In Salesforce LWC, you can fetch and display data from various sources, such as Salesforce objects (like Accounts or Contacts), external APIs, or custom Apex controllers.

Here’s a step-by-step guide on how to fetch and display data in a Salesforce LWC:

Create a Lightning Web Component:

If you haven’t already, create an LWC in your Salesforce environment. You can do this through the Salesforce Developer Console or your integrated development environment (IDE).

Define a Property to Hold Data:

In your Salesforce LWC JavaScript file (e.g., myLWC.js), define a property to hold the fetched data. For example:

import { LightningElement, track } from ‘LWC’;

export default class MyLWC extends LightningElement {

    @track records; // Property to store the fetched data


Fetch Data:

You can fetch data using the fetch() method for external APIs or by using Apex methods for Salesforce data. For example, to fetch records from a custom Apex method:

import { LightningElement, track, wire } from ‘lwc’;

import fetchDataFromApex from ‘@salesforce/apex/MyController.fetchDataFromApex’;

export default class MyLWC extends LightningElement {

    @track records;


    wiredData({ error, data }) {

        if (data) {

            this.records = data;

        } else if (error) {

            console.error(‘Error fetching data: ‘, error);




In this example, fetchDataFromApex is an Apex method that you need to create in your Salesforce org.

Display Data in the Template:

In your LWC HTML file (e.g., myLWC.html), use the data property you defined to display the fetched data.


    <lightning-card title=”Fetched Data”>

        <div class=”slds-m-around_medium”>

            <template if:true={records}>


                    <template for:each={records} for:item=”record”>

                        <li key={record.Id}>{record.Name}</li>




            <template if:false={records}>

                No records found.





In this example, we’re displaying a list of records’ names. You can customize the template to suit your needs.

Deploy and Test:

Deploy your LWC to your Salesforce org.

Add the LWC to a Lightning App Page or another suitable location.

Test your component to ensure that it correctly fetches and displays data.

Handle Errors:

Always include error handling in your LWC to handle cases where data fetching fails. This ensures a better user experience.

That’s a basic overview of how to fetch and display data in a Salesforce Lightning Web Component. Depending on your requirements, you may need to use different techniques, such as pagination, sorting, or filtering, to enhance the functionality of your component.
