Project Description

1. This project is modified based on the Luckysheet source code.Please comply with the original author's open-source licenseanddo not delete or modify the copyright notices in the source code headers.。
2. This project is open-sourced under the Apache2.0 License. Feel free to use it. At the same time, this project will also contribute back to the Luksysheet community to enrich its ecosystem. Special thanks again to the @Luckysheet team ❤️
3. This project is Luckysheet Collaboration Enhanced Edition (Full Feature Implementation), with the aim ofproviding collaborative implementation ideas, data storage services, and collaboration demonstrationsand more. The project is built on Luckysheet. Thanks to the original authors for making it open source.
4. This project primarilyimplements collaborative featuresmodules, and all modifications to the source code are reflected in the luckysheet-source-private directory;
5. The project supports optional database services. Without a database, user data cannot be persistently stored, but collaborative features are not affected.⚠️ Only applicable to the master and master-alpha branches. master-vue relies on database functionality to implement the user system.。
6. The project uses Sequelize as its ORM data service technology, supporting databases such as MySQL, SQLite, PostgreSQL, and MSSQL, making it easy for users to migrate quickly.
7. The project uses Typescript as the primary development language, providing complete type hints to standardize code and improve development efficiency.
