Tutorial: Implement Google OAuth 2.0 Login with React, Node.js, and MongoDB

·1 views

A new step-by-step tutorial published on DEV Community walks developers through building a Google OAuth 2.0 login system from scratch. The guide covers setting up API credentials in the Google Cloud Console and writing a secure backend using Node.js and Express. The frontend is built with React and styled using TailwindCSS, while MongoDB handles data storage. Developers are shown how to connect all components into a complete, functional authentication flow. Full source code for the project is available via the creator's Patreon page.

Failure in Business: How to Measure and Minimize Its True Cost

A personal essay on DEV Community explores the real price of failure in entrepreneurship, drawing on the author's own experiences and those of close family members. The author proposes a practical formula: the cost of failure equals its financial, time, and mental impacts combined. Key financial drains are broken down into categories including staffing, physical and digital products, legal obligations, and personal sacrifices such as time away from family. The piece argues that modern business culture favors a 'fail, learn, repeat' approach over the lengthy pre-launch studies of older models. Ultimately, the author frames failure not as an endpoint but as a necessary step toward eventual success, urging entrepreneurs to stay aware of its full cost in order to recover and move forward.

m365-extension-control CLI brings release-intent checks to SPFx estates

A new open-source command-line tool called m365-extension-control has been released to help SharePoint Framework (SPFx) teams verify that on-disk project state matches their declared release intent. The tool uses an estate.json manifest to record ownership, lifecycle status, release channel, and expected version details for each project in an estate. Running commands such as scan, inventory, evidence, and preflight, the CLI compares those declarations against local file facts and reports drift, inconsistencies, and ownership gaps. It outputs deterministic JSON and Markdown evidence with CI-compatible exit codes, but deliberately does not interact with any SharePoint tenant or App Catalog. The project ships with 20 deterministic tests, TypeScript support, and GitHub Actions CI, and is available on GitHub at vystartasv/m365-extension-control.

Agentic AI Acts as Middleware, Translating Human Intent into API Calls

A new engineering perspective argues that agentic AI is best understood not as a chatbot but as a middleware abstraction layer sitting between humans and digital systems. Rather than having users manually navigate multiple SaaS applications, agentic AI interprets natural-language intent and converts it into structured, deterministic API calls. The process relies on large language models acting as semantic routers that extract parameters and generate JSON payloads, while traditional backend systems handle actual execution. To deploy such systems safely, engineers must apply guardrails including least-privilege API access and human-in-the-loop approval for destructive or irreversible actions. The approach frames agentic AI as the next major step in software abstraction, following the evolution from punch cards to GUIs.

Developer Builds Pixel-Art AI Office Where Agents Actually Write Code and Open PRs

A developer built an open-source tool called 'My Little Office' that uses pixel-art characters to represent real AI coding agents assigned to different software roles such as engineer, QA, and tech lead. Each character is backed by actual AI models — including ChatGPT, Gemini, and Grok — that can receive tasks, modify a real codebase, run tests, and open pull requests autonomously. The project began as a playful dashboard concept but evolved when the creator connected agents to a live repository and watched them independently solve coding problems. The creator found that managing these agents shifted their role from writing code to defining problems clearly, setting boundaries, and verifying outputs. This experience prompted a broader reflection on how software development skills may need to evolve as AI handles more of the actual implementation work.
