Dynamic import

Hi all,

First off, I would like to thank you for ObservableHQ, it has been a great resource over the past 4 years, and the engineering behind it is remarkable.

I’m at a bit of loss with an issue I have at the moment.

I have a piece of code that looks like so.

import {exportCSVData as exportCSVData1} 
with {h1 as galaxyHistoryId}
from "@stevenweaver/ngsqc-parser"

h1 is currently an ID that is passed into another notebook. What I would like is iterate over a list of IDs, and assign an array of resulting export variables.

For example

import {exportCSVData as exportCSVData2} 
with {h2 as galaxyHistoryId}
from "@stevenweaver/ngsqc-parser"

import {exportCSVData as exportCSVData3} 
with {h3 as galaxyHistoryId}
from "@stevenweaver/ngsqc-parser"

and so on, but programmatically. Is there any way to make this possible?

Best and thank you,
Steven

Thanks Steven!

Yes, it’s possible to do dynamic imports (see this prototype) but I don’t think I recommend it as it’s not really a supported feature. Instead I recommend refactoring the notebook you import as a function and avoiding import-with entirely. So you might say something like this:

import {exportCSVData} from "@stevenweaver/ngsqc-parser"

exportCSVData({galaxyHistoryId: h2})

exportCSVData({galaxyHistoryId: h3})

You’ll have to rewrite your other notebook to be more function-based rather than cell-based, but overall it’ll make it easier to reuse in the standard JavaScript way.

Thank you mbostock.

I was leaning towards that way, but I just wanted to make sure.

Best,
Steven
