Results for “typescript-eslint”

Sets up JavaScript/TypeScript projects with opinionated tooling and conventions including ESLint, TypeScript config, testing with Vitest, and monorepo setup.

ESLint configuration, custom rules, and plugin development.

Enforces ESLint v9 flat config rules across monorepos by scanning changed files via git diff, applying auto-fixable rules, and generating per-package lint reports with severity breakdowns.

Applies TypeScript/JavaScript rules for types, async behavior, APIs, tooling, tests, and architecture.

Creates custom ESLint rules using the ESLint RuleTester API and AST Explorer patterns, generating rule implementations with auto-fix suggestions based on estree node types and scope analysis.

TypeScript and JavaScript expert with deep knowledge of type-level programming, performance optimization, monorepo management, migration strategies, and modern tooling.

Master TypeScript's advanced type system including generics, conditional types, mapped types, template literals, and utility types for building type-safe applications. Use when implementing complex type logic, creating reusable type utilities, or ensuring compile-time type safety in TypeScript projects.

Bundle TypeScript libraries with tsup — zero-config, powered by esbuild. Use when someone asks to "bundle a TypeScript library", "build npm package", "tsup", "publish TypeScript to npm", "build ESM and CJS", "bundle with esbuild", or "library bundling with zero config". Covers ESM/CJS dual output, declaration files, tree-shaking, and npm publishing.

Runs ESLint to review code for style and correctness issues, with setup and documentation references.

Imported skill tsconfig from vercel

Applies Anthony Fu's opinionated tooling and conventions to JavaScript/TypeScript projects, covering code organization, TypeScript config, ESLint, testing, and pnpm monorepo setup.

Fixes all lint errors and formatting issues automatically

Escribe TypeScript estricto con tipos que ayudan: interfaces, genéricos, satisfies y uniones discriminadas, y resuelve errores de tipos.

Provides best practices for writing JavaScript/TypeScript tests using Jest, including test structure, mocking strategies, async testing, snapshot testing, and React component testing.

Create Zustand stores with TypeScript, subscribeWithSelector middleware, and proper state/action separation for React state management.

TypeScript Branded Types

Anthony Fu's opinionated tooling and conventions for JavaScript/TypeScript projects. Use when setting up new projects, configuring ESLint/Prettier alternatives, monorepos, library publishing, or when the user mentions Anthony Fu's preferences.

Use when tightening annotations in existing TypeScript, removing avoidable any or assertions, improving changed-file types, or reducing compiler errors without broad refactoring.

Use when configuring or maintaining a TypeScript repository, package manager, tsconfig files, linting, formatting, testing, builds, workspaces, CI, or publishing automation.

Provides domain-specific best practices for Node.js development with TypeScript, covering type stripping, async patterns, error handling, streams, modules, testing, performance, caching, logging, and more. Use when setting up Node.js projects with native TypeScript support, configuring type stripping (--experimental-strip-types), writing Node 22+ TypeScript without a build step, or when the user mentions 'native TypeScript in Node', 'strip types', 'Node 22 TypeScript', '.ts files without compilation', 'ts-node alternative', or needs guidance on error handling, graceful shutdown, flaky tests, profiling, or environment configuration in Node.js. Helps configure tsconfig.json for type stripping, set up package.json scripts, handle module resolution and import extensions, and apply robust patterns across the full Node.js stack.

Designs complex generic types, refactors `any` types to strict alternatives, creates type guards and utility types, and resolves TypeScript compiler errors.

XSLT injection testing: processor fingerprinting, XXE and document() SSRF, EXSLT write primitives, PHP/Java/.NET extension RCE surfaces. Use when user-controlled XSLT/stylesheet input or transform endpoints are in scope.

TypeScript Strict Mode

Provides domain-specific best practices for Node.js development with TypeScript, covering type stripping, async patterns, error handling, streams, modules, testing, performance, caching, logging, and more.
