Do not assume transform files are .js

[eventualbuddha]

This makes it possible to write codemods with TypeScript using a .ts extension with ts-jest.

@eventualbuddha How are you getting this to work when running the actual codemod? I've been working on a project and saw this, so converted my index.js to index.ts and can get it running tests and passing fine, but when I try to actually run the codemod, I get an error

ERROR Transform file ***/decorate-service/index.js does not exist

Wondering if I'm invoking the project incorrectly?

@mfeckie - Did you setup ts-jest also?

[mfeckie]

@rwjblue Yep, ts-jest works happily.

In the end I just converted the file back to .js because I was more interested in getting the project working.

I was assuming that it should just work ™️ after reading https://github.com/facebook/jscodeshift/releases/tag/v0.6.0

and https://github.com/facebook/jscodeshift#transform-module

Wondering if there's something I'm missing.

@mfeckie Here's a branch of one of the Ember codemods showing it working with TypeScript:

ember-codemods/ember-sinon-sandbox-codemod@master...eventualbuddha:typescript

[mfeckie]

Yeah, so I had similar config and everything works fine in testing but when I come to run the actual code, I get ERROR Transform file .../index.js does not exist
