WildflowerJS debuted strongly on the official Krausest js-framework-benchmark with the Chrome 152 run released September 1, 2026. The results below were all run on the maintainer's hardware.

02 · New Feature
Queries write back
Since 1.3, a query declares where data comes from and keeps it fresh. In 1.5 it declares where data goes. Add to: and the same query sends changes. They land on screen immediately, the server confirms them, and a rejection rolls them back field-by-field.
The write surface is one method
write(item) is the entire write surface. The row updates before the request leaves, isStale reports until the server confirms, and a rejection reverts only the fields the failed write still owns, so overlapping edits fail independently.
A returned record applies as server truth. A temporary id corrects in place with no flicker. Loading flags, races, and rollback bookkeeping are the framework's problem now.
wildflower.query('tasks', {
from: '/api/tasks',
key: 'id',
to: '/api/tasks/:id', // where write() sends changes
body: item => item, // what to send
confirmation: data => data // the reply applies as server truth
});
// in a component action:
this.$tasks.write({ id: 7, done: true });
// on screen now, rolled back if the server says noLive, against a simulated server with 400 ms latency. Flip the rejection switch and watch a write roll itself back.

Computeds go async
A computed property may now return a promise. Same computed: block, same data-bind, same dependency tracking. Bindings keep the last settled value while a new one is in flight and update when it lands.
computed: {
async user() {
const r = await fetch('/api/users/' + this.userId);
return r.json();
}
}
// <h1 data-bind="user.name"></h1> and that's itNo new syntax to learn
Change a dependency and the request relaunches. A superseded request is discarded whole, so a slow response never overwrites a fast one. Errors route to the component's onError like any other computed failure.
Live. Pick the slow profile, then the fast one before it lands: the late response is discarded and the card never goes backwards.

mini-pool: the games build
Entity pools are WildflowerJS's per-frame rendering primitive, built for simulations, games, and visualizations with thousands of moving entities. The new mini-pool tier ships pools without the list cluster: 55 KB compressed, the whole framework underneath.
