Your Java expertise doesn't stop at the server. Codename One brings Spring Data-style repositories to native clients and backends. Wayline's findFirstByDriverAndStateIn(...) finds an active ride; the build generates the implementation. #Java #Native codenameone.com/blog/reposit…

A Java IDE in your browser that is "not a cloud IDE": editing, compiling and the app preview all run in the page, and your files stay in browser storage. Very early and experimental. Download the ZIP to continue on your desktop. codenameone.com/blog/not-a-c…

An admin table doesn't need its own frontend application. Our Java catalog serves pages and htmx fragments from compiled Thymeleaf-style templates. Add a product; update the table. #Java #htmx codenameone.com/blog/compile…

Your CI container doesn't need a pretend monitor to build a Java app's theme. Codename One's CSS compiler now runs headlessly: mvn -Djava.awt.headless=true cn1:css. Delete the framebuffer setup. #Java #CSS codenameone.com/blog/headles…

Break the demo. Replace 3 with "three" in our Java record example and the Playground catches the type error before it runs. Fix it, click the button, and watch your compiled listener update the UI. #Java codenameone.com/blog/playgro…

Your Android app can outgrow Android. Import classic Activities and XML layouts into Codename One, then ship to iOS, desktop and web from one codebase. Replace screens on your schedule. #Java #Android codenameone.com/blog/android…

A familiar iOS feel shouldn't mean giving up control of your UI. UIKit above, Codename One below: same gestures, iOS simulator. Can you spot the differences? #Java #iOS codenameone.com/blog/ios27-g…

A playground is less useful if broken Java looks runnable. Codename One checks records and lambdas before updating the preview. Try an intentional type error, then fix it. #Java #DeveloperTools codenameone.com/blog/playgro…

Your browser app's View command shouldn't be a treasure hunt. Codename One can expose Java commands in an HTML menu bar. Try it with a screen your users actually navigate. #Java #WebDevelopment codenameone.com/blog/browser…

Your users skip releases; your database upgrade can't skip their data. Codename One brings #Flyway-style SQL migrations to apps and backends. Test the upgrade from an old database before you ship. #Java codenameone.com/blog/databas…

The Codename One Playground compiles Java in your browser. Paste the record-and-lambda example, click its button, then break a constructor argument to inspect the compiler error. codenameone.com/blog/playgro…

In a world where app UIs are increasingly uniform, Uber stood out by maintaining different transitions for iOS and Android. This subtle distinction emphasizes that feel is just as crucial as look. buff.ly/43TQeVR
