Eslint best linting tool for javascript code
Posted By : Parveen Kumar Yadav | 26-Sep-2017
As we know that Linting is an important part of daily workflow. Eslint is a great linting tool for your ECMAScript/JavaScript code . You can use the rules defined on it or even though you can create your own custom rules, as i have used this tool in one of my project. Install locally via npm:-
npm install eslint --save-dev
after that setup a configuration file:-
./node_modules/.bin/eslint --init
after that you can run it easily via:-
$ ./node_modules/.bin/eslint yourfile.js
you can install it globally via:-
$ npm install -g eslint
setup a configuration file:-
$ eslint --init
run directly via:-
$ eslint yourfile.js
After installation you can configure your rules in configuration file:- In the .eslintrc file
{
"rules": {
"semi": ["error", "always"],
"quotes": ["error", "double"]
}
}
You can also create your custom rules at runtime a great feature of Eslint if you want to create like:-
1)You need to place all runtime rules in the same directory
2)You need to create a configuration file and need to define your rule Id error level under rules key.
3)Run the command over terminal i.e. --rulesdir (this is an option to specify location of your rules)
Hope it would helps !
