Host the frontend files on a CDN

This guide explains how to upload the JavaScript and CSS files of the Casdoor frontend to a content delivery network (CDN) with a script from the Casdoor repository.

Learning outcomes​

  • Create a storage provider that points to your CDN.
  • Upload the built frontend files with the deployment script.
  • Understand what the script changes.

What you need​

About the script​

The script deployment/deploy_test.go does two things:

  1. It uploads the files under web/build/assets/ to the storage provider. Before Casdoor v4, the directory was web/build/static/.
  2. It rewrites the URLs of the .css and .js files in web/build/index.html, so that they point to the CDN.

The Casdoor backend still serves index.html. The browser then loads the assets from the CDN.

If you install the frontend from the casdoor-web npm package, you don't need this script. Set frontendCdnUrl in app.conf instead.

Create a storage provider​

  1. In the Casdoor admin console, create a storage provider for your object storage.

  2. Set the Domain field to the URL of the CDN, ending with /.

Upload the files​

  1. In deployment/deploy_test.go, set the ID of your provider in the call to GetProvider(). The format is <owner>/<name>.

    func TestDeployStaticFiles(t *testing.T) {
        provider := object.GetProvider("admin/provider_storage_aliyun_oss")
        deployStaticFiles(provider)
    }

  2. Run the script:

    cd deployment
    go test

    When the upload succeeds, the output is:

    PASS
    ok      github.com/casdoor/casdoor/deployment   2.951s
