## Usage

Adapt the content of your `tslint.json` file as follows:

```text
{
	"extends": ["tslint:latest", "whatever config", "@nationalbankbelgium/code-style/tslint/6.1.x"],
	"rules": {
		// your rules
	}
}
```

## Recommended Additional Configs

We highly recommend using [Prettier](https://prettier.io) to handle all the formatting hassle in your codebase.
In fact `code-style` also provides a Prettier config you can use: [code style - Prettier](../prettier/README.md).

In this case, when using Prettier you would also need an additional TSLint configuration preset: [tslint-config-prettier](https://github.com/prettier/tslint-config-prettier)
to avoid conflicts with this `code-style/tslint` config regarding some formatting related rules.

So make sure to use those configs in your `tslint.json` as follows:

```text
{
	"extends": ["tslint:latest", "whatever config", "@nationalbankbelgium/code-style/tslint/6.1.x", "tslint-config-prettier"],
	"rules": {
		// your rules
	}
}
```

**IMPORTANT: notice that the `tslint-config-prettier` preset is used at the end of the `extends` list. The reason for this is that such preset
overrides any formatting TSLint rule that was enabled by the precedent presets that may conflict with Prettier.**
