module.exports = {
  parserOptions: {
    project: './tsconfig.json',
    babelOptions: {
      configFile: './babel.config.js'
    }
  },
  extends: [
    '@hastom/eslint-config/typescript-mixed',
    '@hastom/eslint-config/react',
  ]
};

// pure typescript
module.exports = {
  parserOptions: {
    project: './tsconfig.json',
  },
  extends: [
    '@hastom/eslint-config/typescript-pure',
  ]
};

// pure javascript
module.exports = {
  parserOptions: {
    babelOptions: {
      configFile: './babel.config.js'
    }
  },
  extends: [
    '@hastom/eslint-config/base',
  ]
};

Extend @hastom/eslint-config/typescript-mixed if your project uses typescript AND javascript

Extend @hastom/eslint-config/typescript-pure if your project uses ONLY typescript

Extend @hastom/eslint-config/base if your project uses ONLY javascript

Extend @hastom/eslint-config/react if your project uses React

If typescript-mixed or base configs are extended you MUST install @babel/core package to support @babel/eslint-parser plugin. Also, path to babel config file should be set at parserOptions.babelOptions.configFile

If typescript-mixed or typescript-pure configs are extended parserOptions.project MUST be set to match tsconfig.json file. All linted files MUST be included or listed in tsconfig.json.
