Nunjucks dynamic page template

3.3k views Asked by Ingo Köpp At 01 August 2017 at 13:59

i'm using nunjucks (gulp) as templating language and i want to build a dynamic page template.

This is my Json:

"pages": [
    {
        uname: "Welcome",
        title: "Page 1 Headline"
    },
    {
        uname: "About",
        title: "Page 2 Headline"
    }
]

Currently i have a static page (html) template for each page:

{% extends "layout.html" %}
{% set active_page = "Welcome" %} //<- This needs to be dynamicly
{% block content %}

<h1>{{ page[0].title }}</h1> //<- This needs to be dynamicly

My first thought was to read the url parameters but i couldn't solve it in this way.

Any suggestions?

The solution was simple!

Need to do this:

index.njk

<!-- set title !!! -->
{% set title = 'home page' %} <!-- set title !!! -->
{% extends "layout.njk" %}

{% block header %} {% include "parts/header.njk" %} {% endblock %}
{% block main %}
<main class="main">
    <!-- content -->
</main>
{% endblock %}
{% block footer %} {% include "parts/footer.njk" %} {% endblock %}

page1.njk

<!-- set title !!! -->
{% set title = 'page1' %}
{% extends "layout.njk" %}

{% block header %} {% include "parts/header.njk" %} {% endblock %}
{% block main %}
<main class="main">
    <!-- content -->
</main>
{% endblock %}
{% block footer %} {% include "parts/footer.njk" %} {% endblock %}

layout.njk

<!-- layout.njk -->

<html lang="en">
    <head>
      <!-- here is the compiled title -->
      <title>{{ title }}</title>
      <link rel="stylesheet" href="styles/style.css">
    </head>
    <body class="page">
        {% block header %}{% endblock %}
        {% block main %}{% endblock %}
        {% block footer %}{% endblock %}
    </body>
 </html>

{% macro inc(file, folder) %}
    {% if folder %}
        {% set folderPATH = folder %}
    {% else %}
        {% set folderPATH = file %}
    {% endif %}
    {% set path = folderPATH + "/" + file + ".njk" %}
    {% include path %}
{% endmacro %}

{{ inc("menu") }} // {% include "menu/menu.njk" %}
{{ inc("content") }} // {% include "content/content.njk" %}

If you are hoping to pass the data from data.json file

first you need to use someway to specify the page name in the data file itself.
Then you have to set the page name as a variable in the nunjucks page.
Now you can use this variable name to get the data relevant to the page you are working in.

data.json

{
    "pages": {
        "welcome": {
           "uname": "Welcome",
           "title": "Page 1 Headline"
        },
        "about": {
           "uname": "About",
           "title": "Page 2 Headline"
        },
    }
}

index.njk

{% set pageName = 'welcome' %}
{% extends "layout.html" %}
{% set active_page = "Welcome" %}
{% block content %}

<h1>{{ page[pageName].title }}</h1>
