# v0.14 -> v0.15 migration guide

# Removed Requests+

As we said before, Requests+ features are totally removed in 0.15.
Passing options won't do anything.

# Removed ApiQueue

After Spawner API release, there are no need in ApiQueue because of duplicated logic:

// <=0.15
import { ApiQueue } from '@apicase/core'

const queue = new ApiQueue()

queue.push(SomeService.doRequest, { url: '/foo' })
queue.push(SomeService.doRequest, { url: '/bar' })
queue.push(SomeService.doRequest, { url: '/baz' })

// 0.15+
import { ApiSpawner } from '@apicase/spawner'

const spawner = new ApiSpawner({
  mode: "queue",
  base: SomeService
})

/* Spawn requests */
spawner.spawn({ url: "/foo" })
spawner.spawn({ url: "/bar" })
spawner.spawn({ url: "/baz" })

So, you have to get rid of ApiQueue in order to ApiSpawner with queue mode.

# Removed ApiService

ApiService is now totally removed from @apicase/core package. Use @apicase/services instead.
