Eslint rules concerning ternaries
Installation
You'll first need to install ESLint:
$ npm i eslint --save-dev
Next, install eslint-plugin-ternaries
:
$ npm install eslint-plugin-ternaries --save-dev
Note: If you installed ESLint globally (using the -g
flag) then you must also install eslint-plugin-ternaries
globally.
Usage
Add ternaries
to the plugins section of your .eslintrc
configuration file. You can omit the eslint-plugin-
prefix:
{ "plugins": [+ "ternaries" ]}
Then configure the rules you want to use under the rules section.
{ "rules": {+ "ternaries/no-null-ternary": 2,+ "ternaries/no-empty-ternary": 2 }}
Supported Rules
- no-null-ternary - Disallows ternaries with null as either the consequent or alternate condition.
- no-empty-ternary - Disallows ternaries that have '' or "" as either condition.
