@deb0shic/tsconfig

Shared TypeScript compiler configurations. Five presets, all extending base.json:

Preset	Extends	For
base.json	—	Strict defaults for any project. Not usable directly — it does not set target / module.
node.json	base	Node 20+, ESM, node_modules resolution.
library.json	base	Publishable library. Emits declarations + declaration maps + source maps.
next.json	base	Next.js 14/15 App Router; JSX preserve, path aliases, noEmit.
strict-plus.json	base	Every extra safety flag TypeScript ships. Slower to build; catches more.

Install

pnpm add -D @deb0shic/tsconfig

Use

Point your tsconfig.json at the preset that fits:

{
  "extends": "@deb0shic/tsconfig/next.json",
  "include": ["**/*.ts", "**/*.tsx", ".next/types/**/*.ts"]
}

Or extend more than one — later entries win:

{
  "extends": ["@deb0shic/tsconfig/library.json", "@deb0shic/tsconfig/strict-plus.json"]
}

What the presets set

base.json — strict: true, noUncheckedIndexedAccess, noImplicitOverride, exactOptionalPropertyTypes, verbatimModuleSyntax, skipLibCheck. Nothing about output; those go in the concrete presets.

node.json — target: ES2022, module: NodeNext, moduleResolution: NodeNext, types: ["node"]. ESM-first.

library.json — declaration, declarationMap, sourceMap, emitDeclarationOnly off, stripInternal. Also composite for project references.

next.json — jsx: preserve, module: esnext, moduleResolution: bundler, noEmit, path alias "@/*": ["./*"], plus the standard set for Next's plugin.

strict-plus.json — noUnusedLocals, noUnusedParameters, noFallthroughCasesInSwitch, noImplicitReturns, useUnknownInCatchVariables. Turns compile time up; catches more real bugs.
