FAQ

Cross-Origin Isolation

The following Cross-Origin headers must be set for operation.

E.g., SharedArrayBuffer is required in WebPaint.

NameValue
Cross-Origin-Opener-Policysame-origin
Cross-Origin-Embedder-Policyrequire-corp

These header entries are automatically set during development via server middleware and Vite server options.

For deployment on GitHub Pages or similar hosting providers where headers cannot be set, a fallback can be used: https://github.com/gzuidhof/coi-serviceworker

This can be activated via the environment variable COI_WORKER = true.
