bunjs

Bun and TypeScript toolkit. A /bunjs:bun index routes any task to the right one of eight task-shaped skills — setup, HTTP, errors, testing, security, production, performance, TUI — each shipping copyable code verified against Bun. Only Bun is tested.

Install

claudeup

Find bunjs on the Plugins tab and turn it on. claudeup registers the magus marketplace if you do not have it, and installs what the plugin needs to actually run — binaries, MCP servers, CLI tools.

For a team, press s to save your plugins as a profile and commit it. Everyone else runs claudeup install — see Teams and profiles.

Prefer to do it by hand? Installing Magus has the manual path.

How to run these: Bun and TypeScript tasks — what to type, what it asks you, and which options change the outcome.

Commands

Command	What it does
/bunjs:bun	Route a Bun/TypeScript task to the right bunjs skills. Loads the index, reads only what the task needs, then does the work.
/bunjs:errors	Add or review error handling and resilience in a Bun/TypeScript service. Loads the errors skill, then works the task through its workflow.
/bunjs:http-service	Build, review or debug a Bun HTTP service. Loads the http-service skill, then works the task through its workflow.
/bunjs:performance	Diagnose or fix Bun/TypeScript performance. Loads the performance skill, then works the task through its workflow.
/bunjs:production	Prepare a Bun service for production. Loads the production skill, then works the task through its workflow.
/bunjs:project-setup	Start or restructure a Bun/TypeScript project. Loads the project-setup skill, then works the task through its workflow.
/bunjs:security	Harden or security-review a Bun/TypeScript service. Loads the security skill, then works the task through its workflow.
/bunjs:testing	Write, fix or review Bun tests. Loads the testing skill, then works the task through its workflow.
/bunjs:tui	Build, review or debug an OpenTUI terminal UI. Loads the tui skill, then works the task through its workflow.

Why a skill lands in one row or another

	Skill	What it covers
●	bunjs:bun	Router for the eight Bun/TypeScript skills — setup, HTTP, errors, testing, security, production, performance, TUI. Says which to read for a task, without loading them. Any Bun or TS work.
○	bunjs:errors — 4 more docs	Error handling and resilience for Bun/TypeScript — operational vs programmer errors, AppError hierarchy, centralized handler, boundary validation, timeout/retry/circuit breaker.
○	bunjs:http-service	Build or review a Bun HTTP service — Bun.serve declarative routes, middleware composition, request context, status/ETag/streaming helpers, graceful lifecycle.
○	bunjs:performance	Diagnose and fix Bun/TypeScript performance — event-loop blocking, measured native fast paths, benchmarking that does not lie, streaming, caching, workers, memory.
○	bunjs:production	Ship a Bun service — graceful shutdown ordering, structured logging, liveness vs readiness, multi-stage Docker, signals and PID 1, frozen lockfiles, CI.
○	bunjs:project-setup	Start or restructure a Bun/TypeScript project — folder structure by business component, strict tsconfig, typed env config, workspaces and catalogs, bunfig, linting.
○	bunjs:security	Harden or review a Bun/TypeScript service — secrets, password and token handling, SQL injection, authn/authz, rate limiting, CORS and security headers, dependency audit.
○	bunjs:testing — 4 more docs	Write and fix Bun tests — bun:test surface, component tests over HTTP, doubles, coverage gating, flake control. Ships a tested harness, fake upstream and builders.
○	bunjs:tui — 30 more docs	Build, review, or debug OpenTUI terminal UIs — React JSX or core constructs, Yoga flexbox, gradient meters, colour screenshots. Any Bun/TypeScript TUI. Only Bun is tested;
