runtime:db

The runtime:db API is a portable connection surface with an explicit driver. Read the part you need:

Connections and pooling — imports, connect(), connection options, and cancellation.
Queries, rows, and errors — SQL templates, execution, subscriptions, transactions, rows, and error codes.
Database drivers — the driver contract and value mapping.

For implementation guidance, see Writing a database driver or an ORM.

ES-Runtime — a secure, standards-based server runtime

ES-Runtime (esrun) is a V8-based, standards-first JavaScript runtime: it runs ES modules against the WinterTC Web-platform APIs — fetch, URL, streams, WebCrypto, encoding, timers, events — with notably fast startup and a low memory footprint. Host features (filesystem, network, HTTP server, processes) are exposed as asynchronous runtime: modules. It is ESM-only and built on Rust; no CommonJS and no Node.js compatibility layer.

Documentation

Overview — what ES-Runtime is, its design, and how the pieces fit together.
Installation — install the esrun CLI and run a first module.
Module system — ESM-only loading and the runtime: built-in module scheme.
Global objects — the Web-standard globals available, and what is intentionally absent.
🔒 Security — vulnerability reporting, hardening, and capability-based I/O.
Scope & non-goals — a runtime, not a toolchain; no Node.js compatibility.

Development

Development with esdev — scaffold, build, watch, test, debug, and ship projects.
Starting a project — create a working project from a template.
The dev loop — rebuild, restart, and update a running page.

API reference

API overview — the runtime: standard modules and the CLI.
esrun CLI — running a module, -e snippets, --timeout, esrun types, esrun upgrade.
runtime:process — env, args, cwd(), platform, arch, exit().
runtime:path — platform-aware path utilities and file: URL interop.
runtime:fs — Blob-based async file I/O, jailed to a root. Gated on FileRead/FileWrite.
runtime:net — TCP sockets (WinterTC Sockets API). Gated on Net/NetListen.
runtime:http — an HTTP/1.1 + HTTP/2 server, serve((request) => response). Gated on NetListen.
