Question 1

How to integrate TeaVM with Gradle?

Accepted Answer

Use the TeaVM Gradle plugin by adding it to your build.gradle file; the README references Gradle tasks and the project site provides detailed configuration examples for compilation targets.

Question 2

TeaVM vs GWT for Java to JavaScript?

Accepted Answer

TeaVM focuses on clean licensing and outputs like WebAssembly, while GWT is more mature but GPL-licensed. TeaVM is better for license-sensitive projects, but GWT has broader ecosystem support.

Question 3

Does TeaVM support Java 17 features?

Accepted Answer

Support varies; TeaVM's class library may lag behind the latest Java versions. Check the class library compatibility report or project updates for specific feature availability.

Question 4

Can I use Spring Boot with TeaVM?

Accepted Answer

It's possible but limited; TeaVM might not support all Spring dependencies due to JVM-specific behavior, so test with simple modules and consult the documentation for known issues.

Question 5

How to debug TeaVM compiled code in the browser?

Accepted Answer

TeaVM can generate source maps to map JavaScript output back to original Java code; use browser developer tools to set breakpoints and inspect variables for easier debugging.

Question 6

What are the bundle size implications of TeaVM?

Accepted Answer

Compiled bundles can be larger than native JavaScript; optimize by enabling tree-shaking in build tools and using WebAssembly for performance-critical parts to reduce size.
