Ndodhi lanshimi i dyt\u00eb i projektit Wasmer, q\u00eb zhvillon runtime p\u00ebr ekzekutimin e moduleve WebAssembly, i cili mund t\u00eb p\u00ebrdoret p\u00ebr t\u00eb krijuar aplikacione universale q\u00eb mund t\u00eb ekzekutohen n\u00eb sisteme t\u00eb ndryshme operative, si dhe p\u00ebr ekzekutimin izole t\u00eb kodit t\u00eb pasigurt.

P\u00ebr kompilimin n\u00eb WebAssembly mund t\u00eb p\u00ebrdoret mjeti Emscripten.

Menaxhimi i aksesit dhe nd\u00ebrveprimi me sistemin sigurohet p\u00ebrmes API WASI (WebAssembly System Interface), i cili ofron interface programimi p\u00ebr t\u00eb punuar me skedar\u00eb, soket\u00eb dhe funksione t\u00eb tjera t\u00eb ofruara nga sistemi operativ.

P\u00ebr t\u00eb ekzekutuar nj\u00eb kontejner WebAssembly, mjafton t\u00eb instaloni runtime-in Wasmer n\u00eb sistem, i cili ofrohet pa var\u00ebsi t\u00eb jashtme (\"curl https:\/\/get.wasmer.io -sSfL | sh\"), dhe t\u00eb ngarkoni skedarin e nevojsh\u00ebm (\"wasmer test.wasm\"). Programet shp\u00ebrndahen n\u00eb form\u00ebn e moduleve t\u00eb zakonshme WebAssembly, p\u00ebr menaxhimin e t\u00eb cilave mund t\u00eb p\u00ebrdoret menaxheri i paketeve WAPM. Wasmer \u00ebsht\u00eb gjithashtu i disponuesh\u00ebm si nj\u00eb bibliotek\u00eb, e cila mund t\u00eb p\u00ebrdoret p\u00ebr integrimin e kodit WebAssembly n\u00eb programe n\u00eb gjuh\u00ebt Rust, C\/C++, C#, D, Python, JavaScript, Go, PHP, Ruby, Elixir dhe Java. <\/p>\n

Platforma lejon arritjen e nj\u00eb performanc\u00eb t\u00eb ekzekutimit t\u00eb aplikacioneve, e cila \u00ebsht\u00eb e ngjashme me ekzekutimin e p\u00ebrmbledhjeve native.
