Use multiple API Augmentations in the same DApp

[peetzweg]

I was able to augment my API following the docs here and using the new input from this PR polkadot-js/docs#445.

However, I'm struggeling how to get it to work if I want to work with multiple chains in a single project. So I want to have apiChainA and apiChainB properly typed augmented. If I generate both into different folders and import them I get a mixture of both maybe even breaking the api?

• What is the current behavior and expected behavior?

Using polkadot-types-from-defs & polkadot-types-from-chain to generate type augmentations with metadata for ChainA and ChainB.

ChainA only has a Balances Pallet, ChainB only has a Identity pallet.

import "./interfaces/chainA/augment-api.ts"
import "./interfaces/chainA/augment-types.ts"

import "./interfaces/chainB/augment-api.ts"
import "./interfaces/chainB/augment-types.ts"


const apiChainA = new ApiPromise({provider:new WsProvider("wss://chainA")})
const apiChainB = new ApiPromise({provider:new WsProvider("wss://chainB")})

// apiChainA and apiChainB both would have `api.tx.balances` and `api.tx.identity`
