State-of-the-art JavaScript and TypeScript engineering (2026) for both writing and auditing code. Covers strict TypeScript configuration and type design, language idioms and pitfalls, async patterns, Node.js backends, JS/TS-specific security (XSS, prototype pollution, supply chain, injection), frontend/React and Node performance, and testing/tooling. Use whenever building, reviewing, refactoring, or security-auditing code involving JavaScript, TypeScript, Node, npm, React, frontend code…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# SOTA JavaScript / TypeScript Engineering

## Purpose

This skill encodes 2026 state-of-the-art for JS/TS so generated code is strict, secure, and fast by default — and so audits of existing code find the bug classes that actually bite: untyped boundaries, floating promises, XSS sinks, prototype pollution, supply-chain gaps, event-loop blocking, and leak-prone listeners. It has two operating modes; pick one explicitly at the start of a task.

Baseline assumptions (mid-2026): TypeScript ≥5.9 strict (6.0 = last JS-based compiler; 7.0 Go-native since July 2026, shipped as the regular `typescript` package **with no compiler API** — typescript-eslint, including the non-negotiable `no-floating-promises`, and Volar-based frameworks (Vue/Angular/Astro/Svelte) still need the 6.0 API, so install `typescript` as `npm:@typescript/typescript6` beside 7.0 until they support 7: [rules/01](rules/01-typescript-config-and-types.md)), ESM-first, Node LTS ≥22 (run the line marked Active LTS at github.com/nodejs/Release; 26 is scheduled for LTS on 2026-10-28 and ships Temporal by default), ES2024+ available, React 19.2-era with Server Components and React Compiler (stable since 1.0) where relevant…

How to install

The exact contents, by fingerprint
mdr add martinholovsky/sota-skills/sota-javascript-typescript@sha256:4720806cb577ec82

The line at the top of this page pins the label git:20261026.808c340, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
