Make Node.js API

Is your feature request related to a problem? Please describe.

squoosh has CLI, so I think it is possible to implement Node.js API

Describe the solution you’d like

Adding Node.js API

Does other service/app have this feature?

For example - imagemin have CLI and Node.js API

Additional context

The Node.js API will allow squoosh to be used in other tools, for example I am developers https://github.com/webpack-contrib/image-minimizer-webpack-plugin and now we use imagemin for this, but setup is complex and unable on some platform because libraries for compression compiled on developer machine

@alexander-akait in the meanwhile, you can use exec or it’s asyc sister. Actually might be better to always run CLI this way (after adding commander or yargs) for a CLI if one uses the same pattern often.

const { exec } = require("child_process")

let file = './img/codepen.io-2021-02-15.png'
let rounds = 2
let bt = 1.1

exec(`squoosh-cli -s .r${rounds}bt${bt} --avif --max-optimizer-rounds ${rounds} --optimizer-butteraugli-target ${bt} -d out ${file}`,  (error, stdout, stderr) => {
	if (error) {
			console.log(`error: ${error.message}`);
			return;
	}
	if (stderr) {
			console.log(`stderr: ${stderr}`);
			return;
	}
	console.log(`🎆 success!
${stdout}`);
})

Yup, at some point I want to re-factor the CLI to have a proper separation between a libsquoosh and the cli
