build Overview of the continuous build system: an always-active project server that handles installation, compilation, migration, and testing on every change.
browser Tools for previewing your app: live browser reloads, device previews, screenshots, and Chrome automation via the DevTools Protocol.
packages Managing dependencies: seamless installation, local package watching, and integrating package updates directly into your workflow.
typescript Integrated TypeScript support: built-in compiler checks for TypeScript, HTML, and configuration files.
html Reactive and dynamic HTML: write standard HTML that is server-rendered and instantly updated in the browser.
assets Asset management: automatic content hashing at build time, importing assets as values, or serving them dynamically via routes.
rpc Simplified server-client communication: call server functions directly from the browser, with type safety ensured at build time.
router Routing essentials: define routes, handlers, and manage request/response flows efficiently.
session User sessions: secure cookie-based sessions, authentication, and reactive session state management.
database Integrated PostgreSQL: inline, parameterized SQL at build time with support for nested transactions.
migrations Database migrations: edit SQL files and apply changes automatically—no separate migration step needed, with instant replays on edits.
livetable Real-time data sync: keep rows updated live in all connected browsers with optimistic UI updates.
channel Realtime communication: server-to-browser message channels for building interactive, live features.

email Integrated emailing: send emails directly from your application.
payments Easy Stripe integration: inline product/pricing, built-in test mode, and automatic webhook setup for seamless payments.
