U publikua numri i tret\u00eb i r\u00ebnd\u00ebsish\u00ebm i projektit Wasmer, i cili zhvillon nj\u00eb 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 operative t\u00eb ndryshme, si dhe p\u00ebr ekzekutimin e izoluar t\u00eb kodit t\u00eb pabesuesh\u00ebm.

Programet paraqesin kontejner\u00eb t\u00eb leht\u00eb, n\u00eb t\u00eb cil\u00ebt ekzekutohet pseudokodi WebAssembly. K\u00ebta kontejner\u00eb nuk jan\u00eb t\u00eb lidhur me sistemin operativ dhe mund t\u00eb p\u00ebrmbajn\u00eb kod q\u00eb \u00ebsht\u00eb shkruar fillimisht n\u00eb \u00e7do gjuh\u00eb programimi. P\u00ebr p\u00ebrpunim n\u00eb WebAssembly mund t\u00eb p\u00ebrdoret mjet i quajtur Emscripten. P\u00ebr p\u00ebrkthimin e WebAssembly n\u00eb kodin makinerik t\u00eb platform\u00ebs aktuale, mb\u00ebshtetet lidhja e backend-eve t\u00eb ndryshme t\u00eb kompilimit (Singlepass, Cranelift, LLVM) dhe motor\u00ebve (p\u00ebrdorimi i JIT ose gjenerimi i kodit makinerik). <\/p>\n
Aplikacionet jan\u00eb t\u00eb izoluara nga sistemi kryesor n\u00eb nj\u00eb mjedis sandbox dhe kan\u00eb qasje vet\u00ebm n\u00eb funksionalitetin e deklaruar (mekanizmi i siguris\u00eb bazuar n\u00eb menaxhimin e mund\u00ebsive \u2014 p\u00ebr veprimet me \u00e7do burim (skedar\u00eb, katalog\u00eb, soket\u00eb, thirrje sistemore etj.), aplikacionit duhet t'i jepet autorizimi p\u00ebrkat\u00ebs). Menaxhimi i qasjes dhe nd\u00ebrveprimi me sistemin sigurohet p\u00ebrmes API WASI (WebAssembly System Interface), q\u00eb ofron interfisat programore p\u00ebr t\u00eb punuar me skedar\u00eb, soket\u00eb dhe funksione t\u00eb tjera q\u00eb ofrohen nga sistemi operativ. <\/p>\n
Platforma lejon arritjen e performanc\u00ebs s\u00eb ekzekutimit t\u00eb aplikacioneve, e cila \u00ebsht\u00eb e ngjashme me ekzekutimin e nd\u00ebrtim\u00ebve native.

P\u00ebr t\u00eb nisur kontejnerin WebAssembly, mjafton t\u00eb instaloni runtime-n Wasmer n\u00eb sistem, i cili ofrohet pa var\u00ebsi t\u00eb jashtme (\"curl https:\/\/get.wasmer.io -sSfL | sh\"), dhe t\u00eb nisni skedarin p\u00ebrkat\u00ebs (\"wasmer test.wasm\").

Ekipi i ri i «wasmer create-exe» \u00ebsht\u00eb rishikuar plot\u00ebsisht, duke lejuar transformimin e nj\u00eb skedari me kod t\u00eb nd\u00ebrmjet\u00ebm WebAssembly n\u00eb skedar\u00eb ekzekutiv\u00eb autonom\u00eb p\u00ebr platformat Linux, Windows dhe macOS, t\u00eb cil\u00ebt mund t\u00eb funksionojn\u00eb pa instaluar vet\u00eb Wasmer.\n
Ofrohet mund\u00ebsia e ekzekutimit t\u00eb pakove WAPM, t\u00eb vendosura n\u00eb katalogun wapm.io, p\u00ebrmes komand\u00ebs «wasmer run». P\u00ebr shembull, ekzekutimi i «wasmer run python\/python» do t\u00eb p\u00ebrfundoj\u00eb me ngarkimin nga repositor i wapm.io t\u00eb pakos python dhe ekzekutimin e saj.\n
API i Wasmer Rust \u00ebsht\u00eb rigsovuar komplet, me nj\u00eb stil t\u00eb ri t\u00eb pun\u00ebs me kujtes\u00ebn dhe mund\u00ebsin\u00eb p\u00ebr ruajtjen e sigurt t\u00eb objekteve Wasm n\u00eb struktur\u00ebn Store. \u00cbsht\u00eb propozuar nj\u00eb struktur\u00eb e re MemoryView q\u00eb lejon t\u00eb lexoni dhe shkruani t\u00eb dh\u00ebna n\u00eb nj\u00eb zon\u00eb lineare t\u00eb kujtes\u00ebs.\n
