Is it possible to use this library in postman pre-request script ? Postman requires, CDN equivalent of the library to load it in an environment variable.

You can use a CDN like jsdelivr.net to load the browser dist files from github tagged releases directly. To do that you may use both the import statement as well as the import() dynamic ESM loading function in your scripts.

E.g. using a dynamic import

const [
  { jwtVerify }, 
  { createRemoteJWKSet }
] = await Promise.all([
  import('https://cdn.jsdelivr.net/gh/panva/jose@3.19.0/dist/browser/jwt/verify.js'),
  import('https://cdn.jsdelivr.net/gh/panva/jose@3.19.0/dist/browser/jwks/remote.js')
])

const token = 'eyJraWQiOiJNRlplRzEwMmRRaXFiQU5vYU1sV19KbWY3Zk9abXRSc0h0NzdKRmhUcEYwIiwiYWxnIjoiRVMyNTYifQ.eyJmb28iOiJiYXIiLCJpYXQiOjE2MzM0MzU4MDF9.aYumnM7eTWpwIit6WGxFg8bYR3giAdZGzbbPi_4bUnS-HDjk01D50GQXI_A7Bu1pVrw3ELucwmV_vaQ4_v_EUQ'

const JWKS = createRemoteJWKSet(new URL('https://op.panva.cz/jwks'))

const { payload, protectedHeader } = await jwtVerify(token, JWKS)

console.log({ protectedHeader, payload })

Thanks for your response. Unfortunately postman doesn't support aync code (there are some workarounds but I am unable to figure out how this particular one can be used). If we can get something like this then it will be easier to load it in global variable in one go and then we can easily use the functions in pre-request or test scripts.
