From dd30aad11d9d56fb7fb79110bc46983161dbb387 Mon Sep 17 00:00:00 2001 From: Daniel Griesser Date: Tue, 17 Mar 2026 17:39:59 +0100 Subject: [PATCH 1/3] refactor(core): Simplify core utility functions for smaller bundle MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A collection of small, safe simplifications across core utilities: - envelope.ts: Slim ITEM_TYPE_TO_DATA_CATEGORY_MAP by removing 7 self-mapping entries (e.g. session→session). Use a fallback to the type name itself. - object.ts: Replace getOwnProperties manual for-in+hasOwnProperty loop with Object.fromEntries(Object.entries(obj)). Use shorthand value in addNonEnumerableProperty. - baggage.ts: Use .startsWith() instead of .match(regex) for prefix check. - browser.ts: Inline allowedAttrs array literal directly in for-of loop. - eventFilters.ts: Convert verbose DEFAULT_IGNORE_ERRORS string literals to shorter regex patterns with equivalent matching behavior. All changes are behavior-preserving. Combined saves ~80 bytes gzipped.
