My goal is to check if a Cognito token is valid and not expired. I found this interesting and friendly package. https://www.npmjs.com/package/verify-cognito-token
I have already implemented it as an AWS lambda function, but for some reason I'm getting an error response.
//required params
const params = {
region: '<your-aws-region>',
userPoolId: '<your-user-pool-id>'
}
//optional claims examples
const claims = {
aud: '<your-app-client-id>',
email_verified: true,
auth_time: time => time <= 1524588564,
'cognito:groups': groups => groups.includes('Admins')
}
const Verifier = require('verify-cognito-token');
const verifier = new Verifier(params, claims);
verifier.verify(token)
.then(result =>{
//result will be `true` if token is valid, non-expired, and has matching claims
//result will be `false` if token is invalid, expired or fails the claims check
})
