Know what's in the toolbox

Frontend build tool and dev server

Serves source files as native ES modules during development, so the dev server starts almost instantly and hot module replacement stays fast as the project grows. Bundles for production.

AI coding agent

Anthropic's agentic coding tool. It reads your codebase, edits files, runs commands, and handles multi-step tasks from the terminal, IDE, desktop app, or browser.

AI coding agent

OpenAI's coding agent, available as an open-source CLI and as a cloud agent that works on tasks in parallel sandboxes.

API architectural style

Resources addressed by URLs and manipulated with standard HTTP methods and status codes. Simple, cacheable, and understood by every HTTP client.

API query language

Clients send a query describing exactly the fields they need and get back that shape in one request, from a single typed endpoint.

Container platform

Packages an app with its dependencies and configuration into a container image that runs the same on a laptop, CI, and production.

JavaScript package manager

A package manager that stores each package version once on disk and links it into projects, making installs fast and space-efficient. Its strict node_modules layout blocks imports of undeclared dependencies.

Monorepo build system

Runs tasks across a JavaScript monorepo in dependency order and caches the results by content hash, so unchanged packages are skipped locally and in CI. Remote caching shares results across machines.

Versioning and changelogs

Contributors add small changeset files describing what changed and how big the change is; Changesets turns them into version bumps and changelog entries across every package in a monorepo.

Electron packaging and updates

Packages an Electron app into installers for Windows, macOS, and Linux, handles code signing and macOS notarization, and pairs with electron-updater for auto-updates.
