Node+JS Interactive

Last year at PayPal, we open-sourced our suite of cross-domain JavaScript libraries — including xcomponent, post-robot, and other tools we use to power our cross-domain web components.

This year we've been upleveling our SDK from a static CDN script to a fully dynamic resource, embracing serverless principles and shipping a custom-tailored JavaScript bundle for each client. We'll talk about:

- How we're running webpack and babel on the server to dynamically transpile and bundle our code.
- How we're using npm to deploy and activate new code, and avoiding redeploying entire pools of servers.
- How our SDK is tailored to load only the code, images, configuration, and localization each client needs, without lazy-loading slowing down our renders.
- How we're shipping our SDK with evergreen versioning while keeping it upgradeable and future-proofed.
