Optional exposeHeaders: string[]

The value of "Access-Control-Expose-Headers" CORS header.

Optional maxAge: number

The value of "Access-Control-Max-Age" CORS header.

Optional credentials: boolean

The value of "Access-Control-Allow-Credentials" CORS header.

Usage

import { App } from 'https://deno.land/x/toruk/mod.ts'
import { cors } from 'https://deno.land/x/toruk/middlewares/mod.ts'

new App({
  routes: [ /* ... */ ],
  use: [
    cors({
      origin: 'https://example.com',
      allowHeaders: ['X-Custom-Header', 'Upgrade-Insecure-Requests'],
      allowMethods: ['POST', 'GET', 'OPTIONS'],
      exposeHeaders: ['Content-Length', 'X-Kuma-Revision'],
      maxAge: 600,
      credentials: true,
    }),
  ]
}).serve()

Zod 3rd

Validate the request body using Zod. This middleware does not propagate over route nesting.

If used with Swagger UI middleware, it will provide body types.

🚧 WIP

This feature is under development.

Usage

import { App } from 'https://deno.land/x/toruk/mod.ts'
import { zod } from 'https://deno.land/x/toruk/middlewares/mod.ts'
import { z } from 'https://deno.land/x/zod/mod.ts'

const schema = z.object({
  name: z.string(),
  age: z.number(),
})

new App({
  routes: [{
    path: '/',
    handler: ({ body }) => new Response('Hello ' + body.name + '!'),
    use: [
      zod({
        schema,
        onError: ({ error }) => {
          // Handle the error
        }
      })
    ]
  }],
}).serve()

With separated handler:

import type { Handler } from 'https://deno.land/x/toruk/mod.ts'
import type { UseZod } from 'https://deno.land/x/toruk/middlewares/mod.ts'
import { z } from 'https://deno.land/x/zod/mod.ts'

const schema = z.object({
  name: z.string(),
  age: z.number(),
})

export const handler: Handler<'/', [ 
    UseZod<typeof schema>
  ]> = async ({ body }) => {
  return new Response('Hello ' + body.name + '!')
}
