Topsort’s banner.js public library allows marketplaces display banner ads through a low-code integration. By using a simple HTML tag, the marketplace can connect to Topsort’s ad server and render banners from active campaigns without complex integrations.

​
Installation

You can install the library using npm or yarn, or load the SDK directly in your HTML file by including a <script> tag: 
<script
  async
  type="module"
  src="https://unpkg.com/@topsort/banners@latest/dist/banners.mjs"
></script>
<script>
  // Global configuration for Topsort
  window.TS = {
    token: "TSE_XXXXXXXXXXXX", // Replace with your Topsort API key
  };
</script>

​
Usage

This example shows a minimal setup required to do it. The integration works with standard HTML and Javascript, making it compatible with most frontend stacks. To test it, you just need to add your Marketplace API Key and the banner slot id, configured in the campaign. 
<script
  async
  type="module"
  src="https://unpkg.com/@topsort/banners@latest/dist/banners.mjs"
></script>
<script
  async
  type="module"
  src="https://unpkg.com/@topsort/analytics.js/dist/ts.js"
></script>
<script>
  // Set API key for auctions and events
  window.TS = {
    token: "TSE_XXXXXXXXXXXX",
  };
  // Custom behavior can be configured for each site.
  window.TS_BANNERS = {
    // handle the destination link
    getLink(banner) {
      return `https://example.com/${banner.id}`;
    },
    // handle loading/fetching state
    getLoadingElement() {
      const el = document.createElement("div");
      el.innerText = "Loading...";
      return el;
    },
    // handle errors
    getErrorElement() {
      const el = document.createElement("div");
      el.innerText = "Error loading banner";
      return el;
    },
  };
</script>

  <topsort-banner width="600" height="400" id="<your slot id>"></topsort-banner>
