The most common route trigger is in the form of a user clicking a link within our application. As discussed in the preceding section, we need to equip our link generating mechanism to handle many pages, and many URIs. Another dimension of this scaling influencer is the actual triggering actions themselves. For instance, with smaller applications, there are obviously fewer links. So this also translates to fewer click events from the user—more navigation choices means higher event triggering frequency.

It's also important to consider the lesser known navigation actors. These include redirecting the user in response to some backend task completing, or just a straight-up work-around, to get from point A to point B.
