Apollo Client Transformers

This package is useful for when you have scalars, but you receive them serialized on the client and you don't really want to do the deserialisation in your view layer.

Install

npm i -S apollo-client-transformers

Usage

import { createTransformerLink } from 'apollo-client-transformers';

const DateTransformer = {
  parseValue(time) {
    return new Date(time);
  },
};

const transformers = {
  User: {
    createdAt: DateTransformer,
  },
};

const transformerLink = createTransformerLink(transformers);

// You can now concatenate it with your http link before creating the client like so:
const enhancedHttpLink = transformerLink.concat(httpLink);
