Handlers you fill from tests

Return an empty typed payload from each handler by keeping parser on its default 'data'. Each test supplies the response body it needs, and the type comes from @kubb/plugin-ts.

kubb.config.ts

import { defineConfig } from 'kubb/config'
import { pluginTs } from '@kubb/plugin-ts'
import { pluginMsw } from '@kubb/plugin-msw'

export default defineConfig({
  input: './petStore.yaml',
  output: { path: './src/gen', clean: true },
  plugins: [
    pluginTs({ output: { path: 'types', mode: 'directory' } }),
    pluginMsw({
      output: { path: 'handlers', mode: 'directory' },
      parser: 'data',
    }),
  ],
})

Output example

src/gen/handlers/getPetByIdHandler.ts

import type { GetPetByIdResponse } from '../types/GetPetById'
import { http } from 'msw'

export function getPetByIdHandler(data?: GetPetByIdResponse | ((info: Parameters<Parameters<typeof http.get>[1]>[0]) => Response | Promise<Response>)) {
  return http.get(`/pet/:petId\\:search`, function handler(info) {
    if (typeof data === 'function') return data(info)

    return new Response(JSON.stringify(data), {
      status: 200,
      headers: { 'Content-Type': 'application/json' },
    })
  })
}

usage.ts

import { setupServer } from 'msw/node'
import { getPetByIdHandler } from './src/gen/handlers/getPetByIdHandler'

// Each test supplies its own payload for the typed response.
const server = setupServer(getPetByIdHandler({ id: 1, name: 'Rex' }))
