JSX is restricted in files using the '.tsx' extension according to eslint rules (react/jsx-filename-extension)

When working in a .tsx file, why does eslint flag the following issue:

The use of JSX is not permitted in files with the extension '.tsx' (eslint react/jsx-filename-extension)

What steps can I take to adjust the eslint configuration and address this warning?

Answer №1

To ensure ESLint is satisfied with JSX in your TypeScript files, consider adjusting the settings of the react/jsx-filename-extension rule within your .eslintrc.js:

rules:  {
  'react/jsx-filename-extension': [2, { 'extensions': ['.js', '.jsx', '.ts', '.tsx'] }],
},

Answer №2

To include TypeScript files in your eslint configuration, make sure to add the following rule within the rules section:

"rules": {
  "react/jsx-filename-extension": [1, { "extensions": [".tsx", ".ts"] }]
}
