        <h1>LaraGrid — an Excel-style, keyboard-first datagrid for Laravel&nbsp;+&nbsp;Livewire</h1>

        <p class="lede">
            LaraGrid is a <strong>Laravel datagrid package</strong> extracted from a production
            accounting system built for spreadsheet-trained operators, then made app-neutral.
            The engine is framework-free vanilla JavaScript that owns every cell it paints: the
            grid body lives inside a <code>wire:ignore</code> region, Livewire never morphs a
            row, and all server traffic runs over renderless RPCs. The result is
            spreadsheet-grade speed with Laravel-grade authority — every edit is validated,
            authorized and recomputed server-side.
        </p>

        <p class="lede">
            Everything is configured <strong>in your component class with chained methods</strong>.
            No Blade wiring, no JavaScript to write, no npm step —
            <code>composer require</code> is the entire install.
        </p>

        <pre class="snippet"><code>composer require {{ Seo::PACKAGE }}</code></pre>

        <p class="muted">
            PHP 8.1+ · Laravel 10 / 11 / 12 / 13 · Livewire 4.1+ (installed automatically) ·

    <h2>What a Laravel datagrid should do out of the box</h2>

    <div class="cards">
        <article>
            <h3>Server-side sorting, search &amp; filters</h3>
            <p>Declare <code>searchable()</code>, <code>filters()</code> and
               <code>sortable()</code> and the toolbar renders itself. Every narrowing runs
               through a whitelisted, bound-parameter SQL pipeline that is fail-closed by
               construction — nothing the browser sends can widen the query.</p>
        </article>
        <article>
            <h3>Pagination that adapts</h3>
            <p><code>paginate()</code> with a per-page picker, plus
               <code>singlePageUpTo(N)</code>: whenever the filtered set fits, the grid serves
               it whole and drops the pager. Oversized first pages defer to a post-boot fetch,
               so mount HTML stays small at any table size.</p>
        </article>
        <article>
            <h3>CSV, Excel and PDF export</h3>
            <p><code>exportable()</code> downloads the operator's current view — active sort,
               search and filters over the whole filtered set. All three writers are
               dependency-free: BOM-ed UTF-8 CSV, native SpreadsheetML XLSX with typed number
               cells, and a native A4 PDF writer. Register your own for anything else.</p>
        </article>
        <article>
            <h3>Per-user saved views</h3>
            <p><code>savedViews()</code> persists named snapshots of search + filters + sort +
               per-page + column layout, server-side and scoped to the authenticated operator.
               Views are sanitized against the grid's declared surface, so one operator can
               never see, apply or delete another's.</p>
        </article>
        <article>
            <h3>Inline editing with a real contract</h3>
            <p>The client paints every keystroke and streams typed ops; the server authorizes,
               casts, validates, runs your hooks and recomputes formulas, then reconciles the
               authoritative values back. Rows are addressed by stable keys, never positions.</p>
        </article>
        <article>
            <h3>Formula columns in two runtimes</h3>
            <p><code>FormulaColumn::make('amount')-&gt;formula('round(qty * rate, 2)')</code> —
               evaluated live in the browser for instant feedback and authoritatively in PHP by
               a twin evaluator, pinned to the same committed vectors.</p>
        </article>
        <article>
            <h3>Async pickers that enrich the row</h3>
            <p><code>SearchSelectColumn</code> streams options over an RPC and
               <code>onSelect()</code> pre-fills dependent cells server-side; formula columns
               recompute after the hook, so one pick updates the whole row in a single round
               trip.</p>
        </article>
        <article>
            <h3>Undo, redo and bulk paste</h3>
            <p>100 steps of history where one gesture is one step — a 200-cell paste, a
               fill-down, a row delete. Undo replays through the same op protocol as typing, so
               it can never resurrect a value your rules would refuse.</p>
        </article>
        <article>
            <h3>Actions, fail-closed end to end</h3>
            <p>Row, bulk and toolbar actions. The client echoes only an action name; the server
               re-authorizes the grid gate and the action gate, re-resolves the row from its
               authoritative source, and re-checks <code>visible()</code> before your closure
               runs.</p>
        </article>
        <article>
            <h3>Theming with CSS tokens</h3>
            <p>Six shipped schemes with coordinated dark variants, three densities, and every
               visual exposed as a <code>--lgrid-*</code> custom property with a self-contained
               default. In a Tailwind v4 app it adopts your <code>@theme</code> palette
               automatically.</p>
        </article>
        <article>
            <h3>Accessible by construction</h3>
            <p>The grid is one tab stop with a roving active cell exposed through
               <code>aria-activedescendant</code>, a polite live-region announcer for
               selection and clipboard changes, and no per-cell tabindex to trap anyone.</p>
        </article>
        <article>
            <h3>Extensible without forking</h3>
            <p>Custom column types, painters, editors, formatters and parse kinds register
               through PHP registries and their <code>window.LaraGrid</code> twins. The
               renderer never learns your types — it asks the registry.</p>
        </article>

    <h2>The keyboard, which is the point</h2>
    <p class="lede">
        Two presets, one switch: <code>keymap('entry')</code> — the serpentine data-entry
        rhythm Tally and Busy trained a generation of operators on — or
        <code>keymap('excel')</code>, where Enter moves down and Tab moves right and nothing
        ever blocks.
