A Java to JavaScript transpiler that leverages TypeScript to write web and mobile applications using Java tooling.
JSweet is a Java to JavaScript transpiler that converts Java source code into TypeScript and JavaScript, allowing developers to write web and mobile applications in Java. It solves the problem of bridging Java's strong typing and tooling with the dynamic JavaScript ecosystem, enabling type-safe web development using popular JavaScript libraries.
Java developers who want to build web or mobile applications without leaving the Java ecosystem, and teams looking to share code between Java backends and JavaScript frontends.
Developers choose JSweet because it provides full type safety, integrates with existing Java tooling, and offers access to a vast array of JavaScript libraries through typed APIs, reducing errors and improving productivity in web development.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Leverages Oracle's Java Compiler and Microsoft's TypeScript to generate fully type-checked JavaScript, catching errors at compile time and reducing runtime bugs.
Provides typed Java APIs for over 1000 JavaScript libraries through candies, enabling seamless integration with frameworks like Angular, React, and jQuery.
Facilitates sharing core Java code between server and client, supported by implementations like J4TS for JDK libraries, easing legacy migration.
Works with Java IDEs, Maven, and Gradle, offering familiar development environments and streamlined build processes for Java-centric teams.
Candies are generated from TypeScript definitions and may not keep pace with frequent JavaScript library releases, potentially delaying access to new features.
Requires installing multiple tools (Git, Node.js, Maven) and configuring plugins, adding initial overhead compared to native JavaScript toolchains.
Debugging transpiled code in browsers can be challenging, as mentioned with the debug mode feature, requiring additional steps to trace issues in generated JavaScript.
