    Measuring the Cost of a GraphQL Query

    Developers often make the mistake of centralizing fragment definitions and using them in every query, even when only a subset of attributes is needed. It’s important for GraphQL clients to be mindful of query optimization because the server has to process the client’s query and generate a customized response. If the client’s query isn’t optimized, it can force the server to process unnecessary data, resulting in slower response times. Unfortunately, identifying performance bottlenecks and slow queries, especially in an Apollo Federation architecture, can be quite challenging. In this session, we’ll dive into the reasons why measuring the “cost” of a GraphQL query is not a simple task. We’ll explore how the unique design of GraphQL affects the speed at which it executes a query. You’ll understand why it’s essential for you, as a client, to prioritize query optimization in order to achieve faster and more efficient performance.

      Untold CQRS

      Tutti siamo abituati a produrre o consumare API RESTful, attraverso metodi CRUD, ma siamo sicuri che sia sempre il modo migliore per far interagire il client con il server? In questo talk analizzeremo i vantaggi dell’approccio CQRS (e del pattern da cui deriva, CQS) evidenziando le differenze rispetto al classico paradigma CRUD.

      La rivoluzione dei framework front-end

      Stiamo assistendo ad una rivoluzione del mondo front-end e moltissimi nuovi framework (full-stack) stanno nascendo o si stanno evolvendo: Next e i React Server Component, Astro, Qwik, SvelteKit, SolidJS, solo per citarne alcuni. L’ottimizzazione per i motori di ricerca e l’incremento le prestazioni sono i principali motivi che stanno spingendo il mondo JavaScript ad abbandonare il Client Side Rendering (utilizzato principalmente nelle SPA) e tornare al Server Side Rendering (SSR), alla Static Generation (SSG) e ad adottare molteplici nuove strategie per migliorare il processo di Hydration, al fine di aumentare i punteggi dei Core Web Vitals e la velocità di rendering. SEO, User Experience , incremento delle conversioni e minor impatto ambientale sono le motivazioni principali che spingono i vari team ad andare in questa direzione. Cosa dobbiamo aspettarci per il prossimo futuro? E come è possibile raggiungere certi obiettivi e aggirare dei limiti che finora non permettevano di raggiungere certi risultati? In questa sessione interattiva, Fabio farà una panoramica sull’argomento e farà partecipare attivamente il pubblico con domande e quiz: i più preparati sul tema avranno la possibilità di vincere gadget, libri e licenze software : )
