Using Xojo’s URLConnection to communicate with web services is pretty straightforward. But testing the actual REST API calls can get tricky. To make it easier to test and experiment with REST API calls, Paul created a app in Xojo for doing just this. He called it RESTy in its original format back in 2015.

Comments closedThere are situations where the included controls and widgets aren’t enough. Maybe the specs of the project require the use of one or more of specific JavaScript libraries, or you just need some code to be executed in the browser. The Web SDK can help, giving you the opportunity to build anything. In 2022r4 we are adding more examples, to help you start building your custom controls.

Does anyone else feel like 2022 is the first year in many years where we have gotten back together, in-person, for big events, small get-togethers, travel and even the daily office grind? Whether that is the right thing to have done or not, it seems that is what many of us did in 2022. Though we all tried new things to stay connected over the past few years (Zoom-fatigue anyone?), there’s nothing like seeing an old friend after years apart.
Comments closedWe’re happy to add Sydney, Australia to the worldwide locations of Xojo Cloud servers. That makes nine cities that you can host your Xojo Cloud web apps in. Offering worldwide coverage for Xojo Cloud makes it easier to get your Xojo web applications close to the users that are using them, improving the speed and overall experience for your users.
