Miranda Limonczenko 86f3a98399 fix(docs): stop reporting guide 404s to Sentry, redirect missing paths (#50279)
Closes DOCS-1388

## Problem

Expected guide-path 404s were reported to Sentry as errors. They made up
roughly 246k events and nearly all Docs volume, with 0 users impacted.

The cause is a type check that never matched.
`getGuidesMarkdownInternal` tested `error.cause instanceof
FileNotFoundError`, but `GuideModelLoader.fromFs` rethrows
`FileNotFoundError` directly and sets `cause` to the underlying `ENOENT`
error. Every missing guide path fell through to the `else` branch and
hit `Sentry.captureException`.

Nine storage section paths and `database/postgrest` also 404 in
production. They are section `url` values in the nav config with no
landing page and no redirect. They are not reachable from the sidebar,
because a nav item with children renders as an accordion button, so the
traffic is inbound links and crawlers.

## Solution

- Check the error itself as well as its cause, so expected 404s take the
quiet branch.
- Add `ignoreErrors` for `FileNotFound` to `sentry.server.config.ts`,
matching the filtering the client config already does.
- Redirect nine storage section paths to their first child page,
following the existing `storage/cdn` and `storage/uploads` pattern.
- Redirect `database/postgrest` to the Data API guide. The path has no
git history, so its 27k hits are external inbound links.
- Add the missing leading slash to the `storage/access-control`
destination. It resolves correctly today, so this is a cleanup, not a
fix.

## Redirect previews

Redirects are served by the `www` config, so the **Redirect** column
uses the www preview. The www preview cannot render `/docs/**` pages, so
each link lands on a 404 after the hop. That is expected. Check the
`Location` header, or use the **Destination** column to confirm the page
itself.

All eleven return `308` on the www preview with the `Location` shown in
the Destination column. Every destination returns `200`.

## Manual testing

1. Open any **Redirect** link above. The URL changes to the Destination
path, confirming the redirect fires.
2. Open any **Destination** link. The page renders.
3. Confirm the sources 404 on production today, for example
`https://supabase.com/docs/guides/storage/production`.
4. On the [docs
preview](https://docs-git-docs-sentry-404s-and-guide-redirects-supabase.vercel.app/docs/guides/storage/schema),
request a missing guide path and check the deployment logs. The line
reads `Could not read Markdown at path`, not `Error processing Markdown
file at path`. The second form is the branch that calls
`Sentry.captureException`.

Community & Support

  • Community Forum. Best for: help with building, discussion about database best practices.

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Envoy is a cloud-native, high-performance edge and service proxy.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
