After setting up a new React TypeScript project and installing ESLint with the config prompt, I specified that my project utilizes React and TypeScript. However, I am encountering duplicate style warnings from both TypeScript and ESLint. How can I prevent these overlapping warnings? Do I need to manually edit ESLint rules or are there pre-made .eslintrc configurations available to address this issue?
If you want to silence the warning from ESLint, one way to do it is by disabling the rule in your configuration file such as .eslintrc.js or .eslintrc.json. Here's an example of how you can do it:
..
rules: {
'no-unused-vars': 'off',
'@typescript-eslint/no-unused-vars': 'off',
..
}
..
Alternatively, you could choose to disable the TypeScript warning instead, since the ESLint rule offers more flexibility. To disable it in TypeScript, adjust the compiler options in your tsconfig.json like this:
..
"compilerOptions": {
"noUnusedLocals": false,
"noUnusedParameters": false,
..
}
..
You can also customize the ESLint rule further, for example by excluding identifiers starting with a _. This can be done by modifying your .eslintrc.js file as shown below:
..
rules: {
'no-unused-vars': 'off',
'@typescript-eslint/no-unused-vars':
['warn', {argsIgnorePattern: '^_', varsIgnorePattern: '^_'}],
..
}
It's worth noting that the base rule no-unused-vars is advised to always be disabled according to the
@typescript-eslint/no-unused-vars@typescript-eslint/no-unused-varsno-unused-vars documentation, as they share the same options.
