WebAssembly import / js-wasm bindings initialization #19

Closed adomasven closed 5 years ago

adomasven commented 5 years ago

The current wasm JS bindings use the new nodejs wasm import syntax. At the moment this is not available in most environments, including browsers, older nodejs versions and the XPCOM environment Zotero is currently running in.

Could you provide an alternative API to supply the wasm bytecode for use with the WebAssembly API to the binding JS module, so that the citeproc-rs embedding application can use whatever API is available for them to load it?

Fortunately wasm-pack can do that. Did you try wasm-pack build --target no-modules? If you can get away with ES Modules syntax for exports, then prefer --target web, but either would be fine.

There's an example at https://rustwasm.github.io/docs/wasm-bindgen/examples/without-a-bundler.html. I've had a look at the output of no-modules, and it is very ES5.

Be aware of the caveats of builds that don't use a bundler like Webpack, which might be relevant. https://rustwasm.github.io/docs/wasm-bindgen/reference/browser-support.html (Also, you could always just slap Webpack in your build pipeline, right? One day!)

Oh right, thanks. Would be great if you put more details about this in README.md.

Refer to the docs for on how to get the output you need, particularly --target.

I updated it right after you last checked in.

Ah, I was looking under https://github.com/cormacrelf/citeproc-rs/tree/master/crates/wasm
