Is it possible to mock [removed] in JavaScript?

Question

document.cookie is like a string, but it is not a string. To quote the example from the Mozilla doc:

document.cookie = \"name=oeschger\";

Answer 1

I know this is an old topic, but in my case expiring cookies was necessary so here's a solution that combines the above answers and a setTimeout call to expire cookies after X seconds:

const fakeCookies = {
    // cookie jar
    all: {},

    // timeouts
    timeout: {},

    // get a cookie
    get: function(name)
    {
        return this.all[ name ]
    },

    // set a cookie
    set: function(name, value, expires_seconds)
    {
        this.all[ name ] = value;

        if ( expires_seconds ) {
            ! this.timeout[ name ] || clearTimeout( this.timeout[ name ] )
            this.timeout[ name ] = setTimeout(() => this.unset(name), parseFloat(expires_seconds) * 1000)
        }
    },

    // delete a cookie
    unset: function(name)
    {
        delete this.all[ name ]
    }    
}
