eslint-config-signavio/CHANGELOG.md

This package provides the agreed-upon set of JavaScript linting rules for all JavaScript projects at Signavio. The rule set is based upon the linting rules employed at [airbnb](https://github.com/airbnb/javascript/tree/master/packages/eslint-config-airbnb

# v3.2.0

Upgrade `prettier` to `v1.6.1` to allow the usage of the `prettier.config.js` file.
To use this configuration in your project add the following script to your `package.json`:

```json
{
    "scripts": {
        "prettier": "prettier --write --config ./node_modules/eslint-config-signavio/prettier.config.js **/*.js"
    }
}
```

# v3.0.0

Introduction of [`prettier`](https://github.com/prettier/prettier) to the config.
At the same time update the base for this ruleset [eslint-config-airbnb](https://github.com/airbnb/javascript)

## Breaking changes:

- `babel-parser` was removed as `eslint` can handle most of ES2017 code. If you do need `babel-eslint` for further transforms keep in mind to add it to your code

## The changes are smaller than they appear:

### One environment was removed:

- Remove `mocha` from `env` because this belongs into [eslint-config-signavio-test](https://github.com/signavio/eslint-config-signavio-test)

### Some rules are changed:

- [`no-cond-assign`](http://eslint.org/docs/rules/no-cond-assign) now follows the `airbnb` style to always be an error
- [`import/no-duplicates`](https://github.com/benmosher/eslint-plugin-import/blob/master/docs/rules/no-duplicates.md) error instead of warning
- [`import/prefer-default-export`](https://github.com/benmosher/eslint-plugin-import/blob/master/docs/rules/prefer-default-export.md) error instead of warning
- [`react/prop-types`](https://github.com/yannickcr/eslint-plugin-react/blob/master/docs/rules/prop-types.md) error instead of warning

### Some rules are now checked by [eslint-plugin-prettier](https://github.com/prettier/eslint-plugin-prettier)

### Some rules are special (see [eslint-config-prettier#special-rules](https://github.com/prettier/eslint-config-prettier#special-rules))

- `curly` `'error': 'multi-line'` because it will enforce braces if a block has multiple lines
  This will only trigger after `prettier` but is still considered useful
- `max-len` `'error'` to give hints about strings that might need manual splitting
- `no-tabs` We don't want any tabs in our code
