Where should Vue state actually live? It's one of the questions that seems simple until you're three components deep in prop drilling, or debugging a watcher that's silently fighting another watcher for the same source of truth. We put together a cheat sheet that breaks it down clearly: 👉 Component-local state vs. state that needs to survive navigation 👉 When to reach for computed() instead of duplicating data 👉 Pinia store shape (facts, getters, actions) and where teams typically go wrong 👉 An async action checklist for handling loading, error, and stale-response states 👉 How to brief an AI coding agent before it touches your store, so it doesn't guess at your state contract Learn more during Free Weekend on September 26-27: https://lnkd.in/efz88MVr Download the cheat sheet for free: https://lnkd.in/ehw_6GrP

Certificates.dev launches AI-Native Developer Certification today. 🚀 Certificates.dev has released its AI-Native Developer Certification, a new credential aimed at developers who work daily with AI coding tools but have no way to prove it. The certification comes as teams face a familiar problem: someone ends up owning AI workflow decisions (review gates, which agent setups stick, what ships) and it's rarely the most qualified person in the room. The exam is designed to put that judgment on record. A free sample exam is live now at ai.certificates.dev/#exam, so developers can try it before committing. There are three paths to certification, with most candidates opting for the exam bundled with self-paced training, a full trial exam, and a free retake. Early Bird pricing is available for a limited time. Learn more at: https://lnkd.in/eEk37nBv

AI coding agents write Vue faster than you can review it. Automated tests are the feedback loop that keeps those agents honest. This course teaches Vue developers how to test full-stack apps with Vitest by cutting the app at the right seams, not by memorizing syntax. Start learning Vitest for Vue.js devs - new course out now 🔥 https://lnkd.in/eNHKBjxc

AI coding agents write Vue faster than you can review it. Automated tests are the feedback loop that keeps those agents honest. This course teaches Vue developers how to test full-stack apps with Vitest by cutting the app at the right seams, not by memorizing syntax. Within this course, you will learn where to slice a Vue app so each layer is cheap to test: presentational vs container components, components vs composables, browser APIs, the network boundary, REST handlers, services, and the database, etc. Then you will use the Vitest tools that actually fit each layer: unit tests, browser-mode component tests, visual regression, MSW, API tests, and a thin layer of integration and E2E. You will learn: 👉 Why automated testing matters even more when AI agents write the code 👉 Why Vitest is the natural test runner for Vite-based Vue apps, and which of its tools to reach for and when (unit, browser mode, visual regression, type assertions) 👉 How units, seams, and contracts make Vue apps testable (and how tangled components make them a nightmare) 👉 How to split presentational and container components so UI states can be tested without hitting the network 👉 How to extract composables and test logic without mounting the DOM 👉 How to run component tests in a real browser with Vitest browser mode 👉 How visual regression testing catches layout and CSS drift that behavioral assertions miss 👉 How to mock the network with MSW so frontend tests cover loading, error, and empty states on demand 👉 How and what to test in REST API handlers (validation, status codes, response shape, not a dump of business logic) 👉 How to test backend services and data access at the right boundary 👉 How to write a thin, high-value layer of integration and E2E tests (including pages behind an auth wall) 👉 How to wire tests into an AI agent’s loop and how to review agent-written tests Vue developers who already know how to unit-test a pure function and now need a strategy for everything else: components, composables, APIs, databases, and AI-generated code. If you work with Vue 3, Vite, and Vitest, and especially if agents are writing more of your diffs, this course is for you. Get notified when we release the first lessons 🔗 https://lnkd.in/eNHKBjxc
