solid-highlight-words

Solid component to highlight words within a larger body of text. Based on react-highlight-words

Check out a demo here.

Usage

Install it:

npm i solid-highlight-words
# or
yarn add solid-highlight-words
# or
pnpm add solid-highlight-words

To use it, just provide it with an array of search terms and a body of text to highlight.

Try this example in Code Sandbox.

import { createRoot } from "solid-js";
import { Highlighter } from "solid-highlight-words";

const root = createRoot(document.getElementById("root"));
root.render(
  <Highlighter
    highlightClass="YourHighlightClass"
    searchWords={["and", "or", "the"]}
    autoEscape={true}
    textToHighlight="The dog is chasing the cat. Or perhaps they're just playing?"
  />
);

And the Highlighter will mark all occurrences of search terms within the text:

Props

| Property | Type | Required? | Description | | ------------------ | --------------------------- | :-------: | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | activeClass | String | | The class name to be applied to an active match. Use along with activeIdx | | activeIdx | Number | | Specify the match index that should be actively highlighted. Use along with activeClass | | activeStyle | Object | | The inline style to be applied to an active match. Use along with activeIdx | | autoEscape | Boolean | | Escape characters in searchWords which are meaningful in regular expressions | | class | String | | CSS class name applied to the outer/wrapper <span> | | caseSensitive | Boolean | | Search should be case sensitive; defaults to false | | findChunks | Function | | Use a custom function to search for matching chunks. This makes it possible to use arbitrary logic when looking for matches. See the default findChunks function in highlight-words-core for signature. Have a look at the custom findChunks example on how to use it. | | highlightClass | String or Object | | CSS class name applied to highlighted text or object mapping search term matches to class names. | | highlightStyle | Object | | Inline styles applied to highlighted text | | highlightTag | Node or String | | Type of tag to wrap around highlighted matches. Defaults to mark but can also be a Solid ValidComponent | | sanitize | Function | | Process each search word and text to highlight before comparing (eg remove accents); signature (text: string): string | | searchWords | Array<String | RegExp> | ✓ | Array of search words. String search terms are automatically cast to RegExps unless autoEscape is true. | | textToHighlight | String | ✓ | Text to highlight matches in | | unhighlightClass | String | | CSS class name applied to unhighlighted text | | unhighlightStyle | Object | | Inline styles applied to unhighlighted text | | unhighlightTag | Node or String | | Type of tag applied to unhighlighted parts. Defaults to span but can also be a Solid ValidComponent | | * | any | | Any other props (such as title or data-*) are applied to the outer/wrapper <span> |

Custom highlight tag

By default, this component uses an HTML Mark Text element (<mark>) to wrap matched text, but you can inject a custom tag using the highlightTag property. This tag should be a Solid ValidComponent that accepts the following properties:

| Property | Type | Description | | -------------- | ------ | ---------------------- | | children | String | Text to be highlighted | | highlightIdx | Number | Index of matched text |

For example:

const Highlight = ({ children, highlightIdx }) => (
  <strong class="highlighted-text">{children}</strong>
);
