Salesforce GraphQL Helper

Salesforce GraphQL API client for browsers and Node with functionality to dynamically, quickly and easily create Salesforce GraphQL queries.

Installation

Use the Node package manager npm to install Salesforce GraphQL Helper.

npm install salesforce-graphql-helper

Usage

Required:

• Set an environment variable called SALESFORCE_ACCESS_TOKEN that stores a valid Salesforce access token that will be used for authentication.
• Set an environment variable called SALESFORCE_API_URL that stores your Salesforce API URL (e,g. https://MyDomainName.my.salesforce.com/services/data/v55.0).

GraphQlHelper Class:

Dynamically, quickly and easily create and invoke Salesforce GraphQL queries without worrying about syntax.

RootSObject:

Query field values from root object.

import { GraphQlHelper, RootSObject } from "salesforce-graphql-helper";

(async function start() {
  const queryHelper = new GraphQlHelper(
    new RootSObject("Account").addField("Id").addField("Name")
  );
  const response = await queryHelper.query();
})();

Query field values from multiple root objects.

import { GraphQlHelper, RootSObject } from "salesforce-graphql-helper";

(async function start() {
  const queryHelper = new GraphQlHelper();
  const account = new RootSObject("Account")
    .addField("Id")
    .addField("Name")
    .addFilter({ Name: { like: "Test%" } });
  queryHelper.addRootObject(account);
  queryHelper.addRootObject(
    new RootSObject("Contact").addField("Id").addField("Name")
  );
  const response = await queryHelper.query();
})();

ParentSObject:

Query field values from root object as well as field values from parent objects.

import { GraphQlHelper, RootSObject, ParentSObject } from "salesforce-graphql-helper";

(async function start() {
  const queryHelper = new GraphQlHelper(
    new RootSObject("Contact")
      .addField("Id")
      .addField("Name")
      .addParentSObject(new ParentSObject("Account").addField("Name"))
  );
  const response = await queryHelper.query();
})();

ChildSObject:

Query field values from root object as well as field values from child objects. Child relationships may only be requested as direct descendants of the root object type. You can't query fields from a child relationship pertaining to a parent of the root object.

import { GraphQlHelper, RootSObject, ChildSObject } from "salesforce-graphql-helper";

(async function start() {
  const queryHelper = new GraphQlHelper(
    new RootSObject("Account")
      .addField("Id")
      .addField("Name")
      .addChildSObject(new ChildSObject("Contacts").addField("Name"))
  );
  const response = await queryHelper.query();
})();

Filtering:

Set the where argument and filter type value (see the Filtering section of the GraphQL docs).

import { GraphQlHelper, RootSObject } from "salesforce-graphql-helper";

(async function start() {
  const queryHelper = new GraphQlHelper(
    new RootSObject("Account")
      .addField("Id")
      .addField("Name")
      .addFilter({ Name: { like: "Test%" } })
  );
  const response = await queryHelper.query();
})();

Ordering:

Set the orderBy argument and OrderBy type value (see the Ordering section of the GraphQL docs).

import { GraphQlHelper, RootSObject } from "salesforce-graphql-helper";

(async function start() {
  const queryHelper = new GraphQlHelper(
    new RootSObject("Account")
      .addField("Id")
      .addField("Name")
      .setOrder("Name", "ASC")
  );
  const response = await queryHelper.query();
})();

Putting it all together:

Example portraying a combination GraphQlHelper functionality.

import { GraphQlHelper, RootSObject, ParentSObject, ChildSObject } from "salesforce-graphql-helper";

(async function start() {
  const queryHelper = new GraphQlHelper(
    new RootSObject("Account")
      .addFields(["Id", "Name"])
      .addFilter({ Name: { like: "Test%" } })
      .setOrder("Name", "ASC")
      .addParentSObject(new ParentSObject("Parent").addField("Name"))
      .addChildSObject(
        new ChildSObject("Contacts")
          .addFields(["Id", "Name"])
          .addParentSObject(new ParentSObject("CreatedBy").addField("Name"))
      )
  );
  const response = await queryHelper.query();
})();

Query Function:

Invoke a Salesforce GraphQL query as a string and optionally pass filters as a variable.

import { query } from "salesforce-graphql-helper";

(async function start() {
  const queryString = `
    query accounts {
      uiapi {
        query {
          Account {
            edges {
              node {
                Id
                Name {
                  value
                }
              }
            }
          }
        }
      }
    }
  `;

  const response = await query(queryString);
})();

import { query } from "salesforce-graphql-helper";
(async function start() {
  const queryString = `
    query accountsWithFilter($where: Account_Filter) {
      uiapi {
        query {
          Account(where: $where) {
            edges {
              node {
                Id
                Name {
                  value
                }
              }
            }
          }
        }
      }
    }
  `;
  const accountNameFilter = { Name: { like: "Test%" } };
  const response = await query(queryString, accountNameFilter);
})();
