How to run a nodeJS script with depencencies in Functions ?

I want to run a simple nodeJS script as a function in DO Functions. But the nodeJS requires one or more dependencies which need to be stored in node_modules. How do we run a nodeJS script that way ? I mean, we would need to upload a package.json and run npm i right before we can execute that script as a function in DO ?

Hi there,

You can still have your dependencies defined in a package.json file as normal. The platform will detect the file and will install those dependencies as normal.

You don’t have to commit the node_modules directory.

Here is an example of a Node App with a package.json file:

https://github.com/digitalocean/sample-functions-nodejs-qrcode/blob/main/packages/qr/qr/package.json

https://github.com/digitalocean/sample-functions-nodejs-qrcode

The README.md file contains the instructions on how to deploy that sample Node function.

Let me know if you have any questions!

Best,

Bobby
