How to Use the URL to PDF Microservice

Apr 7, 2022 | Programming

The URL to PDF Microservice is a versatile tool designed for converting any webpage or HTML content into PDF format. It can be particularly useful for creating invoices, receipts, or any other content that needs to be rendered in a PDF format. In this article, we’ll guide you through the simple steps to set up and use this microservice effectively.

Getting Started

To start converting URLs to PDFs, you can easily deploy the microservice to Heroku or set it up locally. Here’s how:

1. Deploying to Heroku

Follow these steps to deploy on Heroku:

2. Local Setup

If you prefer to run the service locally, follow these steps:

  • Clone the repository: git clone https://github.com/alvarcarto/url-to-pdf-api.git
  • Change directory to the cloned repository: cd url-to-pdf-api
  • Copy the environment sample: cp .env.sample .env
  • Edit the .env file to configure your environment variables.
  • Install dependencies: npm install
  • Start the local server: npm start
  • Access the service locally at http://localhost:9000

Using the API

The microservice provides a simple API for converting a URL to a PDF. You can do this using a GET request:

GET /api/render?url=http://google.com

You can also set additional options, such as output format or wait times using query parameters.

Example Requests

Here are some example requests you can try:

  • To render a webpage to a PDF: http://url-to-pdf-api.herokuapp.com/api/render?url=http://google.com
  • To take a screenshot instead: http://url-to-pdf-api.herokuapp.com/api/render?output=screenshot&url=http://google.com
  • To wait for an element to appear before rendering: http://url-to-pdf-api.herokuapp.com/api/render?url=http://google.com&waitFor=input

How It Works: The Analogy

Imagine the microservice as a chef in a restaurant. The chef (the microservice) takes an order (the URL you want to render) and prepares a dish (the PDF document) based on that order.

  • First, the chef checks the order for any special requests (like waiting for elements to load or choosing between PDF and PNG).
  • Next, the chef gathers the ingredients (the webpage content), ensuring everything is fresh (loaded and rendered within a Chrome-based environment).
  • Finally, the chef presents the dish beautifully on a plate (the rendered PDF), ready for the customer to enjoy!

Troubleshooting

If you encounter issues while using the service, consider the following troubleshooting tips:

  • Ensure you are passing the correct URL format, starting with http:// or https://.
  • If you experience delays or crashes, inspect the server memory, especially when rendering heavy pages.
  • Check your Heroku app logs for any errors that may arise during requests.
  • If the service does not respond, confirm that your local environment is set up correctly or that your Heroku app is running.
