Stacks Auto Imports

Stacks Auto-Import System

Automatically makes functions, models, composables, and utilities available globally without explicit imports.

Key Paths

• Auto-import functions: storage/framework/auto-imports/functions.ts
• Auto-import models: storage/framework/auto-imports/models.ts
• Auto-import index: storage/framework/auto-imports/index.ts
• Auto-import globals: storage/framework/auto-imports/globals.ts
• Global type declarations: storage/framework/auto-imports/globals.d.ts
• Browser manifest: storage/framework/browser-auto-imports.json
• Server manifest: storage/framework/server-auto-imports.json
• Browser type declarations: storage/framework/types/browser-auto-imports.d.ts (~80KB)
• Server type declarations: storage/framework/types/server-auto-imports.d.ts
• General auto-import types: storage/framework/types/auto-imports.d.ts

How Auto-Imports Work

Browser Context (STX Templates)

1. storage/framework/browser-auto-imports.json defines available imports (200+ entries)
2. Types are declared in storage/framework/types/browser-auto-imports.d.ts
3. STX plugin (bun-plugin-stx) resolves imports at build time
4. Available in STX <script> tags without explicit import statements

Browser auto-import injection applies to the STX script entry being compiled. TypeScript modules imported by that script do not inherit its lexical bindings. Every imported module must explicitly import the functions, stores, and types it uses. A generated ambient declaration proves an identifier is available to an STX entry; it does not make that identifier global inside bundled dependencies.

Server Context (Routes, Actions, Jobs)

1. storage/framework/server-auto-imports.json defines server-side imports (100+ entries)
2. Types are declared in storage/framework/types/server-auto-imports.d.ts
3. All 60+ ORM models are auto-imported as globals
4. Available in any server-side TypeScript file

Runtime Injection

storage/framework/auto-imports/globals.ts injects functions into globalThis:

// Makes these available globally without imports:
globalThis.increment = increment
globalThis.count = count
globalThis.isDark = isDark
globalThis.toggleDark = toggleDark
// ... geo functions, GPX functions, etc.

What Gets Auto-Imported

Browser Auto-Imports (200+)

• Composables: useStorage, useLocalStorage, useFetch, useToggle, useCounter, useDark, useNow, etc.
• Utilities: debounce, throttle, retry, sleep, wait, delay, lazy, clamp, rand
• Authentication: useAuth, authGuard, auth
• Formatting: formatCurrency, formatDate, formatNumber, formatDuration
• Browser Query Builder: browserQuery, BrowserQueryBuilder, browserAuth, createBrowserModel
• Payment: confirmCardPayment, confirmPayment, createPaymentMethod, loadCardElement, loadPaymentElement
• Stripe: stripe instance
• Custom Functions: From resources/functions/ (counter, dark mode, GPX, geo utilities)

Server Auto-Imports (100+)

• All ORM Models: User, Post, Author, Product, Order, Payment, Customer, etc. (60+ models)
• Request Models: UserRequest, PostRequest, OrderRequest, etc.
• Actions: Action types and helpers
• Schema: validation schema builder
• Router: route, response helpers
• String Utilities: slug, camelCase, pascalCase, snakeCase, kebabCase, titleCase
• Core: path, storage, log, handleError, Auth, register

Auto-Import Type Declarations

auto-imports.d.ts (general)

declare global {
  const Action: typeof import('@stacksjs/actions').Action
  const response: typeof import('@stacksjs/router').response
  const route: typeof import('@stacksjs/router').route
  const schema: typeof import('@stacksjs/validation').schema
  const slug: typeof import('@stacksjs/strings').slug
  // ... all auto-imported identifiers
}

Adding Custom Auto-Imports

1. Create function in resources/functions/:

// resources/functions/myUtils.ts
export function myHelper() { return 'hello' }

2. Export from storage/framework/auto-imports/functions.ts:

export { myHelper } from '../../resources/functions/myUtils'

3. Declare types in storage/framework/auto-imports/globals.d.ts:

declare function myHelper(): string

4. Inject at runtime in storage/framework/auto-imports/globals.ts:

globalThis.myHelper = myHelper

Generation Commands

buddy generate                  # regenerate all auto-imports
buddy generate --types          # regenerate type declarations
buddy generate --ide-helpers    # regenerate IDE helpers
buddy generate:component-meta   # regenerate component metadata

The build:reset script also regenerates auto-imports.

Server Auto-Import Initialization

import { initiateImports, generateAutoImportFiles, injectGlobalAutoImports } from '@stacksjs/server'

initiateImports()              // initialize auto-import plugin
generateAutoImportFiles()      // generate runtime auto-import files
injectGlobalAutoImports()      // inject models/functions globally

Gotchas

• Browser auto-imports are resolved at BUILD TIME by bun-plugin-stx — not runtime
• Imported browser modules must declare their own imports; STX entry auto-imports do not leak into module scope
• Server auto-imports are injected into globalThis at RUNTIME
• The browser-auto-imports.d.ts file is ~80KB — it's auto-generated, don't edit manually
• Custom functions must be exported from both the function file AND the auto-imports barrel
• Type declarations must match the runtime globals for IDE support
• All 60+ ORM models are auto-imported on the server — available as User.find(1) etc.
• Request models (e.g., UserRequest) are also auto-imported for validated request access
• Auto-imports are regenerated during buddy generate and build:reset
• The discovered-packages.json file at storage/framework/discovered-packages.json is part of this system
