TSConfig Generator

What is TSConfig Generator?

TSConfig Generator creates TypeScript tsconfig.json configuration files with sensible defaults for different project types — React, Node.js, library, monorepo, and Deno. It covers all compiler options organized by category including strict type checking, module resolution, emit behavior, path mapping, and project references. The tool explains each option's effect with code examples showing how the setting changes compilation behavior, and warns about common incompatible option combinations.

TypeScript developers starting new projects, tech leads standardizing compiler configurations, and library authors configuring build output settings. The tool runs entirely in your browser — your data never leaves your device.

How to Use TSConfig Generator

1. Select your project type preset — React, Node.js, library, monorepo, or custom
2. Customize compiler options grouped by category — strictness, modules, emit, paths
3. Review warnings about incompatible or conflicting option combinations
4. Download the generated tsconfig.json or copy the configuration

Common Use Cases

• Setting up TypeScript for a new React project with JSX and module resolution configured correctly
• Configuring a Node.js backend project with ES Modules and proper path resolution
• Creating a library tsconfig with declaration file generation and source maps
• Setting up project references for TypeScript monorepo workspace builds

Pro Tips

• Enable all strict mode options (strict: true) for new projects — retrofitting strictness onto a large codebase is painful; strict: true enables strictNullChecks, noImplicitAny, strictFunctionTypes, and 7 other checks that catch real bugs
• Use moduleResolution: 'bundler' for projects using webpack, Vite, or esbuild — it matches how bundlers actually resolve modules, supporting package.json exports and imports fields that the older 'node' resolution mode does not handle
• Path aliases in tsconfig (paths) only affect type checking, not runtime resolution — you also need to configure your bundler (webpack alias, Vite resolve.alias) or use tsconfig-paths for Node.js runtime; without both, imports compile but fail at runtime
