The HTML Template

Factor apps use a single HTML file as a template for all pages: index.html. This file is required and should exist in your source folder next to your other entry files (e.g. index.ts, server.ts)

Any standard HTML you include in this file will appear on all pages of your application. That makes index.html and easy place to add tag managers or analytics code.

For dynamic content, Factor replaces some standard variables with associated content on build:

  • <!--factor-body--> - This tag will be replaced with the page body content
  • <!--factor-head--> - This tag will be replaced with dynamic meta information for the page
  • <!--factor-debug--> - This tag will be replaced with available debugging information such as the currently rendered page.

A typical index.html file will look like this:

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <link rel="shortcut icon" href="/favicon.png" />

  <body class="factor-app">
    <div id="app"><!--factor-body--></div>
