We use Axios as our data fetching library on the frontend, so the backend responses will ultimately come to the front end as the value of the data field of Axios's response object, which :
{
// `data` is the response that was provided by the server
data: {}, // or [{}] for "many return" requests (e.g. Rails #index action)
// `status` is the HTTP status code from the server response
status: 200,
// `statusText` is the HTTP status message from the server response
// As of HTTP/2 status text is blank or unsupported.
// (HTTP/2 RFC: https://www.rfc-editor.org/rfc/rfc7540#section-8.1.2.4)
statusText: 'OK',
// `headers` the HTTP headers that the server responded with
// All header names are lower cased and can be accessed using the bracket notation.
// Example: `response.headers['content-type']`
headers: {},
// `config` is the config that was provided to `axios` for the request
config: {},
// `request` is the request that generated this response
// It is the last ClientRequest instance in node.js (in redirects)
// and an XMLHttpRequest instance in the browser
request: {}
}
