how to use Protractor on non angularjs website?

Another approach is to set browser.ignoreSynchronization = true before browser.get(...). Protractor wouldn't wait for Angular loaded and you could use usual element(...) syntax.

browser.ignoreSynchronization = true;browser.get('http://localhost:8000/login.html');element(by.id('username')).sendKeys('Jane');element(by.id('password')).sendKeys('1234');element(by.id('clickme')).click();

If your test needs to interact with a non-angular page, access the webdriver instance directly with browser.driver.

Example from Protractor docs

browser.driver.get('http://localhost:8000/login.html');browser.driver.findElement(by.id('username')).sendKeys('Jane');browser.driver.findElement(by.id('password')).sendKeys('1234');browser.driver.findElement(by.id('clickme')).click();

waitForAngular should now be used instead of the deprecated ignoreSynchronization property.

The following waitForAngular guidance is taken from the Protractor docs for timeouts:

How to disable waiting for Angular

If you need to navigate to a page which does not use Angular, you can turn off waiting for Angular by setting `browser.waitForAngularEnabled(false). For example:

browser.waitForAngularEnabled(false);browser.get('/non-angular-login-page.html');element(by.id('username')).sendKeys('Jane');element(by.id('password')).sendKeys('1234');element(by.id('clickme')).click();browser.waitForAngularEnabled(true);browser.get('/page-containing-angular.html');
