create-redux-module/examples/counter/config/jest/fileTransform.js

Helper to create redux namespaced action creators & reducers with minimal boilerplate. Easily use promise based services (API calls, for example) from the actions.

const path = require('path');

// This is a custom Jest transformer turning file imports into filenames.

module.exports = {
  process(src, filename) {
    return 'module.exports = ' + JSON.stringify(path.basename(filename)) + ';';
  },
};
