Create production-ready tsconfig.json files in seconds. Get TypeScript configurations optimized for React, Next.js, Node.js, or NPM libraries—with the exact compiler options you need.

What is tsconfig.json?

tsconfig.json is the configuration file that tells the TypeScript compiler how to process your code. It defines compiler options like target JavaScript version, module system, type checking strictness, and output settings. Every TypeScript project needs a tsconfig.json at its root.

Common Use Cases

Starting New Projects

Generate a properly configured tsconfig.json for React, Next.js, Vue, or Node.js projects in seconds.

Learning TypeScript

Study real-world configurations to understand compiler options, strictness levels, and module resolution.

Publishing NPM Packages

Create tsconfig.json optimized for library publishing with declarations, source maps, and proper exports.

Migrating to TypeScript

Start with relaxed settings (allowJs, strict: false) and gradually increase strictness as you convert.

Frequently Asked Questions

What is tsconfig.json?

tsconfig.json is the configuration file for TypeScript projects. It specifies the root files and compiler options required to compile a TypeScript project, including target JavaScript version, module system, strictness settings, and output configuration.

How do I create a tsconfig.json file?

You can create tsconfig.json by running "tsc --init" in your project directory, which generates a file with default options. Alternatively, use our generator to create a customized tsconfig.json with templates for React, Next.js, Node.js, or other frameworks.

What does "strict: true" enable in tsconfig?

"strict: true" enables all strict type-checking options: strictNullChecks, strictFunctionTypes, strictBindCallApply, strictPropertyInitialization, noImplicitAny, noImplicitThis, useUnknownInCatchVariables, and alwaysStrict. It's recommended for catching more errors at compile time.

What is the difference between module and moduleResolution?

"module" specifies the module code generation (CommonJS, ESNext, etc.) while "moduleResolution" determines how TypeScript finds modules when you import them. Modern projects typically use "ESNext" or "NodeNext" for module and "bundler" or "NodeNext" for moduleResolution.

Should I use "noEmit: true" in my tsconfig?

Use "noEmit: true" when a bundler like Vite, Webpack, or esbuild handles compilation. TypeScript then only performs type checking. For Node.js projects where you want TypeScript to compile your code, keep noEmit false.

How do I set up path aliases like @/* in TypeScript?

Set "baseUrl" to "." and add "paths" with your alias pattern: {"@/*": ["./src/*"]}. This lets you import with @/components instead of relative paths. Note: bundlers like Vite also need matching alias configuration.
