Step-by-Step Guide: Build a React To-Do App Connected to Supabase

·1 views

A beginner-friendly tutorial published on DEV Community walks developers through connecting a React application to Supabase, an open-source backend-as-a-service platform. The guide targets those with basic React knowledge and requires no prior Supabase experience to follow along. It covers setting up a Supabase project, creating a PostgreSQL todos table, and integrating the Supabase JavaScript client into a Vite-based React app. The tutorial demonstrates full CRUD functionality — creating, reading, updating, and deleting tasks — using Supabase's auto-generated APIs. Security considerations such as Row Level Security and environment variables for API keys are also briefly addressed.

AI Search Governance Evolves Into Five-Step Framework as Google Deepens AI Integration

Organizations managing content visibility in Google Search now face a more complex challenge as AI-generated answers increasingly replace traditional link-based results. A practical governance framework emerging in 2026 combines five actions: removing content at source, deindexing eligible results, pursuing legal remedies, suppressing remaining exposure, and monitoring AI-generated answers over time. Google's January 2026 updates introduced Gemini 3-based AI Overviews and enhanced AI Mode features, while the UK Competition and Markets Authority proposed a world-first opt-out mechanism allowing publishers to control how their content powers Google's AI search features. These developments reflect a broader shift in which conventional search-result management alone is insufficient when AI systems synthesize and surface information in new ways. Experts caution that the framework represents a sequence of options rather than a guarantee that all unwanted content can be removed, with the right approach depending on content origin, indexing status, and the specific AI surface involved.

Android Test Failures Often Stem From Earlier Crashes, Not Missing UI Elements

Android UI tests can report misleading errors like missing elements or timeouts, which are often symptoms of an earlier application crash rather than the root cause. A demonstration using a synthetic UK weather app shows how a ViewModel binding failure causes the activity to stop rendering, which then triggers the visible test failure. Diagnosing such issues requires reading crash evidence in chronological and causal order, identifying the first actionable exception before addressing downstream errors. In the example, an IllegalStateException from a missing AssistedViewModelFactory binding was the true root cause, not the absent UI element the test framework flagged. Developers are advised to verify ViewModel registration, factory wiring, and existing working patterns in the codebase before applying any fix.

AI Tools Are Disrupting the Traditional Junior Developer Career Path

A widely discussed article by Nazar Boyko, published on DEV Community on July 27, argues that AI has fundamentally damaged the pipeline for junior software developers. The piece suggests that AI coding tools are eliminating the foundational, hands-on learning experiences that historically helped entry-level developers grow their skills. Tasks like manually writing CRUD applications and reading others' code were once essential stepping stones on the developer career ladder. The author contends that by automating these tasks, AI is removing the very struggles that built competent, experienced engineers. The article sparked significant engagement, drawing 170 reactions and a broad discussion within the developer community.

Practical Terminal Tips to Work Faster and Smarter Every Day

A developer has shared a curated set of terminal productivity techniques drawn from daily use, aimed at reducing errors and speeding up workflows. The tips cover keyboard shortcuts like Ctrl+R for history search, shell history expansion operators, and fuzzy-finding tools such as fzf and zoxide for faster navigation. Git aliases, the bat file viewer, and the Perl rename command are highlighted as ways to cut repetitive keystrokes and simplify common tasks. Clipboard piping shortcuts and tmux session management are also recommended, especially for maintaining persistent terminal sessions over SSH. The author suggests starting with fzf and zoxide for the biggest immediate gains, then gradually building up aliases and shortcuts over time.
