894cb531d1 feat(docs): add resumable WebSockets + Edge Functions troubleshooting guides (#46178)
## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Docs update (new guides + follow-up documentation fix from review
feedback).

## What is the current behavior?

There was no consolidated docs example for resumable WebSockets with
Edge Functions, and no dedicated troubleshooting guide for worker
timeouts / WebSocket drops.

## What is the new behavior?

- Adds a resumable WebSockets guide for Edge Functions, including:
  - session persistence
  - event replay
  - idempotency pattern and schema examples
  - client/server example flow
- Adds an Edge Functions troubleshooting guide for worker timeouts and
WebSocket drops.
- Updates docs navigation to surface the new guides.
- Follow-up fix from review feedback: the browser client example now
stores `sessionId` and `lastEventId` in `sessionStorage` (instead of
`localStorage`).

## Additional context

- Branch has been updated with latest `origin/master`.
- This PR remains documentation-focused; no production runtime code
changes were introduced.

## Summary by CodeRabbit

* **Documentation**
* Added a guide on resumable WebSockets covering session persistence,
event replay, idempotency patterns, SQL schema examples, and
client/server usage.
* Added a troubleshooting guide on Edge Functions worker timeouts and
WebSocket drops with scenarios, symptoms, and practical workarounds.
* Enhanced WebSocket docs with a production note on worker lifecycle and
keeping runtime promises open to avoid premature shutdown.
  * Navigation updated to surface the new guides.

Supabase Reference Docs

Maintainers

If you are a maintainer of any tools in the Supabase ecosystem, you can use this site to provide documentation for the tools & libraries that you maintain.

Versioning

All tools have versioned docs, which are kept in separate folders. For example, the CLI has the following folders and files:

  • cli: the "next" release.
  • cli_spec: contains the DocSpec for the "next" release (see below).
  • cli_versioned_docs: a version of the documentation for every release (including the most current version).
  • cli_versioned_sidebars: a version of the sidebar for every release (including the most current version).

When you release a new version of a tool, you should also release a new version of the docs. You can do this via the command line. For example, if you just released the CLI version 1.0.1:

npm run cli:version 1.0.1

DocSpec

We use documentation specifications which can be used to generate human-readable docs.

  • OpenAPI: for documenting API endpoints.
  • SDKSpec (custom to Supabase): for SDKs and client libraries.
  • ConfigSpec (custom to Supabase): for configuration options.
  • CLISpec (custom to Supabase): for CLI commands and usage.

The benefit of using custom specifications is that we can generate many other types from a strict schema (eg, HTML and manpages). It also means that we can switch to any documentation system we want. On this site we use Next.js, but on Supabase's official website, we use a custom React site and expose only a subset of the available API for each tool.
