Hi @andrewjack-cat, thanks for reaching out!
This is indeed on our roadmap, we'll let you know once this is available :)
In the meantime, would it still be possible to use the react-native upload command if the release tags were correctly configured?
datadog-ci react-native upload
https://github.com/DataDog/datadog-ci/tree/master/src/commands/react-native#upload
Hi @andrewjack-cat, indeed you should be able to sent the sourcemap with the datadog-ci react-native upload
correctly configured.
As we match errors with sourcemaps based on their version (and with the highest build number), I would recommend to set a specific version for each EAS Update. For instance, if your app is in version 2.1.4
and you are doing the 3rd EAS Update the version could be 2.1.4-eas.v3
.
You will need to set this version when uploading the sourcemap and when initializing the SDK by using the versionSuffix
parameter to eas.v3
(the dash -
will be added automatically by the SDK).
Let me know if this works for you!
I'm having a similar issue with this. The problem right now is not only that expo-updates uses expo export
to generates a HBC file (Hermes Bytecode) which is uploaded, but also the name of the bundle in the code is loaded from a different folder (.expo-internal
) and it uses a hash in the name to manage and track different versions. These 2 factors breaks the mapping between the source code and the source map (since RUM uses bundle_name to do that).
I'm seeing the same issue has @rogerfuentes when using eas updates with the uploaded datadog sourcemaps.
Should the bundle file be renamed before uploading or can the datadog-ci/datadog-expo handle the mapping for eas updates?
@louiszawadzki any updates on this? Source maps don't work at all with expo-updates
or HBC files.
@rogerfuentes I just managed to make everything work as expected. It still involves a workaround that's required while we wait for a proper upstream fix, but I am now able to consume bytecode sourcemaps both for full Expo builds and EAS Updates.
First, the fact that the bundle gets compiled into bytecode is not an issue after all. The bundle doesn't get uploaded to Datadog in the first place, just the sourcemap (see DataDog/datadog-ci#771 ).
Second, the only reason why Datadog fails to consume the sourcemap is the bundle name mismatch - the Expo plugin uses the JS-based bundle names index.android.bundle
and main.jsbundle
, which don't match the reported stack traces for Hermes builds. Note that just the file name seems to matter, the path is ignored.
Fortunately, there are two ways to fix this - there's a difficult way and an easy way:
bundle-$UUID.js
, where the UUID equals the build UUID (? - this might be inaccurate). For EAS updates, it will be a pure hash string without a file extension that can be found in updatesByGroup[0].manifestFragment.launchAsset.bundleKey
in the update metadata.errorEventMapper
that just replaces the reported stack trace file name with a well-known file:const bundleName = Platform.OS === "android" ? "index.android.bundle" : "main.jsbundle"
config.errorEventMapper = (event) => {
event.stacktrace = event.stacktrace.replace(/\(.*:(\d+):(\d+)\)$/gm, `(${bundleName}:$1:$2)`)
return event
}
With this setup, it is now possible to upload additional sourcemaps for EAS updates. Here's a modified version of my script that generates and uploads Android and iOS sourcemaps after publishing an EAS build:
ANDROID_BUNDLE="dist/index.android.bundle"
IOS_BUNDLE="dist/main.jsbundle"
PACKAGE_VERSION="$(jq -r .version package.json)-$EXPO_PUBLIC_UPDATE_VERSION"
mv dist/_expo/static/js/android/*.hbc $ANDROID_BUNDLE
mv dist/_expo/static/js/android/*.hbc.map $ANDROID_BUNDLE.map
mv dist/_expo/static/js/ios/*.hbc $IOS_BUNDLE
mv dist/_expo/static/js/ios/*.hbc.map $IOS_BUNDLE.map
npx datadog-ci react-native upload --platform android --service <redacted> --bundle $ANDROID_BUNDLE --sourcemap $ANDROID_BUNDLE.map --release-version $PACKAGE_VERSION --build-version 1
npx datadog-ci react-native upload --platform ios --service <redacted> --bundle $IOS_BUNDLE --sourcemap $IOS_BUNDLE.map --release-version $PACKAGE_VERSION --build-version 1
Note that EXPO_PUBLIC_UPDATE_VERSION
also needs to be consumed in the Datadog config and therefore must be set before running eas update
:
if (process.env.EXPO_PUBLIC_UPDATE_VERSION) {
config.versionSuffix = process.env.EXPO_PUBLIC_UPDATE_VERSION
}
In my setup, I'm using a combination of the total number of commits (for easier identification) and the current 7-character commit hash, but your mileage may vary.
Addendum:
It turns out that you might not even go through the hassle of renaming the files to a well-known name for EAS updates - after running eas update
, the generated files in dist/_expo/static/js/$PLATFORM/
already have the right hash-based filename (just with the .hbc
extension), so it might in fact work without the errorEventMapper
workaround after all. I'm not sure though if Datadog drops or keeps the .hbc
extension, so it might still be required to remove it before uploading. Note that this only fixes EAS updates, the filename mismatch for full Expo builds still remains.
Thank you @viernullvier, your errorEventMapper
was the key to getting this to work for me. By rewriting the stacktraces, datadog is able to properly match the source maps, and give me the correct location in code that the error occurred in. Much appreciated.
Can someone please help me understand , if we are not using EAS build. We are only using eas update. Do I need to build and upload the sourcemaps manually after a bare-bone build, then also when an eas update happens I have to do the same thing?.
And @viernullvier where would I do the workaround you recommended?, just for eas update or also for the bare-bone build?.
Thanks.
Is your feature request related to a problem? Please describe. I'd like a simple way of uploading sourcemaps to datadog when creating an Expo EAS Update.
Describe the solution you'd like New command in datadog-ci similar to the codepush command - https://github.com/DataDog/datadog-ci/tree/master/src/commands/react-native#codepush
Describe alternatives you've considered Sentry & expo have this available already - https://github.com/getsentry/sentry-react-native/blob/main/scripts/expo-upload-sourcemaps.js
