Learning notes and practises of WebAssembly.

Background

Solomon Hykes, the founder of Docker, has posted on Twiter:

WASI

The WASI (WebAssembly System Interface) is a modular system interface for WebAssembly.

• WASI Annoucementment

Runtime

To run the wasm modules out of browser, it requires a runtime to execution the .wasm or .wat as VM. The runtime typically supports both WASI APIs as well.

• wasmer

  The wasmer is proud of its performance.

• wasmtime

  It is a JIT-style runtime. It is now a project in Bytecode Alliance. WASI API is well supported: WASI tutorial

I suppose! wasmer doesn’t have much documentation on writing programs using the WASI API, while wasmtime has enough of a tutorial to get you started.

Debating about comparison on the runtimes

• A interesting thread discuss the wasmer vs. wasmtime from Developers: https://github.com/wasmerio/wasmer/issues/142
• Actually using WASM, examples with wasmer and wasmtime.

WASM-VDOM

Use wasm for comparing virtual DOM to optimize the performance:
