Shared ESLint configs for Node, Web, React Native, and Expo projects.

This is a friendly fork of eslint-config-universe from expo folks, as we want to configure special rules for our projects.

yarn add --dev eslint-config-bambi

You will also need to install eslint and prettier:

yarn add --dev eslint prettier

Import this config into your own ESLint configuration using the extends option. ESLint checks both package.json and .eslintrc.* files for its configuration:

{
  "eslintConfig": {
    // Choose from bambi/native, bambi/node, bambi/web
    "extends": "bambi"
  }
}

module.exports = {
  extends: 'bambi',
};

If you would like to customize the Prettier settings, create a file named .prettierrc in your project directory. This file must declare a Prettier configuration like this:

{
  "printWidth": 100,
  "tabWidth": 2,
  "singleQuote": true,
  "jsxBracketSameLine": true,
  "trailingComma": "es5"
}

There are several configs for different platforms. They are:

• bambi: the basic config for JavaScript projects for which there isn't a more specific config
• bambi/native: the config for React Native projects, including Expo projects, with support for React and JSX
• bambi/web: the config for code that runs in web browsers, with support for React and JSX
• bambi/node: the config for code that runs in Node

For an Expo project, your configuration might look like this:

"eslintConfig": {
  "extends": "bambi/native"
}

You also can extend multiple configs, which is useful for projects that span several platforms:

"eslintConfig": {
  "extends": ["bambi/node", "bambi/web"]
}

This config is designed to mark severe problems (ex: syntax errors) as errors and stylistic issues as warnings. This lets your team apply policies like, "make sure a commit has no errors but ignore warnings if the commit didn't introduce them."

It's also designed to be a more lenient config for teams who are stronger at decision-making and have a culture of osmotically learning coding guidelines and benefit more from flexibility than rigid rules.
