Senior Product Lead @Shopify, building Shopify Functions

Joined April 2009
Incredibly excited for this launch🚀 The opportunity has never been greater for partners to build entirely new solutions for merchants. Let's get building 🏗️
I've been talking a lot about infrastructure lately, so let me highlight one piece that I'm especially excited about: Shopify Function. We want to make the import easy and everything else possible. Until now, the backend was closed. Thanks to Web Assembly we can change that.

Great set of tips here by Jonathan if you’re working with Functions
I hit Shopify Function size limit at least 50 times during last two months. So I spent 50+ hours figuring out every possible hack to squeeze my code down. Here's my playbook for shrinking Shopify Functions:🧵👇
