@tsconfig/node16

@tsconfig/node16 provides a TypeScript configuration base specifically optimized for Node.js 16 runtime environments. It establishes optimal compiler settings including ES2021 target support, Node.js 16 module resolution, strict type checking, and performance optimizations for Node.js 16 applications.

Package Information

• Package Name: @tsconfig/node16
• Package Type: npm
• Language: JSON (TypeScript configuration)
• Installation: npm install --save-dev @tsconfig/node16

Core Usage

Add to your tsconfig.json:

{
  "extends": "@tsconfig/node16/tsconfig.json"
}

Alternative installation methods:

# npm
npm install --save-dev @tsconfig/node16

# yarn
yarn add --dev @tsconfig/node16

Basic Usage

Create or update your tsconfig.json file to extend the Node.js 16 configuration:

{
  "extends": "@tsconfig/node16/tsconfig.json",
  "compilerOptions": {
    // Your additional options can override or extend the base
    "outDir": "./dist",
    "rootDir": "./src"
  },
  "include": ["src/**/*"],
  "exclude": ["node_modules", "dist"]
}

Architecture

The configuration is structured as a single JSON file that provides:

• Base Configuration: Core TypeScript compiler options optimized for Node.js 16
• Module System: Node.js 16 module resolution with ES module interoperability
• Type Safety: Strict type checking enabled by default
• Performance: Library checking optimization for faster builds
• Standards Compliance: ES2021 target for modern JavaScript features

Capabilities

TypeScript Configuration

Provides the complete TypeScript configuration optimized for Node.js 16 environments.

{
  "$schema": "https://json.schemastore.org/tsconfig",
  "display": "Node 16",
  "_version": "16.1.0",
  "compilerOptions": {
    "lib": ["es2021"],
    "module": "node16",
    "target": "es2021",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "moduleResolution": "node16"
  }
}

Configuration Properties

Schema and Metadata

{
  "$schema": "https://json.schemastore.org/tsconfig",
  "display": "Node 16",
  "_version": "16.1.0"
}

• $schema: Provides JSON schema validation and IDE support
• display: Human-readable name for the configuration
• _version: Version of this specific configuration base

Compiler Options

{
  "compilerOptions": {
    "lib": ["es2021"],
    "module": "node16", 
    "target": "es2021",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "moduleResolution": "node16"
  }
}

Core Settings:

• lib: ["es2021"] - Includes ES2021 standard library definitions
• module: "node16" - Uses Node.js 16 specific module system
• target: "es2021" - Compiles to ES2021 JavaScript features
• moduleResolution: "node16" - Uses Node.js 16 module resolution algorithm

Type Safety:

• strict: true - Enables all strict type checking options
• esModuleInterop: true - Enables importing CommonJS modules as ES modules

Performance:

• skipLibCheck: true - Skips type checking of library files for faster builds

Extension Usage

The configuration is designed to be extended in your project's tsconfig.json:

{
  "extends": "@tsconfig/node16/tsconfig.json"
}

You can combine with additional configurations using TypeScript 5.0+ multiple extends:

{
  "extends": [
    "@tsconfig/node16/tsconfig.json", 
    "@tsconfig/strictest/tsconfig.json"
  ]
}
