Updating Dependencies
Packages to NEVER update with this skill
These are pinned to the Expo SDK version — do not touch:
react, react-dom, react-is, react-test-renderer — must match Expo SDKreact-native — must stay on the minor version Expo SDK expects (e.g., Expo 56 → react-native 0.85.x). Do NOT update across minor versions.@react-native/babel-preset, @react-native/eslint-config, @react-native/metro-config — must match the react-native version (e.g., react-native 0.85.x → these stay at 0.85.x). Do NOT update across minor versions.
expo and expo-* packages can be updated, but update them all together in one pass since they are versioned in sync.
Process
1. Check what's outdated
Run the following script from shared/ — it checks all packages and derives pre-release vs stable from each package's current version automatically (no manual list to maintain):
cd shared && python3 ../.claude/skills/update-dependencies/check-outdated.py
The script never suggests a downgrade. For packages currently on a stable version it finds the highest stable version. For packages currently on a pre-release version it finds the highest semver on the same major — which handles both newer pre-releases and graduation to stable (e.g. 56.0.0-preview.x → 56.0.5).
When the highest stable version is on a newer major than the current one, the script also reports the highest version reachable within the current major as a separate (in-major) line, with the major jump flagged below it:
@babel/core: 7.29.7 -> 7.30.0 (in-major)
↳ MAJOR jump available: -> 8.0.1 (major 7 -> 8)
Take the (in-major) bump as the safe routine upgrade; treat the ↳ MAJOR jump as an opt-in decision (peer-dep checks, app build to verify). If no in-major upgrade exists (already on the latest minor/patch of the current major), only the single cur -> latest line prints — the jump to the next major is then the only available upgrade.
Note on eslint-plugin-react-compiler rc versions: npm may have rc.1-hash variants that sort after rc.2 alphabetically but are older. Verify manually if the script suggests downgrading to a hash-tagged rc.
3. Edit package.json with exact versions
- Use exact versions only — no
^ or ~
- Edit
shared/package.json directly
- Update only the packages you intend to change
- Verify no
^ or ~ are present before saving
4. Install and validate
cd shared && yarn
yarn lint
yarn tsc
yarn ios:pod:install
Lint/tsc failures after a dep update are caused by the update — do not try to prove they are pre-existing. The branch is clean before the update starts, so any new errors are ours to fix. Fix them before proceeding. If the failures are large or unclear, stop and ask for guidance rather than guessing.
4a. Check for duplicate package installs
After yarn, run:
cd shared && python3 ../.claude/skills/update-dependencies/check-dupes.py
This finds packages where a nested node_modules contains a newer version than what's installed at the top level — the case where bumping our pin in package.json would let yarn deduplicate. It ignores nested installs that are older (locked by their parent packages, not fixable by bumping our pins).
If duplicates are found: Update the version in package.json to the suggested version, then re-run yarn.
Why this matters: Packages that use React.createContext() or other module-level singletons break silently when installed twice — the provider uses one instance and the consumer reads a different one. Classic symptom: "Couldn't determine focus state. Is your component inside a screen in a navigator?" (useIsFocused from @react-navigation/core).
4b. Security audit
After yarn, run:
cd shared && python3 ../.claude/skills/update-dependencies/check-audit.py
This runs yarn audit --json, dedupes the advisories, and cross-references yarn.lock to suggest the cheapest fix for each one:
- DIRECT — the vulnerable package is in our
package.json. Bump it there (exact version), run yarn.
- LOCKFILE — transitive, and the patched version satisfies every range that requires it. Delete the listed entry block(s) from
yarn.lock (the entry key line plus its indented lines), then run yarn — it re-resolves to the patched version with no package.json change.
- RESOLUTION — transitive, but the patched version is outside the range the parent accepts. Bumping the direct dependency that pulls it in (first segment of the
via: path) is the better fix when possible — but if you already brought direct deps current in steps 1–4, a still-flagged advisory means no released parent fixes it yet (confirm with npm view <parent> dependencies only if you skipped updating that parent). Then add the suggested resolutions entry. Prefer scoping it to the vulnerable parent (e.g. "xcode/uuid") over a blanket "**/uuid" when some installed copies are already on a safe version — forcing a major-version jump on every consumer risks breaking ones that were fine. If ALL installed versions are vulnerable (the installed: line lists every copy), a blanket **/ resolution is correct and covers them all with one entry. If multiple advisories suggest different versions for the same module, add ONE resolution entry with the highest version.
- NO-FIX — no patched version published. Don't work around it; report it to the user with the advisory link.
After applying fixes: re-run yarn, re-run this script to confirm clean, and re-run the dupes check (4a) — resolutions can change the dedupe picture. A forced major bump via resolutions runs code the parent package never tested with. "Verify" means: yarn lint + yarn tsc always; if the forced package sits under runtime app code, also build/run the app; if it sits under tooling (test runners, bundler, patch-package), run that tool once if cheap. Either way, explicitly tell the user which packages were force-bumped so they can watch for fallout.
5. Evaluate existing patches
After yarn, check whether any patches/*.patch files target a package you just updated — the filename encodes the version (e.g. @legendapp+list+3.0.0-beta.56.patch). For each such patch:
- Run
yarn patch-package to see if it applies cleanly.
- If it fails: the patch still addresses a real issue, but the upstream source has moved. Fix the source files in
node_modules directly (re-apply the intent of the patch), then run yarn patch-package <package> to regenerate it. Delete the old patch file.
- If it applies: check whether the fix was merged upstream by searching the updated source for the patched code. If the upstream already has the fix, delete the patch file.
Never rename patch files or hand-edit the .patch file itself. Let patch-package generate the correctly-named file from your source edits.
6. If updating electron
After bumping the electron version in package.json and running yarn, update the download hashes:
cd shared && ./desktop/extract-electron-shasums.sh <new-version>
This regenerates shared/desktop/electron-sums.mts with the correct SHA256 checksums for all platforms.
Notes
lodash types (@types/lodash, @types/lodash-es) can be updated independently of lodash itself.- Always bump
@types/react to the latest patch the script finds, even if runtime react is unchanged. DefinitelyTyped ships type-only patches independent of the react runtime version. When you bump it, update the resolutions entry (**/@types/react) to the SAME version — multiple installed copies of @types/react cause type conflicts.
@types/react-dom, @types/react-is should stay in sync with their runtime counterparts — update only if the runtime version changed.- Packages with versions matching the
expo SDK pattern (e.g., 56.x.x) are expo-* packages and can be updated together.
@react-navigation/core must track what @react-navigation/native actually resolves, not just the surface number of the other nav packages. @react-navigation/native (alpha.24) and @react-navigation/core (alpha.15/alpha.16) use different numbering — they are NOT in sync by design. Always check-outdated on @react-navigation/core and accept upgrades the script finds, even if the number looks unrelated to the other nav alpha versions. Skipping this causes duplicate installs and React context identity mismatches at runtime.
