Middleware to destroy caching

Package Exports

  • nocache
  • nocache/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (nocache) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Middleware to turn off caching

This Express middleware sets some HTTP response headers to try to disable client-side caching.

To use it:

const nocache = require("nocache");

// ...

app.use(nocache());

This sets three headers, disabling a lot of browser caching:

  • Cache-Control: no-store, no-cache, must-revalidate, proxy-revalidate
  • Expires: 0
  • Surrogate-Control: no-store

You may wish to do this if you want to ensure that users have up-to-date resources, or if you want to clear out an old version for some reason.
