The SDK ships with three built-in token store implementations: Browser cookie store, Express cookie store and memory store. However, in some cases you may need to write your own cookie store, for example, if you want to save the cookie in some other location, such as LocalStorage.
The Token store interface has three methods. Any token store implementation must implement all of them:
setToken(Object) : null | Promise(null)
Stores the new token. Returns either null or a Promise.
getToken() : Object | Promise(Object)
Reads the token from the store. Returns either a token or a Promise holding the token as a value.
removeToken : null | Promise(null)
Removes the stored token. Returns either null or a Promise.
See the built-in token store implementations.
