🔹 Steps to Resolve Merge Conflicts

1. When a Conflict Happens

• You’ll see an error after git merge, git pull, or a PR merge attempt.
  Example:

Auto-merging app.js
CONFLICT (content): Merge conflict in app.js
Automatic merge failed; fix conflicts and then commit the result.

2. Check the Conflicted Files

git status

You’ll see files marked as unmerged.

3. Open the File and Look for Conflict Markers

Git marks the conflicting areas like this:

<<<<<<< HEAD
console.log("Hello from main branch");
=======
console.log("Hello from feature branch");
>>>>>>> feature-branch

• HEAD → current branch (where you’re merging into).

• feature-branch → the branch being merged.

4. Manually Resolve the Conflict

Choose one version, or combine both.
Example (resolved):

console.log("Hello from both branches!");

5. Mark the Conflict as Resolved

git add app.js
git commit

(Or use git commit -m "Resolved merge conflict in app.js").

6. Continue Workflow

• If you were in the middle of a rebase, run:

git rebase --continue

• If you were merging, just commit as above and push.

🔹 Tips & Best Practices for Avoiding Conflicts

1. Pull latest changes (git pull origin main) before starting new work.

2. Commit often with small, focused changes.

3. Use feature branches instead of working directly on main.

4. Communicate with teammates when working on the same file/module.

5. Use tools for easier resolution:

   • IDEs: IntelliJ, VS Code (highlight conflicts).

   • GUI: GitKraken, SourceTree.

🔹 Example Workflow (Resolving a Conflict)

git checkout main
git pull origin main
git merge feature/login   # conflict happens

# open conflicted file(s) and fix them

git add .
git commit -m "Resolved merge conflict between main and feature/login"
git push origin main

✅ In short:

To resolve a merge conflict, you open the conflicted file(s), edit between <<<<<<< and >>>>>>>, keep the correct version (or merge both), stage the changes (git add), and then commit.
