Hi HN, I am the author of the open source spreadsheet Luckysheet. Luckysheet's github repository has won 6K+ star in 5 months. Thank you for your love. This time we opened the java backend to support collaborative editing. Demo - http://luckysheet.lashuju.com/demo/ http://luckysheet.lashuju.com/demo/ 1. After the user operates, the data is distributed quickly 2. Simple configuration, one-click Docker deployment 3. Support secondary development 4. Apache-2.0 License Links: Luckysheet - https://github.com/mengshukeji/Luckysheet https://github.com/mengshukeji/Luckysheet LuckysheetServer - https://github.com/mengshukeji/LuckysheetServer https://github.com/mengshukeji/LuckysheetServer Welcome to communicate if you have any questions :)

  Great work! How does the Java / Postgres application scale? How many concurrent users can it support?
  - alexliu518 6y ago
    It can be regarded as an ordinary docker application, and k8s is recommended. Postgres can split table by listid, but the database is not recommended to be installed with docker Concurrency has not been tested yet

Be careful of chinese developers repos, you might end up loosing your precious data, corporate secrets. These repos might be state owned.

  This seems like a bold claim. Could you provide some evidence? If it's not hosted in China is there a risk? Keen to learn more.
  - adydaddy 6y ago
    Well well probably you don't see your firewall logs.
  - adydaddy 6y ago
    Also what evidence google can give you about removal of chinese apps containing virus? Because you feel china is a friendly nation it doesn't mean they r saints.

  I guess that would explain why there was a large pooh image on the spreadsheet. The meme just flew over my head.

  Despite the source being open and hosted in an American owned company, you still made it a point to wear your Tinfoil hat on?
  - anaganisk 6y ago
    Why the down vote? Are you telling me that somehow we're supposed to trust US agencies to not go thru our secrets? And china bad?
    - adydaddy 6y ago
      Reliable goon vs unreliable goon is the difference between US and China.

Congratulations on some incredible work, Alex. Are you considering going into the hosting business? Seems like a logical progression.

What conflict resolving algorithm do you use? OT or CRDT? I didn't see it mentioned anywhere
- Hitton 6y ago
  In documentation it mentions it's using OT.

@alexliu518 do you have an example for a Vue.js + Node.js backend with simple saving and updating? Is this possible or do I need to run the Java backend + services?
- alexliu518 6y ago
  There is no Node.js backend for the time being, we are considering plans for more backends in other languages We have collected the backends of java, .NET and Golang versions provided by the community. Welcome to the community to provide another Node.js version.

Really impressive. Especially considering how small the developer team is.
