Hi, Have some problems with using nakama js client, what should I’d when the token will expired soon? client.authenticateEmail return session didn’t bring refresh\_token like account/authenticate/device api, if it will return refresh\_token how could I use refresh\_token to get a renew token?

```auto
const client = new Client("defaultkey", "127.0.0.1", "7350");
const session = await client.authenticateEmail(email, password, false, name);

```

Nakama Server : 3.3.0  
nakama-js : 2.1.5

Thanks for helping!

You can use this method.

```auto
async checkSessionAndAuthenticate() => { 
        let nakamaAuthToken = localStorage.getItem("nakamaAuthToken");
        if (nakamaAuthToken && nakamaAuthToken != "") {
            this.logger.log("Session Found");

            this.session = Session.restore(nakamaAuthToken);
            let currentTimeInSec = new Date() / 1000;
    
            if (!this.session.isexpired(currentTimeInSec)) {
                // Session valid so restore it
                this.session = this.session;
                this.logger.log("Session Restored");
                
            } else {
                this.logger.warn("Session Expired");
                
                await this.createSession()
            }
        } else {
            await this.createSession()
        }

        if(this.uselogs) {
            this.logger.success("Authenticated Session");
        }
    }checkSessionAndAuthenticate = async () => { 
        let nakamaAuthToken = localStorage.getItem("nakamaAuthToken");
        if (nakamaAuthToken && nakamaAuthToken != "") {
            this.logger.log("Session Found");

            this.session = Session.restore(nakamaAuthToken);
            let currentTimeInSec = new Date() / 1000;
    
            if (!this.session.isexpired(currentTimeInSec)) {
                // Session valid so restore it
                this.session = this.session;
                this.logger.log("Session Restored");
                
            } else {
                this.logger.warn("Session Expired");
                
                await this.createSession()
            }
        } else {
            await this.createSession()
        }

        if(this.uselogs) {
            this.logger.success("Authenticated Session");
        }
    }

```

you can get more info in this repo, is a wrapper for Playcanvas but the code is the same for any engine: [GitHub - zentyk/pc.nakama: A wrapper for heroiclabs/nakama JS client for use in playcanvas.](https://github.com/zentyk/pc.nakama)

```auto
import {Client, Session} from "@heroiclabs/nakama-js"

    }

    joinToMatch = async (id) => {

        this.oponents = this.match.presences.filter((presence) => {
            // Remove your own user from list.
            return presence.user_id != this.match.self.user_id;

        this.oponents.forEach((opponent) => {
