Test compatibility of CO2.js in with other js runtimes

[mrchrisadams]

One of the goals we had for CO2.js, and one of the reasons we invested a bunch of time in making it work as a hybrid library was to support a wide number of runtimes.

We currently support the nodejs runtime, and most modern browsers, but there are other runtimes that use javascript too.

Some examples below:

• Appscript - Google has some limited support for javascript in Google apps like Google Sheets. There are existing patterns and guides for using code from npm inside appscripts
• Bun should be compatible, and is an growing alternative to nodejs, that has a few nice features, like being fast to start, and having built in sqlite support
• Deno, Elsa are both both runtime for server-side javascript, and can create self-contained compiled binaries that remove the need to have a javascript runtime installed at all.
• Mongodb uses the same underlying javascript engine as Firefox, Spidermonkey. So, presumably these kinds of calcs could be executed in Mongodb itself, a little bit like how some folks like Crunchydata do Machine Learning inside Postgres . I'm very much out of my depth here though, and haven't used Mongodb in years, so I have no idea how complicated running your own js in Mongodb is.

Re: Deno - They are planning to have more seamless NPM & Node interoperability in the next couple of months. https://deno.com/blog/changes#compatibility-with-node-and-npm

Untested yet, but we should be good in Deno as of 1.28

This will be good to eventually have documented on the docs site, but we'll keep a rolling list here for now.

• [x] Deno
• [ ] Elsa
• [x] Bun
• [ ] Appscript
• [ ] Cloudflare Workers
