You can use the [BrowserSession integration](/platforms/javascript/configuration/integrations/browsersession/) in browser environments and the [Http integration](/platforms/javascript/guides/node/configuration/integrations/http/) (via the `trackIncomingRequestsAsSessions` option) in Node.js runtime.
