| Abstract | The development of robust and efficient interactive web applications is challenging, because developers have to deal with multiple programming languages, asynchronous events, propagating data and events between clients and servers, data consistency and much more. Several approaches for (partly) addressing these challenges have been proposed. Two relevant ones are (1) multi-tier languages and (2) functional reactive programming (FRP). Multi-tier programming languages support the development of client and server in a single language, and hide much of the complexity related to distribution. FRP offers the right abstractions to make event-driven programming convenient, safe and composable. However, existing web frameworks and programming languages exploit the benefits of both approaches separately, for example by restricting the use of FRP to the client side. We propose multi-tier FRP for the Web, a novel approach to writing web applications that deeply integrates FRP and multi-tier languages, and where the whole is greater than the sum of its parts. In multi-tier FRP, the developer programs server and client together as an FRP application composed of behaviors (signals) and events. He/she chooses explicitly where the boundary between server and client is crossed. To make our approach more concrete and provide evidence of its potential, this paper presents a concrete design and implementation of a multi-tier FRP API for the web in the programming language Scala, using an embedded JavaScript DSL that makes Scala usable as a multi-tier language. This allows us to present initial evidence of the benefits of the multi-tier FRP approach on example applications, and to experiment with possible answers to the remaining questions. Concretely, we show possible solutions for problems like exposing client identity on the server and efficiently pre-loading clients with the latest application state. Our results show that multi-tier FRP is a promising, declarative, yet practical way of writing web applications. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
