import { defineServer, defineEventInterceptor } from '@privyid/nhp/core'

export default defineServer([
  {
    name      : 'bin',
    baseUrl   : '/api/bin',
    targetUrl : 'https://httpbin.org',
    onProxyReq: defineEventInterceptor((proxyEvent, event) => {
      const token = getCookie(event, 'oauth/token')

      if (token)
        setHeader(proxyEvent, 'Authorization', `Bearer ${token}`)
    }),
  },
])

    name          : 'force-download',
    baseUrl       : '/force/download',
    proxyType     : 'dynamic',
    allowFrom     : ['my.cdn.com', 's3.amazon.com'], // or using string with delimeter ;

    baseUrl  : '/api/server-b',
    // ...
    // Using local json
    schemaUrl: './path/doc.json',
  },
  {
    name     : 'server-a',
    baseUrl  : '/api/server-a',
    // ...
    // Using remote schema
    schemaUrl: 'http://server-a.dev/swagger/doc.json',
