Description

I need to know if this is the right code so that after my token expires, call a refresh token to not stop my app.

MSAL Configuration

//MSAL configuration
const msalConfig = {
    auth: {
        clientId: '7e391644-15a5-47d4-9cd6-5d86711f4c66',
        authority: 'https://login.microsoftonline.com/92d143fd-f58c-420c-8469-393fab93e1ea',
        redirectUri: 'http://localhost:8080'
    }
};
const msalRequest = { scopes: ['user.read'] };
function ensureScope (scope) {
    if (!msalRequest.scopes.some((s) => s.toLowerCase() === scope.toLowerCase())) {
        msalRequest.scopes.push(scope);
    }
}
// Inicializa a Biblioteca MSAL.
const msalClient = new msal.PublicClientApplication(msalConfig);

// Conecta o usuário.
async function signIn() {
    const authResult = await msalClient.loginPopup(msalRequest);
    sessionStorage.setItem('msalAccount', authResult.account.username);
}
// Manipula a obtendo um token de acesso que Microsoft Graph pode usar.
async function getToken() {
    let account = sessionStorage.getItem('msalAccount');
    if (!account) {
        throw new Error(
            'As informações do usuário foram apagadas da sessão. Saia e faça login novamente.');
    }
    try {
        // Primeiro, tente obter o token silenciosamente
        const silentRequest = {
            scopes: msalRequest.scopes,
            account: msalClient.getAccountByUsername(account)
        };

        const silentResult = await msalClient.acquireTokenSilent(silentRequest);
        return silentResult.accessToken;
    } catch (silentError) {

        // Se as solicitações silenciosas falharem com InteractionRequiredAuthError,
        // tenta obter o token interativamente

        if (silentError instanceof msal.InteractionRequiredAuthError) {
            const interactiveResult = await msalClient.acquireTokenPopup(msalRequest);
            return interactiveResult.accessToken;
        } else {
            throw silentError;
        }
    }
}

@bmahall my goal is to bring a refresh token to my app, so when my access token expires it calls another one… because when my app has an expired token I can’t access the database.
