GraphQL Pagination Example

This repository contains an example implementation of pagination using GraphQL in a Lightning Web Component (LWC) for Salesforce.

It's part of a Tutorial on GraphQL in Salesforce hosted by Panther Schools and Amit Singh

The YouTube series can be found here

Their source code hosted in GitHub can be found here

Components

GraphQLQuery.js

This file contains the JavaScript code for the GraphQLQuery Lightning Web Component. It implements pagination using GraphQL queries and Lightning Web Components.

Features:

  • Pagination forward and reset page # using GraphQL cursors.
  • Dynamically updating datatable with queried data.
  • Search functionality to filter contacts by name.

graphQLQuery.html

This file contains the HTML template for the GraphQLQuery Lightning Web Component. It includes the UI elements like search input, datatable, and pagination buttons.

Features:

  • Lightning Datatable to display queried contacts.
  • Pagination buttons to navigate through pages of contacts.
  • Lightning Spinner to indicate loading state.

How to Use

  1. Clone the repository to your local machine:
git clone https://github.com/tomsouza4/QueryGraphQLOnLWC.git

Output Sample

QueryGraphQLOnLWC.mov

Important Note

In this app theres no pagination backwards and this is due to current limitation on Salesforce GraphQL API. Which is currently in GA as Jan/2024.

Additional Note

Currently the API supports Mutations(Create, Update, Delete) only in Development, it will be available in Production in future releases.

Nice to Haves

Benchmark performance comparing GraphQL to other formats of queries.

  • Query data using native LWC to get Records such as '@salesforce/schema/Contact'.
  • Custom Apex Class to query data from Salesforce.
