How does sentry-react-native pull the list of packages in our app?

[fabiendem]

Hi,

On Sentry, I can see the list of packages used by our app attached to Errors.
Example:

How does Sentry pull this list?
Do we have to add our package.json to the bundle (require("package.json"))?
Or does it read whatever the libraries expose when bundled in the JS payload?

Thank you

Hi @fabiendem,
thanks for the question.

This list is created at build time. All top-level modules which were bundled by Metro are recorded.

The collection script goes thru bundled files and records from what modules a file is.

By default, only modules in ${project_root}/node_modules are recorded.

What do you refer to by our package.json?

Thank you, you've answered my question.

What do you refer to by our package.json?

I mean the package.json of our RN project, the one at the root which declares the dependencies of the project.

🤔 One feature request in the Sentry dashboard would be to be able to search for Issues based on the version of a given package.

Thank you for the suggestion.
