Prisma Generator Express Field Guide Practical guides to shipping Prisma APIs faster with generated routes, OpenAPI, pagination, hooks, and guard features. https://multipliedtwice.github.io/prisma-generator-express/ 2026-08-16T00:00:00+07:00 A whole product API without writing an endpoint: Prisma + generated RPC routes https://multipliedtwice.github.io/prisma-generator-express/articles/generated-prisma-rpc-api/ 2026-08-16T00:00:00+07:00 Build a generated Prisma HTTP API with guarded shapes, caller variants, projection, pagination, and tenant scope. Seven ways to leak a tenant through a query API—and the declarative fix for each https://multipliedtwice.github.io/prisma-generator-express/articles/tenant-query-leaks/ 2026-08-16T00:00:00+07:00 Find tenant-isolation failures in query shapes, hooks, variants, nested reads, scope maps, and dropped guards. force(), true, and the difference between a default and a boundary https://multipliedtwice.github.io/prisma-generator-express/articles/force-and-boundaries/ 2026-08-16T00:00:00+07:00 Understand forced Prisma values, strict positions, merge behavior, validation, scope limits, and direct shape tests. One model, five audiences: caller routing with named and parameterized variants https://multipliedtwice.github.io/prisma-generator-express/articles/caller-routing-variants/ 2026-08-16T00:00:00+07:00 Route public and privileged callers to separate declared Prisma contracts without trusting client-selected headers. When configuration runs out: hooks that narrow, hooks that enrich, hooks that must not exist https://multipliedtwice.github.io/prisma-generator-express/articles/hooks/ 2026-08-16T00:00:00+07:00 Place generated-route hooks at the correct lifecycle boundary and keep authorization, shapes, scope, and transport behavior separate. Projection is a security boundary: select, include, and the relation that carries no scope https://multipliedtwice.github.io/prisma-generator-express/articles/projection-security/ 2026-08-16T00:00:00+07:00 Protect Prisma projections across reads, mutations, nested relations, caller variants, counts, and unguarded paths. Reads at scale: pagination totals, POST reads, and streaming a page before it is complete https://multipliedtwice.github.io/prisma-generator-express/articles/reads-at-scale/ 2026-08-16T00:00:00+07:00 Verify generated pagination, count strategies, POST reads, progressive SSE events, fallbacks, and hook behavior. Writes: forced data, upserts, relation writes, and not deleting the table https://multipliedtwice.github.io/prisma-generator-express/articles/writes/ 2026-08-16T00:00:00+07:00 Guard generated Prisma writes across create, update, bulk operations, upsert, relations, projection, and provider limits. Every error this stack throws, and what actually caused it https://multipliedtwice.github.io/prisma-generator-express/articles/error-reference/ 2026-08-16T00:00:00+07:00 Look up reproduced prisma-guard and prisma-generator-express errors by message, cause, and correction. Silent semantics and testing traps: when no error tells you the shape is wrong https://multipliedtwice.github.io/prisma-generator-express/articles/silent-behaviors/ 2026-08-16T00:00:00+07:00 Diagnose successful requests whose forced values, projections, scope, pagination, counts, or test mode behave unexpectedly.
