nuxt-polyfill
Ease adding polyfills to your Nuxt.js project.
Requires Nuxt >= 2
Features
- ✔ Easy to configure
- ❔ Lazy load polyfills only if needed by using
Feature Detection
- ⚡️ Aims to be as fast as possible
- 🔧 Supports any polyfill as NPM package or JS file
- ⭐️ Supports polyfills from polyfill.io
- Detect function can be called before loading the features
- Polyfills are not included in the bundle but loaded separately
Getting started
npm install nuxt-polyfill
Add the module to your nuxt.config.js
:
export default {
// Configure polyfills:
polyfill: {
features: [
/*
Feature without detect:
Note:
This is not recommended for most polyfills
because the polyfill will always be loaded, parsed and executed.
*/
{
require: 'url-polyfill' // NPM package or require path of file
},
/*
Feature with detect:
Detection is better because the polyfill will not be
loaded, parsed and executed if it's not necessary.
*/
{
require: 'intersection-observer',
detect: () => 'IntersectionObserver' in window,
},
/*
Feature with detect & install:
Some polyfills require a installation step
Hence you could supply a install function which accepts the require result
*/
{
require: 'smoothscroll-polyfill',
// Detection found in source: https://github.com/iamdustan/smoothscroll/blob/master/src/smoothscroll.js
detect: () => 'scrollBehavior' in document.documentElement.style && window.__forceSmoothScrollPolyfill__ !== true,
// Optional install function called client side after the package is required:
install: (smoothscroll) => smoothscroll.polyfill()
}
]
},
// Add it to the modules section:
modules: [
'nuxt-polyfill',
]
}
Note: You need to install the NPM packages manually.
In order to run this example:
npm i url-polyfill intersection-observer smoothscroll-polyfill
