GraphQL-Prisma-Info-Include

From your resolver's info argument to prisma include

Install

npm install graphql-prisma-info-include

Usage

Requirements

You need to have a GraphQL server and a prisma client (v2 / @prisma/client / @prisma/cli)

In your resolver, the fourth argument usually called info has the information about what you are supposed to return.

Example

import {infoToInclude} from "graphql-prisma-info-include";
// or const {infoToInclude} = require('graphql-prisma-info-include');

const resolvers = {
  Mutation: {
    createUser(_root, { name, email }, ctx, info) {
      return ctx.prisma.user.create({
        data: {name, email},
        ...infoToInclude({type: 'root', rootInclude: true}, info)
      })
    }
  }
}

API

infoToInclude(params: InfoIncludeParams, info: GraphQLResolveInfo)

info parameter is the fourth argument given by GraphQL resolvers. It can accept the following fields:

interface InfoIncludeParams {
  key?: string | string[]
  type: 'root' | 'union' | 'key'
  rootInclude?: boolean,
  isSelect?: boolean,
}

root

Example:

# The definition
type Mutation {
    createUser(name: String) : User
}

# The call
mutation {
    createUser(name: "Joe") {name id}
}

import {infoToInclude} from "graphql-prisma-info-include";

const resolvers = {
  Mutation: {
    createUser(_root, {name}, ctx, info) {
      return ctx.prisma.user.create({data: {name}, ...infoToInclude({type: 'root', rootInclude: true}, info)});
    }
  }
}

key

Example:

# The definition
type Mutation {
    createUser(name: String) : User
}

type UserError {
    data: User
    errors: [Error]
}

# The call
mutation {
    createUser(name: "Joe") {data {name id}}
}

import {infoToInclude} from "graphql-prisma-info-include";

const resolvers = {
  Mutation: {
    createUser: async (_root, {name}, ctx, info) => {
      return {data: await ctx.prisma.user.create({
        data: {name},
        ...infoToInclude({type: "key", key: 'data', rootInclude: true}, info)})
      };
    }
  }
}

union

Example:

# The definition
union UserReturn = User | Error

type Mutation {
    createUser(name: String) : UserReturn
}


# The call
mutation {
    createUser(name: "Joe") {...on User {name id}}
}

import {infoToInclude} from "graphql-prisma-info-include";

const resolvers = {
  Mutation: {
    createUser(_root, {name}, ctx, info) {
      return ctx.prisma.user.create({
        data: {name},
        ...infoToInclude({type: "union", key: 'User', rootInclude: true}, info)
      });
    }
  }
}
