When AngularJS throws the "$digest already in progress" error, the UI can freeze or show incomplete updates. This guide walks through symptom recognition, root‑cause analysis, ordered checks, fixes, and escalation criteria to help you diagnose and resolve the issue safely.
Use AngularJS :: one-time binding to remove watchers for stable template values and shorten digest cycles.
Large ng-repeat lists can create thousands of digest watchers. AngularJS one-time bindings remove watchers once values stabilize, but only for read-only data. Here is how to apply them safely and verify the impact.
Large AngularJS 1.x lists lag because every digest re-evaluates thousands of watchers. One-time binding (::) deregisters watchers for static data — here's how it works, a worked ng-repeat example, and the staleness trade-off.
Understand how ng-model implements two-way data binding in AngularJS 1.x to synchronize the View and Model, and learn how to manage the performance impact of the digest cycle.
Use AngularJS one-time binding (::) to drop watcher count and speed up digest cycles in large lists.
AngularJS 1.3+ one-time bindings (::) deregister watchers after first render, cutting digest-cycle time in large lists. A practical guide to applying, verifying, and safely reverting them.
The AngularJS infdig error means a watch never stabilizes across digest passes. Learn to read the watch list, isolate the offender, and apply the right fix — without masking it via digestTtl().
AngularJS digest cost scales with watcher count. One-time binding (::) in 1.3+ lets static bindings deregister after first render — here's a worked example, the async trap, and how to measure the win.
