1. Apex: Generate PDF & Save as File (Spring ’26 way)

public with sharing class PdfService {

 @AuraEnabled public static Id generateAndAttachPdf(Id recordId) {

 // Build HTML dynamically String html = '' + '<html>' + '<head>' + '<style>' + 'body { font-family: Arial; font-size: 12px; }' + 'h1 { color: #2E86C1; }' + '</style>' + '</head>' + '<body>' + '<h1>Invoice</h1>' + '<p>Record Id: ' + recordId + '</p>' + '<p>Date: ' + Date.today().format() + '</p>' + '</body>' + '</html>';

 // Convert HTML → PDF (Spring 26) Blob pdfBlob = Blob.valueOf(html).toPdf();

 // Create File (ContentVersion) ContentVersion cv = new ContentVersion(); cv.Title = 'Invoice_' + recordId; cv.PathOnClient = 'Invoice.pdf'; cv.VersionData = pdfBlob; insert cv;

 // Get ContentDocumentId cv = [ SELECT ContentDocumentId FROM ContentVersion WHERE Id = :cv.Id ];

 // Link file to record ContentDocumentLink cdl = new ContentDocumentLink(); cdl.ContentDocumentId = cv.ContentDocumentId; cdl.LinkedEntityId = recordId; cdl.ShareType = 'V'; cdl.Visibility = 'AllUsers'; insert cdl;

 return cv.ContentDocumentId; } }
