Как создать шаблон html для страницы stati c из верхнего / нижнего колонтитула (и css / js inject) в Webpack 4 (шаблон loda sh не работает)?

Я пытаюсь создать страницы c html с помощью веб-пакета 4. Я использую html -webpack-plugin . Я хочу определить заголовок . html и нижний колонтитул. html и импортировать их позже на все html страницы. Но я также хочу, чтобы мои выходные файлы js и css автоматически вводились в этот верхний и нижний колонтитулы. Примерно так:

header. html: 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <title>Some Title</title>
    <% for(var i=0; i < htmlWebpackPlugin.files.css.length; i++) {%>
        <link type="text/css" rel="stylesheet" href="<%= htmlWebpackPlugin.files.css[i] %>">
    <% } %>
</head>
<body>

нижний колонтитул. html: 

    <% for(var i=0; i < htmlWebpackPlugin.files.js.length; i++) {%>
        <script type="text/javascript" src="<%= htmlWebpackPlugin.files.js[i] %>"></script>
    <% } %>
</body>
</html>

index.hbs (или index. html): 

<%= _.template(require('./../includes/header.html'))() %>

    <div class="content">
        <img src="img/bg/desktop/bg-index-03.jpg" width="500" height="500"/>
        <div class="imgtest"></div>
    </div> <!-- .content -->

<%= _.template(require('./../includes/footer.html'))() %>

Но я получаю в dist / index. html некоторую ошибку. Эти строки все те же и не загружают верхний / нижний колонтитул в индекс. html: 

<%= _.template(require('./../includes/header.html'))() %>
...
<%= _.template(require('./../includes/footer.html'))() %>

По некоторым причинам loda sh не работает ...

UPD :

Я изменил src/html/views/index.hbs на src/html/views/index.html (и в плагине) 

new HtmlWebpackPlugin({
  template: './src/html/views/index.html',
...

Добавить include строку здесь: 

{
    test: /\.html$/,
    include: path.resolve(__dirname, 'src/html/includes'),
    use: ['html-loader']
},

В верхнем / нижнем колонтитуле Я удалил loda sh код <% ... %>, оставив только чистый html - так оно и работает! Верхний / нижний колонтитул импортирован в index. html, но без css / js.

Если я верну loda sh обратно в нижний колонтитул. html (или header. html) 

<% for(var i=0; i < htmlWebpackPlugin.files.js.length; i++) {%>
    <script type="text/javascript" src="<%= htmlWebpackPlugin.files.js[i] %>"></script>
<% } %>

Я получаю ошибку: 

ERROR in Template execution failed: ReferenceError: htmlWebpackPlugin is not defined

ERROR in   ReferenceError: htmlWebpackPlugin is not defined

  - lodash.templateSources[2]:10 eval
    lodash.templateSources[2]:10:19

  - index.html:102 
    D:/.../src/html/views/index.html:102:110

  - index.html:104 ./node_modules/html-webpack-plugin/lib/loader.js!./src/html/views/index.html.module.exports

  - runMicrotasks

  - task_queues.js:93 processTicksAndRejections
    internal/process/task_queues.js:93:5

  - async Promise.all

Почему это происходит? Что не так? Как заставить loda sh работать в верхнем / нижнем колонтитуле?

Или каков наилучший способ создания html шаблонов?

Решено!

Я изменил inject на true в HtmlWebpackPlugin.

И я также добавил функцию generateHtmlPlugins() для автоматического добавления всех html -файлов в плагин от ./src/html/views.

src / html / includes / header. html: 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <title>Some Title</title>
</head>
<body>
<header>header</header>

src / html / includes / footer. html: 

    <footer>footer</footer>
</body>
</html>

src / html / views / index. html: 

<%= _.template(require('./../includes/header-main.html'))() %>
    <div class="content">
        <img src="img/bg/desktop/bg-index-03.jpg" width="500" height="500"/>
        <div class="imgtest"></div>
    </div>
<%= _.template(require('./../includes/footer.html'))() %>

dist / index. html: 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width,initial-scale=1,shrink-to-fit=no">
    <title>Some Title</title>
<link href="css/main.43f2075150009f972ed4.css" rel="stylesheet"></head>
<body>
<header>header</header>
    <div class="content">
        <img src="img/bg/desktop/bg-index-03.jpg" width="500" height="500">
        <div class="imgtest"></div>
    </div>
