Webpack is a great bundler with a steep learning curve. There are so many options that starting to use it is daunting. If you are using this planning on using this yourself, I'd first consider finding a package that implements it for your use case, such as react. If you do end up using it be ready for a lot of reading to fully understand what webpack is doing.
Moment used to be the main library working with dates, but the current performance and best practice standards (immatability) have pushed it to the shadow. If you're maintaining a project with moment - leave it as is, as it's battle tested. If you're starting a new project - choose date-fns.
It does make developers lives easier when it comes to working with dates and times. It also has been a great example of documentation. It got too large for its boots though and there are now a number of alternatives that meets most of people's needs while are much more optimised in terms of bundle size of what users have to download. The other gotchya is that moment is mutable, meaning you need to be careful when trying to test it since if you change the date, it could have unintended consequences and change the date for a test you didn't mean it to. Overall, consider using other libraries (which you can find in their documentation), this should not be your go to date time library, you should look to use something like Luxon or date-fns which are immutable apis and also are more performant.
Incredible package. Dealing with time and timezones is one of the biggest pain points and this makes it a breeze. (Un)fortunately, Temporal proposal should become a replacement for most, if not all, time packages in the near future.
This is great to use for quickly developing and adding amplify features to your project. This tool works great and has easy to use commands. I have seen issues in the past where the maintainers aren't upfront with the community about ongoing issues but I haven't seen that lately.
Great software with intuitive coding design for a great dev experience. The performance is great and scales well. Very easy to integrate with other libraries. Switching between APIs, static pages, and dynamic pages is easy. The coupling of file paths and routes is incredibly easy to use and saves having to manage another dependency.
