Browser support

Barba can be viewed as a progressive enhancement.

Compatibility

Main modern features used are:

• Promise
• Set() and Map()
• Array.prototype.find
• IntersectionObserver (used by @barba/prefetch)

Cross-browser support is as follows:

• without polyfills: modern browsers (Chrome, Firefox, Edge, Safari, Opera)
• with polyfills for abovementioned: IE10+

Polyfill

You can implement your own solution for polyfilling as well, here are some references you could use:

• core.js
• es6-shim
• es6-promise
