Introduction

The main concept included in this recipe is using the getrecord adapter to retrieve record’s data.

The getrecord belongs to the 'lightning/uiRecordApi' module. The accepted parameters are basically the record Id and the fields to retrieve using an array.

For a full explanation on the parameters, check this page getRecord - Salesforce Lightning Component Library.

The results are returned to dataand error properties.

Template file

The template shows the value in the property named recordStrwhen the property record.datais not empty.

Using the same approach, errors are shown when the property record.error has any value and record.data is empty, using the new syntax elseif.

	<div class="slds-var-m-horizontal_medium">
	    <template lwc:if={record.data}>
	        <div class="scroller">
	            <pre>{recordStr}</pre>
	        </div>
	    </template>
	    <template lwc:elseif={record.error}>
	        <c-error-panel errors={record.error}></c-error-panel>
	    </template>
	</div>

Javascript file

In the importsection, there are 3 different modules imported:

//This import is providing the wire adapter
import { getRecord } from 'lightning/uiRecordApi';

//Those 2 imports are statically importing fields from the User object
import NAME_FIELD from '@salesforce/schema/User.Name';
import EMAIL_FIELD from '@salesforce/schema/User.Email';

//This import is refering the the User object also, but in a particular way
import Id from '@salesforce/user/Id';

It is particularly interesting this import Id from '@salesforce/user/Id' as it is used to import the current logged user's Salesforce Id. By importing Id from this module, you can access the Salesforce ID of the current user and use it within your LWC.

After the import, the crucial part is invoking the getRecordwired adapter:

• the required recordIdrequired parameter assigned to the reactive $userId
• the fieldsand optionalFieldsare passed using the statically imported fields

Assigning the reactive property to the recordId parameter makes a new every time the userId changes.
