{"version":"1.0","type":"rich","title":"Mimmicking Deps.autorun from Meteor in pure Node","description":"This example demonstrates a pure Node.js implementation of Meteor’s reactive `Deps.autorun` pattern, showing how dependent computations automatically re-run when their data sources change. The code uses Node’s `EventEmitter` to simulate a reactive `Session` object, whose `get` and `set` methods trigger change events. Two `Deps.autorun` callbacks log session values, and a `stop()` method halts one computation after a condition is met. The example runs asynchronous timers to illustrate re-execution and manual invalidation.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-0962fe60586644cf90d6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
