How it works

The component is based on a ‘content editable’ div that replicates the behavior of an input tag.

As the user inputs content, the component evaluates the div’s text and analyzes it using regular expressions (regex).

Any fragment that matches the regex is encapsulated within an HTML tag, with the default being <strong> (or as specified) for which the relevant styles are then applied.

Use Cases

Use cases example :

  • Highlight search operators (example : and, or, not, “) inside a search bar

  • Highlight id like entries (ex: company number, salesforce id, random code)

  • Highlight business specific keyword

    • Protocols : http/https

    • Language syntax : select, from, where

    • Auth methods : Basic, Bearer


List of component props :
