Image to PDF in Node.js

Overview

The official PDFCrowd Node.js client library provides access to the Image to PDF API.

npm install pdfcrowd

git clone https://github.com/pdfcrowd/pdfcrowd-nodejs
cd pdfcrowd-nodejs
npm link

Quick Start

The examples below cover the basic conversion flow. See additional examples for more scenarios.

var pdfcrowd = require("pdfcrowd");

// Create an API client instance.
var client = new pdfcrowd.ImageToPdfClient("demo", "demo");

// Run the conversion and save the result to a file.
client.convertFileToFile(
    "/path/to/logo.png",
    "logo.pdf",
    function(err, fileName) {
        if (err) return console.error("PDFCrowd Error: " + err);
        console.log("Success: the file was created " + fileName);
    });

var pdfcrowd = require("pdfcrowd");

// Create an API client instance.
var client = new pdfcrowd.ImageToPdfClient("demo", "demo");

// Run the conversion and save the result to a file.
client.convertUrlToFile(
    "https://pdfcrowd.com/static/images/logo.png",
    "logo.pdf",
    function(err, fileName) {
        if (err) return console.error("PDFCrowd Error: " + err);
        console.log("Success: the file was created " + fileName);
    });

var pdfcrowd = require("pdfcrowd");
var fs = require("fs");

// Create an API client instance.
var client = new pdfcrowd.ImageToPdfClient("demo", "demo");

// Run the conversion and save the result to a file.
client.convertRawDataToFile(
    fs.readFileSync("/path/to/logo.png"),
    "logo.pdf",
    function(err, fileName) {
        if (err) return console.error("PDFCrowd Error: " + err);
        console.log("Success: the file was created " + fileName);
    });

Error Handling

It is recommended that you implement error handling to catch errors the API may return. Effective error handling is vital as it ensures application stability and provides clearer diagnostics. See the example code below for guidance on implementing error handling, and refer to this list of status codes for more information.

try {
    // Call the API 
}
catch(why) {
    // Log the complete error
    console.error("PDFCrowd Error: " + why);

    // Log the HTTP status code
    console.error("Status Code: " + why.getStatusCode());

    // Log the reason code
    console.error("Reason Code: " + why.getReasonCode());

    // Log the error message
    console.error("Error Message: " + why.getMessage());

    // Log the documentation link
    console.error("Documentation Link: " + why.getDocumentationLink());
}

Troubleshooting

• If you are receiving an error, refer to the API Status Codes for more information.
• Use setDebugLog() and getDebugLogUrl() to obtain detailed information about the conversion process, including load errors, load times, browser console output, etc.
• Consult the FAQ for answers to common questions.
• Contact us if you need assistance or if there is a feature you are missing.
