Adding DI to HttpBackend

[progital]

We want to mock HttpRequest for our tests. So lets add an optional constructor argument - "creator" function. If it's defined then createXHR method returns its result.

I think we made the HTTP client injectable since this Issue was opened, but I'm not 100% sure. Needs verification.

The cost of mocking requests for testing purposes may be higher than doing integration tests against a real node.

yes the http cient is now injectable:

is the HTTP client in Taquito injectable ?

Yes, the HTTP client in Taquito is injectable. Taquito is a TypeScript library for building ÐApps on the Tezos blockchain, and it allows you to customize and inject your own HTTP client. This feature is useful for developers who want to use a specific HTTP client or implement custom logic for handling network requests.

To inject your own HTTP client, you need to implement the RpcClient interface provided by Taquito. This interface defines the methods that your custom HTTP client should have. Once you have implemented the RpcClient interface, you can pass your custom HTTP client instance to the RpcProvider or TezosToolkit constructor.

Here's an example of how to inject a custom HTTP client:

import { TezosToolkit, RpcClient, RpcProvider } from '@taquito/taquito';

class MyCustomHttpClient implements RpcClient {
  // Implement required methods from RpcClient interface
  // ...
}

const customHttpClient = new MyCustomHttpClient();
const rpcProvider = new RpcProvider(customHttpClient);
const tezos = new TezosToolkit(rpcProvider);

By injecting your custom HTTP client, you can control how Taquito interacts with the Tezos RPC and customize the behavior as per your requirements.
