`zod` Function Definitions in JavaScript Classes

#javascript #typescript #webdev

Overview

Wasn't able to find this clearly stated on the internet. Here's how you use the zod.function() system in a JavaScript class.

I work for Akkio, where I'm building out a no-code predictive AI platform. If you're looking to harness the power of AI without needing a data scientist, give us a try!

The Working Solution

class ClassName {
  request = z
    .function()
    .args(
      z.string(),
      z.object({
        temperature: z.number().default(0),
        model: z.nativeEnum(MODELS).default(MODELS.STANDARD),
        schema: z.instanceof(ZodSchema),
      })
    )
    .returns(z.promise(z.string()))
    .implement(async (prompt, options) => {
      // ...
    })
