Create Social Proof Badges, Banners & Testimonials Generate social proof HTML elements — badges, banners, counters, and testimonial blocks.

Under the hood, it utilizes React for building the user interface and managing state changes through hooks like useState. When a user selects a style or inputs metric, value, or context data, this information is stored in state variables and then used to populate templates defined as JavaScript objects. These templates contain HTML strings with inline styles and placeholders for dynamic values, which are replaced using template literals. For example, the badge template uses an SVG icon from the React component library, while the testimonial template wraps quote text in a paragraph element with italic styling.

The tool's core functionality relies on browser APIs like the clipboard API, specifically the copyToClipboard function from the utils library, to enable users to easily copy generated HTML code. This code is stored as a string in the html variable and updated whenever state changes occur. When the user clicks the Copy HTML button, it triggers an async function that attempts to write this HTML string to the system clipboard using the navigator.clipboard.writeText method. The tool also uses TypeScript for type checking and ensures compatibility with various browsers by employing established web development practices like using system-ui font family for maximum legibility across devices.

In terms of data structures, the templates object is a key-value map where each key corresponds to a specific style (badge, banner, counter, or testimonial) and its associated value is an HTML string template. This allows for efficient lookup and rendering of the selected template based on user input. The use of CSS styles like display inline-flex, gap, padding, border-radius, and background colors enables the creation of visually appealing trust signal elements that can be easily customized through the tool's interface. Overall, it combines React's component-based architecture with JavaScript's templating capabilities and browser APIs to generate customizable social proof HTML elements.
