Manipulate 'JSON' Data in the Browser with a 'dplyr' Interface R package jsplyr version 0.1.0 A 'dplyr' backend for 'shiny' applications that manipulates 'JSON' data in the web browser instead of on the server. Data manipulation verbs such as filter, select, mutate, summarise, arrange, and joins are evaluated lazily and translated into 'JavaScript' operations that run client-side, following the lazy evaluation approach of 'dbplyr' but generating 'JavaScript' rather than 'SQL'. Results are returned to R asynchronously as promises. This keeps data wrangling responsive for large data frames by offloading the work to the client. Software Depends: R (>= 4.1.0) Imports: cli, dplyr, glue, htmltools, jsonlite, promises, purrr, rlang, shiny, stringr Suggests: knitr, rmarkdown, shinytest2, testthat (>= 3.0.0) Maciej Banas <banasmaciek@gmail.com> Comprehensive R Archive Network (CRAN) Maciej Banas [cre, aut], Krystian Igras [aut] MIT + file LICENSE (https://CRAN.R-project.org/package=jsplyr/LICENSE) 2026-07-16 application/tgz https://CRAN.R-project.org/package=jsplyr doi:10.32614/CRAN.package.jsplyr
