Usage

Async

// directory can be an absolute or relative path
// If it's a relative path, it is relative to the current working directory (process.cwd())
const directory = 'src';
findBabelConfig(directory).then(({ file, config }) => {
    if (file) {
        // file is the file in which the config is found
        console.log(file);
        // config is a JS plain object with the babel config
        console.log(config);
    }
});

Sync

// directory can be an absolute or relative path
// If it's a relative path, it is relative to the current working directory (process.cwd())
const directory = 'src';
const { file, config } = findBabelConfig.sync(directory);
// if c === null, the config wasn't found
if (file) {
    // file is the file in which the config is found
    console.log(file);
    // config is a JS plain object with the babel config
    console.log(config);
}
