Custom Scalar

[jvbianchi]

How can I add some custom Scalar like Date, Time, JSON and Enum?

I tried to follow this tutorial, but I could not make it work with this framework.

There are two options in bootstrap you can use:

bootstrap({ 

     customResolvers: {
          /// ... your resolvers
     },
     customTypeDefs: `
          /// ... your type defs (scalars and others)
     `
});

I'm trying to use it like this:

import { GraphQLDate, GraphQLTime, GraphQLDateTime } from 'graphql-iso-date';

bootstrap({ 
       customTypeDefs: [GraphQLDate, GraphQLTime, GraphQLDateTime],
});

but I got this error:

GraphQLError: Syntax Error GraphQL request (37:1) Unexpected Name "Date"

36:
37: Date,Time,DateTime
    ^

Am I using it wrong? Is there a example? I didn't find any in the documentation.

No, sorry I copy/pasted that block, actually customTypeDefs accepts a string, e.g. `customTypeDefs: "GraphQLDate \r\n GraphQLTime \r\n GraphQLDateTime"

Finally I could make it work, final code:

bootstrap({
  customResolvers: {
    Date: GraphQLDate,
    Time: GraphQLTime,
    DateTime: GraphQLDateTime,
  },
})

Thanks to @jvbianchi , I got mine working. I also got https://github.com/taion/graphql-type-json work in the same way except I have to declare scalar JSON in graphql as well. Not sure why graphql-iso-date does not require that.
