Angular Universal Sitemap Generator

This package contains a CLI which is able to create a sitemap.xml file at build time.

The CLI only works in combination with Angular SSR and Prerendering. The routes from the prerendered pages are being used to generate the sitemap. This package can be used in CI/CD as it does not crawl a running website.

Installation

npm install ngx-sitemap --save-dev

Usage

In order to work you must first prerender all routes to be included in the sitemap.xml.

Then, use it from the command line as follows:

ngx-sitemap <srcDirectory> <baseUrl>

Example:

ngx-sitemap ./dist/prod/browser htts://www.example.com

This will generate a sitemap.xml in the srcDirectory given.

How it works

Prerendering will generate a static website with prerendered pages in the dist folder in a format like this:

dist
└── prod
    ├── browser
    │    ├── route1
    │    │   └── index.html
    │    ├── route2
    │    │   ├── route3
    │    │   │   └── index.html
    │    │   ├── route4
    │    │   │   └── index.html
    │    │   └── index.html
    │    ├── index.html
    │    ├── main.js
    │    ├── runtime.js
    │    └── ...
    └── server
        └── ...

The Command expects the srcDirectory which in this case would be ./dist/prod/browser. It then lists all routes which end with index.html resulting in the following:

[
    '/'
    'route1',
    'route2',
    'route2/route3',
    'route2/route4',
]

Once all routes are found they get written into the sitemap.xml as follows:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="https://www.sitemaps.org/schemas/sitemap/0.9">
    <url>
        <loc>https://www.example.com</loc>
    </url>
    <url>
        <loc>https://www.example.com/route1</loc>
    </url>
    <url>
        <loc>https://www.example.com/route2</loc>
    </url>
    <url>
        <loc>https://www.example.com/route2/route3</loc>
    </url>
    <url>
        <loc>https://www.example.com/route2/route4</loc>
    </url>
</urlset>

Once deployed, the sitemap is available under https://www.example.com/sitemap.xml.
