Time to say goodbye to the singleton instance?

[vikiival]

The singleton instance, rewritten 3 times is with us since summer 2019.
It served well but when you want to have multiple tabs with different chains it's not suitable

What does it cause:

• Glitch on make offer in basilisk nft-gallery#3220
• JS error in basilisk collection creation interface: undefined variable nft-gallery#3312

Also it would be nice to leverage

HTTP instead of WS
Use WebWorkers?

First drafts

import { InstantApi as Api } from '../dist/index.mjs'

const url = 'ws://localhost:9944'

async function main() {
  try {
    const api = await new Api(url).getInstance()
    const ss58 = api.consts.system.ss58Prefix.toString()
    console.log('PREFIX', ss58)
  } catch (e) {
    console.log('ERRR', e.target._url)
  }
}

main()
