README.md

Trying to reproduce a crash in the libvips build bundled with Tropy:

$ node -v
$ SHARP_IGNORE_GLOBAL_LIBVIPS=true npm install
$ ls node_modules/sharp/vendor/8.14.2/linux-x64/THIRD-PARTY-NOTICES.json

This is to install the sharp and libvips binary.

Then you can run the script like this:

$ npx electron . [DIRECTORY]

This will process all JPG/PNG files in [DIRECTORY]. The script loads all the files, resizes, and converts them to WebP. All this happens in memory only; nothing is saved to disk.

index.js

const { app } = require('electron')
const { readdir } = require('node:fs/promises')
const { extname, join } = require('node:path')
const { argv, cwd } = require('node:process')
const sharp = require('sharp')

let accept = ['.jpg', '.png']
let output = []

let wd = argv[2] || cwd()
console.log(`using directory ${wd}`)

;(async function () {
  for (let file of await readdir(wd)) {
    if (accept.includes(extname(file).toLowerCase())) {
      output.push(
        sharp(join(wd, file)).resize(256).webp().toBuffer()
      )
    }
  }

  console.log(`processing ${output.length} image(s)...`)
  await Promise.all(output)
  console.log('done')
  app.quit()
})()
