ESM HTTP imports

Thu, 22 Dec 2022 00:00:00 GMT

When using all modern versions of JS you can use esm modules.

What I did not realise is you can import modules at runtime over http(s).

To help with this there are a range of CDNs that host the whole of NPM designed for ESM.

Some examples include:

https://esm.sh/
https://esm.run/ - from: https://www.jsdelivr.com/

Example

import { version, verify } from "https://esm.run/jsonwebtoken-esm";

console.log(version); // "8.5.1" at time of writing.
const token =
  "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwic2NvcGVzIjpbImEiLCJiIl0sImlhdCI6MTUxNjIzOTAyMn0.RYe2h0fD7XqWDxSepytntccG5-EfrdGmVmqwfhi36O0";
const decoded = verify(token, "your-256-bit-secret");
console.log(decoded);
