This repository serves as a comprehensive reference library for browser extension development, providing a collection of code samples and implementation patterns. It is designed to help developers understand the requirements for building extensions that adhere to current manifest standards, specifically focusing on the transition to and implementation of version three specifications.
The project provides functional examples for core extension capabilities, including the use of event-driven background service workers, isolated content script injection, and message-passing for inter-process communication. It demonstrates how to configure extension metadata, manage browser UI customizations like action-triggered popups, and integrate various web APIs to modify browser behavior.
These resources cover the full lifecycle of extension development, from initial manifest configuration and local directory loading for debugging to the final packaging and publication process. The repository is structured to assist with both learning individual API usage and building complex, multi-component extensions using standard web technologies.
