#Koa StatelessAuth

This is a stateless auth library for koa. If there is no Authorization header or if is empty it will return 401 status code. The library accepts a validator object with a validate function. Pass in your own object to determine how it validates. If the validator does not return a user object a 401 is returned; You can also pass in an optional options object that can define paths to ignore and therefore yield to the next function without validating the request.

##Usage

var statelessauth = require('statelessauth');
var validator = {
    validate: function (token) {
        //This should go to a DB etc to get your user based on token
        if (token === '123') {
            return;
        }
        return {
            "name": "bob",
            "role": "admin",
            "email": "bob@acme.com"
        };
    }
};
var statelessauthOptions = {
    ignorePaths: ["/", "/nonsecure"]
};
app.use(statelessauth(validator, statelessauthOptions));
app.use(function * (next) {
    if (this.user) {
        console.log(this.user.name);
        console.log(this.user.email);
        console.log(this.user.role);
    }
    yield next;
});
