Core Web Vitals are critical for both rankings and user experience. If your site fails these metrics, it can directly impact your visibility in search engines.
This guide shows developers exactly how to fix them.
What Are Core Web Vitals?
Core Web Vitals measure real-world user experience:
Technical SEO is where development and search visibility meet. You can have great content, but if your site is slow, unstructured, or hard for search engines to crawl, you’ll struggle to rank.
This checklist is designed specifically for developers working with PHP, Symfony, Drupal, or any modern web stack.
1. Site Speed & Performance
Performance is a ranking factor and directly impacts user experience.
I recently spent an afternoon building an enterprise CRM from scratch using Claude Code — Anthropic's A I coding assistant that runs directly in your terminal. The stack: Symfony 7 on the backend with API Platform, React 18 with TypeScript on the frontend, PostgreSQL, and Docker Compose to tie it all together. Here's what I actually learned.
What We Built
In a single session we scaffolded a full CRM with:
Emacs, a versatile and powerful text editor, offers numerous features to enhance productivity. By customizing your Emacs configuration, you can streamline your workflow and boost efficiency. In this article, we will explore various tips and tricks for configuring Emacs to increase productivity and efficiency.
Modern software projects are getting bigger. Monorepos, microservice architectures, vendor dependencies, and generated code can easily push projects into tens of thousands of files. Without the right workflow, even powerful editors like Emacs can become slow or overwhelming.
Fortunately, Gnu Emacs provides excellent tools for managing large projects efficiently—if you configure and use them correctly. This article shows practical techniques to keep Emacs fast, responsive, and scalable for large codebases.
Emacs Lisp (Elisp) is a small, elegant Lisp dialect that powers Emacs. Even if you’re not writing full Emacs packages, understanding a few essential constructs can help you automate tasks, customize your editor, and write smarter configuration code.
In this article, we’ll explore some of the most useful, everyday Elisp building blocks that every Emacs user should know — with small, practical examples you can immediately paste into your config.
Keeping your Emacs packages up to date is essential if you want the latest features, performance improvements, and security fixes. But manual updates can quickly become a chore — especially if you use Emacs as your main development environment and rely on dozens of packages.
Learn how to reduce load times, improve scalability, and cache smartly using Symfony’s built-in HTTP caching tools, Edge Side Includes (ESI), and the Varnish reverse proxy.
Why HTTP caching matters
HTTP caching sits between your users and your backend, serving popular pages directly from memory without hitting PHP. With proper caching headers, you can reduce server load and deliver content in milliseconds instead of seconds.
Symfony is built around a simple but powerful idea: everything is a bundle. A bundle is a self-contained package of code — controllers, entities, services, and templates — that can be reused across multiple projects.
In this guide, we’ll walk through how bundles work, how to create your own, and how they fit into a modern Symfony 7 application.
