A shareable TypeScript configuration with strict type checking and modern compiler options.

• ✅ Strict type checking configuration
• 🔒 All strict mode options enabled
• 🚀 Latest ESNext target and module system
• 📦 Node.js nodenext module resolution support
• 🏗️ Monorepo-specific configuration included
• 🔄 ESM interoperability out of the box

npm install --save-dev @camaro/tsconfig

Or using other package managers:

# pnpm
pnpm add -D @camaro/tsconfig

# yarn
yarn add -D @camaro/tsconfig

Create a tsconfig.json file in your project root and extend the base configuration:

{
  "extends": "@camaro/tsconfig/base.json",
  "compilerOptions": {
    "outDir": "./dist"
  },
  "include": ["src"]
}

If you're using a monorepo (such as pnpm workspaces, yarn workspaces, or lerna), use the dedicated monorepo configuration:

{
  "extends": "@camaro/tsconfig/monorepo.json",
  "compilerOptions": {
    "outDir": "./dist"
  },
  "include": ["src"]
}

The base configuration includes the following strict compiler options:

• strict: true - Enable all strict type checking options
• noImplicitReturns: true - Ensure all code paths in functions return a value
• noFallthroughCasesInSwitch: true - Prevent fallthrough errors in switch statements
• noUnusedLocals: true - Report unused local variables
• noUnusedParameters: true - Report unused parameters
• noUncheckedIndexedAccess: true - Add undefined checks for index access
• noImplicitOverride: true - Ensure overriding members use the override modifier
• allowUnreachableCode: false - Disallow unreachable code
• allowUnusedLabels: false - Disallow unused labels

• module: "nodenext" - Use Node.js ESM and CommonJS support
• moduleResolution: "nodenext" - Node.js module resolution strategy

• inlineSourceMap: true - Generate inline source maps

• esModuleInterop: true - Enable ES module interoperability
• forceConsistentCasingInFileNames: true - Enforce consistent file name casing

• target: "ESNext" - Compile to the latest ECMAScript standard
• lib: ["ESNext"] - Use the latest standard library type definitions

• skipLibCheck: true - Skip type checking of declaration files for better performance

Extends base.json with additional options:

• composite: true - Enable project references and incremental compilation, suitable for monorepo scenarios

1. Strictness: Enables all TypeScript strict checking options to catch potential issues during development
2. Modern: Uses ESNext target to support the latest JavaScript features
3. Node.js Friendly: Uses nodenext module system for perfect Node.js ESM support
4. Optimized Developer Experience: Configured with reasonable error detection and code hints
5. Monorepo Support: Provides dedicated monorepo configuration with project reference support
