AWS Extend Switch Roles

This Chrome extension code is designed to manage AWS IAM role switching configurations. It provides functionality to parse and load AWS config files in INI format, store and retrieve profiles using browser storage APIs (local, sync, session), and maintain profile data in IndexedDB for efficient access. The extension supports compressed storage of configuration data using LZString compression to handle storage size limits. It includes OAuth2 client logic to authenticate users against a custom domain (aesr.dev), handling authorization code flow with PKCE, token refresh, and fetching user-specific configuration from a remote API.

The extension listens to Chrome runtime events such as startup and installation to initialize and update profile data. It also handles external messages to update configuration securely by verifying sender IDs. Tab grouping features are implemented to manage AWS sessions, including automatic logout by opening and closing tabs upon tab group removal.

Key API and features used:

• Browser storage APIs (chrome.storage.local, chrome.storage.sync, chrome.storage.session)
• IndexedDB for persistent profile storage
• LZString compression for large config data
• OAuth2 PKCE flow with fetch API to https://auth.aesr.dev and https://api.aesr.dev
• Chrome runtime events (onStartup, onInstalled)
• Chrome tabs and tabGroups APIs for session management

No shell command execution, PowerShell usage, Windows Registry access, or direct file system operations are present. The code is not obfuscated; it is well-structured and readable with descriptive class and function names.

Example of network communication URLs:

fetch(`https://auth.${this.domain}/oauth2/token`, ...)
fetch(`https://api.${this.domain}/user/config`, ...)

Example of IndexedDB usage:

const openReq = indexedDB.open(this.dbName, this.version);
// Create object store 'profiles'

Example of storage usage:

this.storageArea.get(keys, resolve);
this.storageArea.set(items, ...);

Example of OAuth2 PKCE code verifier and challenge generation:

const codeVerifier = createCodeVerifier();
const codeChallenge = await createCodeChallenge(codeVerifier);

Overall, the code is focused on managing AWS role switching configurations securely and efficiently within a Chrome extension environment.
