i'm not sure), so mind the file name so you don't clobber yourself.
Hi there! I need a way to extract source maps for production build. To have good crash reporting. What is the right way to do it?
