get-focusables v1.2.0

get-focusables

Get focusable or tabbable elements within a DOM node

Versions

The package includes versions for ES6+ and ES5, both as an ESM module (browser-compatible) and a CJS module (npm-compatible).

Here's the included file variants:

Each version gives you the getFocusableElements function.

get-focusables is written in ES6 syntax and packaged node-style. It is converted to ES5/ESM for wider distribution. The default is therefore the ES6 CJS variant index.js.

NOTE In order to get a non-default version, you will need to tell your bundler to use index.mjs/es5.js/es5.mjs instead of index.js. For webpack, that's { resolve: { alias: { 'get-focusables': 'get-focusables/es5.mjs } } }'
