Amazon Cognito Identitiy Promise

AWS Cognito for JS uses callbacks.

These make me want to die.

This library acts as an extension with promises

Promises

No more callback hell. I can code peacefully.

// Before
cognitoUser.authenticateUser(
    authDetails,
    {
        onSuccess: (session, userConfirmationNecessary) => {
            console.log(session, userConfrimationNecessary, "I want to die")
        },
        onFailure: (err) => {
            console.error(err, "Help")
        },
    }
)

// This library
(async () => {
    try {
        const [session, userConfrimationNecessary] =
            await cognitoUser.authenticateUser(authDetails)

        console.log(session, userConfrimationNecessary, "This is nice")
    } catch (err) {
        console.error(err, "Normal rejection handling")
    }
})

// Or if you prefer
const authenticate = cognitoUser.authenticateUser(authDetails)

Promise.resolve(authenticate).then(([session, userConfrimationNecessary]) => {
        console.log(session, userConfrimationNecessary, "This is also nice")
    })
    .catch((err) => {
        console.error(err, "Also normal rejection handling")
    })

Getters and Setters

For (almost) every method that is prefixed with get or set, a getter or setter has been created in addition to that method

// Before
cognitoUser.setSignInUserSession(myUserSession)
cognitoUser.getSignInUserSession()

// After
cognitoUser.setSignInUserSession(myUserSession)
cognitoUser.signInUserSession = myUserSession

cognitoUser.getSignInUserSession()
cognitoUser.signInUserSession
