Top 23 Haskell Open-Source Projects

  • GitHub repo ShellCheck

    ShellCheck, a static analysis tool for shell scripts

    Project mention: using the result of a du in a if statement | reddit.com/r/bash | 2022-01-19

    I was going to suggest https://www.shellcheck.net/ to spot such issues, but apparently it doesn't! (Other than telling File isn't used).

  • GitHub repo Hasura

    Blazing fast, instant realtime GraphQL APIs on your DB with fine grained access control, also trigger webhooks on database events.

    Project mention: If I have a SQL database, what is the easiest way to build a simple website using it? | reddit.com/r/SQL | 2022-01-05

    Second fastest is to use Hasura, which will give a graphql server mapped to your database, and a front end JavaScript framework of your choice.

  • Scout APM

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

  • GitHub repo pandoc

    Universal markup converter

    Project mention: What is the coolest thing you can do in R? | reddit.com/r/Rlanguage | 2022-01-19

    You’re about to be even more mindblown - the conversion to different formats is handled by pandoc in the background (rmarkdown handles the R parts to turn the rmd into “normal” md, then uses pandoc to convert to your desired format). Pandoc has the ability to convert between many formats, not just md -> word. That means you can do all those conversions too, should you need to.

  • GitHub repo postgrest

    REST API for any Postgres database

    Project mention: Five Easy to Miss PostgreSQL Query Performance Bottlenecks | news.ycombinator.com | 2022-01-18

    For OLAP-style use-cases, I wouldn't recommend SQLite, but rather something equally (apparently) unfashionable: stored procedures.

    In both cases, the goal is to save the time spent round-tripping queries and responses to the DB. But with OLAP, you more-than-likely have a large dataset that needs its own dedicated beefy DB to process. So rather than moving the data to the code (with e.g. SQLite), move the code to the data (by moving as much of your business layer as possible into the DB. Or possibly all of it, ala https://postgrest.org/.)

  • GitHub repo compiler-explorer

    Bartosz Milewski's 'Category Theory for Programmers' unofficial PDF and LaTeX source

    Project mention: Lessons Learned from AOC 2021 | dev.to | 2021-12-31

    My definition of functional programming has been shaped by my studies on category theory, particularly through the writings and videos of Bartosz Milewski and others. I enjoyed learning about monoids, functors, monads, algebraic data types, typeclasses, currying, and more. Haskell has been the quintessential functional programming language in my view, and if a language claimed to support functional programming, there were certain features that it needed to have.
