Transform request body for json-schema

[jangot]

I try to set up mesh for getting data from a service. The service has specific interface. I have no way to change the interface.
The service uses only POST requests to get and update data. All parameters for every method should be passed as an array in a request body.

Example

const accountId = 1;
const filter = {active: true}

const body = [accountId, filter];

fetch('/get/users', { method: 'POST', body });

When I try to setup it in json-schema I need to use requestSample in handler.operations. But it takes just object and if I set an array there the handler takes just first argument and ignore other.

What do you think about an opportunity to transform body before request. It can be a path to file like additionalResolvers

operations:
  - type: Query
    field: account
    path: /AccountsResource/getUsersByFilter
    method: POST
    requestSample: ./json-samples/account-input.json
    responseSchema: ./json-schemas/account.json#/definitions/Account

    # this is new option
    bodyTransform: ./json-transforms/account

requestSample can be like this

{
     "accountId": 1,
    "filter": {
        "active": true
    }
}

And this is transform example

// account-input.json

module.exports = {
    transform: (body) => {
        const { accountId, filter } = body;

        return [accountId, filter];
    }
}

It should work fine.

I think you can provide the actual request schema and add a new field that redirects to this field within additionalResolvers

additionalResolvers do not work well, I created an issue.
Ok I think I can add this but I will need to write all fields in additionalResolvers and why I need use mesh if I write all resolvers manually?

And my be you have other way to pass array to request body?
