# ESLint rules for TSLint
|
|
## Improve your TSLint with the missing ESLint Rules
|
|
You want to code in TypeScript but miss all the rules available in ESLint?
|
|
Now you can combine both worlds by using this TSLint plugin!
|
|
|
## Usage
|
|
### Install from NPM to your Dev Dependencies
|
|
```console
|
npm install --save-dev tslint-eslint-rules
|
```
|
|
### Or install from Yarn to your Dev Dependencies
|
|
```console
|
yarn add tslint-eslint-rules --dev
|
```
|
|
### Configure TSLint to use `tslint-eslint-rules`:
|
|
In your `tslint.json` file, extend this package, e.g:
|
|
```json
|
{
|
"extends": [
|
"tslint-eslint-rules"
|
],
|
"rules": {
|
"no-constant-condition": true
|
}
|
}
|
```
|
|
You can also extend other tslint config packages to combine this plugin with other community custom rules.
|
|
|
### Configure your rules
|
|
In your `tslint.json` file, insert the rules as described below.
|
|
|
## Rules (copied from the [ESLint website](http://eslint.org/docs/rules/))
|
|
The following tables shows all the existing ESLint rules and the similar rules available in TSLint.
|
Please refer to the following icons as they provide the status of the rule.
|
|
| Icon | Description |

| :--- | :-- |
|
| :no_entry_sign: | The rule is not applicable to Typescript. |
|
| :ballot_box_with_check: | The rule is provided natively by [TSLint](http://palantir.github.io/tslint/rules/). |
|
| :white_check_mark: | The rule is available via tslint-eslint-rules. |
|
| :x: | The rule is currently unavailable. |
