repoify-js/commands/pull.js

Repoify is a custom-built Version Control System (VCS) created as a fun learning project to explore core concepts of version control, file management, and cloud storage integration using modern technologies.

import { filePath, fsAsync } from "../utils/fileUtils.js";
import { s3, S3_BUCKET } from "../config/aws.js";

const pullRepo = async () => {

      .listObjectsV2({
        Bucket: S3_BUCKET,
        Prefix: "commits/",
      })
      .promise();

    const objects = data.Contents;

    for (const object of objects) {
      const key = object.Key;
      const commitDir = filePath.join(
        commitsPath,
        filePath.dirname(key).split("/").pop()
