WebSockets integration

[travisapple]

First off, this project is fantastic, thank you!

Feature Request:

I'm trying to integrate this into a websockets project that has no form tag. The challenge comes in via websockets, the user solves the challenge and the result is sent out via websockets to a server that verifies it.

This code works:

const altcha = document.createElement('altcha-widget')
altcha.setAttribute('challengejson', JSON.stringify( challenge ))
altcha.setAttribute('auto', 'onload')
altcha.style.display = 'none'

const c = document.querySelector('#container')
c.append(altcha)

await import('altcha.min.js')

altcha.addEventListener('statechange', (ev) => {
	if (ev.detail.state == 'verified') {
		console.log('altcha done')
	}
})

but it's pretty clunky using the dom when I don't need to. Is it possible to have something like this:

const result = await altcha.solve(challenge)

or maybe with a callback?

altcha.solve(challenge, (result)=>{
console.log('altcha done')
})

Hi, for this purpose you can use the solveChallenge function from the altcha-lib package (https://github.com/altcha-org/altcha-lib?tab=readme-ov-file#solvechallengechallenge-salt-algorithm-max-start) which does not require DOM.

Hey thanks OVX.

The front end widget doesn't have that function. solveChallenge() is only available on the server.

The package altcha-lib works also in the browsers, you have to install it instead of the widget.
