[DotJs2025] Love/Hate: Upgrading to Web2.5 with Local-First
The web’s saga brims with schisms—web versus native, TypeScript versus vanilla—each spawning silos where synergy beckons. Kyle Simpson, a human-centric technologist and getify’s architect, bridged these chasms at dotJS 2025, advocating “Web2.5”: a local-first ethos reclaiming autonomy from cloud colossi. Acclaimed for “You Don’t Know JS” and a million course views, Kyle chronicled divides’ deceit, positing device-centric data as the salve for privacy’s plight and ownership’s erosion.
Kyle’s parable evoked binaries’ burden: HTML/CSS zealots scorning JS behemoths, frontend sentinels eyeing backend warily. False forks abound—privacy or ease? Security or swiftness? Ownership or SaaS servitude? Web2’s vendor vassalage—Apple/Google hoarding silos—exacts tribute: data’s ransom, identity’s lease. Local-first inverts: custody on-device, apps as data weavers, CRDTs (conflict-free replicated data types) syncing sans servers. Kyle’s trinity: user sovereign identity (DID—decentralized identifiers), data dominion (P2P meshes like IPFS), app perpetuity (long-now principle: timeless access).
Ink & Switch’s manifesto inspired: seven tenets—privacy by design, gradual sync, offline primacy—Kyle adapted for Web2.5. ElectricSQL’s Postgres mirror, Triplit’s reactive stores—tools transmuting apps into autonomous agents. No zero-sum: convenience persists via selective shares, resilience through federated backups. Kyle’s mea culpa: complicit in Web2’s centralization, now atonement via getify’s culture forge, championing minimalism’s maxim.
This ascent demands audacity: query complicity in data’s despoliation, erect bridges via local-first. Web2.5 beckons—a participatory paradigm where users, not platforms, preside.
Divides’ Deception and Bridges’ Blueprint
Kyle cataloged rifts: frameworks’ feuds, stacks’ schisms—each zero-sum sophistry. Local-first liberates: DIDs for self-sovereign selves, CRDTs for seamless merges, eschewing extractive empires. Ink & Switch’s axioms—user control, smooth sync—Kyle reframed for web’s wilderness.
Pillars of Possession
Autonomy’s arch: device-held data, P2P propagation—ElectricSQL’s replicas, Triplit’s reactivity. Longevity’s lore: apps eternal, subscriptions supplanted. Kyle’s query: perpetuate Web2’s plunder or pioneer Web2.5’s plenty?

[DotJs2025] Using AI with JavaScript: Good Idea?
Amid the AI deluge reshaping codecraft, a tantalizing prospect emerges: harnessing neural nets natively in JavaScript, sidestepping Python’s quagmires or API tolls. Wes Bos, a prolific Canadian educator whose Syntax.fm podcast and courses have schooled half a million in JS mastery, probed this frontier at dotJS 2025. Renowned for demystifying ES6 and React, Wes extolled browser-bound inference via Transformers.js, weighing its virtues—privacy’s fortress, latency’s lightning—against hardware’s hurdles, affirming JS’s prowess for sundry smart apps.
Wes’s overture skewered the status quo: cloud fetches or Python purgatory, both anathema to JS purists. His heresy: embed LLMs client-side, ONNX Runtime fueling Hugging Face’s arsenal—sentiment sifters, translation tomes, even Stable Diffusion’s slimmer kin. Transformers.js’s pipeline paradigm gleams: import, instantiate (pipeline('sentiment-analysis')), infer (result = await pipe(input)). Wes demoed a local scribe: prompt yields prose, all sans servers, WebGPU accelerating where GPUs oblige. Onyx.js, his bespoke wrapper, streamlines: model loads, GPU probes, inferences ignite—be it code completion or image captioning.
Trade-offs tempered triumph. Footprints fluctuate: 2MB wisps to 2GB behemoths, browser quotas (Safari’s 2GB cap) constraining colossi. Compute cedes to client: beefy rigs revel, mobiles murmur—Wes likened Roblox’s drain to LLM’s voracity. Yet, upsides dazzle: zero egress fees, data’s domicile (GDPR’s grace), offline oases. 2025’s tide—Chrome’s stable WebNN, Firefox’s flag—heralds ubiquity, Wes forecasting six-month Safari stability. His verdict: JS, with its ubiquity and ecosystem, carves niches where immediacy reigns—chatbots, AR filters—not every oracle, but myriad muses.
Wes’s zeal stemmed personal: from receipt printers to microcontroller React, JS’s whimsy fuels folly. Transformers.js empowers prototypes unbound—anime avatars, code clairvoyants—inviting creators to conjure without concessions.
Client-Side Sorcery Unveiled
Wes unpacked pipelines: sentiment sorters, summarizers—Hugging Face’s trove, ONNX-optimized. Onyx’s facade: await onnx.loadModel('gpt2'), GPU fallback, inferences instantaneous. WebGPU’s dawn (Chrome 2025 stable) unlocks acceleration, privacy paramount—no telemetry trails.
Balancing Bytes and Burdens
Models’ mass mandates moderation: slim variants suffice for mobile, diffusion downsized. Battery’s bite, CPU’s churn—Wes warned of Roblox parallels—yet offline allure and cost calculus compel. JS’s sinew: ecosystem’s expanse, browser’s bastion, birthing bespoke brains.

[DotJs2025] Node.js Will Use All the Memory Available, and That’s OK!
In the pulsating heart of server-side JavaScript, where applications hum under relentless loads, a persistent myth endures: Node.js’s voracious appetite for RAM signals impending doom. Matteo Collina, co-founder and CTO at Platformatic, dismantled this notion at dotJS 2025, revealing how V8’s sophisticated heap stewardship—far from a liability—empowers resilient, high-throughput services. With over 15 years sculpting performant ecosystems, including Fastify’s lean framework and Pino’s swift logging, Matteo illuminated the elegance of embracing memory as a strategic asset, not an adversary. His revelation: judicious tuning transforms perceived excess into a catalyst for latency gains and stability, urging developers to recalibrate preconceptions for enterprise-grade robustness.
Matteo commenced with a ritual lament: weekly pleas from harried coders convinced their apps hemorrhage resources, only to confess manual terminations at arbitrary thresholds—no crashes, merely preempted panics. This vignette unveiled the crux: Node’s default 1.4GB cap (64-bit) isn’t a leak’s harbinger but a deliberate throttle, safeguarding against unchecked sprawl. True leaks—orphaned closures, eternal event emitters—defy GC’s mercy, accruing via retain cycles. Yet, most “leaks” masquerade as legitimate growth: caches bloating under traffic, buffers queuing async floods. Matteo advocated profiling primacy: Chrome DevTools’ heap snapshots, clinic.js’s flame charts—tools unmasking culprits sans conjecture.
Delving into V8’s bowels, Matteo traced the Orinoco collector’s cadence: minor sweeps scavenging new-space detritus, majors consolidating old-space survivors. Latency lurks in these pauses; unchecked heaps amplify them, stalling event loops. His panacea: hoist the ceiling via --max-old-space-size=4096, bartering RAM for elongated intervals between majors. Benchmarks corroborated: a 4GB tweak on a Fastify benchmark slashed P99 latency by 8-10%, throughput surging analogously—thinner GC curves yielding smoother sails. This alchemy, Matteo posited, flips economics: memory’s abundance (cloud’s elastic reservoirs) trumps compute’s scarcity, especially as SSDs eclipse HDDs in I/O velocity.
Enterprise vignettes abounded. Platformatic’s observability suite, Pino’s zero-allocation streams—testaments to lean design—thrive sans austerity. Matteo cautioned: leaks persist, demanding vigilance—nullify globals, prune listeners, wield weak maps for caches. Yet, fear not the fullness; it’s V8’s vote of confidence in your workload’s vitality. As Kubernetes autoscalers and monitoring recipes (his forthcoming tome’s bounty) democratize, Node’s memory ethos evolves from taboo to triumph.
Demystifying Heaps and Collectors
Matteo dissected V8’s realms: new-space for ephemeral allocations, old-space for tenured stalwarts—Orinoco’s incremental majors mitigating stalls. Defaults constrain; elevations liberate, as 2025’s guides affirm: monitor via --inspect, profile with heapdump.js, tuning for 10% latency dividends sans leaks.
Trading Bytes for Bandwidth
Empirical edges: Fastify’s trials evince heap hikes yielding throughput boons, GC pauses pruned. Platformatic’s ethos—frictionless backends—embodies this: Pino’s streams, Fastify’s routers, all memory-savvy. Matteo’s gift: enterprise blueprints, from K8s scaling to on-prem Next.js, in his 296-page manifesto.
