I'm doing an audit in a large codebase, and I need to search to find all uses of a component where it is used with a given prop. I'm thinking a regex could be useful here, but I can't figure out how to handle potential newlines in the markup. I need to be able to differentiate between these two usages, finding the latter:
<Component
prop1="value1"
prop2={2}
/>
<Component
prop1="value1"
targetProp={3}
prop2={2}
/>
I don't care about the value of the target prop, just that it exists on the component.

JSX allows us to write HTML elements in JavaScript and place them in the DOM without any createElement() and/or appendChild() methods. JSX converts HTML tags into react elements. You are not required to use JSX, but JSX makes it easier to write React applications.
You want to use JSX inside your props You can simply use {} to cause JSX to parse the parameter. The only limitation is the same as for every JSX element: It must return only one root element.
Embedding Expressions in JSXYou can put any valid JavaScript expression inside the curly braces in JSX. For example, 2 + 2 , user.firstName , or formatName(user) are all valid JavaScript expressions. In the example below, we embed the result of calling a JavaScript function, formatName(user) , into an <h1> element.
It is an object with type , props and key . JSX. Element is ReactElement , whose props and type have type any , so they are more or less the same. const jsx = <div>hello</div> const ele = React.
<Component(\s|\n)[^>]*?propertyThis one support line break.
