First of all, please note that token expiration and revoking are two different things.

1. Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
2. Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

Quoted from JWT RFC:

Wiring up a Google Form to GitHub is not that difficult with a little bit of Apps Script automation. All you need is a Google account, a GitHub account, and a web browser...

Set up your GitHub Personal Access Token

Personal access tokens provide an easy way to interact with the GitHub API without having to mess with OAuth. If you don't already have a personal access token with repo or public_repo access, visit your GitHub settings page and generate a new token.

Be sure to copy your token some place safe and keep it secure. Once generated, you will not be able to view or copy the token again.

Set up the Form & Spreadsheet

1. Create a Google Form.

Auto-deploying built products to gh-pages with Travis

This is a set up for projects which want to check in only their source files, but have their gh-pages branch automatically updated with some compiled output every time they push.

Create a compile script

You want a script that does a local compile to e.g. an out/ directory. Let's call this compile.sh for our purposes, but for your project it might be npm build or gulp make-docs or anything similar.

The out/ directory should contain everything you want deployed to gh-pages. That almost always includes an index.html.
