Liquid Weekly Podcast: Shopify Developers Talking Shopify Development

Recorded live at Shopify's DotDev, this special is two sessions in one. First, Ben Sehl walks Karl and Taylor through the future of Liquid: why the language is being reshaped for the agentic era, the new Partials tag that replaces the section rendering API, arrays and Booleans finally landing, agents.md and design.md guidance, and the Tailwind partnership.

Then we sit down with three Shopify Build Award winners, Sammy of Discount Kit, Harel of EasyTeam, and Emili of Zapiet, to talk about what it actually takes to win, betting early on POS, building for Sidekick, and what's next.

Episode 071 – Taylor Built a Full Shopify Brand with AI in One Afternoon

Karl and Taylor compare how Claude, Codex, and Cursor behave differently when building Shopify discount and checkout UI extensions, and dig into why testing against a real dev store is still such a pain point.

Taylor also walks through spinning up a complete fictitious coffee shop brand, theme, and metaobject data model with Claude Design and Claude Code for his recent DEV conference talk on metaobjects, and shares how a Shopify theme store change quietly broke his Shop Info app.

Plus: a major new identity verification requirement for Shopify Partners requesting collaborator access, updates to app pricing limits and review policy, and this week's picks.

Episode 069 – The Hidden Complexity of Going GlobalKarl and Taylor sit down with Kwadwo (Kojo) Adu, co-founder of LocaleFlow — a bootstrapped Shopify translation app built to help merchants expand into new markets without losing brand voice, SEO, or metafield data. Kojo shares how living in Barcelona as a Dane gave him firsthand empathy for the localization problem, why browser translation falls flat for real stores, and how LocaleFlow's multi-LLM pipeline handles everything from tone-of-voice preservation to currency "nice pricing." The episode rounds out with a Shopify dev changelog covering cart line keys, gift card currency support, and partner dashboard improvements, plus picks featuring a slick diff viewer, an agentic IDE, and a MagSafe truck mount.---Subscribe to Liquid WeeklyDon't miss out on expert insights and tips—subscribe to Liquid Weekly for more content like this: https://liquidweekly.com/---Find Kwadwo Adu OnlineWebsite - https://adu.dkLocaleFlow App - https://localeflowapp.com---
