How to do conditional browser interactions with intern

Question

With the promised web driver I would like to check if an element exists on the page, then login if it does, otherwise continue with the promise chain.

Is this not possib

Answer 1

In Intern 2, simply use the normal find command:

var remote = this.remote;
remote.get(url)
    .findById('foo')
    .then(function (element) {
        // exists
    }, function () {
        // does not exist
    });

In Intern 1, if you need to conditionally branch, you’ll need to stop and add new instructions based on the result of your check.

var remote = this.remote;
remote.get(url)
    .elementByIdIfExists('foo')
    .then(function (element) {
        if (element) {
            remote.clickElement()
                .type('foo');
                // ...etc.
        }
    });

This should work in Intern 1.1 only if you are adding new commands to the remote promise chain when there are no other already-existing commands pending. Intern 1.2 will contain improvements that eliminate this restriction. This is issue #14.
