@aofl/api-request v3.14.1

@aofl/api-request

A module for making api calls easier. Key features include caching responses and request/response formatters.

Caching is implemented using @aofl/cache-manager and uses MemoryCache. @aofl/api-request caches the promises created by fetch api.

Request/response formatting refers to constructing a request payload and parsing the response payload. A formatter object should implement pack() and unpack() properties. pack() is to construct the request payload and unpack() is used to parse the response. Any number of formatters can be added to apiRequestInstance using the addFromatter() method. E.g. GetFormatter, PostFormatter, CorsFormatter, FileUploadFormatter, GoogleMapsFormatter, ....

  static unpack(response) {
    return response.json()
    .then((data) => {
      if (data.status !== 'success') {
        return Promise.reject(data);
      }
      return data;
    });
  }
}

const apiRequestInstance = new ApiRequest();
apiRequestInstance.addFormatter('post', PostFormatter);

})
.catch((jsonResponse) => {
