Spin is a framework for building and running event-driven microservice applications with WebAssembly (Wasm) components.
WebAssembly
WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable compilation target for programming languages, enabling deployment on the web for client and server applications.

A practical guide to WebAssembly memory | radu's blog
Memory in WebAssembly is one of the topics that creates confusion for newcomers, particularly for those with experience in languages with memory management features like garbage collection, such as JavaScript, Go, or Java. In this article we explore using memory in WebAssembly in various scenarios - passing JavaScript arrays to Rust and AssemblyScript modules, checking for some basic memory leaks using Valgrind, or exchanging strings between runtimes and modules using Wasmtime.
Spindles
Spindle workflows allow you to write CI/CD pipelines in a simple format. They’re located in the .tangled/workflows directory at the root of your repository, and are defined using YAML.
