JavaScript ecosystem interoperability

Components transpiled by Jco are ordinary ES modules, and components built with Jco can reuse a large part of the existing JavaScript ecosystem. This section covers the pieces that make that possible.

• jco-std: the standard library that gives components access to WASI through familiar JavaScript APIs.
• Node.js built-in compatibility: which node:* modules work inside a component, and how each one maps onto WASI.
• Express: running an Express application as a component.
