walt-link

walt-link

Linker for walt WebAssembly Programs.

About

Wraps .walt file with a JavaScript module, with all the dependencies linked.

Intented to be used in a node environment. Not yet implemented in a loader.

Still under development, but the API wont change.

Notes

• Any import with a leading dot(.) will be linked into the final binary
• Anything without a leading dot(.) will be treated as an environment import and is left up to the user to implement.
• The top-level function returns a factory method which returns a function taking an import object. Every call to the method returns a brand new module
• importObj used in the factory method is shared accross all modules.
• Walt Dependencies are shared within a single WebAssembly module instance. Each import is a stand alone module linked by the linker. This is useful if you want shared module state across imports, similar to node modules.
