Question 1

How do I use Upgrade Helper to upgrade my React Native app?

Accepted Answer

Select your current and target React Native versions on the web tool, review the visual diffs for file changes, use the 'done' buttons to track progress, and apply modifications manually to your codebase. The README includes a YouTube tutorial for guidance.

Question 2

Is Upgrade Helper better than using the React Native CLI for upgrades?

Accepted Answer

Upgrade Helper is superior for visual, manual reviews of changes, especially for complex upgrades, while the React Native CLI may offer automated but less transparent updates. Choose based on whether you prefer detailed oversight or speed.

Question 3

Does Upgrade Helper work with Expo or ejected Expo projects?

Accepted Answer

It primarily targets standard React Native init templates, so for Expo projects, diffs might not cover Expo-specific configurations. Ejected projects could see partial relevance, but custom code may differ.

Question 4

How often are the diffs updated in Upgrade Helper?

Accepted Answer

Diffs depend on the rn-diff-purge project, which updates with new React Native releases. Check that repository for update frequency, as delays could affect accuracy for the latest versions.

Question 5

What if my app has custom code not shown in the diff?

Accepted Answer

You'll need to manually reconcile custom changes, as the tool only shows template-based diffs. Use the diff as a guide but audit your project separately for modifications beyond the standard files.

Question 6

Can I use Upgrade Helper offline or in a private network?

Accepted Answer

No, it's a web-based tool requiring internet access to load diffs and resources. For offline use, you'd need to self-host or rely on local alternatives, which isn't straightforward per the setup.
