Users who want more advanced usage, or want to run Lighthouse in an automated fashion should use the Node CLI. The Node CLI provides the most flexibility in how Lighthouse runs can be configured and reported. Run it: follow the extension quick-start guide. Installation: install the extension from the Chrome Web Store. The Chrome extension was available prior to Lighthouse being available in Chrome Developer Tools, and offers similar functionality. Run it: open Chrome DevTools, select the Lighthouse panel, and hit "Generate report". Lighthouse is integrated directly into the Chrome DevTools, under the "Lighthouse" panel. How do I author custom audits to extend Lighthouse?.How do I get localized Lighthouse results?.How does Lighthouse use network throttling, and how can I make it better?.Lighthouse Integrations in non-Web Perf services.Lighthouse Integrations in Web Perf services.This approach is demonstrated in the following sample code.Lighthouse analyzes web apps and web pages, collecting modern performance metrics and insights on developer best practices. That's why, to support authentication on multiple browsers web apps will have to set the SameSite value to None only on Chrome and leave the value empty on other browsers. Other browsers (see here for a complete list) follow the previous behavior of SameSite and won't include the cookies if SameSite=None is set. To overcome the authentication failures, web apps authenticating with the Microsoft identity platform can set the SameSite property to None for cookies that are used in cross-domain scenarios when running on the Chrome browser. If you don't update your web apps, this new behavior will result in authentication failures. There are other cookies dropped by Azure Active Directory (Azure AD) to hold the session. The cookies that need to be used in cross-site scenarios are cookies that hold the state and nonce values, that are also sent in the login request. Because this request is a cross-domain request (from to your domain - for instance ), cookies that were set by your app now fall under the new rules in Chrome. When web apps authenticate with the Microsoft identity platform using the response mode "form_post", the login server responds to the application using an HTTP POST to send the tokens or auth code. These updates will soon be released in an upcoming version of the Chrome browser. Additionally, a value of None is introduced to remove restrictions on cookies being sent. This mitigation means cookies will be restricted on HTTP requests except GET made from other sites. Recent updates to the standards on SameSite propose protecting apps by making the default behavior of SameSite when no value is set to Lax. SameSite changes and impact on authentication An application would need to opt-in to the CSRF protection by setting Lax or Strict per their requirements. A value of Strict ensures that the cookie is sent in requests only within the same site.īy default, the SameSite value is NOT set in browsers and that's why there are no restrictions on cookies being sent in requests.It isn't sent in GET requests that are cross-domain. When SameSite is set to Lax, the cookie is sent in requests within the same site and in GET requests from other sites.SameSite is a property that can be set in HTTP cookies to prevent Cross Site Request Forgery(CSRF) attacks in web applications: ![]()
