I’ve built several things with it. It’s evolving fast and the DX is quite good. For example, its inspect snapshot test is unique and super useful, combining with its unique way to represent string with `#|`.

Loro Inspector is here! Now you can directly browse the current state and complete edit history of your Loro documents in the browser. You can also use this tool to time travel to any version in the history of your Loro document.

It's so hard to feel this warmth from interactions on social platforms these days 🥹

Myers diff may generate weird deltas like the following example. It will make concurrent text updates generate weird merge results. Any suggestions? My current thought is to implement an A* search on top of the edit graph that punishes noncontinuous edits

You may experience data loss due to the following issues caused by incorrect usage of CRDTs libraries, regardless of whether you're using Loro, Automerge, or Yjs. Here is how to avoid them:

Container Overwrites
When initializing child containers in parallel, overwrites can occur instead of automatic merging. For example:

const doc = new LoroDoc();
const map = doc.getMap("map");

// Parallel initialization of child containers
const docB = doc.fork();
const textA = doc.getMap("map").setContainer("text", new LoroText());
textA.insert(0, "A");
const textB = docB.getMap("map").setContainer("text", new LoroText());
textB.insert(0, "B");

doc.import(docB.export({ mode: "update" }));
// Result: Either { "meta": { "text": "A" } } or { "meta": { "text": "B" } }
This behavior can lead to serious data loss issues. If a container holds significant data or even the entire document's content, overwriting it could result in unexpected loss of important information. While the complete editing history is preserved and allows for potential recovery of user data, the recovery process can be complex.
