storybook
Storybook is the industry standard workshop for building, documenting, and testing UI components in isolation
Project mention: 7 Free Tools and Resources for Building Well-Structured React Applications | dev.to | 2026-05-07Storybook is a tool for developing and documenting UI components in isolation. You write stories that render individual components with specific props, and Storybook displays them in a standalone browser environment that is separate from the main application. The v8 release significantly reduced configuration complexity, making it practical to add to an existing project without a major setup investment.

Project mention: Show HN: Files.md – open-source alternative to Obsidian | news.ycombinator.com | 2026-05-18What is this providing over similarly Markdown based open source note taking applications like Joplin? (https://joplinapp.org/)

Project mention: GraphQL vs REST: 18 Claims Fact-Checked with Primary Sources (2026) | dev.to | 2026-04-17
Historically, measurements around 40–45 KB gzipped were reasonable for older Apollo Client bundles , but recent v4.x releases have reduced bundle size and made features more modular. Regardless, that is not a cost of GraphQL itself. The same concern exists for feature‑rich REST clients like SWR or TanStack Query . It is a misleading comparison because both REST and GraphQL can be implemented with nothing more than fetch(). Therefore, the theoretical baseline for both styles is 0 KB.

Zulip
Zulip server and web application. Open-source team chat that helps teams stay productive and focused.
Zulip is building the world’s best collaboration platform, and we’re committed to keeping it 100% open source. Zulip is the only modern team chat app designed for both live and asynchronous conversations. Our product serves as the communication hub for businesses, open-source projects, educators and communities around the world.
We’re looking for a senior backend/infrastructure engineer to join our small core team and build, operate, and scale Zulip — both as we run it on Zulip Cloud, and as thousands of self-hosters run it themselves. The Senior Backend/Infrastructure Engineer will work across backend features, performance, and infrastructure; review code from both staff and open-source contributors; and share responsibility for keeping Zulip Cloud production healthy. You will also have the opportunity to provide technical direction and mentorship to the team.
Check out https://zulip.com/jobs/ to learn more about this and other opportunities at Zulip, and apply at jobs@zulip.com.

I’m doing offline-first apps at work and want to emphasize that you’re constraining yourself a lot trying to do this.
As mentioned, everything fast(ish) is using SQLite under the hood. If you don’t already know, SQLite has a limited set of types, and some funky defaults. How are you going to take this loosey-goosey typed data and store it in a backend database when you sync? What about foreign key constraints, etc., can you live without those? Some of the sync solutions don’t support enforcing them on the client.
Also, the SQLite query planner isn’t great in my experience, even when you’re only joining on ids/indexes.
Document databases seem more friendly/natural, but as mentioned indexeddb is slow.
I wish this looked at https://rxdb.info/ more. They have some posts that lead me to believe they have a good grasp on the issues in this space at least
