    For the language models, Genkit provides the concept of Flows. A flow basically combines a prompt with a set of "tools" or actions that the llm can take. Like other frameworks in this space ZOD is used to provide schema information for both the input and output of flows and actions.
  • Using Arktype in Place of Zod - How to Adapt Parsers
    4 projects | dev.to | 12 Jun 2024
    Ever since I started using Zod, a TypeScript-first schema declaration and validation library, I've been a big fan and started using it in all my projects. Zod allows you to ensure the safety of your data at runtime, extending TypeScript’s type-checking capabilities beyond compile-time. Whenever I need to validate data from an outside source, such as an API, FormData, or URL, Zod has been my go-to tool.

  • Serverless, the Intersection of Technology and People

    Once you've leaped into thinking as a serverless problem solver, it makes a lot of sense to standardize some tooling and frameworks. The old adage right tool for the job is what I like about this layer of the pyramid. For instance, if a problem requires flexibility in data and your team enjoys validating schema with Joi then you might use TypeScript with a Node.js runtime with your lambdas. If you prefer the developer experience and small footprint and simplicity of Go then use the Go 1.x runtime. You might find you don't need "compute" at all, so using intrinsic functions in State Machines might be plenty.

    I'm using Joi on my server to validate form input, do you think I still need honeypot fields? It sounds like it might be worth looking into IP rate limiting as well, I don't think Joi can help with that.

  • JSON and scehama validator libraries for Node

    Yup's API is heavily inspired by Joi, but leaner and built with client-side validation as its primary use-case. Yup separates the parsing and validating functions into separate steps. cast() transforms data while validate checks that the input is the correct shape. Each can be performed together (such as HTML form validation) or seperately (such as deserializing trusted data from APIs).

    Yup is a Javascript object schema validator: it lets you define a schema to describe how a valid object should look like, and allows you to validate an object using this schema. If you know Joi, Yup is heavily inspired by it, except it relies on client-side validation as its primary use-case.
