Relay: Type generation for custom scallars

[steida]

Something like this:

backingTypeMap: {
  EmailAddress: 'string',
  DateTime: 'string',
  Max1024Chars: 'string',
  Max140Chars: 'string',
  URL: 'string',
},

It would be awesome.

I currently solve this by copying RelayCompilerBin and RelayCopilerMain into the project and replacing empty customScalars: {} with this.

        customScalars: {
          Date: 'String',
          DateTime: 'String',
        }

AFAIK guys discuss config file which should solve this problem.

I do the same thing, replace in the generated compiler bin and then check that into VCS. Not ideal, a config file would be very nice.

[sibelius]

Right now you can use patch-package to make this easier

The right solution is a relay.config.js

This seems a duplicate of #2162, for which there’s a PR at #2745.
