TSBB is a zero-config CLI that helps you develop, test, and publish modern TypeScript project.

import { transformFile, loadPartialConfig } from '@babel/core';
export function transform(fileName, ops = {}) {
    const babelOptions = loadPartialConfig({ ...ops, cwd: process.cwd() });
    return new Promise((resolve, reject) => {
        transformFile(fileName, { ...babelOptions?.options, babelrc: true }, (err, result) => {
            if (err) {
                return reject(err);
            }
            resolve(result);
        });
    });
}
