Issue when using with express

[Loyz07]

Hello kriasoft,

First thanks for your job. Very helpful !

I try to use this package within an express server but i face an issue. When i try to display the original image all works fine but when i add a manipulation prefix (for instance w_50), the cache image is generated in the cache bucket but empty 😳.

If i use the createHandler directly in a cloud function all works very well !

Could you help ? Thanks.

Here a sample of my code

` const express = require('express'); const { createHandler } = require('image-resizing');

const app = express(); const port = 3000;

app.get( '/*', createHandler({ sourceBucket: 'gs:///assets', cacheBucket: 'gs:///cache', }) );

app.listen(port, () => { console.log(Example app listening at http://localhost:${port}); }); `

Most likely it means that ImageMagick is not installed on the machine where you run this code. Also note note that ImageMagick is one of the pre-installed native modules in Google Cloud Functions (GCF) environment. On MacOS you can install it via Brew:

$ brew update
$ brew install imagemagick

BTW, if you can create a PR with this info added to README.md that would be awesome!

Hello Kriasoft,

You're right, with ImageMagick installed all works well.

I prepared a branch to create the PR but i don't have the permission to push it on the repo so I don't know how to create a PR. Sorry for that.

I only added the small text: Note that ImageMagick must be installed for this package to work. It is one of the pre-installed native modules in Google Cloud Functions (GCF) environment. On MacOS you can install it via Brew:

brew update
brew install imagemagick

If you plan to deploy this package inside a Docker container, do not forget to install ImageMagick. For instance, when using node:alpine base image, add the line below in your Dockerfile.

RUN apk add --no-cache file imagemagick
