Let's generate some PDFs

Why node?

11

• We needed an easy way to convert a web page into PDF

Node has modules for rendering web pages on the server (JSDOM)

Node has modules for PDF generation (PDFKIT)

Why node?

16

We needed a mobile-friendly façade for our non-mobile friendly API

The server is heavily IO bound / async, which node is perfect for.

It is easy and lightweight to spin up API servers and proxies in node. Great support for Auth as well.

node for integration and extensiblity

Log directly to Splunk via TCP,

UDP, HTTP

Integrate search results with other applications using

custom visualizations

Create and run searches from

21

Why node?

22

Inputs by their nature are heavily IO bound and async

Inputs are streaming results back to Splunk and node has great support in the box for streams.

It has a great ecosystem of modules

It’s JavaScript!
