Shopify describes using WebAssembly (Wasm) outside the browser to run untrusted Partner code on its own infrastructure, reducing partners’ need to operate scalable web services and avoiding network latency for time-sensitive customizations. Wasm provides a sandboxed, stack-based environment with explicit host imports, protected call stacks, and runtime type checking, while targeting near-native performance and multiple source languages. Shopify wraps Fastly’s open-source Lucet runtime and compiler in a Rust web service called the Wasm Engine, which manages module I/O and storage and applies results during runtime processes such as web requests. In a test executing 100,000 modules per minute for roughly five minutes, Lucet execution hovered around 100 μs and total p99 execution time was about 4 ms. Shopify selected AssemblyScript, with TypeScript-like syntax, for first-class developer support and is extending its tooling, SDKs, monitoring, and language support.
