Clearing GitHub Notifications with a Shell Script: An Introduction to Underutilized GitHub API Endpoints

Introduction

In the bustling world of software development, GitHub has become an indispensable platform for collaboration, version control, and open-source contributions. With its vast array of features, GitHub offers a rich ecosystem of tools and services. However, its notification system, while essential for staying informed about project updates and activities, can quickly become overwhelming, particularly for developers working on multiple projects or those contributing to large open-source repositories.

This article delves into an often overlooked aspect of GitHub's API - the ability to programmatically manage notifications. By harnessing this power, we can automate the process of clearing notifications, allowing developers to focus on what matters most - building exceptional software. We will explore the key concepts, techniques, and tools involved in building a shell script to clear GitHub notifications efficiently.

Understanding GitHub Notifications and the API

GitHub notifications are triggered by various events, including:

New issues or pull requests on repositories you follow or contribute to.
Mentions or replies to comments you've made.
New releases or updates to projects you're watching.
Team invitations or requests.

While these notifications are essential for staying updated, they can quickly pile up, leading to information overload. GitHub provides a REST API that allows developers to interact with the platform's resources programmatically. This API provides endpoints for manipulating notifications, including clearing them, marking them as read, and filtering them by type.

Key Concepts:

GitHub API:
A set of endpoints that allows developers to interact with GitHub resources programmatically.
Authentication:
Accessing the API requires authentication using an API token, ensuring secure communication and authorization.
API Endpoints:
Specific URLs that correspond to different actions or resources within the API, such as clearing notifications or fetching user information.
HTTP Requests:
Communication with the API is done through HTTP requests, typically using methods like GET, POST, PUT, or DELETE.

Building a Shell Script to Clear Notifications

Let's craft a shell script that effectively clears our GitHub notifications. The script will utilize the GitHub API, authenticate using a personal access token, and perform the necessary HTTP requests to clear the notifications.

1. Obtaining a Personal Access Token

Log in to your GitHub account.
Navigate to
https://github.com/settings/tokens/new .
Give your token a descriptive name and select the "repo" scope for notification management.
Click "Generate token" to create your personal access token.
Store this token securely as you will need it for authentication.

2. Choosing a Programming Language

While we can use any language with HTTP capabilities (Python, JavaScript, Ruby), we'll demonstrate using Bash scripting for its simplicity and common availability.

3. Scripting with `curl`

The curl command is a versatile tool for making HTTP requests from the command line. We will use it to interact with the GitHub API.

Here's a basic shell script to clear all notifications:



        

        #!/bin/bash
    # Your GitHub personal access token
    TOKEN='YOUR_PERSONAL_ACCESS_TOKEN'

    # The GitHub API endpoint for clearing notifications
    API_URL='https://api.github.com/notifications'

    # Authenticate using the token
    curl -H "Authorization: token $TOKEN" -X DELETE $API_URL
    </code>
    </pre>





    

     Explanation:

    

   





    


     


      #!/bin/bash


     
     :  Specifies the interpreter to use for the script.
    


    


     


      TOKEN='YOUR_PERSONAL_ACCESS_TOKEN'


     
     : Sets the environment variable TOKEN to your generated personal access token.
    


    


     


      API_URL='https://api.github.com/notifications'


     
     : Defines the API endpoint for clearing all notifications.
    


    


     


      curl -H "Authorization: token $TOKEN" -X DELETE $API_URL


     
     : Uses curl to send a DELETE request to the API endpoint, authenticated with the provided token.
    


   





   





    4. Error Handling and Logging


   





   


    To make your script robust, implement error handling and logging to capture any potential issues during execution.


   





   


        


        #!/bin/bash

    # Your GitHub personal access token
    TOKEN='YOUR_PERSONAL_ACCESS_TOKEN'

    # The GitHub API endpoint for clearing notifications
    API_URL='https://api.github.com/notifications'

    # Set the output format for curl
    curl_opts="-s -w '%{http_code}' -o /dev/null"

    # Perform the DELETE request
    response_code=$(curl $curl_opts -H "Authorization: token $TOKEN" -X DELETE $API_URL)

    # Check the response code
    if [ "$response_code" -eq 204 ]; then
        echo "Notifications cleared successfully!"
    else
        echo "Error: Could not clear notifications. Response code: $response_code"
    fi
    </code>
    </pre>






    

     Explanation:

    

   





    


     


      curl_opts="-s -w '%{http_code}' -o /dev/null"


     
     : Sets options for curl to suppress output, capture the HTTP response code, and discard the response body.
    


    


     


      response_code=$(curl $curl_opts -H "Authorization: token $TOKEN" -X DELETE $API_URL)


     
     : Executes the DELETE request and stores the response code in the response_code variable.
    


    


     


      if [ "$response_code" -eq 204 ]; then ... else ... fi


     
     : Checks if the response code is 204 (successful deletion), displaying appropriate messages based on the outcome.

Advanced Features: Filtering and Granular Control

While the basic script clears all notifications, we can enhance its functionality by implementing filtering and granular control over notification management. Let's explore some of the underutilized GitHub API endpoints that empower us with more refined control.

1. Filtering Notifications by Type

The GitHub API allows you to filter notifications based on the type of event that triggered them. The following table outlines some common notification types and their corresponding API parameters:

Notification Type	API Parameter
Issues	`all`
Pull Requests	`pull_request`
Releases	`release`
Team Invitations	`team_invitation`
Repository Watches	`repository_watch`

Example: Clearing notifications related to pull requests only:




        


        #!/bin/bash

    TOKEN='YOUR_PERSONAL_ACCESS_TOKEN'
    API_URL='https://api.github.com/notifications?all=false&amp;participating=false&amp;unread=false&amp;reason=pull_request'

    curl_opts="-s -w '%{http_code}' -o /dev/null"
    response_code=$(curl $curl_opts -H "Authorization: token $TOKEN" -X DELETE $API_URL)

    if [ "$response_code" -eq 204 ]; then
        echo "Pull request notifications cleared successfully!"
    else
        echo "Error: Could not clear notifications. Response code: $response_code"
    fi
    </code>
    </pre>







    2. Marking Notifications as Read

   





    Instead of deleting notifications, you can mark them as read to keep them in your notification feed but indicate that you've acknowledged them. The API endpoint for this action is https://api.github.com/notifications with a POST request.


   





   


        


        #!/bin/bash

    TOKEN='YOUR_PERSONAL_ACCESS_TOKEN'
    API_URL='https://api.github.com/notifications'

    curl_opts="-s -w '%{http_code}' -o /dev/null"
    response_code=$(curl $curl_opts -H "Authorization: token $TOKEN" -X POST $API_URL)

    if [ "$response_code" -eq 204 ]; then
        echo "Notifications marked as read successfully!"
    else
        echo "Error: Could not mark notifications as read. Response code: $response_code"
    fi
    </code>
    </pre>







    3. Accessing Specific Notifications

   





    The GitHub API allows you to access specific notifications using their unique identifiers. You can retrieve details about a notification, mark it as read, or delete it individually. This approach provides the most granular control over notification management.


   





   


        


        #!/bin/bash

    TOKEN='YOUR_PERSONAL_ACCESS_TOKEN'
    NOTIFICATION_ID='YOUR_NOTIFICATION_ID'

    # Mark a notification as read
    API_URL="https://api.github.com/notifications/threads/$NOTIFICATION_ID"

    curl_opts="-s -w '%{http_code}' -o /dev/null"
    response_code=$(curl $curl_opts -H "Authorization: token $TOKEN" -X PATCH $API_URL -d '{"reason": "read"}')

    if [ "$response_code" -eq 204 ]; then
        echo "Notification $NOTIFICATION_ID marked as read successfully!"
    else
        echo "Error: Could not mark notification as read. Response code: $response_code"
    fi

    # Delete a specific notification
    API_URL="https://api.github.com/notifications/threads/$NOTIFICATION_ID"

    curl_opts="-s -w '%{http_code}' -o /dev/null"
    response_code=$(curl $curl_opts -H "Authorization: token $TOKEN" -X DELETE $API_URL)

    if [ "$response_code" -eq 204 ]; then
        echo "Notification $NOTIFICATION_ID deleted successfully!"
    else
        echo "Error: Could not delete notification. Response code: $response_code"
    fi
    </code>
    </pre>
