Dev Server Architecture

Unified Dev Server (buddy dev with no arguments)

When buddy dev runs without a specific server flag, startDevelopmentServer() in dev.ts:

1. Reads config/app.ts devLaunch; native opens appPath in Craft, while browser keeps the browser default
2. Reads port configuration from env vars (PORT, PORT_API, PORT_DOCS, PORT_ADMIN)
3. Detects custom domain from APP_URL (e.g., stacks.localhost)
4. Prints Vite-style banner with URLs for Frontend, API, Docs, Dashboard
5. Sets STACKS_PROXY_MANAGED=1 to prevent subprocesses from starting their own proxies
6. Starts all servers in parallel via Promise.all():
   • runFrontendDevServer() -- STX template server on port 3000
   • runApiDevServer() -- bun-router API on port 3008
   • runDocsDevServer() -- bunpress docs on port 3006
   • runDashboardDevServer() -- STX + Craft native window on port 3002
   • startReverseProxy() -- rpx HTTPS proxy on port 443 (only if custom domain set)
7. Registers SIGINT/SIGTERM handlers that SIGKILL the entire process group

Action Execution (runAction in helpers/utils.ts)

• Dev actions (paths starting with dev/) automatically get --watch flag via bun --watch
• The dev/views action is special-cased for maximum performance: imports bun-plugin-stx/serve directly instead of spawning a subprocess
• NODE_PATH is set to include pantry/ so compiled pantry packages can resolve @stacksjs/* at runtime
• Dev action subprocess output is suppressed by default (quiet mode), visible with --verbose

Frontend Dev Server (views.ts)

Uses bun-plugin-stx serve function with pattern-based view resolution:

• User views: resources/views (checked first)
• Default views: storage/framework/defaults/resources/views (fallback)
• User layouts: resources/layouts
• Default layouts: storage/framework/defaults/resources/layouts
• Components: storage/framework/defaults/resources/components/Dashboard

API Dev Server (api.ts)

• Uses @stacksjs/router with CORS middleware
• Calls route.importRoutes() to load route definitions
• Serves on 127.0.0.1 at config.ports.api (default 3008)

Dashboard Dev Server (dashboard.ts)

• Starts the STX server on config.ports.admin and optionally opens a native Craft window
• Mounts the config API on the same dashboard origin under /api/config/*
• Config routes list, read, expose source for, and atomically update config/*.ts files
• Config updates support top-level scalar literals only and preserve comments and environment-backed expressions
• Discovers ORM models from app/Models/ and storage/framework/defaults/app/Models/
• Writes .discovered-models.json manifest for sidebar population
• Preloads ORM model globals for server scripts, while framework server helpers use explicit imports
• Leaves resources/functions to the STX client auto-import pipeline because browser helpers may depend on signals and other browser-only primitives
• Opens a Craft createApp() window when a supported SDK and native binary are available (1400x900, titlebar hidden)
• Builds the web sidebar from configured sections and discovered model dashboard metadata

Docs Dev Server (docs.ts)

• Uses @stacksjs/bunpress with { watch: true, quiet: true }
• Serves from docs/ directory on port 3006

Reverse Proxy & HTTPS

When APP_URL is set to a custom domain (not localhost):

• startReverseProxy() uses @stacksjs/rpx to proxy all subdomains through HTTPS on port 443
• Proxy mapping: localhost:3000 -> domain, localhost:3008 -> api.domain, localhost:3006 -> docs.domain, localhost:3002 -> dashboard.domain
• SSL certs stored in ~/.stacks/ssl/ with 825-day validity
• Individual dev servers check STACKS_PROXY_MANAGED to avoid starting duplicate proxies

SSL Setup (setup/ssl.ts)

• setupSSL(options) -- Complete SSL setup: hosts file + cert generation + trust
• generateCertificates(domain) -- Uses @stacksjs/tlsx to create Root CA + host cert
• addDomainToHosts(domain) -- Adds 127.0.0.1 <domain> to /etc/hosts (requires sudo)
• trustCertificate(domain) -- Adds cert to macOS Keychain or Linux ca-certificates
• Supports non-interactive mode via SUDO_PASSWORD env var
• Cert files: ~/.stacks/ssl/<domain>.crt, <domain>.key, <domain>.ca.crt

Hot Reload / Watch Mode

• Dev actions use bun --watch: All actions with paths starting with dev/ are automatically run with Bun's --watch flag, which restarts the process on file changes
• Frontend (STX): bun-plugin-stx/serve has its own built-in watch/HMR for .stx templates
• API server: Runs via bun --watch, restarts on route or handler changes
• Docs: @stacksjs/bunpress runs with watch: true for live documentation updates
• Components: Delegates to the component library's own bun run dev (typically Vite-based HMR)

Preloader (preloader.ts)

Configured in bunfig.toml as preload = ["./storage/framework/defaults/resources/plugins/preloader.ts"].

Execution Phases

1. Fast command skip: Commands like dev, build, test, lint, --version, --help skip the preloader entirely for maximum startup speed
2. Environment detection: Deploy/production commands (deploy, cloud:remove, etc.) set APP_ENV and NODE_ENV before loading env files
3. Env loading: Calls autoLoadEnv({ quiet: true }) from @stacksjs/env for encrypted .env file support
4. Auto-imports (non-fast commands only):
   • Loads 21 @stacksjs/* packages into globalThis (actions, router, orm, validation, etc.)
   • Loads all functions from resources/functions/**/*.ts
   • Loads all ORM model instances into globalThis (priority: user > framework > defaults)
   • Loads all Job instances from app/Jobs/ into globalThis
   • Loads all Controller classes into globalThis
   • Runs discoverPackages() for package auto-discovery
5. Protected globals: 80+ built-in names (process, console, Buffer, fetch, Bun, etc.) are never overwritten

bunfig.toml Configuration

preload = ["./storage/framework/defaults/resources/plugins/preloader.ts"]

[test]
preload = ["./tests/setup.ts"]
coverage = true

[run]
bun = true  # equivalent to `bun --bun` for all `bun run` commands

[serve.static]
plugins = ["bun-plugin-stx"]  # STX template engine plugin for Bun.serve

[install]
registry = { url = "https://registry.npmjs.org/", token = "$BUN_AUTH_TOKEN" }
linker = "hoisted"

Production Server (server/src/index.ts)

• Queue worker mode: When QUEUE_WORKER env var is set, imports and runs the job from app/Jobs/<JOB>.ts with retry support (configurable via JOB_RETRIES, JOB_BACKOFF_FACTOR, JOB_INITIAL_DELAY, JOB_JITTER)
• HTTP server: Bun.serve() on PORT (default 3000), delegates to serverResponse() from @stacksjs/router
• WebSocket: Built-in WebSocket upgrade support (open/message/close handlers as stubs)
• Development mode: Auto-enabled when APP_ENV is not production or prod
• Docker: Multi-stage build with oven/bun:1.3.10, runs as non-root bun user, exposes port 3000, includes curl for healthchecks

Server Build Process (server/build.ts)

1. Stops any running stacks-server Docker container
2. Cleans previous build artifacts (app/, config/, dist/, docs/, storage/)
3. Builds server entry (src/index.ts) to dist/ using Bun.build (ESM, target: bun)
4. Builds all app/**/*.{ts,js} files to server/app/ (ESM, no splitting, external: @swc/wasm)
5. Post-processes built files: rewrites storage/framework/server imports to dist/
6. Strips export { ENV_KEY, ENV_SECRET, fromEnv } from dist (bundler workaround)
7. Copies custom server config if present (server/ dir at project root)
8. Optionally builds Docker image if cloud.api.deploy is enabled

Doctor Health Checks

buddy doctor verifies:

• Bun runtime version (pass if v1.0+, warn otherwise, fail if missing)
• Node.js version (pass if v18+, warn otherwise)
• package.json existence and project name
• .env file presence (warn if missing, not a failure)
• APP_KEY is set (warn if not, suggests buddy key:generate)

STX Configuration (config/ui.ts)

{
  componentsDir: 'components',
  layoutsDir: 'layouts',
  partialsDir: 'partials',
}

Note: Dashboard mode overrides these settings via its own serve() options.

Gotchas

• The @stacksjs/development package is currently a stub (export {}) -- all actual dev tooling lives in the actions and server packages
• The preloader skips entirely for dev, build, test, lint, and version/help commands -- auto-imports are NOT available in those contexts
• buddy dev (no arguments) starts ALL servers simultaneously -- use buddy dev api or buddy dev frontend to start only one
• The STACKS_PROXY_MANAGED=1 env var prevents individual dev servers from starting their own reverse proxy -- only the unified buddy dev command manages the proxy
• Dev actions are executed with bun --watch automatically -- do NOT add --watch manually or you get double-restart behavior
• The dev/views action is special-cased in runAction() to run in-process (no subprocess) for performance -- other dev actions spawn subprocesses
• NODE_PATH is injected to include pantry/ directory so compiled pantry packages can resolve @stacksjs/* dependencies at runtime
• The dashboard config API shares the dashboard origin and atomically modifies top-level scalar literals in config/*.ts. Nested values, arrays, and environment-backed expressions remain read-only.
• SSL certificates are stored in ~/.stacks/ssl/, NOT in the project directory -- they persist across projects using the same domain
• Custom server configuration in server/ at the project root overrides the default server config via file copy (checked by useCustomOrDefaultServerConfig())
• The production server doubles as a queue worker when QUEUE_WORKER env var is set -- it imports the job by name from app/Jobs/ and exits after completion
• Docker build strips src/ directories, test files, sourcemaps, and node_modules from the image to minimize size
• The bun-plugin-stx serve plugin is resolved with a fallback: first tries normal import('bun-plugin-stx/serve'), then falls back to pantry/bun-plugin-stx/dist/serve.js
• buddy fresh is NOT the same as -- cleans AND reinstalls dependencies, while only removes artifacts
