Now that we have successfully setup our Blog. We should ensure that it is AMP valid. To validate a website that is online we can just visit validator.ampproject.org and type in our url.

If we want validate before publishing we could use the AMP ChromeExtension. Or we can do it by adding #development=1 to the url we want to check in the Browser. If we than open the Browsers JS Console it should tell us that the AMP validation was successful:

Powered by AMP ⚡ HTML – Version 1457112743399
AMP validation successful.

Unfortunately, if that is not the case, the cause of a Failure is not shown. Therefor we should install an AMP Validator locally in order to check whether our website is valid. Additionally we can validate the hole Site at once.

The Steps I took Today:

1. install the npm Package amphtml-validator by running the command npm install amphtml-validator --save-dev
2. add validator.js, a Script based on amp-validator demo.js
3. start local Validator by running node validator.js
