React este o bibliotecă JavaScript pentru construirea de interfețe utilizator din componente încapsulate și reutilizabile. Acesta randează vederile declarativ, actualizând automat doar părțile interfeței care se modifică atunci când datele subiacente se schimbă, lăsând în același timp secțiunile stabile intacte. Motorul său de randare împarte munca în unități incrementale, prioritizate, care pot fi întrerupte, reluate sau anulate fără a bloca thread-ul principal. Un algoritm de diffing calculează modificările minime între arborii UI stabiliți, iar logica de randare de bază rămâne decuplată de orice țintă de output specifică. Logica de stare și efectele secundare se atașează componentelor funcționale printr-un mecanism de ordine a apelurilor, permițând comportamentului reutilizabil să se compună cu fluxuri de date previzibile de la părinte la copil. Același model de componente vizează browserele web, mediile de server prin Node și platformele mobile native, astfel încât codul interfeței să poată fi utilizat în diverse contexte fără a rescrie logica de bază. Streaming-ul pe partea de server generează HTML incremental pentru încărcări inițiale mai rapide ale paginii, cu hidratare progresivă care leagă interactivitatea odată ce pagina ajunge în browser.

React este o bibliotecă JavaScript pentru construirea de interfețe utilizator bazată pe o arhitectură orientată pe componente și flux de date unidirecțional.

Vue este un framework JavaScript progresiv, bazat pe componente, conceput pentru construirea de interfețe utilizator reactive și aplicații single-page. Se concentrează pe un sistem de template-uri declarativ care transformă HTML-ul în funcții de randare eficiente, permițând dezvoltatorilor să organizeze interfețe complexe în unități izolate, reutilizabile, care se sincronizează automat cu starea aplicației. Framework-ul se distinge printr-un sistem de reactivitate bazat pe urmărirea dependențelor care monitorizează accesul la date în timpul randării pentru a declanșa actualizări precise. Oferă o arhitectură flexibilă care suportă atât adoptarea incrementală ca bibliotecă ușoară, cât și dezvoltarea de aplicații la scară largă. Dezvoltatorii pot utiliza un model de extensibilitate robust, bazat pe plugin-uri, pentru a injecta logică globală, în timp ce reconcilierea virtuală a DOM-ului framework-ului asigură actualizări eficiente ale interfeței prin calcularea mutațiilor minime. Dincolo de capabilitățile sale de randare de bază, proiectul include o suită cuprinzătoare de instrumente pentru gestionarea stării aplicației, rutarea bazată pe URL și randarea pe partea de server. Oferă suport extins pentru compunerea componentelor, distribuția conținutului și gestionarea animațiilor, alături de măsuri de securitate încorporate, cum ar fi escaparea automată a conținutului pentru a preveni vulnerabilitățile comune. Framework-ul este distribuit cu declarații oficiale de tip pentru a susține analiza statică și poate fi instalat prin manageri de pachete standard sau integrat direct în mediile de browser prin tag-uri script.
