Suppose if i have an handle bar template file (.hbs), then how i can substitute my translated variables in that directly rather than using 'template' variable and specifying my html (handlebar template) in that

example

base.hbs
base.txt

<!DOCTYPE html>
<html lang="en">

<head>
  <meta charset="UTF-8">
  <title>handlebars-i18n Demo</title>
<body>
  <h2>handlebars-i18n Demo</h2>
    <dds-dotcom-shell-container>
    {{> @partial-block }}   // all my template is in files, how do i translate my variables in here
  </dds-dotcom-shell-container>
