How to use graphql-iso-date in makeExecutableSchema?

[stubailo]

Like this, just like you would use any other scalar type package: https://www.apollographql.com/docs/graphql-tools/scalars.html#Using-a-package

Let me know if that helps!

Thanks, the following code can also solve my requirement:

Date.prototype.toString = function() {
  return this.toISOString();
};

Do I still need to use graphql-iso-date?

[giautm]

@J-F-Liu : yes, because graphql-iso-date support parses Date from the formated string.

[stubailo]

Yep - you will get native Date objects in your resolver arguments with the custom scalar, so it is definitely nice!

Would someone like to send a PR to the docs here to add a date example? https://www.apollographql.com/docs/graphql-tools/scalars.html

You want to update https://www.apollographql.com/docs/graphql-tools/scalars.html#Date-as-a-scalar to use graphql-iso-date? Because otherwise, there is already an example there...

[stubailo]

Oh, right I forgot there's a date example. Hmmmmmm.... is graphql-iso-date better than the example listed on that page?

[kbrandwijk]

Well, for me it is the standard go-to package for using dates, so it might be better than the DIY date example. On the other hand, there is already a JSON example that uses a standard package, so maybe it would be enough to just mention it there?

[stubailo]

Yeah for sure. Might be just a small addon with a code snippet. I think we want a DIY example, maybe we can do one for Mongo ObjectIDs or something.
