Logging into Salient Data uses the GraphQL Resolver RootMutation createPost().

This resolver is a member of the mutation family.

GraphiQL Mutation

mutation {
  createPost(salient: {
    title: "{title}",
    content: "{salient-data}",
    summary: "{description}",
    bank: WELLSFARGO
  })
  { 
    _id
    title
  }
}

The resulting data is:

{
  "data": {
    "createPost": {
      "_id": "5a6896734dad9a3321ad0633",
      "title": "{title}"
    }
  }
}

The field bank is an enumeration of bank names predefined.

enum Banks {
  WELLSFARGO
  BANKOFAMERICA
  { ... }
  OTHER
}

Apollo Client Mutation

Apollo Client requires the mutation be formatted in the following method

{
  mutation: gql`
    mutation createPost($title: String!, $content: String!, $salient: String!, $bank: String!) {
      createPost(salient: {
        title: "$title}",
        content: "$salient",
        summary: "$summary",
        bank: $bank
      })
      { 
        _id
        title
      }
    }
  `,
  variables: {
    title: f.value.title,
    salient: JSON.stringify(f.value.content),
    summary: f.value.summary,
    bank: f.value.bank
  },
}

Because we are working with RESTful API's, all salient data, whether xml or JSON must be stringified before submitting.

Apollo Client has several dependencies , which includes the graphql-tag

In the client, the following code would be used.

import { Apollo } from 'apollo-angular';
import gql from 'graphql-tag';

class LogIn { ... }

constructor(
  private apollo: Apollo
) {}

const post = {
  mutation: gql`
    mutation createPost($title: String!, $content: String!, $salient: String!, $bank: String!) {
      createPost(salient: {
        title: "$title}",
        content: "$salient",
        summary: "$summary",
        bank: $bank
      })
      { 
        _id
        title
      }
    }
  `,
  variables: {
    title: f.value.title,
    salient: JSON.stringify(f.value.content),
    summary: f.value.summary,
    bank: f.value.bank
  },
};

this.apollo.mutate(post).subscribe(console.log);
