Spin 3.0 – open-source tooling for building and running WASM apps
The latest major release of Spin is here - with new features like Component Dependencies, Selective Deployments, Otel Integration, and Spin Factors.
Spin 3.0 introduces a workflow for this type of development in the hopes of making it seamless to do things like write a library for some compute intensive task in Rust and use that as a dependency in a JavaScript application. Now, I think this particular feature is wild and could go on about it for at least a thesis, but there are even more Spin 3.0 topics to discuss so feel free to dig deeper in the component dependencies documentation and in the demo later on. These embeddings have slightly different environments and needs so we outgrew this concept of a “host component” and built an entirely new abstraction called Spin Factors based on these learnings.
