alpine-apk
Use this package to read the contents of Alpine's package repository.
Usage:
import AlpineApk from 'alpine-apk'
/* by default:
version is 'latest-stable'. See versions here: http://dl-cdn.alpinelinux.org/alpine/
architecture is 'x86_64'
repos are ['main', 'community']
*/
const alpineApk = new AlpineApk();
await alpineApk.update(version, architecture, repos);
const nodeJs = alpineApk.get('nodejs');
/* nodeJs.version = '18.16.1-r0'
nodeJs.deps = [
'ca-certificates',
'/bin/sh',
'so:libbrotlidec.so.1',
'so:libbrotlienc.so.1',
'so:libc.musl-x86_64.so.1',

*/Why use this?
I wanted to rebuild my docker images when nodejs and/or nodejs's dependencies updated on alpine. This allows me to do that:
import AlpineApk from 'alpine-apk'
const alpineApk = new AlpineApk();
await alpineApk.update();
const current = alpineApk.getDependencyTree('nodejs');
const previous = /* load the previous value somehow */
if (current !== previous) {
// nodejs, or one of the dependencies of nodejs, has changed.
// rebuild the image!
}
