tiny-schema-validator VS zod

Take a look at tiny-schema-validator . Totally not sponsered

It's an NPM package tiny-schema-validator

tiny-schema-validator is a very small library that makes sending data between client and server a breeze, with close to perfect DX.

shameless plug https://github.com/5alidz/tiny-schema-validator

tiny-schema-validator can infer data types from your schema, and it has a `traverse` function to create arbitrary data-shape from the schema.

Express.js does not have built-in request validation. You have to use a library like Zod.

Here is the code for the request and response schemas. I'm using zod to do this on the front end:

Validation using Zod.

Zod is the most famous validation library in the TypeScript ecosystem. With Zod, you create a schema and validate your data according to the schema. Observe the schema below:

IMO Zod is much easier to understand than io-ts, the counterpart to fp-ts: https://zod.dev/

Here’s a similar example in TypeScript that utilizes Zod to validate the output generated by an LLM:

Zod is a powerful tool for your data. It's a TypeScript-first library that helps you define and check the shape of your data. Think of it as setting rules for your data and then making sure the data matches those rules before you use it.

Encore.ts, as the name suggests, is designed from the ground up for TypeScript. But you can't actually run TypeScript: it first has to be compiled to JavaScript, by stripping all the type information. This means run-time type safety is much harder to achieve, which makes it difficult to do things like validating incoming requests, leading to solutions like Zod becoming popular for defining API schemas at runtime instead.

Formik + Zod: Similar to Yup, Zod is a schema validation library gaining traction for its developer-friendly API and robust type inference capabilities. https://zod.dev/

Zod is a powerful TypeScript-first schema declaration and validation library with static type inference for TypeScript applications, which allows you to define the expected structure (schema), data types, and validation rules for your application's inputs.
