  • .vscode/extensions.json:

    {
      "recommendations": [
          "dbaeumer.vscode-eslint"
      ]
    }

  • .vscode/tasks.json:

    {
      "version": "2.0.0",
      "tasks": [

            "typescriptreact"
        ]
    }

Contributing

• index.js is eslint config for JavaScript projects.
• ts.js is eslint config for TypeScript projects; and extends from index.js.

• If @typescript-eslint has an override rule of an eslint rule; first make sure you turn off the eslint rule in ts.js.

  {
    quotes: "off",
    '@typescript-eslint/quotes': [
      'error',
      'single',
      {
          avoidEscape: true,
          allowTemplateLiterals: true
      }
    ],
  }

• If a rule works the same way for both JavaScript and TypeScript, add the rule's value (configuration) in _common.js and reference in both index.js and ts.js.

  // _common.js
  {
    QUOTES: [
      'error',
      'single',
      {
        avoidEscape: true,
        allowTemplateLiterals: true
      }
    ],
    // ...
  }
  
  // index.js
  {
    quotes: common.QUOTES,
    // ...
  }
  
  // ts.js
  {
    quotes: 'off',
    '@typescript-eslint/quotes': common.QUOTES,
    // ...
  }
