ts-enhance

Alpha version of a package rename. Not stable. Do not use!

Improves a project's TypeScript code by creating and improving types. 💗

Usage

ts-enhance is a CLI tool that iteratively improves TypeScript types in existing code. It can:

• Add type annotations to fix noImplicitAny and noImplicitThis type errors
• Annotate missing nulls and undefineds to fix strictNullChecks type errors
• Remove unnecessary annotations for types that can be inferred
• Remove unnecessary constituents and members of union types and object types

⚡ To start, the ts-enhance command will launch an interactive guide to setting up a configuration file. ⚡

npx ts-enhance

👋 Welcome to ts-enhance! 👋
This will create a new ts-enhance.json for you.
...

After, use ts-enhance --config ts-enhance.json to convert your files with the same settings.
