Workers Sites configuration

Use Workers Static Assets Instead

You should use Workers Static Assets to host full-stack applications instead of Workers Sites. Do not use Workers Sites for new projects.

Workers Sites require the latest version of Wrangler ↗.

wrangler.toml

There are a few specific configuration settings for Workers Sites in your wrangler.toml file:

• bucket required

  • The directory containing your static assets, path relative to your wrangler.toml. Example: bucket = "./public".

• include optional

  • A list of gitignore-style patterns for files or directories in bucket you exclusively want to upload. Example: include = ["upload_dir"].

• exclude optional

  • A list of gitignore-style patterns for files or directories in bucket you want to exclude from uploads. Example: exclude = ["ignore_dir"].

To learn more about the optional include and exclude fields, refer to Ignoring subsets of static assets.

Note

If your project uses environments, make sure to place site above any environment-specific configuration blocks.

Example of a wrangler.toml:

name = "docs-site-blah"

[site]
bucket = "./public"

[env.production]
name = "docs-site"
route = "https://example.com/docs*"

[env.staging]
name = "docs-site-staging"
route = "https://staging.example.com/docs*"

Storage limits

For very exceptionally large pages, Workers Sites might not work for you. There is a 25 MiB limit per page or file.

Ignoring subsets of static assets

Workers Sites require Wrangler ↗ - make sure to use the latest version.

There are cases where users may not want to upload certain static assets to their Workers Sites. In this case, Workers Sites can also be configured to ignore certain files or directories using logic similar to Cargo's optional include and exclude fields ↗.

This means that you should use gitignore semantics when declaring which directory entries to include or ignore in uploads.

Exclusively including files/directories

If you want to include only a certain set of files or directories in your bucket, you can add an include field to your [site] section of your wrangler.toml file:

[site]
bucket = "./public"
include = ["included_dir"] # must be an array.

Wrangler will only upload files or directories matching the patterns in the include array.

Excluding files/directories

If you want to exclude files or directories in your bucket, you can add an exclude field to your [site] section of your wrangler.toml file:

[site]
bucket = "./public"
exclude = ["excluded_dir"] # must be an array.

Wrangler will ignore files or directories matching the patterns in the exclude array when uploading assets to Workers KV.

Include > exclude

If you provide both include and exclude fields, the include field will be used and the exclude field will be ignored.

Default ignored entries

Wrangler will always ignore:

• node_modules
• Hidden files and directories
• Symlinks
