What this source can teach
Use this source to understand a platform convention and the setting it was designed for.
- Start with the original. Open the source and find the guidance or example relevant to your task.
- Trace the connection. Use the claim notes below to see how this site applies the source to specific patterns.
- Check the setting. Compare the source's platform, people, and constraints with your own decision.
Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Offline mobile retry | Choose offline mobile retry when a mobile action should be preserved and retried after connection loss, flaky network, app backgrounding, or policy-limited connectivity. | The UI never reports server success for a mobile action that is only saved locally or queued. | Supports deferring synchronization work until stable network connectivity returns. |
| Sync state | Choose sync state when local and remote copies both matter and their reconciliation status affects trust, next action, or data integrity. | The sync surface never upgrades local saved or queued work to synced until the remote system confirms acceptance. | MDN supports deferring synchronization work to a service worker until stable network connectivity exists. |
Comparisons supported by this source
- Offline mobile retry vs offline state vs retry vs sync state vs pull to refresh vs fallback path
Supports deferring synchronization work until stable network connectivity returns.
- Sync state vs offline state vs progress bar vs error state
MDN supports deferred synchronization work that runs later in a service worker when stable network connectivity exists.
Evidence Role
This source is treated as platform-guideline evidence. Its value comes from the specific claims and setting described above.
