export-all json output format

[drortirosh]

in continuation of #248 ,
I'm still confused about the output of --export-all:

The current export format is:

{
  "5": [
    {
      "name": "goerli",
      "chainId": "5",
      "contracts": {}
    }
  ]
}

and I'm trying to understand the need for an array per chain.
The chain "name" is a unique key (both in hardhat.config file, and as a folder under deployments
so it seems the simpler format should be:

{
  "goerli": {
    "name": "goerli",
    "chainId": "5",
    "contracts": {}
  }
}

The only possible "downside" is that if you keep 2 configurations deployed on the same network (e.g. goerli-prod, goerli-stage), they would appear as separate "top-level" entries in the all-networks file, instead of lumped together as array elements under "chainId":5

name is not the chain name but the network name, and in hardhat you can have multiple network name for the same chain.

I use a lot for having different deployment on testnet or even keep tracking of multiple version on one chain

The rationale for the key being the chainId, is that for frontend that let you chose a specific network per chain.

You read it from the current chain and see you have an array with length > 1
