genX: front-end changes for humans

Business wants percentages shown with 2 decimals instead of 3? With traditional approaches, you're modifying database schemas, backend APIs, and frontend code - all fragile, all breaking things. Over and over again.

genx.software keeps display logic where it belongs: in the display layer. Your database stores raw numbers. Your backend passes them through. Your HTML template handles formatting (or any other purely front-end concern) with attributes like data-fmtx="decimal:2", data-accx="aria-label:{{statusText}} skip-if-empty", data-bindx="value:user.email validate:email".

One attribute change in your HTML template; the most robust part of your stack. No migrations, no backend deploys, no breakage. Just a few k of JavaScript reading your declarative intent and executing it at lightning speed.

Fully HATEOAS/DATAOS compliant.

🎭 cloak - No Format-on-Load Flash

genX serves raw values and formats them on the client, so for a frame or two the raw value can flash before it is rewritten (871580000000 → $871.58B). The opt-in cloak hides fx-format elements until genX formats them, and fails open: if genX never finishes, elements reveal their raw value rather than staying blank.

Opt-in, one line of config, and this whole page uses it:

window.genxConfig = {
  cloak: true,          // default false
  cloakTimeoutMs: 1500  // fail-open reveal if genX never finishes
};

Every formatted value above appeared already styled instead of flashing raw; that is the cloak at work.

Watch the difference

Replay a page load with the cloak on or off. With it off, the raw values flash red before formatting (FOUC). With it on, the space is reserved and only the finished value ever appears.

Live Interactive Demo - All Four Notations Working Together

Type in any of the inputs below to see how all four notation styles produce identical reactive behavior:

1. Verbose (Beginner)

Explicit attributes - most readable

Value: -

<input bx-model="polyDemo1"
       bx-debounce="500">

2. Compact (Expert)

Colon syntax - compact

Value: -

<input bx-model="polyDemo2:500">

3. JSON (Power User)

JSON configuration - flexible

Value: -

<input bx-model="polyDemo3"
       bx-opts='{"debounce":500}'>

💡 All three notations produce identical behavior:

500ms debounce delay after typing stops
Two-way reactive data binding
Automatic DOM synchronization
Same performance characteristics

Syntax Precedence (highest to lowest):

bx-debounce attribute (explicit)
bx-opts JSON configuration
bx-model="field:500" colon syntax

💡 All four notation styles produce identical behavior

Choose the style that best fits your workflow. genX supports all notations simultaneously in the same project.

Name	Age	Department	Hire Date	Salary
Alice Johnson	32	Engineering	2022-03-15	95000
Bob Smith	28	Marketing	2023-01-10	72000
Charlie Brown	45	Sales	2020-07-22	88000
Diana Prince	29	Engineering	2023-05-03	98000
Eve Martinez	38	HR	2021-11-18	76000
Frank Zhang	51	Engineering	2019-02-14	105000
Grace Lee	26	Design	2023-08-01	68000
Henry Wilson	42	Sales	2020-12-05	91000

<table tx-sortable>
  <thead>
    <tr>
      <th>Name</th>
      <th>Age</th>
      <th>Department</th>
      <th>Hire Date</th>
      <th>Salary</th>
    </tr>
  </thead>
  <tbody>
    <!-- Table rows -->
  </tbody>
</table>

2. Column-Level Sorting

Add sorting to specific columns one at a time with tx-sortable on individual headers.
