API

The GoogleAuth module exposes a single class, GoogleAuth, which contains the following method:

getUserInfo

This method retrieves user information using a given code and redirect URI.

Parameters

• code (Required): The authorization code you received from Google after user consent.
• redirect_uri (Required): The URI where the user was redirected after consent.

Example

const GoogleAuth = require('@loxjs/google-auth');

const googleAuth = new GoogleAuth({
    secret: {
        client_id: 'YOUR_CLIENT_ID',
        client_secret: 'YOUR_CLIENT_SECRET',
        grant_type: 'authorization_code'
    },
    timeout: 1000 * 60 * 2, // Optional, 2 minutes timeout
    proxy: { // Optional
        protocol: 'http',
        host: 'localhost',
        port: 8080,
        proxyAuth: 'user:password',
        headers: {
            'User-Agent': 'Node'
        }
    }
});

async function authenticate() {
    try {
        const userInfo = await googleAuth.getUserInfo({
            code: 'AUTHORIZATION_CODE',
            redirect_uri: 'YOUR_REDIRECT_URI'
        });
        console.log(userInfo);
    } catch (error) {
        console.error('Authentication failed:', error);
    }
}

authenticate();

Replace 'YOUR_CLIENT_ID', 'YOUR_CLIENT_SECRET', 'AUTHORIZATION_CODE', and 'YOUR_REDIRECT_URI' with your actual client ID, client secret, authorization code, and redirect URI, respectively.

Note

When using the proxy option, make sure the proxy settings are correct and the proxy server is properly configured to handle HTTPS over HTTP tunneling.

Error Handling

Errors are handled using the @loxjs/errors package. If the id_token is not present in the response, the Account.InvalidGoogleAuthToken error is thrown. Make sure to catch and handle errors appropriately in your implementation.

For more information on error handling, please visit @loxjs/errors on npmjs.
