Supabase Development in Wrexham

Building on Supabase for Wrexham organisations, where the browser talks to the database directly. There is no server layer deciding what each user may see unless you write one, so row-level security is not a hardening step applied later — it is the entire access control model, and an application without it is simply open.

Why this comes up

The problem

The front end queries tables directly and no row-level policies restrict what any signed-in user can read.

What you get

What we deliver

  • Row-level security enabled on every table from the start, not retrospectively
  • Policies written per table and tested by attempting access that should fail
  • Server-side logic placed in functions where the client should not decide
  • Generated types used so the schema and the application stay in agreement
  • Migrations managed in version control rather than changed through the dashboard
  • Realtime subscriptions scoped, since these respect policies but still cost connections

Supabase Development in Wrexham — common questions

Why is security the architecture here?
Because there is nothing between the client and the database. In a conventional application the server decides what to return; here the query comes from the browser, so the only thing preventing one user reading another's data is the policy on the table.
How should policies be tested?
By asserting that forbidden reads fail. A policy tested only by the developer signing in as themselves proves nothing, whereas a test that signs in as one user and confirms they cannot see another's rows is the check that actually matters.
When do we need server-side functions?
When the client should not be trusted with the logic. Anything involving a secret, a third-party call or a rule the user could otherwise bypass belongs in a database function or an edge function rather than in code running on their machine.
Should schema changes go through the dashboard?
Not for anything you intend to keep. Changes made through the interface exist in one environment with no history, so migrations held in version control are what allow the schema to move between environments and be reviewed like the rest of the code.
