IHP (Web framework)
IHP (short for Integrated Haskell Platform) is a server-side web framework written in Haskell.[1][2] IHP follows the model-view-controller (MVC) architectural pattern. It is considered a Batteries Included web framework and designed to be beginner friendly for new Haskell developers.[3][4][5] IHP is an affiliate of the Haskell Foundation.[6]
Internally IHP is using the Warp Web server and uses a built-in ORM as its persistence layer.[7] IHP comes with many built-in code generators to speed up and simplify the process of building web applications. It comes with a visual database schema designer and also allows management of the schema by specifying the DDL statements that make up the database.[8][9] On the view layer IHP uses its own HTML markup Domain-specific language, which is called HSX in analogy with React JSX, but transforms to type-checked Haskell code as a step before HTML generation.[10][11] Instead of a custom monad transformer stack, which is common for Haskell applications, IHP makes use of Implicit Parameters to pass the database connection or current request around.[12]
IHP uses Nix package manager to have a deterministic development environment, including its integrated PostgreSQL database, compiler (GHC), and other tools. In production, the use of Nix allows for reproducible builds.[13][14]

Deployment
Applications built with IHP can be deployed on NixOS servers[16], by using the IHP Cloud service[17] or with Docker (software).[18]
