Samples for the PDF Services Node.js SDK

This sample project helps you get started with the PDF Services Node.js SDK.

The sample JS scripts illustrate how to perform PDF-related actions (such as converting to and from the PDF format) using the SDK. Please note that the PDF Services Node.js SDK supports only server side use cases.

Prerequisites

The sample application has the following requirements:

• Node.js : Version 18.0 or above. Node installation instructions can be found here.

Authentication Setup

The credentials file for the samples is pdfservices-api-credentials.json. Before the samples can be run, set the environment variables PDF_SERVICES_CLIENT_ID and PDF_SERVICES_CLIENT_SECRET from the pdfservices-api-credentials.json file downloaded at the end of creation of credentials via Get Started workflow by running the following commands :

1. For MacOS/Linux Users :

export PDF_SERVICES_CLIENT_ID=<YOUR CLIENT ID>
export PDF_SERVICES_CLIENT_SECRET=<YOUR CLIENT SECRET>

2. For Windows Users :

set PDF_SERVICES_CLIENT_ID=<YOUR CLIENT ID>
set PDF_SERVICES_CLIENT_SECRET=<YOUR CLIENT SECRET>

Client Configurations

The SDK supports setting up custom request timeout for the API calls. Please refer this section to know more.

The SDK also supports setting up Proxy Server configurations which helps in successful API calls for network where all outgoing calls have to go through a proxy else, they are blocked. Please refer this section to know more.

Additionally, SDK can be configured to process the documents in the specified region. Please refer this section section to know more.

Quota Exhaustion

If you receive ServiceUsageError during the Samples run, it means that trial credentials have exhausted their usage quota. Please contact us to get paid credentials.

Build with npm

Run the following command to build the project:

npm install

Note that the PDF Services SDK is listed as a dependency in the package.json and will be downloaded automatically.

A Note on Logging

For logging, this SDK uses the log4js API . Upon running, the SDK searches for a file config/pdfservices-sdk-log4js-config.json in the working directory, and reads the logging properties from there. If no configuration file is provided, default logging, i.e. logging INFO logs to the console is enabled. The clients can change the logging settings as per their needs.

Running the samples

The following sub-sections describe how to run the samples. Prior to running the samples, check that the configuration file is set up as described above and that the project has been built.

The samples code is available under the src folder. Test files used by the samples can be found in the resources folder. When executed, all samples create an output child folder under the project root directory to store their results.
