Updating @quilibrium/quorum-shared

This skill guides small additions to the quorum-shared package — a new icon, a new type, a new hook, a new util — typically to support a feature being built in quorum-desktop.

For larger moves — relocating existing code from desktop to shared, deleting the local source, updating consumer imports — use the migrate-to-shared skill instead. That workflow has six phases (analyze, prepare, copy, update desktop, verify, commit) and handles @lingui stripping, DOM-API guards, ESM/Metro fallbacks, and partial migrations.

For tracking ongoing migrations, see .agents/tasks/quorum-shared-migration/README.md in this repo — that's the master tracker for what's done, in progress, ready, and blocked.

Locate the Shared Repo

The shared package is linked locally via package.json:

"@quilibrium/quorum-shared": "link:../quorum-shared"

The conventional sibling path is d:/GitHub/Quilibrium/quorum-shared (Windows) or /mnt/data/GitHub/Quilibrium/quorum-shared (Fedora). If that path doesn't exist, ask the user where quorum-shared is located rather than trying to resolve via node -e (Windows quoting makes that brittle).

Workflow

1. Branch

Create or switch to a feature branch in quorum-shared. Use generic names when batching related changes (e.g., feat/dm-receipts-shared), or specific names for one-off additions.

cd <shared-repo-path>
git checkout -b <branch-name>

2. Make Changes

The source lives in src/. Key locations:

What to add	Where
Icons	src/primitives/Icon/types.ts (IconName union) + src/primitives/Icon/iconMapping.ts (icon map). Icons use Tabler Icons — the map value is the Tabler component name (e.g., checks: 'IconChecks').
Primitive components	src/primitives/<ComponentName>/ — web (.tsx), native (.native.tsx), types, styles
Types	src/types/ — shared TypeScript types
Hooks	src/hooks/ — shared React hooks (cross-platform-safe ones only; most hooks remain blocked on the hooks migration)
Utils	src/utils/ — shared utility functions
API/transport	src/api/, src/transport/
Storage adapters	src/storage/ — StorageAdapter interface and implementations
Crypto	src/crypto/ — WasmCryptoProvider and crypto helpers
Signing	src/signing/
Sync protocol	src/sync/ — SyncService (precedent for shared service classes)
Feature services (new convention)	src/<feature>/ — e.g. src/sync/, planned src/typing/, planned src/receipts/. Each folder holds service.ts, service.test.ts, index.ts barrel.

All public exports must be re-exported from src/index.ts.

3. Build

Both steps are required — tsup bundles the code, tsc generates type declarations. The shared package has a build script that runs both:

cd <shared-repo-path>
yarn build

(Equivalent to tsup && tsc --project tsconfig.build.json directly — see quorum-shared/package.json.)

This produces three bundles in dist/:

• index.mjs — ESM (web, consumed by Vite)
• index.js — CJS (web)
• index.native.js — CJS (React Native, consumed by Metro)

Note: dist/ is gitignored — only commit source files.

4. Verify

Since this project uses link:../quorum-shared, the rebuilt dist/ is picked up immediately — no install step needed. Verify in the consuming repo:

# Check the export exists in the built output
grep '<your-addition>' <shared-repo-path>/dist/index.mjs

# If Vite dev server is running, it should hot-reload automatically

5. Commit

In quorum-shared — commit source files only (dist is gitignored):

cd <shared-repo-path>
git add src/
git commit -m "feat: <describe what was added>"

Then in this repo — update the consuming code and commit:

cd <this-repo-path>
git add <changed-files>
git commit -m "feat: <describe how the shared addition is used>"

Common Patterns

Adding an icon

1. Find the Tabler icon name at https://tabler.io/icons
2. Add to src/primitives/Icon/types.ts — add 'icon-name' to the IconName union in the appropriate category
3. Add to src/primitives/Icon/iconMapping.ts — add 'icon-name': 'IconTablerName' to the map in the same category
4. Build, verify with grep, then use <Icon name="icon-name"> in the consuming repo

Moving types from local to shared

When a feature stabilizes and its types should be shared:

1. Copy the type definitions to src/types/
2. Re-export from src/index.ts
3. Build
4. Update imports in consuming repo from local path to @quilibrium/quorum-shared
5. Delete the local type file

Adding a hook

1. Create src/hooks/useMyHook.ts
2. Export from src/hooks/index.ts
3. Re-export from src/index.ts
4. Build
5. In the consuming repo, import: import { useMyHook } from '@quilibrium/quorum-shared'

Important: most desktop hooks are NOT shareable yet — the hooks migration is blocked on mobile codebase access (see .agents/tasks/quorum-shared-migration/designs/2026-03-19-hooks-design.md). Only add a hook to shared if it has zero context dependencies (no useMessageDB, no usePasskeysContext, etc.) and zero DOM coupling.

Adding a util

1. Create src/utils/myUtil.ts (or extend an existing file)
2. Export from src/utils/index.ts
3. Re-export from src/index.ts
4. Build
5. Import in desktop: import { myUtil } from '@quilibrium/quorum-shared'

If the util has its own test, co-locate it as src/utils/myUtil.test.ts (matching the existing sync/service.test.ts precedent). Don't put tests in src/dev/tests/ — that's a desktop convention.

Adding a service (feature folder)

For a service class with its own protocol logic (typing, receipts, future ones):

1. Create the feature folder: src/<feature>/service.ts, src/<feature>/service.test.ts, src/<feature>/index.ts
2. Service constructor takes all platform-specific pieces as callbacks (the SyncService pattern). No direct imports of DOM, storage, crypto, or React.
3. Re-export the service class and its options interface from the feature's index.ts
4. Re-export from src/index.ts
5. Build, run yarn test:run in shared to verify the colocated test passes

If you're migrating an existing desktop service (rather than building one fresh), use the migrate-to-shared skill — it covers the deletion step and consumer-import updates that this skill omits.

Adding a colocated test

The shared package uses Vitest. Tests live alongside their source (src/sync/service.test.ts, src/utils/myUtil.test.ts). To verify:

cd <shared-repo-path>
yarn test:run

No separate test-imports list to maintain — Vitest picks up *.test.ts files automatically.
