Feature Specification: Export Telegram Group Members
Feature Branch: 001-export-telegram-members
Created: 2025-12-06
Status: Draft
Input: User description: "Build an application that can help me export Telegram group members info, into a json file"
User Scenarios & Testing (mandatory)
User Story 1 - Export Telegram Group Members (Priority: P1)
As a Telegram group administrator or member, I want to export the list of group members to a JSON file so that I can analyze the member data, backup group information, or use it for other purposes outside of Telegram.
Why this priority: This is the core functionality of the application - without this primary feature, the application has no value.
Independent Test: The application can be tested by connecting to a Telegram group and successfully exporting its members to a JSON file that contains all required member information fields.
Acceptance Scenarios:
- Given I have valid Telegram credentials and access to a group, When I run the export application targeting that group, Then I receive a JSON file containing all member information for that group
- Given I have a Telegram group with 100 members, When I export the member list, Then the JSON file contains exactly 100 member entries with their respective details
User Story 2 - Select Specific Group for Export (Priority: P2)
As a user managing multiple Telegram groups, I want to be able to select which specific group I want to export members from so that I can target the right group for my data needs.
Why this priority: Users may have multiple groups and need to ensure they're exporting from the correct one.
Independent Test: The application presents a list of accessible groups for the user to select from, and exports members from the chosen group.
Acceptance Scenarios:
- Given I have access to multiple Telegram groups, When I run the export application, Then I can select which group to export members from
User Story 3 - Export Custom Member Information Fields (Priority: P3)
As a user, I want to select which specific member information fields to export so that I can customize the output to contain only the data I need.
Why this priority: Users may have privacy considerations or only need specific data fields, making the export more efficient and privacy-conscious.
Independent Test: The application allows users to select which member attributes to include in the export (e.g., username, user ID, first name, last name).
Acceptance Scenarios:
- Given I want to export only specific member information, When I configure the export settings, Then the JSON file contains only the selected fields
Edge Cases
- What happens when a group has more than 10,000 members that Telegram may limit access to?
- How does the system handle private groups where the user doesn't have sufficient permissions?
- What happens when the Telegram API temporarily blocks requests due to rate limiting?
- How does the system handle groups where some member information is restricted by privacy settings?
- What happens when internet connection is interrupted during export?
- How does the system handle users who have deleted their Telegram accounts (ghost users)?
