Custom parser for custom scalars

[zhammer]

Is there support for using custom parser for schema-defined scalars? Common use case would be parsing Date scalar fields defined in a schema to date objects.

Handling of special floating point values is another usecase

any news on this? Is this in the works still?

[aryzing]

@zhammer were you able to figure it out?

any workarounds?

Here's our workaround for parsing DateTime type (from graphql-scalars) to Date and back. It works for our use case, but is less than ideal.

I created a small plugin you can use with graphql-request to transform custom scalars: https://github.com/gastromatic/graphql-transform-scalars
I tried already different scenarios in our project and it works well (also for union and interface types). I will add some tests in the coming days. Feedback welcome : )

This will be solved by #672

Actually this was not solved by the PR. This issue is now being tracked for the TS Client here: #744
