@fusioncharts/fusiontime/jest.config.js

FusionCharts JavaScript time-series charting framework

// Package-scoped Jest config for fc-timeseries:
// - Uses jsdom because the code under test may touch browser globals.
// - Applies babel-jest so ESM in our sources is transpiled.
// - Allows transpiling ramda/es and maps it to the CJS build to avoid resolver issues.
module.exports = {
  testEnvironment: 'jsdom', // provide window/document for code paths that rely on the DOM
  transform: {
    '^.+\\.(js|mjs)$': ['babel-jest', { presets: ['@babel/preset-env'] }] // transpile ES modules
  },
  transformIgnorePatterns: ['node_modules/(?!ramda/es)'], // ensure ramda/es is also passed through Babel
  moduleNameMapper: {
    '^ramda/es/(.*)$': 'ramda/src/$1', // point ramda/es imports to the CJS sources
    '^ramda/es$': 'ramda/src'
  }
};
