Sonar Rule: typescript:S4323 — MINOR Repeating the same union type inline in multiple places leads to inconsistency and makes refactoring harder. Extracting it into a named type alias improves readability and maintainability. Affected file packages/ui/src/xml-schema-ts/facet/XmlSchemaFacet.ts:5 Proposed fix // Before: function process(value: string | number | boolean) { ... } function validate(value: string | number | boolean) { ... } // After: type FacetValue = string | number | boolean; function process(value: FacetValue) { ... } function validate(value: FacetValue) { ... } References SonarQube Rule S4323

Sonar Rule: typescript:S7780 — MINOR When a string contains many backslashes (e.g. regex-like patterns in template strings), String.raw avoids the need for double-escaping and makes the string literal easier to read. Affected file packages/ui/src/services/xpath/2.0/xpath-2.0-parser.ts:11 Proposed fix // Before: const pattern = "(\\w+)|-|_|\\."; // After: const pattern = String.raw`(\w+)|-|_|\.`; References SonarQube Rule S7780 MDN — String.raw()

Sonar Rule: typescript:S3626 — MINOR A return, break, or continue statement that is the last statement before the natural end of a block is redundant and should be removed. Affected file packages/ui/src/models/camel/integration-resource.ts:18 Proposed fix // Before (redundant return at end of function): function doSomething() { processData(); return; // redundant } // After: function doSomething() { processData(); } References SonarQube Rule S3626

Sonar Rule: typescript:S6606 — MINOR The pattern x = x ?? value or if (x == null) x = value can be replaced with the more concise nullish coalescing assignment operator x ??= value.
