Codemods

This directory contains scripts for making code changes that are wide-ranging, complex or both. Codemods are done with Facebook's jscodeshift tool which parses JavaScript into an Abstract Syntax Tree allowing edits on language elements rather than just strings/characters of text.

Install

Jscodeshift is installed globally with the following command

npm install -g jscodeshift

Running the codemod

From the project root, you can try out the codemod with this command:

jscodeshift -d -p -t scripts/codemods/remove-dotenv-from-tests.js api-js/src/__tests__/*

This command won't make any actual edits (-d aka dry run) and will just print (-p) the changes it would have made.

The description of how to do the transformation is contained in ./transform.js or whatever file the -t flag points to. That transform will be applied to the files found with the file glob src/__tests__/*.
