caniuse-db

What is caniuse-db?

The caniuse-db npm package provides a database of browser support for various web technologies. It is a programmatic interface to the data available on the Can I use website, which is a popular resource for web developers to check the compatibility of web features across different browsers.

What are caniuse-db's main functionalities?

Querying Browser Support Data

This feature allows you to query the database for support information on specific web technologies. In this example, we are checking the support data for CSS Grid.

const caniuse = require('caniuse-db/data.json');

// Example: Check support for CSS Grid
const cssGridSupport = caniuse.data['css-grid'];
console.log(cssGridSupport);

Accessing Browser Versions

This feature provides access to the list of browsers and their versions that are included in the Can I use database. This can be useful for understanding which browsers are being tracked.

const browsers = require('caniuse-db/browsers');

// Example: List all browsers and their versions
console.log(browsers);

Checking Feature Status

This feature allows you to check the status of a specific web technology feature, such as whether it is in development, under consideration, or fully supported.

const statuses = require('caniuse-db/statuses');

// Example: Get the status of a feature
const featureStatus = statuses['css-grid'];
console.log(featureStatus);

Other packages similar to caniuse-db

browserslist

Browserslist is a tool that allows you to specify which browsers you want to support in your project by querying a list of browsers. It is often used in conjunction with tools like Autoprefixer and Babel to ensure compatibility with the specified browsers. Unlike caniuse-db, which provides detailed support data for individual web technologies, Browserslist focuses on defining and querying browser support configurations.

mdn-browser-compat-data

The mdn-browser-compat-data package provides compatibility data for Web technologies as displayed on MDN Web Docs. It includes data for HTML, CSS, JavaScript, and other web APIs. This package is similar to caniuse-db in that it provides browser support information, but it is sourced from MDN and may have different coverage and data structure.
