Security And Autosave
Security and autosave architecture for safe content handling and reliable persistence workflows.
Security model
- Sanitize inbound and outbound HTML paths.
- Restrict unsafe tags/attributes at the editor boundary.
- Apply consistent rules in both React and web component integrations.
Autosave model
- Trigger save logic from content-change events.
- Debounce saves to avoid write amplification.
- Persist per document id to prevent cross-document overwrite.
Recommended strategy
- Define an allowlist-based sanitization policy.
- Normalize pasted/imported HTML before render.
- Enable debounced autosave and persist revision timestamps.
- Restore draft content only for the same document scope.
Failure handling
- Show save status (
saving,saved,error) in UI. - Retry failed saves with bounded backoff.
- Keep unsaved draft state local until remote persistence succeeds.
API Surface
| Surface | Type | Notes |
|---|---|---|
security runtime config | Config API | Controls sanitize-on-paste/input policy and HTML safety behavior |
autosave runtime config | Config API | Controls enablement, interval/debounce, storage provider/keying |
| Content change events/callbacks | Integration API | Trigger persistence pipelines and save-state UX |
setConfig({...}) / React runtime props | Update API | Applies security/autosave settings per editor instance |
Config Matrix
| Area | Key Option | Purpose |
|---|---|---|
| Security | sanitizer/allowlist rules | prevent unsafe HTML |
| Security | paste/import normalization | block malformed DOM |
| Autosave | debounce interval | reduce save churn |
| Autosave | storage adapter | local/remote persistence |
| Autosave | document keying | isolate drafts |
Validation Checklist
- Sanitization rules remove disallowed constructs predictably.
- Autosave does not fire excessive writes under rapid typing.
- Restored drafts match the correct document id.
- Save failure state remains non-blocking for editing.
