cross-cookies

Easily set cross subdomain cookies

Installation

npm install cross-cookies

Usage

// Setup cors `withCredentials`
app.use(require('koa-cors')({
  origin: process.env.OTHER_SUBDOMAIN_URL,
  credentials: true
}))

app.use(require('cross-cookies')())
app.keys = ['zippity', 'doo', 'da']

app.use(function *(next) {
  this.crosscookies('token', 'some token');
})

Note: If you're going to set cookies across subdomains, you're going to need to be able to make requests across subdomains, so you'll need to set up CORS.
