Neon CLI command: git

Summary: The Neon CLI git command connects git branch switches to Neon checkout. It installs a git post-checkout hook so that switching git branches checks out the mapped Neon branch, with subcommands to install and remove the hook (install, uninstall), run the sync by hand (sync), inspect the current state (status), and prune stale branch mappings (cleanup).

Neon CLI command: git

Keep your Neon branch in sync with the git branch you have checked out

The git command connects your git workflow to Neon branching. After you install its git hook, switching git branches with git checkout also checks out the Neon branch mapped to that git branch, so your application code and its database branch stay in sync. Under the hood it delegates to neon checkout and records the git-to-Neon mapping in your local context file.

Coming soon: Preview

The neon git command group is in preview. The commands and their behavior may change.

Before you install the hook, link a Neon project at your repository root with neon link or neon checkout. The hook reads the .neon context file at the repository root, so the project link has to live there.

Subcommands: cleanup, install, status, sync, uninstall

neon git install

Installs a managed post-checkout git hook that runs neon git sync whenever you switch branches with git checkout. The hook honors your configured git hooks directory and won't overwrite an existing unmanaged post-checkout hook.

The command requires a project already linked at the repository root's own .neon file. If none is linked, install stops and tells you to run neon link or neon checkout <branch> there first.

Bash

neon git install [options]

Bash

neon git install

text

Git → Neon sync installed. `git checkout <branch>` will now check out the mapped Neon branch.
Hook: /path/to/your/app/.git/hooks/post-checkout

neon git status

Shows your current git branch, whether the hook is installed, whether sync-on-checkout is enabled, the Neon branch mapped to the current git branch, and all recorded mappings. Use --output json or --output yaml for scripting.

Bash

neon git status [options]

Bash

neon git status

text

GitBranch         main
HookInstalled     false
FollowOnCheckout  false
MappedNeonBranch  (unmapped — will derive on next sync)
Mappings          (none)

neon git sync

Checks out the Neon branch mapped to the current git branch. This is the command the installed hook runs on every git checkout, and you can also run it by hand. If no mapping exists yet, sync derives a Neon branch name from the current git branch and checks it out, then saves the resulting mapping so later checkouts of that git branch stay stable. The Neon branch has to exist already: sync doesn't create it, so a git branch with no matching Neon branch reports Branch <name> not found. Pass --create to create it. unless a checkout.before hook maps it to an existing branch. A detached HEAD has no git branch, so sync skips it.

Pass --pull to run git pull --ff-only before syncing, so committed files such as migrations match the branch before any checkout.after hook runs. A pull failure warns and sync continues. Pass --no-env-pull to skip pulling the branch's Neon environment variables into a local .env after sync.

Bash

neon git sync [options]

Option	Description	Type	Default	Required
`--env-pull`	Pull the branch's Neon env vars into a local .env after sync. On by default.	boolean	`true`	No
`--pull`	Run `git pull --ff-only` before syncing so local files (incl. migration files) match the branch before any checkout.after migration runs. Without the flag, prompts when run manually in a TTY and skips in the hook / CI.	boolean	—	No
`--quiet`	Suppress sync's own routine status lines (git pull result, detached HEAD notice). Warnings and the delegated checkout's own output are unaffected. Used by the installed git hook.	boolean	`false`	No

Bash

neon git sync --no-pull

text

Checked out branch br-billing-a1b2c3d4 on project polished-snowflake-12345678 (org org-example-12345678). Updated /path/to/your/app/.neon.
Pulled 3 Neon variables into /path/to/your/app/.env.local: DATABASE_URL, DATABASE_URL_UNPOOLED, NEON_BRANCH

neon git cleanup

Removes git-to-Neon mappings whose local git branch no longer exists. By default it only prunes the mappings. Add --prune-neon-branches to also delete the orphaned Neon branches, which never touches the default or a protected branch. Deleting Neon branches prompts for confirmation unless you pass --yes.

Bash

neon git cleanup [options]

Option	Description	Type	Default	Required
`--prune-neon-branches`	Also delete the orphaned Neon branches (never the default or a protected branch).	boolean	`false`	No
`--yes`	Skip the confirmation prompt before deleting Neon branches.	boolean	`false`	No

Prune stale mappings only:

Bash

neon git cleanup

text

Pruned 1 stale mapping(s) from .neon:
  feature/billing → feature/billing
These Neon branch(es) are no longer mapped and were not deleted: feature/billing. Delete them with `neon branches delete <name>`, or run `neon git cleanup --prune-neon-branches` next time before a mapping-only cleanup.

Prune stale mappings and delete their Neon branches without a prompt:

Bash

neon git cleanup --prune-neon-branches --yes

neon git uninstall

Removes the managed post-checkout hook installed by neon git install and turns off sync-on-checkout. If the post-checkout hook isn't the one Neon manages, uninstall leaves it in place and only clears the sync flag.

Bash

neon git uninstall [options]

Bash

neon git uninstall

text

Removed the neon git post-checkout hook. Git → Neon sync is off.
