HN readers link yesodweb.com for Yesod, a Haskell web framework, and Michael Snoyman's posts on Haskell libraries such as conduit and Warp, usually as examples or support.
- Recommended for · 3 comments
- Conduit posts give insight into thinking with Haskell; the free online book is nice and its docs are current.
Summarised by Claude from a sample of 40 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Yesod is a Haskell web framework for productive development of type-safe, RESTful, high performance web applications.

HN discussionI wrote a long reply, but ended up erasing it and I'll just say that many of these vulnerabilities are due to the programmer using one type (i.e. string) to represent all kinds of data that might be malicious and unsanitized, and then losing track of whether a piece of data is safe for use (e.g. to be sent to DB) or not. I recommend checking out the Yesod web framework [0], which leverages Haskell's strong type syst…

HN discussionI wouldn't call Yesod "anti-haskell". By default, it relies on QuasiQuotes and TemplateHaskell a lot [1], which are extensions to the GHC. So by default, you'd have a hard time running Yesod applications on anything else but GHC (the Glasgow Haskell Compiler). These extensions allow you to write in an EDSL that generates Haskell for you. IMO, Yesod's use of these extensions are a benefit, as it allows the user to ge…

HN discussionSurely just do what ever you'd try to do with another language but just use Haskell instead. Depends on how complex you want to do things. You can just use yesod [0] to create a web app and compare it to an existing one you'd written. An interesting use of Haskell is with concurrency [1], so anything along those lines should give you something pretty awesome. [0]: http://www.yesodweb.com/ [1]: http://chimera.labs.or…

HN discussion> I really like Haskell but I wonder if the type system is actually too strong for the real world. Given the amount of "real world" programming that's been done with Haskell, I suspect not. > Generalizing algorithms sounds nice but if Haskell is so powerful, why is the Haskell community still not able to provide a convenient working package manager? I don't see a real problem with Cabal with sandboxes. > Perl has CP…

HN discussionYes, Hamlet does context specific escaping. It will handle all the examples given, except you can't mix your javascript in with your html (which is generally good advice anyways). I disagree with the articles premise that injection is always a display issue. In the [Yesod web framework]( http://www.yesodweb.com ) which uses Hamlet, we sanitize , not strip html by default before it is ever put in the database. The mo…

HN discussionYou don't know where "doc" is coming from from a snippet like that. I use logic moderately similar to that for my blog software. If I'm writing the blog post, pretty much pass through what I wrote. If it's a comment (back when I had them), process the heck out of it. The blog post itself is a blob of HTML, basically. I do not currently write my blog posts in a templating language (any more than anyone else does), th…

HN discussionYes. In some ways I think we're still in a very primative kind of level for web development. Either you do it by hand, tweaking each individual parameter like the old demoscene, and making it fast and amazingly small, or else you write huge chunky slow web apps, or more usually, something in the middle. I feel like the big thing I'm missing is smart compilers that can take web app concepts, and turn them into extrem…

HN discussionLooks like Persistent has no support for table joins...bit of a show stopper that, but there's a companion library[1] which looks quite powerful (similar to Scala's Slick wrt to type safety and composability). Can't say I care for the syntax much (`^.`, `where_`, etc.) but I guess that's par for the course in Haskell given the open world (i.e. module system leaves something to be desired relative to OCaml and SML).…

HN discussion>Edit: even Haskell seems to be about 7x faster than Erlang (according to [1]). Suddenly, Haskell looks like a good candidate for writing a distributed server :) Can somebody comment on this? One of the best kept secrets of Haskell, it can be very fast, supports multiple concurrency/parallelism options. The Yesod team does interesting performance work on the Warp server: http://www.yesodweb.com/blog/2014/02/new-warp…
