Script Tag Integration
Script tag integration is the simplest method of adding third-party functionality to a website. By pasting a single <script> tag into your HTML, the external service loads its JavaScript, initializes, and renders any UI components (like a chat widget) — with no npm installation, bundler configuration, or framework-specific setup required.
Why script tags still matter
Despite the rise of npm packages and bundled JavaScript, script tag integration remains the lowest-friction deployment method. It works on any website regardless of tech stack — static HTML, WordPress, Webflow, Squarespace, or custom applications. For support tools, this means deployment in minutes instead of a development sprint.
Script tag vs npm package
Script tags are ideal for quick deployment and non-React sites. npm packages (like @echosdk/react) offer deeper integration: type safety, component props, lifecycle hooks, and tree-shaking. Most modern support SDKs offer both options — script tag for speed, npm package for control.
EchoSDK's script tag
EchoSDK's widget deploys with a single script tag containing your app ID. The script loads asynchronously (no page speed impact), initializes the chat widget, and connects to EchoSDK's backend. For React applications, the @echosdk/react package provides a component-based alternative with full TypeScript support.
