Release pyodide as an npm/node package

[dmondev]

Are there any plans for releasing pyodide as an npm package ?

Being python for the web/browser, it makes sense to provide an npm package so it can be used along with the rest of the web development ecosystem, that revolves around node/npm and affiliates.

It seems that for the standard distribution, all we need is package.json + the contents of the build folder and of course an account in npmjs to publish (seems like there's another pyodide account there, that I'm not sure is related to you).

[Update] - 2021-04-02

I published an initial version based on 0.17.0a1 to the following org/package.

https://www.npmjs.com/package/@pyodide/pyodide

And also an example for running locally using a simple webpack-dev-server:
https://github.com/pyodude/pyodide-webpack

Notes about this package

• This version includes the standard distribution minus scipy/dependencies plus plotly. As the plan for the core distribution changes (distribute only the minimal build), the npmjs package can easily reflect that.

• Had to remove scipy (and dependents), as the files are too big for github/npmjs. I think that for newer versions there shouldn't be the same issue.

• I used 0.17.0a1 instead of dev(master), because of Memory access out of bounds in Chrome #1384. I'm mainly interested in using pyodide with plotly right now.

About "@pyodide" in npmjs

I hope you forgive me for taking the huge liberty of publishing this under @pyodide/pyodide. The org name was available in npmjs, and I already saw a couple of pyodide packages in npmjs, so I didn't want you folks to "lose" the org, or have to go through the process of claiming it for you.

I'd be happy to give ownership to the npmjs project/org, just let me know. I can maintain it for the time being, as I'm using pyodide, and very interested in keeping the npmjs package up to date.

I think this is one of our top priorities for v0.18.0.

And @dmondev feedback on #14 (comment) and generally what we currently have in https://github.com/pyodide/pyodide/tree/main/src/js with respect to what you would expect to see in the npm package would be very welcome.

[hoodmane]

If I'm not mistaken @hoodmane you also have access to npmjs.com/package/pyodide, right?

Yes that is correct.

[dmondev]

Sorry, @rth , I was offline for a while. I just invited you to the pyodide org at npmjs. I'll transfer ownership to you as soon as you join.

[dmondev]

@rth , you're now owner of @pyodide/pyodide, I added @hoodmane as well. Please remove me from the organization, I don't need to be there :)

[rth]

Thanks a lot @dmondev !

Just want to say huge thanks to @dmondev @rrth @hoodmane! Packaging pyodide into an npm package will make it much more accessible.

@rth @hoodmane Thank you for all the work in releasing v0.18! Follow-up question. Is the current pyodide npm package only for node.js, not the browser? The example in https://www.npmjs.com/package/pyodide is for Node.js only and I was wondering if I can use it in React (Next.js) projects.

[hoodmane]

You can use it in the same way in browser (e.g., with rollup or some other bundler). In that case you should set indexURL equal to https://cdn.jsdelivr.net/pyodide/v0.18.0/full/.

I'll give it a try with next.js. Thank you!
