eslint-plugin-ternaries

library1.1.0jsnpmunverified

An ESLint plugin that provides rules specifically for controlling the use of ternary expressions in JavaScript. The current stable version is 1.1.0, which adds the no-empty-ternary rule to complement the existing no-null-ternary rule. This plugin is designed for teams that want to enforce coding standards around ternaries, such as disallowing null or empty string values in ternary branches. It is a lightweight plugin with no additional dependencies besides ESLint itself.

Plugin

✓ // .eslintrc: { "plugins": ["ternaries"] }

✗ // npm install eslint-plugin-ternaries --save-dev (forgetting to add to plugins)

The plugin is registered in ESLint config, not imported in code.

no-null-ternary

✓ // .eslintrc: { "rules": { "ternaries/no-null-ternary": "error" } }

✗ { "rules": { "no-null-ternary": "error" } }

Rules must be prefixed with the plugin name 'ternaries/'.

no-empty-ternary

✓ // .eslintrc: { "rules": { "ternaries/no-empty-ternary": "warn" } }

✗ { "rules": { "ternaries/no-empty-ternary": "error", "ternaries/no-null-ternary": 2 } }

Severity levels: 0=off, 1=warn, 2=error. Common mistake is using numbers or strings incorrectly.

Shows installation, configuration in .eslintrc, and example violations.

// Step 1: Install ESLint and the plugin npm install eslint --save-dev npm install eslint-plugin-ternaries --save-dev // Step 2: Create .eslintrc.json { "plugins": ["ternaries"], "rules": { "ternaries/no-null-ternary": "error", "ternaries/no-empty-ternary": "warn" } } // Step 3: Test with a file const x = condition ? null : 1; // Error: ternaries/no-null-ternary const y = condition ? '' : 2; // Warning: ternaries/no-empty-ternary
