Creating a MSGraph Client with an already-existing accessToken

[tyteen4a03]

I am trying to access MSGraph based on an access token. All of the tutorials seem to gear towards also fetching the access token for me, which I don't need.

Are there any examples where I can just pass in an access token to get to a client?

I ended up doing this:

export const createAccessTokenClient = (accessToken: string): Client => {
    const authProvider = new (class implements AuthenticationProvider {
        async getAccessToken() {
            return accessToken;
        }
    })();

    return Client.initWithMiddleware({
        debugLogging: true,
        authProvider: authProvider,
    });
};

You did exactly the right thing! Providing your own authProvider is the right approach! I'll be closing it for now!

Can this be included in the documentation?

We have it as part of the repo docs: https://github.com/microsoftgraph/msgraph-sdk-javascript/blob/dev/docs/CustomAuthenticationProvider.md
