The general philosophy is that you're not wasting time fighting against the [monolithic] framework. In addition, in practice, one size doesn't fit all. For every project and team, you [and the team] have the flexibility to choose the libraries that would be effective for said project. Thus, the ad-hoc framework would generally be different for every project. In general, you [or the team] probably wouldn't re-invent the wheel, and you'll likely to find a decent library on npm.
