Angular Js And Google Api Client Js Gapi

Angular JS, a popular front-end framework, and Google API Client JS (gapi) are powerful tools when combined to create dynamic and interactive web applications. In this article, we will explore how you can integrate Google API services into your Angular JS projects using gapi to access a whole range of Google services such as Google Drive, Google Calendar, and more.

Setting up Angular JS with Google API Client JS (gapi)

To begin, you'll need to have an existing Angular JS project or create a new one. Next, you'll need to include Google API Client JS in your project. You can do this by adding the following script tag to your HTML file:

Html

This script tag will load the Google API Client JS library and make the `gapi` object available for use in your Angular JS application.

Authenticating with Google API

Before you can start making requests to Google APIs, you'll need to authenticate your application with Google. To do this, you can use the `gapi.auth.authorize` method provided by Google API Client JS.

Here's an example of how you can authenticate with Google API using `gapi`:

Javascript

gapi.auth.authorize({
  client_id: 'YOUR_CLIENT_ID',
  scope: 'https://www.googleapis.com/auth/drive https://www.googleapis.com/auth/calendar',
  immediate: false
}, authResult =&gt; {
    if (authResult &amp;&amp; !authResult.error) {
        // Authentication successful
    } else {
        // Authentication failed
    }
});

Replace `'YOUR_CLIENT_ID'` with your actual Google API Client ID. This code will prompt the user to authorize your application to access their Google Drive and Google Calendar data.

Making API Requests

Once you are authenticated, you can start making requests to Google APIs. For example, if you want to list files from Google Drive, you can use the following code snippet:

Javascript

gapi.client.drive.files.list({
  'pageSize': 10,
  'fields': "nextPageToken, files(id, name)"
}).then(response =&gt; {
  const files = response.result.files;
  if (files &amp;&amp; files.length &gt; 0) {
    files.forEach(file =&gt; {
      console.log(file.name);
    });
  } else {
    console.log('No files found.');
  }
});

This code snippet will fetch a list of the first 10 files in the user's Google Drive and log their names to the console.

Conclusion

In this article, we've discussed how you can integrate Google API services into your Angular JS projects using Google API Client JS (gapi). By following these steps, you can unlock the power of Google APIs and create rich and interactive web applications that leverage the capabilities of Google services. We encourage you to explore more Google APIs and experiment with different features to enhance your Angular JS applications further. Happy coding!
