Is the use of these modules a sign of good taste in the development of complex applications?

Question

Angular

It is required to develop a highly loaded one-pager with high performance on the client. If we use the following components, won't we get a bunch of unnecessary code, crutches, etc., which will eventually lead development to a dead end in terms of performance?
- yeoman
- bower
- grunt
- angular-generator
Application includes search, large lists, forms, etc.

Answer 1

Generators are evil, in my opinion.
grunt/bower - fire.
Collect, aglyfait, test - all that is needed.

Answer 2

All of the utilities described above are developer tools and do not affect the performance of the client code in any way. If everything is done correctly and optimized where necessary, then it will work quickly.
As for generators, you use them only once, when creating a project. You can use it when you find something you don't like, then change it.
For building js, parts of the grunt/gulp project are the optimal solution. Look in the direction of gulp, it is ideologically correct than the ground, but it has fewer additions.
