Question

Functions and library support (sharp) error

Posted on November 11, 2023
DigitalOcean Functions DigitalOcean App Platform
Asked by Joe Hannouch

I’ve been migrating my services from GCP to Digital Ocean App Platform.

I had a Cloud Function in GCP that I’ve been using as a background job that generates images and merges layers which relies on the sharp library, the function has 4GB of allocated memory (in GCP).

I created my namespace and deployed the QR code example to test things and all is working. (deployed using doctl, amazing tool)

I allocated the max 1024MB for this function.

However, as soon as I imported my dependencies (no logic code yet just imports require calls) I got an error with sharp:

Something went wrong installing the “sharp” module

Cannot find module ‘…/build/Release/sharp-linux-x64.node’

Any input is appreciated

Hi!

I just tried to use Sharp for my use and I’ve made it work by using exact engine type.

For it, make sure you use:

Node.js version 18 (“runtime: nodejs:18”)
Installed sharp dependency with the last version (“^0.33” at this moment)
Added “postinstall” script with command “npm install --os=linux --cpu=x64” to the package.json file of a package action, because DigitalOcean Function runs on linux64.
