URL to PDF Converter

A simple Node.js program to render a URL as PDF using the ScreenshotOne API.

Prerequisites

• Node.js
• npm
• ScreenshotOne API access key

Installation

1. Clone this repository or download the source code.

git clone https://github.com/screenshotone/examples.git

2. Navigate to the project directory.

cd examples/nodejs/url-to-pdf

3. Install the dependencies:

npm install

4. Create a .env file in the project root directory and add your ScreenshotOne API access key:

SCREENSHOTONE_ACCESS_KEY=your_access_key

You can get your API access key by signing up at ScreenshotOne.

Usage

Basic Usage

Run the program with a URL to convert it to PDF:

node index.js https://example.com

This will generate a PDF file named output.pdf in the project directory.

Custom Output Path

You can specify a custom output path for the PDF file:

node index.js https://example.com /path/to/output.pdf

Retry Mechanism

The application includes a built-in retry mechanism that will automatically retry failed requests up to 3 times with an exponential backoff delay between retries. This helps handle temporary network issues or API rate limits.

You can modify the retry parameters in the main() function in index.js:

const maxRetries = 3; // Maximum number of retry attempts
const retryDelay = 2000; // Initial delay between retries in milliseconds

Advanced Options

You can modify the options object in the main() function in index.js to customize the PDF generation. For a complete list of options, refer to the ScreenshotOne API documentation.
