Overview
A backend is JavaScript code that allows Static CMS to communicate with a service that stores content - typically a Git host like GitHub or GitLab. It provides functions that Static CMS can use to do things like read and update files using API's provided by the service.
Backend Configuration
Individual backends provide their own configuration documentation, but there are some configuration options that are common to multiple backends. A full reference is below. Note that these are properties of the backend
field, and should be nested under that field.
Name | Type | Default | Description |
---|---|---|---|
name | 'git-gateway' | 'github' | 'gitlab' | 'bitbucket' | 'gitea' |'test-repo' | 'proxy' | The backend git provider | |
repo | string | Required for github , gitlab , gitea and bitbucket backends. Ignored by git-gateway . Follows the pattern [org-or-username]/[repo-name] | |
branch | string | main | Optional. The branch where published content is stored. All CMS commits and PRs are made to this branch |
api_root | string | GitHubhttps://api.github.com GitLab https://gitlab.com/api/v4 Bitbucket https://api.bitbucket.org/2.0 Gitea https://try.gitea.io/api/v1 | Optional. The API endpoint. Only necessary in certain cases, like with GitHub Enterprise or self-hosted GitLab |
site_domain | string | location.hostname On localhost cms.netlify.com | Optional. Sets the site_id query param sent to the API endpoint. Non-Netlify auth setups will often need to set this for local development to work properly |
base_url | string | GitHub or Bitbuckethttps://api.netlify.com GitLab https://gitlab.com Gitea https://try.gitea.io | Optional. OAuth client hostname (just the base domain, no path). Required when using an external OAuth server or self-hosted GitLab/Gitea |
auth_endpoint | string | GitHub or Bitbucketauth GitLab oauth/authorize | Optional. Path to append to base_url for authentication requests. |
cms_label_prefix | string | cms/ | Pull (or Merge) Requests label prefix when using editorial workflow. Optional. |
Creating a New Backend
Anyone can write a backend, but the API is not yet finalized and documented. If you would like to write your own backend for a service that does not have one currently, Static CMS recommends using the GitHub backend as a reference for API and best practices.
