import fs from 'node:fs/promises';

export default async function writePrettyFile(filePath, content) {
    await fs.mkdir(path.dirname(filePath), { recursive: true });
    const options = await prettier.resolveConfig(filePath);
    const defaultPrettierOptions = {
        // Let prettier automatically infer parser from the file path
        filepath: filePath,
    };
    const formatted = await prettier.format(typeof content === 'object' ? JSON.stringify(content) : content, options
        ? { ...defaultPrettierOptions, ...options }
        : defaultPrettierOptions);
    await fs.writeFile(filePath, formatted);
