scully-plugin-sitemap

This routeDiscoveryDone plugin for Scully that will generate one or more sitemaps for your generated routes.

Version 1.0.0 introduces breaking changes as the plugin has been rewritten to take advantage of the new routeDiscoveryDone plugin type rather the old way of using a render plugin. This has the major benefit of only generating the sitemaps once per run – instead of after each page render.

Installation

To install this library with npm run

$ npm install @gammastream/scully-plugin-sitemap --save-dev

Dependencies

The following peer dependencies are must be installed separately. Most are installed when install Angular or Scully. You'll likely only need to worry about fast-xml-parser and xmlbuilder.

  "peerDependencies": {
    "@scullyio/scully": "^1.0",
    "fast-xml-parser": "^3.17.4",
    "path-to-regexp": "^0.1.7",
    "xmlbuilder": "^13.0.2"
  },	

Usage

Within your Scully config (typescript), get and configure the plugin like so:

import { ScullyConfig, setPluginConfig } from '@scullyio/scully';
import { getSitemapPlugin } from '@gammastream/scully-plugin-sitemap';


const SitemapPlugin = getSitemapPlugin();
setPluginConfig(SitemapPlugin, {
    urlPrefix: 'https://gamma.stream',
    sitemapFilename: 'sitemap.xml',
    merge: false,
    trailingSlash: false,
    changeFreq: 'monthly',
    priority: ['1.0', '0.9', '0.8', '0.7', '0.6', '0.5', '0.4', '0.3', '0.2', '0.1', '0.0'],
    ignoredRoutes: ['/404'],
    routes: {
        '/products/:productId': {
            changeFreq: 'daily',
            priority: '0.9',
            sitemapFilename: 'sitemap-products.xml',
            merge: true
        },
    }
});

export const config: ScullyConfig = {
  projectRoot: './src',
  projectName: 'scully-plugins',
  outDir: './dist/static',
  routes: {
    '/products/:productId': {
        type: 'json',
        productId: {
            url: 'http://localhost:4200/assets/products.json',
            property: 'id',
        }
    }
  }
};

Build app and run scully like normal.

npm run build
npm run scully

Configuring Priority

The priority of a route can be configured by setting the priority level based on the number of segments in a given route.

[
	'1.0', // `/` - [ '' ] (1 segment)
	'0.9', // `/services` - [ '', 'services' ] (2 segments)
	'0.8', // `/services/hosting` - [ '', 'services', 'hosting' ]
	// etc...
]

Partial Generation with --routeFilter

Version 1.0.1 adds the merge flag. Setting the flag to true causes the generated routes to be merged into the existing sitemap file (if there is one). This allows users to generate a subset of routes without overwriting previously generated routes within the sitemap.

	// excerpt
    routes: {
        '/products/:productId': {
            changeFreq: 'daily',
            priority: '0.9',
            sitemapFilename: 'sitemap-products.xml',
            merge: true
        },
    }

SEO Optimization & Trailing Slash

Version 1.0.2 adds the trailingSlash flag. Setting the flag to true causes the url to be suffixed with a /. This is useful for SEO. You can set it for the main config or for individual routes.

const SitemapPlugin = getSitemapPlugin();
setPluginConfig(SitemapPlugin, {
    urlPrefix: 'https://gamma.stream',
    sitemapFilename: 'sitemap.xml',
    merge: false,
    trailingSlash: true,
});

Notes

• ~~Currently, the default priority (0.5) is assigned to all routes. Planned for a future update is the ability to assign a priority based on the number of segments in a route.~~ (Completed in v0.0.4)

• ~~Sitemap is regenerated with every route. At some time in the future, we expect Scully to support a class of plugins that run after it is finished generating all the routes.~~ (Completed in v1.0.0)
