validation

When gen.generators includes zod(), valibot() or standardSchema() (no validation library needed), the generated schema validates every write with the generated insert and update schemas. Nothing to install:

import { defineConfig, zod } from "better-supabase/config";

export default defineConfig({ gen: { generators: [zod()] } });

To pass your own schemas, per table, install validation() yourself; it replaces the one the generated schema installed:

import { validation } from "better-supabase";

import { validators } from "./generated.zod.ts";

const betterSupabase = defineSupabase(schema).use(
  validation({
    schemas: {
      ...validators,
      customers: { insert: customerForm, update: customerForm.partial() },
    },
  }),
);

• Inserts and upserts use insert; updates use update.
• Validation runs on app-cased rows, after the other extensions, and its output is what gets written. Transforms such as trimming apply.
• Failures return a validation error (422) with Standard Schema issues. Bulk writes prefix each path with the row index: [1, 'color'].
• Nothing is sent when validation fails.

Any validator that implements Standard Schema works: zod, valibot, arktype, effect schema and more.
