Recipes

Practical oRPC recipes for testing and mocking, validation, monorepos, publishing a typed client to npm, faster SSR, and fixing common TypeScript errors.

Short guides for common tasks and problems.

• Testing and Mocking: test procedures directly and mock them.
• Validation Customization: turn off validation or shape validation errors.
• Monorepo Setup: keep types end to end across packages.
• Publish Client to NPM: ship your client as a typed SDK.
• Optimizing SSR: skip HTTP when rendering on the server.
• Dedupe Middleware: avoid repeating expensive middleware work.
• No Throw Literal: why oRPC expects Error instances.
• Exceeds the Maximum Length Problem: fix the error for very large router types.
