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.

There is a great introductory blog post here.

Install

npm install

Running codemods

In this directory, you can try out the codemod with this command:

npm run transform -- -d -p -t replace-console-with-log.js test.js
# if you want to transform code in the api folder:
npm run transform -- -d -p -t 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. Just remove those options to actually perform the transformation.

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 ../../api-js/src/__tests__/*.
