DESCRIPTION:The proliferation of client-side analytics and on-going vulnera
 bilities with shared code libraries have fueled the need for better safety
  standards for running executables from potentially unknown sources. WebAs
 sembly (WASM)\, a compilation target that allows lower-level languages lik
 e Rust\, C\, and Go to run in the browser or server-side at near-native sp
 eeds. Much like Docker changed the way we run virtualized workflows\, WASM
  runtimes create safe virtual environments where access to the host system
  is limited. \n\nIn combination with a new free and open source full-stack
  geospatial platform\, Matico\, efforts are underway to enable portability
  across workflows and applications to more easily use WASM modules. WASM i
 mplementations of GDAL are in the works\, and powerful open source Rust ge
 ospatial libraries are easily packaged for web usage through Wasm-Pack. Ad
 ditional geo WASM libraries like jsgeoda provide spatial indices\, binning
 \, and autocorrelation functions. Shareable code can be a recipe for secur
 ity vulnerabilities and attack vectors\, potentially exposing personal or 
 critical information\, particularly if there is the opportunity to run cod
 e server-side. WASM implementation alleviates this by requiring access fro
 m the Virtual Machine (VM) to be limited and explicit\, and for Javascript
  developers the lightweight AssemblyScript language is relatively familiar
 . \n\nAn upcoming Javascript feature called ShadowRealms may enable even s
 impler and more familiar implementations to safely run Javascript code sha
 red between module authors. These developments lay the groundwork for a hy
 brid front- and backend geospatial ecosystem of shareable code snippets an
 d analytic functions\, much like have emerged in the UI component Javascri
 pt ecosystem. The combination of emerging features positions web geospatia
 l analytics and This talk explores the implementation and performance of r
 unning geospatial analytic modules through a WebAssembly virtual machine a
 nd through the upcoming Javascript ShadowRealm specification.
