Clear Site Data

The Clear-Site-Data HTTP header allows you to instruct browsers to clear all of their local data (caches, cookies, etc). This is useful in a number of cases, like when a user logs out.

Usage:

const clearSiteData = require("clearsitedata");

// Clear everything
app.post(
  "/logout",
  clearSiteData({
    directives: ["*"],
  }),
);

// Clearing everything is the default
app.post("/logout", clearSiteData());

// Only clear cookies and storage
app.post(
  "/logout",
  clearSiteData({
    directives: ["cookies", "storage"],
  }),
);
