SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It prevents inconsistent TypeScript project setups by enforcing a dependable baseline for compilation, linting, testing, and commit-time quality checks.

Core Features & Use Cases

  • Toolchain-aligned configuration: Provides a canonical tsconfig.json with strict typing defaults and a separate Jest test config.
  • ESLint flat config rules: Establishes deterministic linting (including JSDoc requirements and import ordering) that matches modern ESLint v9+ expectations.
  • Jest quality gate: Defines Jest configuration with coverage collection and strict global 100% thresholds suitable for spec-driven development.

Use case example: You are starting a new TypeScript repo or rescuing an existing one whose linting, type-checking, and test coverage are uneven; apply this standard to quickly converge on one consistent, reviewable configuration.

Quick Start

Ask an AI to “apply the typescript-code-standards standard to this repository by generating/adjusting tsconfig.json, eslint.config.mjs, jest.config.js, package.json scripts, and Husky + lint-staged pre-commit hooks, keeping the team/personal scope rules in mind.”

Frequently Asked Questions about typescript-code-standards

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I configure ESLint flat config with JSDoc and import-order rules in TypeScript?▼

To configure ESLint flat config with JSDoc and import-order rules, apply a canonical ESLint v9+ setup that establishes deterministic linting matching modern TypeScript expectations. This standardizes linting behavior across new and existing TypeScript projects.

Why does my TypeScript project need Husky and lint-staged pre-commit hooks?▼

TypeScript projects need Husky and lint-staged pre-commit hooks to enforce commit-time quality checks. This prevents inconsistent code by running automated linting and formatting gates before changes are committed to the repository.

Can I enforce strict 100% Jest coverage thresholds in a TypeScript project?▼

You can enforce strict 100% Jest coverage thresholds by applying a canonical Jest configuration with coverage collection. This establishes a quality gate suitable for spec-driven TypeScript development.

What's the best way to standardize tsconfig.json strict typing defaults for a new TypeScript repo?▼

The best way to standardize tsconfig.json strict typing defaults is to apply a canonical compiler configuration. This enforces a dependable baseline for compilation and separates Jest test configuration.

Does this TypeScript toolchain configuration require adjusting existing npm scripts?▼

Yes, applying this TypeScript toolchain standard involves aligning npm scripts and quality gates. This ensures compilation, linting, testing, and pre-commit tooling integrate properly into your existing workflow.

When do I need to standardize TypeScript project tooling configuration?▼

You need to standardize TypeScript project tooling configuration when starting a new repo or rescuing an existing one with uneven linting, type-checking, and test coverage, ensuring one consistent, reviewable setup.
