Twitter is changing Twitter.com to be more like mobile app

pic.twitter.com/8y4TMzqBGa— Twitter (@Twitter) July 15, 2019Built on a new back end that allows for modular delivery of features and code, the new site unifies the mobile and desktop experience for Web users—while carrying over the customizations that are available to mobile app users.Tabs and a side navigation bar now provide easy access to bookmarks, lists, and the user's profile. "We also felt it was the right moment to do something different: to set both our developers and our users up for Twitter's future."From a back-end perspective, the new website only sends down the code components in use at any time to the Web client—so a phone user would not see the sidebar visible on the desktop site until they tried to access its functionality, reducing the code's footprint on the device.As a result of the modular approach, Croom and Baker said, "we can now cater each component (or piece of the site) to each specific user." That includes tailoring the Web experience to reduce the amount of data required to deal with metered or slow Internet connections as well as deployment of code for user interface elements such as keyboard shortcuts."Keyboard shortcuts will rarely be helpful for a touch-screen mobile user," Croom and Baker noted, "but for a tablet user with a keyboard, they could be just as handy as on a full-size desktop.
