+ A Solid kit, built by a Go toolchain +

+ +

+ This layer is the original one: a Solid.js component kit — forms, tables, modals, menus, + tooltips, charts — that the applications shared before any of it was rewritten in Go. It is + still what those applications run. +

+

+ What is unusual is the build. There is no Node, no Vite, no Babel, and no{" "} + node_modules. + The TSX is compiled to Solid's runtime calls by a Go program, the CSS by a Go implementation + of Tailwind v4, and the whole thing is bundled by esbuild's Go API. The toolchain is a Go + package you import. +

+ +

The pipeline

+

+ One command builds this section. Every stage of it is Go: +

+ +
+ + + +
+ + + + + The single hardest invariant in this build is that there is exactly one copy of solid-js. Two + copies do not error — they render fine and then silently stop flushing effects, so onMount + never fires and nothing updates. kjol's vendor manifest is searched before the app's for + precisely this reason. + + +

What is on the other pages

+
+ + Components +

+ Buttons, badges, alerts, cards, tabs and menus — rendered live, not screenshotted. +

+ + + Forms +

+ Masked inputs, comboboxes, multi-select, toggles, and the validation helpers. +

+ + + AutoTable +

+ Sorting, search, column management, CSV export — from one array of column defs. +

AutoTable

+

+ One array of column definitions produces sorting, per-column search, column reordering by + drag, column show/hide, column resizing, pagination and CSV export. The page below writes no + table markup — only a rowRenderer{" "} + to say what a cell looks like. +

+ + + Sort by clicking a header. Drag a header to reorder. Use the toolbar to hide a column or + export what you are looking at. The column layout persists — it is keyed to localStorage, so + it survives a reload. + + +
+ ( + + ctx.setSearchValue("name", v)} + /> + ctx.setSearchValue("state", v)} + /> + + )} + rowRenderer={(item: Institution) => ( + <> + {item.name} + {item.state} + {item.term} + {item.rate.toFixed(2)}% + {money(item.minimum)} + + + + + )} + /> +
+ +
+

Local rows, or a server

+

+ This table is passed data. + Give it url instead and + the same column list drives a server-side query — the sort identifier becomes the sort key, + the search fields become query parameters, and pagination is handled for you. Nothing else + on the page changes. +

+

+ The Go/WASM layer has this same table, rewritten as Go returning a virtual DOM. Same + behaviour, no JavaScript — which is the whole argument the other half of this site is + making. +

Theming

+ +

+ No component in this kit names a colour. They say{" "} + bg-surface,{" "} + text-ink,{" "} + border-line — and + what those mean is decided in one place. That is the whole of the theme system, and it is why + dark mode is a rule that re-points ten variables rather than a{" "} + dark: variant on four hundred class strings. +

+ + +
+ +
+ currently {isDark() ? "dark" : "light"}, because + you asked for {mode()} +
+
+

+ Press it. Every component on every page of this section moves — none of them were told. + Your choice is remembered, and it is the same choice the Go/WASM section reads: + both halves of this site share one localStorage key, so the theme survives crossing between + two entirely different front-ends. +

+ + +

The contract

+

+ These are the tokens a component is allowed to name. Each swatch below is drawn with the token + itself, so this table is not a picture of the theme — it is the theme, and it repaints + when you press the switch. +

+ +
+ {TOKENS.map((t, i) => ( +
0 ? "border-t border-line" : "") + } + > + + {t.name} + {t.role} +
+ ))} +
+ + + The Go/WASM kit uses these exact token names. A designer changes{" "} + surface once and both halves of the site move together — even + though one is Solid compiled by esbuild and the other is Go compiled to WebAssembly. + + +

Where a variant is still needed

+

+ Two things a re-pointed token cannot fix, so they are the only places the kit still carries a{" "} + dark: variant. +

+ +
+ + Coloured tints +

+ A red-50 wash is invisible on a near-black surface. An + alert's tint has to become a deep, transparent one — a different colour, not a + different value of the same one. +

+ + + Fills that invert +

+ The neutral button is dark on a light page and light on a dark one — so its label must + invert with it. text-white would disappear the moment + the fill went pale. Hence three tokens, not one. +

+ +
+ + +
+ Neutral (inverts) + White (a surface) + Primary (a fill) + solid + fills stay put +
+ + + + The theme class is applied by a ten-line script in the document head, before the stylesheet and + before any markup. The server cannot read localStorage, so it cannot know which theme to send; + if the class waited for the bundle, every dark-mode reader would get a white page and then have + it snatched away. It is the only hand-written JavaScript on the Go/WASM side of this site. + + + + + +`} + /> +
