# eslint-plugin-undef-init
|
|
|
|
Always initialize variables declarations. Instead of naked declarations, set it to undefined.
|
|
|
|
## Installation
|
|
|
|
You'll first need to install [ESLint](http://eslint.org):
|
|
|
|
```
|
|
$ npm i eslint --save-dev
|
|
```
|
|
|
|
Next, install `eslint-plugin-undef-init`:
|
|
|
|
```
|
|
$ npm install eslint-plugin-undef-init --save-dev
|
|
```
|
|
|
|
**Note:** If you installed ESLint globally (using the `-g` flag) then you must also install `eslint-plugin-undef-init` globally.
|
|
|
|
## Usage
|
|
|
|
Add `undef-init` to the plugins section of your `.eslintrc` configuration file. You can omit the `eslint-plugin-` prefix:
|
|
|
|
```json
|
|
{
|
|
"plugins": [
|
|
"undef-init"
|
|
]
|
|
}
|
|
```
|
|
|
|
|
|
Then configure the rules you want to use under the rules section.
|
|
|
|
```json
|
|
{
|
|
"rules": {
|
|
"undef-init/rule-name": 2
|
|
}
|
|
}
|
|
```
|
|
|
