## Overview

This example demonstrates how to use Trigger.dev to generate a PDF using [react-pdf](https://react-pdf.org/) and save it to Cloudflare R2.

|
|
## Task code
|
|
|
|
<Info> This example must be a .tsx file to use React components.</Info>
|
|
|
|
```ts trigger/generateResumePDF.tsx
|
|
import { logger, task } from "@trigger.dev/sdk";
|
|
import { renderToBuffer, Document, Page, Text, View } from "@react-pdf/renderer";
|
|
import { PutObjectCommand, S3Client } from "@aws-sdk/client-s3";
|
|
|
|
// Initialize R2 client
|
|
const r2Client = new S3Client({
|
|
// How to authenticate to R2: https://developers.cloudflare.com/r2/api/s3/tokens/
|
|
region: "auto",
|
|
endpoint: process.env.R2_ENDPOINT,
|
|
credentials: {
|
|
accessKeyId: process.env.R2_ACCESS_KEY_ID ?? "",
|
|
secretAccessKey: process.env.R2_SECRET_ACCESS_KEY ?? "",

|
},
|
|
});
|
|
|
|
export const generateResumePDF = task({
|
|
id: "generate-resume-pdf",
|
|
run: async (payload: { text: string }) => {
|
|
// Log the payload
|
|
logger.log("Generating PDF resume", payload);
|
|
|
|
// Render the ResumeDocument component to a PDF buffer
|
|
const pdfBuffer = await renderToBuffer(
|
|
<Document>
|
|
<Page size="A4">
|
|
<View>
|
|
<Text>{payload.text}</Text>
|
|
</View>
|
|
</Page>
|
|
</Document>

);
|
|
|
|
// Generate a unique filename based on the text and current timestamp
|
|
const filename = `${payload.text.replace(/\s+/g, "-").toLowerCase()}-${Date.now()}.pdf`;
|
|
|
|
// Set the R2 key for the PDF file
|
|
const r2Key = `resumes/${filename}`;
|
|
|
|
// Set the upload parameters for R2
|
|
const uploadParams = {
|
|
Bucket: process.env.R2_BUCKET,
|
|
Key: r2Key,
|
|
Body: pdfBuffer,
|
|
ContentType: "application/pdf",

};
|
|
|
|
// Log the upload parameters
|
|
logger.log("Uploading to R2 with params", uploadParams);
|
|
|
|
// Upload the PDF to R2
|
|
await r2Client.send(new PutObjectCommand(uploadParams));
|
|
|
|
// Return the Bucket and R2 key for the uploaded PDF
|
|
return {
|
|
Bucket: process.env.R2_BUCKET,
|
|
Key: r2Key,
|
