Create an web component in components.

<script>
  import Component from "@primate/webc/Component";
  import PostLink from "./post-link.webc";

  export default class PostIndex extends Component {
    mounted(root) {
      root.querySelector("h1").addEventListener("click",
        _ => console.log("title clicked!"));
    }

    render() {
      const { posts } = this.props;

      return `<h1>All posts</h1>
        ${posts.map(post => new PostLink({post})).join("")}
     `;

</script>

And another component for displaying post links.

      const { post } = this.props;
      return `<h2><a href="/post/view/${post.id}">${post.title}</a></h2>`;
    }
  }
</script>

Create a route and serve the post-index component.

import view from "primate/handler/view";

const posts = [{
  id: 1,
  title: "First post",
}];

export default {
  get() {
    return view("post-index.webc", { posts });
