How to check if current connect is still valid or expired?

Hi,

I’m using JSforce Node.js package to interact with salesforce?

Is there anyway to check if current connected session is still valid or expired?

        var connection = new jsforce.Connection({
            loginUrl : LOGINURL
        });
        connection.login(USERNAME, PASSWORD + TOKEN, (err: any, res: any) => {
                if (err) {
                    console.log('Connection Completed With Error: ',  err);
                }
                console.log('Connection Token: ' + connection.accessToken);
                console.log('Connection instanceUrl: ' + connection.instanceUrl);
            });
        });

@johnoliv - that is surprising, but makes sense.

even without the issue you are having, logging in with username and password should be avoided if possible.

But if that is the best way for your use-case, you should still be able to use oauth2 using the username+password flow as documented here: https://help.salesforce.com/s/articleView?id=sf.remoteaccess_oauth_username_password_flow.htm&type=5 which should work with identity and can use the native token refresh flow while still using username and password.

Note: I am not 100% sure if jsforce supports this login flow natively, but you can make the request yourself to get the token, then initialize jsforce with the oauth2 data. I have a vague memory that I tried it once and jsforce did not work.

You need to create a connected app in your production org or a dev org (any org that does not get deleted)

new jsforce.Connection({
  oauth2: new jsforce.OAuth2({
    loginUrl: 'instance-url',
    clientId: 'client id from connected app',
    redirectUri: 'redirect url from connected app, does not matter what it is since not used in this flow but must be configured',
  }),
  instanceUrl: 'instance-url',
  accessToken: 'obtained from auth flow',
  refreshToken: 'obtained from auth flow',
  maxRequest: 5,
  version: '55.0', // best to set this otherwise default to really old version
});

AFAIK the only way to know if a connection is valid or not is to try out an API call, at which time the token might be refreshed automatically, if possible, or will fail.

const conn = new jsforce.conn({loginUrl: LOGINURL});
await conn.login(USERNAME, `${PASSWORD}${TOKEN}`);

console.log('Connection Token: ' + connection.accessToken);
console.log('Connection instanceUrl: ' + connection.instanceUrl);

// then later on, run something like this
try {
  const identity = await conn.identity();
  // VALID!
} catch(ex) {
  // NOT VALID!
}
