DevSexy code customs · every attribute declared

Markup crosses a prop boundary.

HTML and SVG can both resemble JSX. Their attributes, style values, namespaces, events, and wrapper contracts still need different inspections before React owns them.

HTML lane

<label class="field" for="email">
  • DOM property names
  • void elements
  • form associations

SVG lane

<path stroke-width="2" fill-rule="evenodd">
  • camel-cased paint props
  • ID and URL references
  • ARIA stays hyphenated

Behavior requires a real function

Inline style object lab

A CSS declaration string becomes JavaScript data.

HTML attribute
style="font-size: 14px; --brand: #bfd456; line-height: 1.4"
React style prop
style={{ fontSize: "14px", "--brand": "#bfd456", lineHeight: "1.4" }}
font-sizefontSizecamelCase key
--brand"--brand"custom property stays quoted
14px"14px"unit remains explicit
1.4"1.4"converter does not guess numeric intent

Event-handler quarantine

Behavior-bearing strings do not become trusted functions.

HTML event attributes execute in a global-string scope. React expects a function reference with application state and imports. The Worker preserves the evidence under a data-devsexy-review-* name and never runs it.

Incoming behavior string
<button &#111;nclick="checkout(cart)">Buy</button>
Quarantined evidence
<button data-devsexy-review-onclick="checkout(cart)">Buy</button>

Replace after review: &#111;nClick={() => checkout(cart)}

Wrapper contract

Choose output ownership, not just an extension.

Fragment

<>…</>

Groups one or many roots without adding a DOM node.

JSX component

export function Badge()

JavaScript syntax; props remain your design decision.

TSX component

(): React.JSX.Element

Adds a return contract, not invented prop types.

Component name

Uppercase identifier

React treats lowercase names as built-in elements.

Post-conversion compiler gate

Converted is the beginning of integration.

01

Parse JSX / TSX

The output must compile under the target toolchain.

02

Read the receipt

Review quarantined handlers and unknown attributes.

03

Render the asset

Check labels, IDs, gradients, masks, and form associations.

04

Add behavior and types

Connect real functions, state, props, and domain types.

05

Lint and test

React warnings and interaction tests own the final verdict.
