It is not obvious to me which one you are talking about.

The framework solution will end up costing more over the life of your application due to artificial restrictions, leaky abstractions, extra dependencies, performance decreases, and more code to maintain. In most cases all of those are acceptable if the developers are less comfortable making original architectural decisions.

For me that comfort is achieved through reuse and audits around data structure types through use of TypeScript. Now that ThpeScript is natively supported in Node it’s even faster still because there is no need for a build or compile step. The code just runs as is. This is also even true for code that executes only in the browser so long as it’s imported into a node module, which I do anyway to reduce the number of file requests into the browser.
