deriveDataLayer() function

Derive the data-layer config from an emitted contract.

Signature:

export declare function deriveDataLayer(input: DeriveOptions): DerivedDataLayer;

Parameters

Returns:

DerivedDataLayer

Config for dataLayer() and the individual middlewares.

Exceptions

When scope names a model the contract does not define.

Remarks

This replaces the Prisma 7 generator that wrote SOFT_DELETE_MODELS, AUTHORSHIP_MODELS and the rest into src/generated. Prisma Next has no custom-generator protocol and does not need one: the contract already names every model, field and physical column, so the same config is a lookup rather than a build step, and nothing can go stale against the schema.

Membership is by convention, which is what softDelete = "auto" and authorship = "auto" meant. Everything is keyed by **physical table**, because that is what a statement names — resolving a table back to a model at query time would have to go through the contract's roots, which is keyed by bare table name only while that name is unique across namespaces.

Example

const layer = deriveDataLayer({
    contract: contractJson,
    scope: { Portfolio: { portfolio: ['id'] } },
});
