ESM-compatible exports - #162
Merged

Conversation
Node.js handles ESM-CJS interoperability by using its [cjs-module-lexer](https://github.com/nodejs/cjs-module-lexer) to parse CJS files and turn their exports into named exports. cjs-module-lexer is deliberately limited in its capabilities. Switching export styles makes jsonfile's exports recognizable by cjs-module-lexer so that ESM code such aborts ``` import { readFileSync } from 'jsonfile' ``` can work as expected, without having to change jsonfile itself to ESM. Fixes #153

To demonstrate / test this locally, create a file, import { readFileSync } from './index.js';
console.log(readFileSync('./package.json'));Then run it with and without this change. |

Thanks @joshkel! Will try to release sometime next week (I don't like releasing popular libraries on weekends). |
