We’re introducing a new approach for working with feature flags. This approach allows declaring feature flags in code and calling them as functions. Flags implemented using this pattern can automatically respect overrides set by the Vercel Toolbar, and integrate with our Developer Experience Platform features like Web Analytics and Runtime Logs.The pattern avoids common pitfalls of client-side feature flag and experimentation usage, such as flashing the wrong experiment, loading spinners, layout shift, and jank. It works with any feature flag provider and even custom setups.The pattern further allows for optionally precomputing certain feature flags in Middleware. Middleware can then route visitors to statically generated pages tailored to their specific combination of feature flags and experiments.This even works when multiple flags are present on the page, which typically suffers from combinatory explosion. Precomputing is great for experimentation on marketing pages as it allows kee

Web page load times and responsiveness to user action in web apps is a primary driver of user satisfaction–and both are often dominated by network latency.Latency itself is a function of the user's connection to the internet (Wifi, LTE, 5G), how far away the server is that the user is connecting to, and the quality of the network in between.While the latency numbers may seem low by themselves, they compound quickly. For example, a of depth 3 on a 300ms link leads to a total latency of 900ms. Technologies like can move network waterfalls to the server where the same request pattern might be 100 times as fast.network waterfallReact Server ComponentsRead more
