Fix for breaking change in Jest V28.

[farwinit]

Jest V28 has a breaking change, requiring the process function to return an object, rather than a string. This pull request fixes that, however it will probably break for earlier Jest versions. I had a look at the Jest docs, but couldn't spot any way to see which Jest version is running.

Hello there, can we merge this branch and create a new release on npm? 😄

Big thanks for the fix

Running into this issue as well after upgrading to Jest 28. @half-halt please release a new version with this change.

In the meantime, you can write a tranformer wrapper like...

// in <rootDir>/jestSvgTransformerWrapper.js
const svgJest = require('svg-jest');

module.exports = {
  process(...args) {
    return {
      code: svgJest.process(...args)
    };
  }
};

then in your jest.config, define the transformer like...

 '\\.svg$': '<rootDir>/jestSvgTransformWrapper.js',

Just mentioning I did

yarn add -D svg-jest@farwinit/svg-jest#support_jest_v28
