This is a client library for interacting with the [draft store api](https://github.com/hmcts/draft-store)

To configure the draft store client you need to:

* Implement the ServiceAuthTokenFactory interface.  
```
export interface ServiceAuthTokenFactory {
     get (): Promise<ServiceAuthToken>
   }
```
   
* Sample implementation:
```
let token: ServiceAuthToken

export class ServiceAuthTokenFactoryImpl implements ServiceAuthTokenFactory{
  async get (): Promise<ServiceAuthToken> {
    if (token === undefined || token.hasExpired()) {
      token = await IdamClient.retrieveServiceToken()
    }
    return token
  }
}
```   
# API available with clients

* DraftStoreClientFactory is responsible for creating DraftStoreClients

* DraftMiddleware manages number of draft store client can be configured and is available if user is logged in
