How to Integrate Git with V0

With your V0 project open, look at the left-side panel icons. You will see icons for Design, Git, Connect, Vars, and Settings. Click the Git icon (it looks like a branching diagram) to open the Git panel. If you have not connected a GitHub account yet, V0 will show a prompt to authorize GitHub — click it and follow the OAuth flow to grant V0 permission to create repositories and push code on your behalf. The authorization is scoped to the permissions V0 needs: reading your profile, creating repositories, and pushing branches. You are not giving V0 access to all your existing repositories in a destructive way. Once connected, the Git panel shows your current project's repository status. If this is a brand-new V0 project that has never been pushed to GitHub, you will see a button to create a new repository. Give it a descriptive name — something like `my-startup-landing` or `portfolio-v2`. V0 will create the repository on GitHub under your account (or an organization you select) and push your current project code as the initial commit. This initial push goes to the main branch and represents your baseline.

This step is about understanding V0's branching behavior so you do not get confused when you look at GitHub. V0 never commits AI-generated changes directly to your main branch after the initial push. Instead, every session of AI edits creates a new branch named `v0/main-{unique-hash}`, for example `v0/main-a1b2c3d4`. This is intentional and actually a best practice: it gives you a chance to review exactly what the AI changed before those changes affect your live deployment. When you are done editing in V0 and want to publish your changes, go to the Git panel and click the Push button (or similar — the label may be 'Commit & Push' or 'Push to GitHub' depending on the V0 version). V0 will commit all current changes to the v0/main branch and push to GitHub. You will then see a notification or a link to open a pull request on GitHub. Go to your GitHub repository, click the 'Compare & pull request' button that appears for your v0/main-{hash} branch, review the diff to see exactly what changed, and merge it into main when you are satisfied. Vercel will then pick up the merge and trigger a new deployment automatically. This workflow gives you a clean audit trail of every AI edit session as a separate pull request.

Now that your code is on GitHub, you can connect Vercel for automatic deployments. Go to vercel.com and log in (sign in with GitHub for the smoothest experience). Click the 'Add New Project' button on your dashboard. Vercel will prompt you to import a Git repository — browse your GitHub repositories and select the one V0 just created. If you do not see it listed, click 'Adjust GitHub App Permissions' to grant Vercel access to the new repository. Vercel will auto-detect that this is a Next.js project (V0 generates Next.js code) and pre-fill the build settings: Build Command `npm run build`, Output Directory `.next`, Install Command `npm install`. These defaults are correct — you generally do not need to change them for a standard V0-generated project. Click 'Deploy' and Vercel will clone your repository and run the first build. This initial deploy takes 30-90 seconds. Once complete, Vercel provides you with a unique deployment URL like `your-project.vercel.app`. From this point forward, every time you push to your main branch on GitHub (by merging a pull request from V0), Vercel will automatically detect the push and run a new build. Your live URL always stays up to date with whatever is in main. Vercel also creates preview deployments for every pull request, so you can see exactly how the V0 changes will look on a live URL before you merge them.

One of the less obvious aspects of the V0 + Git workflow is what happens when someone makes manual changes to the code outside of V0 — for example, a developer edits a file directly in VS Code and pushes to GitHub. V0 is not automatically aware of those changes. If you continue generating in V0 without syncing, your V0 project and your GitHub repository can get out of sync, leading to merge conflicts. To pull the latest code from GitHub into V0, open the Git panel and look for a 'Pull' or 'Sync' option. This fetches the latest commits from your main branch and updates the V0 project to match. Always do this before starting a new round of AI edits if you or a teammate has made manual code changes in the meantime. For teams, establish a clear convention: manual code changes go to a branch, get reviewed via pull request, merge to main, then everyone (including V0 users) syncs from main before starting new work. This prevents the painful situation of V0 overwriting manual improvements with an older version of the code. If you are working solo, this is less of a concern — but it is still good practice to pull before you prompt. If you run into a merge conflict (V0 and GitHub have different versions of the same file), the safest resolution is to use GitHub's conflict editor in the browser to manually pick which version of each conflicting section to keep, then merge the resolution commit. After that, pull in V0 again to get the clean state.

V0 generates a standard Next.js .gitignore when it creates your project, but it is worth understanding what it includes and why. The .gitignore file tells Git which files to never commit to the repository. For Next.js projects, the most important exclusions are: `.env.local` (your local environment variables), `.env` (any environment file with secrets), `node_modules/` (the installed dependencies folder, which can be hundreds of megabytes), and `.next/` (the build output, which Vercel generates fresh on every deploy). If V0's generated .gitignore is missing any of these, you should add them. To edit the .gitignore in V0, open the file browser (usually accessible via the code editor in Dev Mode, or you can push to GitHub and edit the file directly there). The most critical rule: NEVER commit a file containing API keys, database passwords, or other secrets. If you accidentally commit a secret, rotate the key immediately — deleting the commit from history is complicated and the key should be considered compromised. For environment variables in your Vercel deployment, add them in the Vercel Dashboard under Settings → Environment Variables, not in files that get committed to GitHub. V0-generated API routes use `process.env.VARIABLE_NAME` to read these at runtime, keeping secrets out of your source code entirely.
