TypeScript all the way 🚀

Strongly typed code and code completion with @types/jscodeshift

Installation

npm i

or

yarn

Run codemod

npx jscodeshift -t ./examples/simple-rename.ts --extensions=ts --parser=ts './**/*.ts' --print --dry

Omit --dry to write the transformed source back to disk.

Test

Debug

Use the pre-configured VSCode launcher to run tests and debug your transformer.

Behind the scenes

Use @babel/parser in https://astexplorer.net when working with the jscodeshift's default parser (default: babel).
