⚠️ BREAKING CHANGES (if using lint rules)

• Transition from deprecated @babel/plugin-syntax-import-assertions to the new @babel/plugin-syntax-import-attributes and enable option deprecatedAssertSyntax for backward compatibility with import assertions. Since this is a peer dependency, consumers must switch plugins to match.

• Update README with instructions on how to consume Babel, ESLint, JavaScript, rollup.js, and TypeScript configurations.

• Publish new export utils and utility function ifEmpty().

  • Adjust rule import/no-unused-modules for Jest mocks to (a) no longer report unreferenced exports and (b) report missing exports.
  • Relax rule max-statements-per-line with an increased maximum of two across the board. Previously, the maximum was two for Jest mocks and tests, and one for everything else.
  • Exempt JSX files from rule multiline-ternary as it clashes with react/jsx-indent, which in turn clashes with indent.
  • Turn off rule react/jsx-props-no-spreading for TypeScript files, where prop spreading is safe.
• Implement new lint rules:
  • @typescript-eslint/consistent-type-exports
  • @typescript-eslint/consistent-type-imports
