When you build for the web, you have to make many different choices. What am I going to build? What tools are I going to use? The number of tools, frameworks and libraries available can be overwhelming.
JavaScript is no exception. You have a wide variety of JavaScript frameworks or libraries to choice from. Should you use these technologies for every project? HTML and CSS can now do many things that you once needed JavaScript to do.
What is the Lean Web?
The Lean Web is a set of simple web development principles. Best practices for building the web with HTML, CSS and JavaScript. Chris Ferdinandi who wrote the Lean Web encourages you to embrace the web as a platform. To let the browser to do what it does best.
Chris gave a talk on Lean Web at WordCamp LA 2020.
The Three Lean Web Principles
Principle 1. Embrace the Platform
Use HTML over JS, CSS over JS and use the browser for what it is good at. Does that mean you shouldn’t use new tools and technologies? No. You need to decide when you should use them and why.
Principle 2. Small & Modular
Look for small, focused tools that do one thing really well. Use APIs, native browser methods or alternative tools lie Svelte or Preact. Use utility-first CSS to prevent redundancy in your stylesheets.
Principle 3. The Web is for Everyone
Not all browsers support native features. You can use a polyfill to replicate the feature. As developers, we make choices that can break the web for some people. Chris suggest using the A11Y Project to make sure that everyone who wants to use your web applications can.
Summary
You don’t want to avoid using new tools, frameworks and techniques in favor of old ways of doing things. When you are building any project, you have to make choices on what to use. Sometimes, HTML and CSS is the better choice.
