@vitus-labs/tools-typescript

Shared TypeScript configuration presets.

Installation

bun add -d @vitus-labs/tools-typescript

Peer dependency: typescript 6.x or 7.x

Presets

The presets deliberately do not set include / exclude. TypeScript resolves those paths relative to the config file that declares them, so a preset's include would point inside node_modules. Always set them in your own tsconfig.json, e.g. "include": ["src"] and "exclude": ["node_modules", "lib"] (for Next.js: "include": ["next-env.d.ts", "**/*.ts", "**/*.tsx"]).

lib — for libraries

Strict TypeScript config targeting ES2024 with bundler module resolution.

{
  "extends": "@vitus-labs/tools-typescript/lib",
  "include": ["src"]
}

Key settings:

• target: ES2024, module: Preserve, moduleResolution: Bundler
• strict: true, noUncheckedIndexedAccess: true
• jsx: react-jsx
• declaration: true, declarationMap: true, sourceMap: true
• verbatimModuleSyntax: true
• types: ["node"] — override with "types": [] (or your own list) for browser-only libraries without @types/node

node — for Node.js packages

{
  "extends": "@vitus-labs/tools-typescript/node",
  "include": ["src"]
}

Key settings: module/moduleResolution: NodeNext, rewriteRelativeImportExtensions: true, types: ["node"], strict: true.

nextjs — for Next.js applications

{
  "extends": "@vitus-labs/tools-typescript/nextjs",
  "include": ["next-env.d.ts", "**/*.ts", "**/*.tsx"],
  "exclude": ["node_modules"]
}

Key settings:

• target: ES2024, module: ESNext, moduleResolution: Bundler
• strict: true, noUncheckedIndexedAccess: true
• jsx: preserve (Next.js handles the JSX transform)
• incremental: true
