Package Guidance

Esta página aún no está disponible en tu idioma.

Shared libraries and hosted backends are in packages/. Application workspaces consume them through workspace dependencies. Package names use the configured scope of the project.

Use bun template add package <name> to restore an available package workspace that setup removed. See Project structure for the full package catalog.

Convex Backend

packages/backend is a hosted backend built with Convex and Better Auth. Application workspaces consume its generated API types and React client as a package workspace. Convex deploys the functions independently.

Use connect-backend to add the client, environment, provider, and optional example connections to a supported application workspace:

Terminal window
bun run generate connect-backend --args mobile convex false false

See Project generators for the supported matrix and generated ownership. The template command does not deploy Convex or create credentials.

Run bun run --filter @init/backend dev to connect the package to a Convex deployment.

Structure

  • src/client/ — React client and auth adapters
  • src/functions/public/ — public queries and mutations
  • src/functions/private/ — admin-only functions
  • src/functions/system/ — operational functions such as health checks
  • src/functions/shared/ — middleware, auth, logging, and environment configuration
  • src/functions/_generated/ — generated API and data-model types

Key-Value Storage

packages/kv provides key-value storage through unstorage. By default, it uses the Redis driver of unstorage.

kv() returns the shared unstorage Storage instance when code first requests it. normalizeKey(...parts) joins key parts with :. namespaceKey(namespace) returns a key helper with the namespace prefix.

Values must be JSON-serializable. The storage returns dates as strings.

To use another backend, change the driver passed to createStorage in packages/kv/src/client.ts.

Native UI

packages/native-ui provides the React Native component library for apps/mobile, built with React Native Reusables (Uniwind variant) and RN Primitives. Components are copy-owned source vendored from the React Native Reusables Uniwind registry and adapted to repository conventions; upstream is a reference, not a dependency.

Import one component per subpath, and the theme through the CSS entry:

import { Button } from "@init/native-ui/components/button"
@import "@init/native-ui/globals.css";

Components

accordion, alert, alert-dialog, aspect-ratio, avatar, badge, button, card, checkbox, collapsible, context-menu, dialog, dropdown-menu, hover-card, icon, input, label, large-title-header, menubar, native-only-animated-view, popover, progress, radio-group, select, separator, skeleton, switch, tabs, text, textarea, toggle, toggle-group, tooltip.

large-title-header is a local component (iOS native large-title header with search bar, plus an Android/web fallback) with no upstream equivalent.

Overlay components (alert-dialog, context-menu, dialog, dropdown-menu, hover-card, menubar, popover, select, tooltip) render through @rn-primitives/portal, so the consuming app must mount a PortalHost near the root (see apps/mobile/src/shared/components/providers.tsx).

Icons use lucide-react-native through the Icon wrapper. Consuming apps that render icons must list lucide-react-native in their own dependencies (as apps/mobile does), since the icon components are imported directly:

import { ArrowRight } from "lucide-react-native"
import { Icon } from "@init/native-ui/components/icon"


;<Icon as={ArrowRight} className="size-4 text-muted-foreground" />

Adding or updating components

The package has a components.json pointing at the React Native Reusables Uniwind registry:

Terminal window
bun run components:add @rnr/<name>   # add or overwrite from the registry
bun run components:diff @rnr/<name>  # inspect upstream changes

After adding a component, re-apply the local conventions: move files from src/components/ui/ up to src/components/, change the cn import to the cn package, and run bun run fix and bun run check from the repository root.

On native, set the placeholder color of a text input with placeholderTextColorClassName and an accent-* class. Uniwind does not apply the placeholder: variant on native.

Upstream review

Component sources are adapted from founded-labs/react-native-reusables (MIT), vendored at commit 119d0b101ff0d18408dc392120e12b5c78ae0c05 (2026-07-02).

To review upstream changes:

  1. Compare the pinned commit with the upstream default branch. Examine only packages/registry/src/uniwind.
  2. For each changed component, run bun run components:diff @rnr/<name> and read the diff. Do not overwrite a file that has local changes; apply the upstream change manually.
  3. Update the pinned commit in the same change.

Do not add an automated updater that overwrites the package.
