Arguments

How to pass arguments to functions

Args

To accept arguments we need to use .args which takes a zod object so we can validate the input.

import { middleware } from 'kavi/server'
import z from 'zod'

middleware
  .args(z.number())
  .call((args, ctx) => ...)

Since .args only takes one argument we can use z.tuple() or z.object() to get more arguments.

Example

server.ts
import { middleware } from 'kavi/server'
import z from 'zod'

export const router = {
  add: middleware
    .args(z.tuple([
      z.number(),
      z.number()
    ]))
    .call(([a, b]) => {
      return a + b
    })
}

+page.svelte
<script lang="ts">
  import { api } from '$lib/kavi/client'
</script>

<button onclick={async () => {
  await api.add([1, 2]).ok()
}}>
  Add two numbers on the server
</button>
