AMP-Toolbox update-cache


Generates AMP Cache invalidation URLs for all known AMP Caches. For more info see the Google AMP Cache documentation.

Usage

Install via:

``sh
npm install @ampproject/toolbox-update-cache
`

Generate a list of update URLs like this:

`javascript
const UpdateCacheUrlProvider = require('@ampproject/toolbox-update-cache');

// Load the private key, generated as described on
// https://developers.google.com/amp/cache/update-cache#rsa-keys
const privateKey = '...';

// Create an instance of the factory using the private key.
const updateCacheUrlProvider = UpdateCacheUrlProvider.create(privateKey);

updateCacheUrlProvider.calculateFromOriginUrl('https://www.example.com')
.then(cacheUpdateUrls => {
cacheUpdateUrls.forEach(cacheUpdateUrlInfo => {
console.log('Cache ID:' + cacheUpdateUrlInfo.cacheId);
console.log('Cache Name:' + cacheUpdateUrlInfo.cacheName);
console.log('cache-update URL:' + cacheUpdateUrlInfo.updateCacheUrl);
});
});
``

Note: this only generates the URLs, but doesn't perform the actual update request.
