Interceptor

balena.interceptors.Interceptor : object

An interceptor implements some set of the four interception hook callbacks. To continue processing, each function should return a value or a promise that successfully resolves to a value.

To halt processing, each function should throw an error or return a promise that rejects with an error.

Kind: static typedef of interceptors Properties

Name	Type	Description
[request]	function	Callback invoked before requests are made. Called with the request options, should return (or resolve to) new request options, or throw/reject.
[response]	function	Callback invoked before responses are returned. Called with the response, should return (or resolve to) a new response, or throw/reject.
[requestError]	function	Callback invoked if an error happens before a request. Called with the error itself, caused by a preceeding request interceptor rejecting/throwing an error for the request, or a failing in preflight token validation. Should return (or resolve to) new request options, or throw/reject.
[responseError]	function	Callback invoked if an error happens in the response. Called with the error itself, caused by a preceeding response interceptor rejecting/throwing an error for the request, a network error, or an error response from the server. Should return (or resolve to) a new response, or throw/reject.
