Extensible WASM Applications with Go
Go 1.24 enhances WebAssembly capabilities with function export and reactor mode
WebAssembly (Wasm) is a binary instruction format that was initially created for web browsers, providing the execution of high-performance, low-level code at speeds approaching native performance. Furthermore, building as a reactor ensures that the exported functions can be called multiple times without requiring reinitialization, making it suitable for long-running applications or services. The addition of the ability to build a WASI reactor and export Go functions to Wasm in Go 1.24 represent a significant step forward for Go’s WebAssembly capabilities.
