Role of PHP file in PWA

问题

I am new to the PWA. So I was trying to create a basic website. which include index.html, manifest, serviceworker file, answer.php. Answer.php is running on server. on clicking a button in index.html, it goes to answer.php where data is obtained from the database. I am caching all the files except serviceworker and answer.php.

Q1: Should I cache answer.php?

Q2: If not, then how can I connect it to indexed db (represent data obtained from server in the form of html file).

Q3: what is the role of server files in PWA.

Q1: Should i cache answer.php?

I don't think so, since its generating data querying the database.

Q2: If not, then how can i connect it to indexed db (represent data obtained from server in the form of html file).

You can use answer.php to return a JSON to your PWA: Manual JSON Encode

Q3: what is the role of server files in PWA

Any backend services. I.E.: How to build a JSON backend with PHP
