Links is a functional programming language designed to make web programming easier.
Links eases building interactive web applications with significant client- and server-side components.
Links incorporates proven ideas from other programming languages: database-query support from Kleisli, web-interaction proposals from Racket, and distributed-computing support from Erlang. On top of this, it adds new web-centric features of its own.
The initial Links development effort was funded by EPSRC grant EP/D046769/1 from 2005-2009. In 2014 development on Links resumed with a focus on adding session types to Links, funded by EPSRC Programme Grant "From Data Types to Session Types: A Basis for Concurrency and Distribution" (EP/K034413/1). Other active areas of research which are driving Links development include work on adding algebraic effects and effect handlers to Links (UKRI Future Leaders Fellowship EHOP, grant number MR/T043830/1) and the Skye project, which builds on Links to support scientific data curation (funded by the European Research Council, grant number 682315.
