OlevsoftUIKit
21 ES6 components, no framework, no build step, no dependencies. Every component is a plain class you instantiate, configure, and attach to the DOM — nothing renders on its own, nothing hides behind a virtual DOM or a compiler. It's the same library that runs the entire IMS interface.
No auto-rendering, no magic. Create an instance, chain configuration setters, append it to the page. Components talk to each other and to your code through emit/on events, not parent-child coupling.
new ui.Grid() — full class instances when you want direct control over lifecycle and state.
UIKit.grid() — a lighter factory-style API for quick composition.
Every component emits and listens for events instead of relying on parent-child references — swap a component out without rewiring everything around it.
Each one exists because a real screen in IMS needed it — not designed up front as a checklist.
The most complex component: sort, filter, inline editing and column resizing, all working off a separate filtered-rows array so the original data is never mutated.
Modal windows with a stack manager so nested dialogs always close in the right order.
A custom calendar overlay — built after the native date input conflicted with custom popups and needed two clicks to close.
Three different pickers for three different scales: native <select> past ~50 items, an autocomplete Combo up to ~200, a lightweight Dropdown below that.
Fields, validation and submit handling, with addField() appending a single field without re-rendering the whole form.
Fixed/stretch/fixed three-zone layouts using absolute positioning, a pattern carried over from an older widget library rather than flexbox.
Components read CSS custom properties, not hardcoded colors — a new visual theme is a new stylesheet with the same token names, no JS changes.
Questions, a trial request, anything — this opens your email client with the message pre-filled.
