You can see that it can accept any connect compatible middlewares...
I am trying to implement it as a global, route-less middleware.
https://browsersync.io/docs/options#option-middleware
I added it as a middleware, but I'm getting a TypeError: res.header is not a function
at setHeaders (/Users/.../Sites/sample-site/node_modules/cacher/lib/Cacher.js:166:7)
I used it like:
middleware: [
(new cacher()).cache('seconds', 3000),
// other working middlewares
]
