Add MERN Stack With Next JS Project to GitHub

Organize Your Project Structure

In your project directory, ensure you have two main folders: frontend for the Next.js application and backend for the Node.js/Express server.

Push Your Project to GitHub

Initialize a Git repository in your project folder, commit your code, and push it to a GitHub repository: git init git add . git commit -m "Initial commit for MERN stack app" git remote add origin <your-github-repo-url> git push -u origin main

To upload your project from a local machine (macOS) to GitHub, follow these steps:

Initialize a Git Repository

Navigate to your project directory in the terminal. Open a terminal window and use cd to navigate to your project folder: cd /path/to/your/project If the project folder is not yet a Git repository, initialize it with: git init Create a .gitignore File To avoid uploading unnecessary files, create a .gitignore file if you haven't already:

Edit the .gitignore file to include files and folders you don’t want to upload (e.g., node_modules/ and .env): node_modules/ .env .DS_Store Commit the Project Files

Create a Repository on GitHub

Go to GitHub and log into your account.
Click on New Repository.
Name your repository and set the visibility (public or private).
Click Create Repository (do not initialize with a README if your local project already has one).

Link Your Local Repository to GitHub

Verify that the remote was added correctly: git remote -v Push the Project to GitHub git push -u origin main If your main branch is named master, use: git push -u origin master

If Below Error Occurs

warning: adding embedded git repository: frontend hint: You've added another git repository inside your current repository. hint: Clones of the outer repository will not contain the contents of hint: the embedded repository and will not know how to obtain it. hint: If you meant to add a submodule, use: hint: hint: git submodule add <url> frontend hint: hint: If you added this path by mistake, you can remove it from the hint: index with: hint: hint: git rm --cached frontend hint: hint: See "git help submodule" for more information.

The warning indicates that there is an embedded Git repository inside your main repository, specifically in the frontend folder. This typically happens when frontend was initialized as a separate Git repository. Here’s how to resolve it: Steps to Remove the Embedded Repository in frontend Remove the Embedded Git Repository from frontend. Run the following command to remove frontend from the Git index (this won’t delete any files in frontend but will remove it from tracking as a separate repository):

Delete the .git Folder in frontend

Navigate to the frontend folder and delete the .git folder to remove the separate Git repository in frontend:

Return to the Main Project Directory After removing the .git folder in frontend, go back to your main project directory: cd .. Add frontend and backend to the Main Git Repository Now, re-add both frontend and backend folders to the Git staging area:

Push the Changes to GitHub

If Below Error Comes

remote: Repository not found. fatal: repository 'https://github.com/your-username/your-repo-name.git' not found

Verify the Repository URL with GitHub CLI or HTTPS To ensure there are no issues with HTTPS authentication, you might want to use SSH if you haven’t already set it up. Otherwise, verify you’re logged in via HTTPS properly. Switch to SSH (if not already) If you’re currently using HTTPS, try switching to SSH for pushing changes to GitHub. Then, test the SSH connection: If SSH is set up correctly, you should see a success message.

Authenticate with GitHub Token

If using HTTPS, GitHub recently switched to using Personal Access Tokens (PAT) instead of passwords. To authenticate via HTTPS with PAT:

Go to GitHub Personal Access Tokens.
Generate a new token with repo permissions.
Use the generated token in place of your password when prompted during git push.

Delete and Re-Add Remote If there’s a configuration issue with the remote, try removing and re-adding it: git remote remove origin git remote add origin https://github.com/your-username/your-repo-name.git After re-adding, try pushing again:

If Below Error Comes

The authenticity of host 'github.com (20.207.73.82)' can't be established. ED25519 key fingerprint is SHA256:+SojshshY8262JJJJ This key is not known by any other names.

git@github.com: Permission denied (publickey). fatal: Could not read from remote repository

The "Permission denied (publickey)" error usually indicates that GitHub is not recognizing your SSH key, or no SSH key is added to your GitHub account. Here’s how to troubleshoot and resolve this issue:

Check if You Have an SSH Key ls -al ~/.ssh You should see files like id_rsa and id_rsa.pub (or id_ed25519 and id_ed25519.pub if using ED25519). If you don’t see these files, you need to generate a new SSH key.

Generate a New SSH Key (If Necessary)

If prompted, press Enter to accept the default location for the key files. When asked for a passphrase, you can either enter one for added security or leave it empty.

Add the SSH Key to the SSH Agent

eval "$(ssh-agent -s)" ssh-add ~/.ssh/id_ed25519 If you used a different name for your SSH key file, replace id_ed25519 with the correct filename.

Add the SSH Key to Your GitHub Account

Copy your SSH public key to the clipboard: If you used a different filename, replace id_ed25519.pub with the correct filename. Go to GitHub SSH Keys Settings in your browser. Click New SSH Key and paste the copied key into the "Key" field. Give it a title and click Add SSH Key. Test the SSH Connection Retry the Git Command git push -u origin main
