Reading files on google drive without any auth

Is it possible to read a file from the drive thats open to public via api without the need of any authentication?

I have a static application built exclusively in javascript without any backend and Im planning to write a json in a file on google docs or drive, then read the json via api, but I cant use any thing that involves password because of the fact that people could just inspect the code and get the credentials. Can this be done with the drive/docs api or any other else where I need a password to write the file but not to read via request?

You can serve it with an Apps Script Web app

This will let you have a very light-weight and easy-to-manage back-end.

Create a new script and then paste this code for example:

function doGet() {

  // from https://json.org/example.html
  let json = {
    glossary: {
      title: "example glossary",
      GlossDiv: {
        title: "S",
        GlossList: {
          GlossEntry: {
            ID: "SGML",
            SortAs: "SGML",
            GlossTerm: "Standard Generalized Markup Language",
            Acronym: "SGML",
            Abbrev: "ISO 8879:1986",
            GlossDef: {
              para:
                "A meta-markup language, used to create markup languages such as DocBook.",
              GlossSeeAlso: ["GML", "XML"],
            },
            GlossSee: "markup"
          }
        }
      }
    }
  };

  return ContentService
    .createTextOutput(JSON.stringify(json))
    .setMimeType(ContentService.MimeType.JSON);
    
}

Replace the json variable, with the json content that you want.

Then deploy the web app:

Making sure that you select web app, and:

After which you will get a URL in this format:

https://script.google.com/macros/s/[ID]/exec

So now you can make a GET request to this endpoint to get the JSON! For example, if you visit it in the browser, you get:
