Merge

This documentation provides an example of how to use the FileforgeClient to generate combine multiple PDFs into one.

Prerequisites

Ensure you have the following:

  • An API key for Fileforge as an environment variable: process.env.FILEFORGE_API_KEY
  • Node.js and npm installed.
  • The Fileforge Client installed.

Guide

1

Make sure to set a timeout for the request

If you are merging many / very large files, you may need to increase the timeout as shown below with the timeoutInSeconds parameter.

Merge the PDFs

1import { FileforgeClient } from "@fileforge/client";
2import * as fs from "fs";

5    const ff = new FileforgeClient({
6      apiKey: process.env.FILEFORGE_API_KEY,

10      const pdfFiles = [
11        fs.createReadStream(__dirname + "/pdf1.pdf"),
12        fs.createReadStream(__dirname + "/pdf2.pdf"),
13      ];
14      const mergedPdfStream = await ff.pdf.merge(
15        pdfFiles,
16        {
17          options: {
18            // Specify merge options if any
19          },
20        },
21        {
22          timeoutInSeconds: 60,
23        },
24      );
25      mergedPdfStream.pipe(fs.createWriteStream("./result_merge.pdf"));
26      console.log("PDF merge successful. Stream ready.");
27    } catch (error) {
28      console.error("Error during PDF merge:", error);
29      throw error;
