A HTTP client adaptor that wraps axios’s get, post, patch and delete methods, adding JWT token to all requests if a token is found.
This adaptor hook exists for the following reasons:
- it acts as an adaptor to
axios, so that in the future, I could replace
axioswithout touching any other code
- it adds base URL, JWT and default headers to HTTP calls for conveniences
- the hook returns a set of methods for making HTTP calls
- it prepends base URL
- it adds JWT token to headers if a token is found
- it adds default headers
- it accepts custom headers and overrides default headers
- it accepts custom options and passes them to HTTP requests
axiosso that tests don't make actual HTTP calls
- JSDOM implements
localstorage, and there is no need to mock it.
@testing-library/react-hooks, which wraps the hook in a component and return a
currentproperty set to whatever the hook returns.
setupalso mock the return of
axios.getmethod and returns the mocked axios object for assertions.
- included tests only test
get. Other tests are similar, so they are left out in this blog post for simplicity.
