I’m not at a computer right now, so typing on my phone, but I think you want:

import { ethers } from 'ethers'

constructor(provider: ethers.Eip1193Proviser | ethers.JsonRpcProvider) {
    this.provider = provider instanceof ethers.JsonRpcProvider ? provider: new ethers.BrowserProvider(provider)
  }

Let me know if that works. :)

(moving to discussions)

Thanks @ricmoo , i think it will work , i'm still migrating other stuffs too , will test , soon

what about :

providers.BaseProvider

I should use Eip1193Provider , too ?

[ricmoo]

That is probably best replaced with ethers.AbstractProvider which implements the ethers.Provider interface. Depending on whether you care about the implementation or interface. :)

thanks a lot @ricmoo , sorry if i ask many questions .

what about the following:

import { providers } from 'ethers'


const { Provider, StaticJsonRpcProvider } = providers
type AbstractProvider = providers.AbstractProvider


const getProviderFromConfig = (urlOrProviderOrProviderFunction: string | AbstractProvider) => {
  if (Provider.isProvider(urlOrProviderOrProviderFunction)) {
    return urlOrProviderOrProviderFunction
  }
  if (typeof urlOrProviderOrProviderFunction === 'function') {
    return urlOrProviderOrProviderFunction()
  }
  return new StaticJsonRpcProvider(urlOrProviderOrProviderFunction)
}

StaticJsonRpcProvider and Provider , how to migrate them
