A simple nodejs package to generate sitemap.xml file a json file.
The generated sitemap.xml will follow all the guidelines listed in official schema at Sitemap Protocol
In it's simplest form, following is how you would add json data and generate sitemap. Please note, calling 'addJsonUrls' will add the data to the package and also returns whether or not the json is validated against the schema.
var {addJsonUrls, generateSiteMap} = require('json-sitemap');
var data = require('./sitemap-data.json');
let addDataResult = addJsonUrls(data);
console.log('validation:', addDataResult);
var sitemap = generateSiteMap({
domain: 'https://dashboard.covid19fighters.page',
styleSheet: "default.xsl"
});
console.log(sitemap);Given following json...
