Common Questions

What are the best backend web frameworks?

Pros

Pro
Offers templating for type-safe, well-formed content

While not required, Yesod offers templating through a Shakespearean family of languages to produce page code.

Pro
Uses type-safe URLs

Ensures that data provided by the URL is type-safe. This means that data in the URL has a definitive type.

Pro
Can be used without knowing much Haskell

While Yesod is written in Haskell, developers can achieve basic functionality without much investment in the language.

Pro
Verbosity

It makes it easy to debug and to read code.

Pro
Mature ecosystem

The language and all its tools have enough time to age and they've aged well.

Pro
Type-safe

It is easier to catch errors sooner.

Ad
Cons

Con
Is hard to customize

Learning how Yesod works internally is hard. It is a large framework with complicated components. Finding the appropriate code and understanding how it contributes to the framework is difficult, meaning developers will struggle.

Con
Too much template haskell

You actually want to code in haskell and not some DSL with "magic" hidden under the bonnet.

Con
Memory hungry

Running the virtual machine, application server and application itself consumes significant amount of resources.

Con
Unnecessarily obtuse and verbose

If you like typing 40 lines of code to open a file, Java is the language for you. If, on the other hand, you’d actually like to get something done, look elsewhere.

Con
Oracle

Enough said.
In more detail: Oracle has acquired Java from Sun and continues to surround it with controversy ever since (legendary lawsuit with google, money extortion from the enterprise users etc.).
