This is the error I am facing, however when I remove the integrity attribute from jquery there seems to be no error. What is integrity here how does it help my website. Can I remove it ?

1) *Failed to find a valid digest in the 'integrity' attribute for resource 'https://code.jquery.com/jquery-3.3.1.min.js' with computed SHA-256 integrity 'FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8='. The resource has been blocked.
util.js:55 

2) Uncaught TypeError: Cannot read property 'fn' of undefined

  • You can use the libraries without the integrity attribute. As for what it is - https://stackoverflow.com/questions/32039568/what-are-the-integrity-and-crossorigin-attributes – Anurag Srivastava Mar 04 '19 at 09:23

  • It's a cryptographic key to validate the "integrity" of the CDN... You cannot change the file source from jQuery slim to jQuery full version and use the same key. [W3C specification](https://www.w3.org/TR/SRI/#resource-integrity) – Louys Patrice Bessette Mar 04 '19 at 09:27

    I just want to add that it is a good practice to use `Integrity` attribute. Using Cloudflare [CDN](https://cdnjs.com/libraries/twitter-bootstrap), just click on `copy > Copy Script Tag with SRI` – awran5 Mar 04 '19 at 09:38
