Adds data-component-trace attribute to html elements showing the trace of React components names that led to this element creation.

Note: it will only work with JSX elements, not with React.createElement. If you're using TypeScript and transpile it separately, use "jsx": "preserve" in your tsconfig.json and add preset-react to your babel presets.

Useful when combined with component-trace-element-finder

Considering components structure:

const HeaderOfComponent = () => <h1 />;
const ContentOfComponent = () => <div />;
const SecondComponent = () => <><HeaderOfComponent /><ContentOfComponent /></>;
const Component = () => <SecondComponent />;
render(<Component />);

Resulting HTML markup will look like this:

<h1 data-component-trace=" component second-component header-of-component"></h1>
<div data-component-trace=" component second-component content-of-component"></div>

where components names are separated by a single space

• attribute - any attribute name you want, should begin from data-. Default: data-component-trace.
• format - can be "camel" (camelCase), "snake" (snake_case) or "kebab" (kebab-case). Default: kebab.
• separator - can by any non-empty string. Default: (single space, useful for selectors like [data-component-trace~=second-component]).

Example:

 ["react-component-trace-data-attr", {
 "attribute": "data-component-trace",
 "format": "kebab",
 "separator": " ",
 }]
