unreliable environments react summit 2026 34 min architecting reliable react systems in unreliable environments rajni gediya mentorship available hinge health welcome to react summit 2026 discussing architecting reliable react systems in unreliable environments real world challenges with async complexity state management and app flow impact addressing issues with unreliable connections api failures and lack of ui system sync managing ota updates boolean soup problem and useeffect dependency chaos in state management dealing with ui state discrepancies hidden updates and inconsistencies ensuring deterministic system architecture for accurate ui feedback and optimizing state management with clear boundaries and a state machine architecture streaming systems hidden risks and ai driven consequences ai coding summit london 27 min streaming systems hidden risks and ai driven consequences olena kutsenko confluent the talk covers various aspects of deception and security in ai and data systems it discusses the historical use of misinformation during world war ii to influence decision making ai model poisoning through malicious data input and the challenges of ensuring data integrity in real time pipelines are highlighted the importance of peripheral information attacks data contracts stream governance and anomaly detection in maintaining ai system security is emphasized strategies for protecting data integrity detecting anomalies and choosing appropriate ai models are also discussed security modernizing your react app compiler useeffectevent activity friends react summit 2026 27 min modernizing your react app compiler useeffectevent activity friends vitor alencar chilipiper victor shares experiences inheriting codebase and explains the importance of react s updates for code cleanliness agenda includes react evolution api usage modernization playbook and insightful discussions react 19 impact on react s evolution towards a declarative model for state management and form handling react s shift towards a declarative model impacting form handling and state management with react 19 updates including new apis and the importance of the react compiler for efficient development using react compiler for efficient development and code simplification measuring code base changes with memorization hooks identification introducing user fact event api for dependency free code handling state persistence challenges with the activity api for seamless user experiences and resource management utilizing the activity api for precise state management and resource optimization in react native applications exploring powerful user cases tabs example pre rendering and back navigation benefits with the activity api exploring the value of instant experiences with back navigation and code optimization through api adoption measuring success avoiding ai dependence and understanding the importance of learning for effective development addressing challenges post ai era emphasizing responsibility in learning maintaining control and ensuring security practical steps include using react compiler auditing code for activity api integration and optimizing data flow for enhanced user experience react supercharging your tooling with rust jsnation 2026 24 min supercharging your tooling with rust maël nison lead maintainer of yarn mael from

taking a dump using heap dumps to find and fix nodejs memory and cpu problems dan shappir snyk dan shapir introduces heap dumps to identify and fix node js memory and cpu issues memory leaks in javascript occur when objects are still reachable impacting memory usage continuous memory rise from leaks can deplete memory and lead to cpu usage escalation detecting and resolving memory leaks promptly is crucial to prevent system unresponsiveness in production environments heap dumps and memory dumps help analyze memory issues with chrome devtools aiding in finding memory leaks pinpointing memory leaks involves comparing heap snapshots and analyzing leaked objects alternative methods for generating heap snapshots include new experimental node flags automatic triggers and built in apis

content dominik dorfmeister react query maintainer react query is a popular library with significant weekly downloads and positive user sentiment it may have trade offs like bundle size but the actual size shipped is smaller bundle size optimization can be achieved by exporting only necessary features react query s declarative approach eliminates the need for custom data fetching solutions it offers caching request duplication background updates and more rackquery doesn t support normalized caching but refetching after invalidation works fine react s vision includes suspense architecture and server components the documentation could be improved with a more structured flow tensorstack query can be a good choice for next js apps but not necessary with mature frameworks the 10 stack
