vulkan_bun_helloworld v0.1.0

vulkan_bun_helloworld

vulkan_bun_helloworld is a Vulkan helloworld program that runs in Bun.

vulkan_bun_helloworld uses:

• vulkan4bun
• glfw4bun

Which are bindings generated with makebindingsforbun.

The code is a simplification of the Vulkan tutorial.

Running

bun install bun helloworld.ts

If everything works you will see a colored static triangle, FPS and logs will be shown in the terminal:

Dependencies

vulkan4bun and glfw4bun are pure javascript libraries that use Bun FFI to dynamically load necessary Vulkan and GLFW symbols. Therefore, the only requirements are:

• Bun
• vulkan4bun and glfw4bun
• Vulkan loader (vulkan.so.1) in the expected path (/usr/lib/x86_64-linux-gnu/libvulkan.so.1)
• A Vulkan-enabling GPU driver

Limitations

makebindingsforbun is experimental, making generated bindings experimental too. Only Linux and the AMD64 arch are supported. Ergonomics could be improved if makebindingsforbun generated typescript definitions.

Why

Apart from because it's fun, Javascript under Bun is probably the fastest runtime for a scripting language. Bun also promises a very low cost on making FFI calls.

Additionally, GPU intensive programs can easily be bottlenecked in the GPU, reducing the real cost of using slower languages than C/C++/Rust.
