Prevent Uploading Source Paths with .vercelignore on Vercel

Vercel supports configuration required to ignore source files and paths within your project. With a .vercelignore file in your project directory, a source path can be prevented from being uploaded to Vercel.

The syntax of a .vercelignore file matches that of the popular .gitignore file used in ignoring files when uploading to a Git repository.

An example of a .vercelignore file that prevents an /image directory and /private.html file within a project from being uploaded to Vercel would look like this:


An example .vercelignore file.

A typical .vercelignore file assumes all files are allowed and each entry is a pattern to ignore. Alternatively, you may chose to ignore all files and each entry is a pattern to allow. The first step is to add a wildcard /* as the first line in .vercelignore. This will ensure all directories and files in the project root are ignored. The following lines must start with a ! to invert the ignore action and ensure the directory or file is allowed.

# Ignore everything (folders and files) on root only

An example .vercelignore file using the "allowlist" pattern.

Aside from the default exclusions, all files within your project are uploaded to Vercel if no source path is specified to be excluded in a .vercelignore configuration file.

Note: You can find the complete list of files and directories excluded by default in the Vercel documentation.

Worthy of note is that not all uploaded files are served on Vercel.

If Vercel is required to build your project, the non-targeted files are prevented from being deployed and served on Vercel.

The use of a .vercelignore configuration file allows you to keep private files safe and also makes your deployment faster by uploading only the essential files.
