fetch-with-token
A simple wrapper around fetch that manages getting a token (typically oauth2 token or other refresh-able token) and updating it atomically when it expires or stops working.
You just need to write the code to get a new token and the code to analyze whether a retry is required.
import { createFetchFunction } from '@sesamecare-oss/fetch-with-token';
const partnerFetch = createFetchFunction({
async getToken() {
const body = await fetch('https://auth.partner.com?clientId=foo&secret=bar').then((r) => r.json());
return {
value: body.access_token,
expiration: new Date(Date.now() + body.expires_in),
};
},
});
// This call will go out with an authorization header
const response = await partnerFetch('https://partner.com');
