Install
eslint-plugin-no-use-extend-native
ESLint plugin to prevent use of extended native objects
Uses Sindre Sorhus's proto-props
Install
First, install ESLint via
npm install --save-dev eslint
Then install eslint-plugin-no-use-extend-native
npm install --save-dev eslint-plugin-no-use-extend-native
Usage
In your .eslintrc
file add the plugin as such:
{
plugins: [
'no-use-extend-native'
]
}
To modify the single rule, no-use-extend-native
, add the rule to your .eslintrc.*
as such:
{
plugins: [
'no-use-extend-native'
],
rules: {
'no-use-extend-native/no-use-extend-native': 1
}
}
The default value is 2
.
If you want the default, you can also just use the following instead of
all of the above:
{
extends: ['plugin:no-use-extend-native/recommended']
}
With this plugin enabled, ESLint will find issues with using extended native objects:
const colors = require('colors');
console.log('unicorn'.green);
// => ESLint will give an error stating 'Avoid using extended native objects'
[].customFunction();
// => ESLint will give an error stating 'Avoid using extended native objects'
More examples can be seen in the tests.
Usage with no-extend-native
ESLint's no-extend-native
rule verifies code is not modifying a native prototype. e.g., with the no-extend-native
rule enabled, the following lines are each considered incorrect:
String.prototype.shortHash = function() { return this.substring(0, 7); };
Object.defineProperty(Array.prototype, "times", { value: 999 });
no-use-extend-native
verifies code is not using a non-native prototype. e.g., with the no-use-extend-native
plugin enabled, the following line is considered incorrect:
"50bda47b09923e045759db8e8dd01a0bacd97370".shortHash() === "50bda47";
The no-use-extend-native
plugin is designed to work with ESLint's no-extend-native
rule. no-extend-native
ensures that native prototypes aren't extended, and should a third party library extend them, no-use-extend-native
ensures those changes aren't depended upon.
