browserslist-config-web3

Motivation

Web3 DApps don't need to support things like IE, etc. Using this configuration, you will tell babel/typescript not to support those browsers, thereby reducing polyfills, etc which lead to a smaller compiled output. This means better performance as less javascript is transfered over the wire that has to be parsed by the browser.

Security

Example: Clipboard API is only served via HTTPS

Autoupdating

This package contains an automated CI process to maintain updates see the browserslist workflow file for more info

Browser Support

Using the example above, you can check to see browser coverage by:

npx browserslist ">0.3%, not dead, not op_mini all, not IE > 0"

Returns:

/** @usage */
/** @returns ['>0.3%', 'not dead', 'not op_mini all', 'not IE > 0']; */
