VSCode removing React from imports on save - visual-studio-code

Question

after switching to vscode 1.68.1
every time on saving the file its automatically removing the React from the import
at first i though this could be an eslint issue as i am using eslint for formatting but after removing eslint plugin issue remains the same
here is my settings.json
{
"eslint.alwaysShowStatus": true,
"editor.formatOnSave": true,
"files.eol": "\r\n",
"editor.codeActionsOnSave": {
"source.fixAll": true,
"source.organizeImports": true
},
"editor.defaultFormatter": "dbaeumer.vscode-eslint",
"prettier.arrowParens": "avoid",
"prettier.embeddedLanguageFormatting": "off",
"prettier.enable": false,
"eslint.format.enable": false,
"[css]": {
"editor.defaultFormatter": "aeschli.vscode-css-formatter"
},
"[html]": {
"editor.defaultFormatter": "vscode.html-language-features"
},
"[json]": {
"editor.defaultFormatter": "vscode.json-language-features"
},
"[jsonc]": {
"editor.defaultFormatter": "vscode.json-language-features"
}
}
and here is the .eslintrc
module.exports = {
"env": {
"browser": true,
"es6": true
},
"extends": "airbnb",
"globals": {
"Atomics": "readonly",
"SharedArrayBuffer": "readonly"
},
"parserOptions": {
"ecmaFeatures": {
"jsx": true
},
"ecmaVersion": 2018,
"sourceType": "module"
},
"plugins": [
"react", "react-hooks"
],
"rules": {
"linebreak-style": ["error", "windows"],
"react/forbid-prop-types": 0,
"react/prop-types": 0,
"max-len": ["error", { "code": 220 }]
},
"settings": {
"import/resolver": {
"node": {
"moduleDirectory": ["node_modules", "src/"]
}
}
}
};

Answer 1

Try adding these rules in eslintrc:
{
"rules": {
"react/jsx-uses-react": 0,
"react/react-in-jsx-scope": 0
}
}
OR
Try adding "jsx": "react" to your jsconfig:
{
"compilerOptions": {
"baseUrl": ".",
"jsx": "react",
"paths": {
"*": ["*", "src/*"]
}
}
}
This helps VS-Code understand that React is implicitly referenced by the jsx elements in your file.
I had the same problem in multiple projects, after adding these rules, solves the problem for me.

Answer 2

VS Code expects that every project declares a tsconfig.json or jsconfig.json and if none is provided, it defaults it to
{
"compilerOptions": {
"jsx": "react"
}
}
This effectively means that if you have React imports in your code, they will be preserved.
To adopt the latest react 17+ standard with the _jsx transform, the environment type needs to be react-jsx.
{
"compilerOptions": {
"jsx": "react-jsx"
}
}

Answer 3

{
// ...
"rules": {
// ...
"react/jsx-uses-react": "on",
"react/react-in-jsx-scope": "on"
}
}
Add these rules to your eslint config

Answer 4

add type on your tsx file, to prevent removed automatically by vscode
import React from 'react';
type _react = typeof React
.eslint
{
rules: {
'react/jsx-uses-react': 0, // ignore validation must include react scope in jsx/tsx
'react/react-in-jsx-scope': 0, // ignore validation must include react scope in jsx/tsx
'no-unused-vars': 'off', // disable default eslint unused variable
'#typescript-eslint/no-unused-vars': [ // ignore validation variable with prefix _
'warn',
{
argsIgnorePattern: '^_',
varsIgnorePattern: '^_',
caughtErrorsIgnorePattern: '^_'
}
]
}
}

I also had the same problem, when removing the extensions I found it was vscode, downgrading to version 1.67.2 solved it

Answer 6

Try removing the "source.organizeImports": true line from your settings, or setting it to false.
I think VS Code thinks the React import is unnecessary because its only used implicitly (which can be a problem if your compiler requires an explicit import to bundle correctly).
