Welcome to Deno

# Deno > Deno is a secure JavaScript/TypeScript runtime built on V8 and Rust, > distributed as a single binary. TypeScript, formatting, linting, testing, and > a standard library work with zero configuration. Programs are sandboxed by > default; capabilities (network, filesystem, etc.) are granted explicitly via > --allow-* flags. Deno natively supports npm packages and Node.js built-in > modules. - [llms-full-guide.txt](https://docs.deno.com/llms-full-guide.txt): Complete agent-oriented guide with CLI reference, code examples, and usage patterns (publish alongside this file) - [llms-summary.txt](https://docs.deno.com/llms-summary.txt): Compact index of all documentation sections - [llms-full.txt](https://docs.deno.com/llms-full.txt): Full documentation content dump (large) ## Runtime - [Getting Started](https://docs.deno.com/runtime/getting_started/first_project): Scaffold a project, run code, and execute tests - [CLI Reference](https://docs.deno.com/runtime/reference/cli/): All deno subcommands and flags (run, test, fmt, lint, task, compile, install) - [Configuration (deno.json)](https://docs.deno.com/runtime/fundamentals/configuration): Project config, tasks, import maps, TypeScript settings - [Modules and Imports](https://docs.deno.com/runtime/fundamentals/modules): jsr:, npm:, and node: specifiers; import maps; dependency management - [Security and Permissions](https://docs.deno.com/runtime/fundamentals/security): Sandbox model and --allow-* permission flags - [Node.js Compatibility](https://docs.deno.com/runtime/fundamentals/node): Running Node projects, npm packages, and node: built-ins in Deno - [Testing](https://docs.deno.com/runtime/fundamentals/testing): Built-in test runner, assertions, mocking, coverage - [TypeScript Support](https://docs.deno.com/runtime/fundamentals/typescript): TypeScript configuration and type checking - [HTTP Server](https://docs.deno.com/runtime/fundamentals/http_server): Deno.serve API, request handling, WebSockets - [Standar
