The cssdb npm package is a comprehensive database of CSS features and their stages in the CSS standardization process. It provides a structured list of current, upcoming, and experimental CSS features, making it a valuable resource for developers looking to stay up-to-date with the latest in CSS or to polyfill future CSS features. The package can be used to programmatically access information about CSS features, their specifications, and implementation status across different browsers.

What are cssdb's main functionalities?

Accessing CSS feature data

This code sample demonstrates how to import the cssdb package and retrieve an array of CSS features. Each feature in the array includes details such as the feature's name, description, stage in the standardization process, and links to the specification.

const cssdb = require('cssdb');
const features = cssdb();
console.log(features);

Filtering CSS features by stage

This example shows how to filter CSS features by their stage in the standardization process. In this case, it filters for features that are at stage 2, which represents a draft state where the feature is still under discussion.

const cssdb = require('cssdb');
const stage2Features = cssdb().filter(feature => feature.stage === 2);
console.log(stage2Features);

cssdb

cssdb is a comprehensive list of CSS features and their positions in the process of becoming implemented web standards.

Did you come here to update the status of a CSS feature or add a new one? Quick, read CONTRIBUTING.md.

Did you come here to learn about the stages? Quick, read STAGES.md.

cssdb ranks CSS features by stages that reflect the real-life stability of new CSS features.

You can read an inside view of the CSSWG to learn about the official (and unofficial) development stages of CSS specifications. In reality, specifications and browser implementations happen out of sync. For example, there are stable CSS features missing in all browsers, while other CSS features developed outside the CSSWG have appeared in browsers behind flags. This is too ambiguous for the web development community, and a more accountable process is desired.
