When upgrading to Jest 27 and using this transform, this is the output:

Jest: a transform must export something

I’m guessing it’s just something tiny about how Jest transform now expects things, like in this breaking change:

[jest-transform] [BREAKING] Do not export ScriptTransformer class, instead export the async function createScriptTransformer (#11163) (source)

Hi @cwmoo740,

We are using your transformer within our React native application, right now we are adding support for react native web, thus we are using CRA and they are forcing us to switch from:
import Logo from './logo.svg'; -> import {ReactComponent as Logo} from './logo.svg';
I have also mentioned these changes in this issue

What we need to do is change process.js module.exports to support both exports, default and named:
module.exports = { default: ${name}, ReactComponent: ${name} };

I believe this would not be a breaking change, It would be super cool if I could provide a pull request or if you could implement it.

Here is a quick fix for postinstall npm/yarn script:

"postinstall": "sed -e \"s|module.exports = \\${name};|module.exports = {default: \\${name}, ReactComponent: \\${name}};|g\" -i.bak ./node_modules/jest-svg-transformer/lib/process.js",

Hi! Would you be willing to add the source code of your NPM module to this repo?
