InfallibleTechie Admin

Using the following Lightning Web Component, we can create a Quick Action to Download All the the files for a record in Salesforce.

Sample code:

Apex Class:

public with sharing class MassDownloadFilesController {
    
    @AuraEnabled( cacheable = true )
    public static List < Id > fetchRelatedFiles( Id strRecordId ) {

        List < Id > listFileIds = new List < Id >();

        for ( ContentDocumentLink objCDL: [ 
            SELECT ContentDocument.LatestPublishedVersionId
            FROM ContentDocumentLink
            WHERE LinkedEntityId =: strRecordId 
        ] ) {

            listFileIds.add( objCDL.ContentDocument.LatestPublishedVersionId );

        }

        return listFileIds;        
        
    }

}

JavaScript:

import { LightningElement, api } from 'lwc';
import { ShowToastEvent } from 'lightning/platformShowToastEvent';
import fetchRelatedFiles from '@salesforce/apex/MassDownloadFilesController.fetchRelatedFiles';  
import { NavigationMixin } from 'lightning/navigation';

export default class MassDownloadFiles extends NavigationMixin ( LightningElement ) {
    
    @api recordId;

    @api invoke() {

        fetchRelatedFiles( { strRecordId : this.recordId } )    
            .then( result => {  
                
                console.log( 'result is', JSON.stringify( result ) );
                if ( result.length > 0 ) {

                    let filesDownloadUrl = '/sfc/servlet.shepherd/version/download';

                    result.forEach( item => {
                        filesDownloadUrl += '/' + item
                    });

                    console.log( 'filesDownloadUrl is', filesDownloadUrl );

                    this[ NavigationMixin.Navigate ]( {

                    }, false );

                    this.dispatchEvent(
                        new ShowToastEvent( {
                            title: 'File(s) Download',
                            message: 'File(s) Download Successfully!!!',
                            variant: 'success'
                        } ),
                    );

                } else {

                    this.dispatchEvent(
                        new ShowToastEvent({

                            message: 'File(s) Download failed!!!',
                            variant: 'error'
                        }),
                    );

                }
    
            } )  
            .catch( error => {  

                this.dispatchEvent(
                    new ShowToastEvent({
                        title: 'File(s) Download Failed',
                        message: 'System Error Occurred',
