eslint/rules/complexity

Complexity: Size and complexity limits: lines, statements, nesting, cognitive complexity. Rules of ESLint, typescript-eslint and SonarJS (the Sonar way profile of SonarQube) on this subject, every rule listed; the TypeScript rules apply to TypeScript files only.

9 rules, 3 on. Source: lint/eslint/rules/complexity.mjs.

Rule	Setting	Files	What it checks	Why
complexity	off	JS + TS	Enforce a maximum cyclomatic complexity allowed in a program	Off: replaced by sonarjs/cognitive-complexity, like SonarQube.
max-depth	off	JS + TS	Enforce a maximum depth that blocks can be nested	Off: replaced by sonarjs/nested-control-flow, like SonarQube.
max-lines	off	JS + TS	Enforce a maximum number of lines per file	Off: replaced by sonarjs/max-lines, like SonarQube.
max-statements	off	JS + TS	Enforce a maximum number of statements allowed in function blocks	Off: no SonarQube equivalent.
sonarjs/max-lines	warn, {"maximum":200}	JS + TS	Files should not have too many lines of code	Custom: outside Sonar way; replaces the core max-lines, like SonarQube. Warn: a size limit: a justified exception (a data table, a state machine) may pass.
sonarjs/nested-control-flow	warn	JS + TS	Control flow statements "if", "for", "while", "switch" and "try" should not be nested too deeply	Custom: outside Sonar way; replaces the core max-depth, like SonarQube. Warn: a size limit: a justified exception (a data table, a state machine) may pass.
sonarjs/expression-complexity	off	JS + TS	Expressions should not be too complex	Off: not in the Sonar way profile of SonarQube.
sonarjs/cognitive-complexity	warn	JS + TS	Cognitive Complexity of functions should not be too high	Sonar way; replaces the core complexity, like SonarQube. Warn: a size limit: a justified exception (a data table, a state machine) may pass.
sonarjs/cyclomatic-complexity	off	JS + TS	Cyclomatic Complexity of functions should not be too high	Off: not in the Sonar way profile of SonarQube.
