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:
.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 /* !api !vercel.json !*.html
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.
