JwtInvalidationExpress

NodeJS Express server that exemplifies how to invalidate JWT's by their "issued at" claim value.

Purpose

This is a sample Express HTTP server that demonstrates how to invalidate JSON web tokens by its creation time (a. k. a. its iat claim).

It uses ES Modules and modern JavaScript syntax. While I did not test, it probably works with NodeJS v16.9.0 and above, but in all honesty, I have only ever run it in NodeJS v18. Note that the wj-config package imposes a minimum NodeJS version of 16.9.0.

Read this article for a detailed explanation of how all this works.

Have fun!

How to Run This

  1. Ensure a proper modern version of NodeJS.
  2. Clone this repository.
  3. Open bash or PowerShell in the /src folder and run npm ci.
  4. Create a MySQL database and a corresponding user.
  5. Create the MySQL table using the SQL file provided in the /sql folder.
  6. Configure your MySQL server and database details in /src/config.js.
  7. Open the repository in Visual Studio Code and just press F5 (Run command). It will work because this repository has the necessary launch.json file.
  8. If not running it with Visual Studio Code, just launch node ./src/index.js.
  9. Now the HTTP server is accessible through the URL http://localhost:7777/.
