Show HN: Compile Erlang to WASM and run as HTTP/incoming-handler
The "erwasm-http" GitHub repository demonstrates compiling Erlang to WebAssembly for HTTP handling. Users need specific tools and dependencies to set up and run the server, with location reporting concerns noted.

The GitHub repository "erwasm-http" is a proof of concept for compiling Erlang into WebAssembly (Wasm) and executing it as an HTTP handler using the WASI runtime. The project aims to implement the actor model of Erlang within the WebAssembly environment, necessitating a WASI runtime that supports the typed continuation proposal. To set up the project, users must install specific forks of `wasm-tools` and `wasmtime` from wasmfx, along with dependencies such as the Erlang compiler (`erlc`), Python for compiling Erlang into a textual BEAM representation, and `watcat` for bundling WAT files. To run the server, users can execute the command `make run` and then make a GET request to port 8080 to receive a short text response. It is important to note that the software may report the user's location to СБУ if a Russian keyboard is detected on a Windows system, and the author disclaims responsibility under the "це не ми" doctrine. For additional information or assistance regarding the project, users are encouraged to reach out.

Dynamic Translation of Smalltalk to WebAssembly
The article explores Smalltalk code translation to WebAssembly (WASM) within the Catalyst project. It details levels of Smalltalk, JavaScript, and WASM, focusing on direct Smalltalk to WASM optimization. A new translator, WATCompiledMethodTranslator, aids in this process, exemplified by a Smalltalk expression conversion. Creation of a WASM module for Smalltalk methods is explained, highlighting performance advantages and potential future comparisons with dynamic JS translations. Collaboration in the Smalltalk community is encouraged for further advancement.
