@significa/tsconfig

Significa's shared TypeScript configurations. Four variants, all strict, all noEmit (Biome handles syntax; tsc handles type-checking only).

Install

pnpm add -D -E @significa/tsconfig typescript

Variants

base — neutral foundation

Strict mode, target: ES2023, module: preserve, noEmit, verbatimModuleSyntax, erasableSyntaxOnly. No DOM lib, no JSX, no allowImportingTsExtensions. Pick this only if your code is truly runtime-agnostic (rare). Most projects extend react, astro, or node directly.

{
  "extends": "@significa/tsconfig/base",
  "include": ["src"]
}

react — TanStack Start, Vite React

Extends base. Adds DOM lib, jsx: react-jsx, allowImportingTsExtensions.

{
  "extends": "@significa/tsconfig/react",
  "include": ["src", "vite.config.ts"]
}

astro — Astro projects

Extends base. Adds DOM lib, jsx: preserve, allowImportingTsExtensions. Pre-includes ${configDir}/.astro/types.d.ts and ${configDir}/**/*, excludes dist.

{
  "extends": "@significa/tsconfig/astro",
  "compilerOptions": {
    "paths": { "@/*": ["./src/*"] }
  }
}

node — Drizzle scripts, CLIs, tsx-run code, API-only services

Extends base. Swaps to module: NodeNext + moduleResolution: NodeNext, adds types: ["node"]. No DOM lib (the base default is fine for Node).

{
  "extends": "@significa/tsconfig/node",
  "include": ["src", "scripts"]
}
