I’ve just finished and published my first npm package. My intention is to be able to require it from Observable. I’m pretty new to the whole package business and find it hard to get my head round the whole thing. Unsurprisingly, my package is not yet set up properly to be required from Observable, but it does run correctly in Node.
Could anyone point me towards a good tutorial on this, or a template package that I can crib my package.json from, given what I’m trying to achieve? I find the whole build/transpile bit confusing, so I’m not sure I’m anywhere close with my configuration, despite having read quite a few tutorials.
I’ve updated my package.json. I’m building using Parcel but I think I had it incorrectly configured, in that my option to build a module was being ignored. I believe I’ve corrected this.
However, I still have no joy importing: unpkg shows that there is a dist/module.js file though.
That’s to be expected, I think. Afaik unpkg isn’t a bundler, but will only rewrite import paths. Your d3 import would have to be bundled with your package.
esm.sh works though:
model = (await import('https://esm.sh/micro-table')).model
(You may want to make .model your default export.)
Interestingly, importing via skypack
import('https://cdn.skypack.dev/micro-table')
fails with the error
Error: [Package Error] "d3@v7.7.0" could not be built. (Imported by "micro-table").
But it appears that they have some server troubles - their search is broken as well.
Anyway, recommending your users to import via a 3rd party service like esm.sh is perfectly fine, in my opinion. Many popular packages do it, and it will let you focus your time and resources on more important things.
