Concept for json api deserializer fetch wrapper.

fetch_json.js

api_config = {
  base_url: 'http://localhost:8065/api/v3',
  defaluts: { // if none passed here then use JSON.parse()
    success_deserializer: successJsonApiDerserializer,
    error_deserializer: errorJsonApiDerserializer,
    // has the same defaults as fetch
  },
  resources: {
    all_team_listings: {
      endpoint: 'teams/all_team_listings',
      // takes anything that fetch takes as options
      // uses default deserializers
    },
    channels: {
      endpoint: 'teams/${team_id}/channels',
    },
    channels_with_param: {
      endpoint: 'teams/${team_id}/channels?isOpen=${is_open}',
    }
  }
}

const resp = fetchJSON({
  config: api_config,
  resource: 'channels_with_param',
  params: {
    team_id: 4,
    is_open: true
  }
})

const resp = fetchJSON(
  {
    url: url,
    method: 'GET',
    success_deserializer: successJsonApiDerserializer,
    error_deserializer: errorJsonApiDerserializer,
  }
)

resp.ok // => boolean
resp.data // => returns the response from fetch passed to successJsonApiDerserializer(response.json())
resp.error // => returns the errors from anything that does not return resp.ok or other errors from fetch passed to errorJsonApiDerserializer
