I recently started using vscode for react development and am running into an issue currently.
Given the following little code snippet:
export default class foo extends React.Component {
render() {
return <div>Hello World</div>;
}
}
vscode underlines React since the name is not defined. When trying to apply a quick fix (alt+enter mapped to editor.action.quickFix) vscode recommends the following:
import * as React from "../../../Users/daniel/Library/Caches/typescript/2.4/node_modules/#types/react"
I have react installed in the current working directory within the node_modules folder (installed through npm). Why does vscode not recommend me including react from there and instead wants me to include a typings file?
Expected recommendation:
import * as React from "react";
My jsconfig.json
{
"compilerOptions": {
"target": "ES6",
"checkJs": true,
"module": "commonjs",
"allowSyntheticDefaultImports": true,
"baseUrl": "./",
},
"exclude": [
"dist"
],
"include": [
"./**/*.js"
]
}
Folder structure:
/
node_modules/
react/
...
jsconfig.json
packacke.json
package-lock.json
test.js
Is there anything wrong with my setup or is there anything else I need to configure before it will work as expected? I have tried reloading the workspace / restarting vscode multiple times so far.

I am working on a react native project and I want to include a test but I am facing an issue with paths
here is my configuration of tsconfig.json
"paths": {
"#/*": ["./src/*"],
"#config": ["./config/index.ts"]
},
and for jest.config.js
moduleNameMapper: {
"//(.*)/": "./src/*",
},
but I am always getting an issue with importing modules in testing for example
import {core} from '#core'
it always said not found
I am new to pnpm workspaces and am trying to resolve the following issue.
My demo project:
root
packages
common-ui
main-lib
common-ui is a Vite based package containing some Vue components that can be reused by other packages, in my example it's being used by main-lib.
"dependencies": {
"ui-common": "workspace:*"
},
common-ui is referencing an index.ts inside its package.json
"main": "index.ts",
index.ts is exporting my Vue components:
...
export { default as Heading } from './components/Heading/Heading.vue';
...
Now I am able to import those components inside main-lib:
import { Heading } from 'common-ui'
This all works fine but I would also like to be able to publish my library to the npm registry. As common-ui is using the Vite, it's possible to build in library mode: https://vitejs.dev/guide/build.html#library-mode. My package inside common-ui will need to change to:
{
"name": "common-ui",
"files": ["dist"],
"main": "./dist/common-ui.umd.js",
"module": "./dist/common-ui.es.js",
"exports": {
".": {
"import": "./dist/common-ui.es.js",
"require": "./dist/common-ui.umd.js"
}
}
}
main is not referencing index.ts anymore but a dist folder that only gets updated when the vite command is ran. Is there a way for me to support both publishing/versioning and referencing the actual source code from inside main-lib?
I've taken a quick look at Rush.js but I am not sure if provides a solution and I want to be sure before I continue on that path.
General jist:
import Image from '#/assets/default-profile-picture.svg'
//ERROR: Cannot find module '#/assets/default-profile-picture.svg'.Vetur(2307)
I have spent the better part of today trying to find a solution to this. I know there are a lot of other posts like this one, but they are all outdated (all over a year old).
I've just generated a clean Vue CLI app, and still have the same issue.
I'm using Vue CLI Version 4.2.3, and just attempted using Vue CLI Version 4.3.1, but ran into the same issue.
I have checked that the file is in assets.
I have checked that the filename is spelled correctly.
I have a feeling this is a webpack issue, as require() would not work when called using typescript.
I have tried creating vue.config.js and manually setting the path for assets.
Project setup configuration:
Features: Babel, TS, Router, ESLint
not class-style syntax
Babel used alongside Typescript
No history mode for router
eslint with error prevention only
Lint on save
Configs placed in package.json.
Error in Component.vue
<script lang="ts">
import Vue from 'vue'

import Image from '#/assets/default-profile-picture.svg'

components: {
},
props: [
'employeeImage',
'employeeName',

return {

if (this.employeeImage === '') {
console.log('employee image empty: ' + this.employeeImage)
return '#/assets/default-profile-picture.svg'
} else {
console.log('employee image set: ' + this.employeeImage)
return this.employeeImage
}
}
}
})
</script>

What am I doing wrong?
Thanks in advance!
Please keep this in mind, that this answer is not a solution but more like a work-around for this issue by the time this question has been asked/answered for vue-svg-loader(#vue/cli Version: 4.2.3 and 4.3.1).
You can use absolute path instead of using # to reference the file when you want to import .vue components. Here is an example:
Instead of this:
Read more about this issue and any possible solutions on official repository for this issue on GitHub:
Typescript Cannot find module '#/assets/svg/register.svg?inline' #92
Typescript does not support svg files.
Create a svg.d.ts file in your project source folder with the following content:
declare module '*.svg';
and restart your editor
I have followed the steps outlined in the VS Code documentation for getting Intellisense working for React Native by installing typings for React Native. Now, what do I need to do to get autocomplete working? For instance, if I type <Text>, I would like to see an automatic closing of that tag. What am I missing here? This seems like it shuld work out of the box.
To enable IntelliSense (autocomplete) you have to install the official React Native Tools extension.
Installation
Open Command Palette by pressing F1, type ext install and press Enter, then look for React Native Tools extension.
Create a jsconfig.json file
You should create a jsconfig.json file in you root directory. It can be empty but must be present. The presence of such a file in a directory indicates that the directory is the root of a JavaScript project.
(Optional)
The file itself can optionally list the files belonging to the project, the files to be excluded from the project, as well as compiler options.
{
"compilerOptions": {
"target": "ES6",
"module": "commonjs",
"allowSyntheticDefaultImports": true
},
"exclude": [
"node_modules"
]
}
You can find more at https://code.visualstudio.com/docs/languages/javascript#_javascript-projects-jsconfigjson
Create a .babelrc file for ReactNative Packger transformer (optional, if you want to use TypeScript)
You should create a .babelrc file with sourceMaps = true and "presets": [ "react-native" ] for better source-mapping support. (required if you want TypeScript support).
{
"presets": [
"react-native" // this is required for debugging with react-native/packager/transformer
],
"plugins": [],
"sourceMaps": true // must be true react-native/packager/transformer using with node-module-debug
// because of some bugs from vscode-node-debug & vscode-react-native, "sourceMaps" cannot be "inline" or "both"
}
Install typings for React Native (optional)
To get IntelliSense for React Native, run npm install typings -g and then typings install dt~react-native --global in your terminal.
Hope this helps!!
React Native Tools in VSCode can't help you close the Tag after you typed<Text>,you can try to install Auto Close Tag and Auto Rename Tag
In my case, I have to copy jsconfig.json to tsconfig.json, close Visual Code and reopen it. Then it works properly.
jsconfig.json
{
"compilerOptions": {
"allowSyntheticDefaultImports": true
},
"exclude": [
"node_modules"
]
}
tsconfig.json
{
"compilerOptions": {
"allowJs": true,
"allowSyntheticDefaultImports": true
},
"exclude": [
"node_modules"
]
}
I am also not getting any IntelliSense and also package auto-import is not working. Since I am not using Typescript, deleting the tsconfig.json helped me.
Take backup of your tsconfig.json file first
In my case, I've already installed many react-native extensions for autoSuggestion and another helper extension, e.g. "React Native Tools", and "React-Native/React/Redux snippets for es6/es7"
Issues:
autoSuggestion keywords not coming while typing.
command(in IOS) + click not letting me to jump on the target files.
Recently I have seen in VS Code editor for new React-native applications autoSuggestion not working.
Steps I have followed to solve:
Go to Extensions
Search for React or React-native
Remove the installed extension
Reload it.
When I'm launching my project using React-Native default packager, I have this error: Unexpected token on this line:
static propTypes = {
/// ...
};
I took a look on React-Native issues on GitHub, but I didn't find a solution.
Any suggestion?
React-Native packager use Babel for transfer ES6 and ES7, but NOT ALL features. The enable list is here. In your case, class-props is not enabled by default in RN packager. You can use Babel to compiler your code before packager, or just enable it in the packager setting. See this official doc for more information.
Try appending your propTypes to your class:
var MyClass extends React.Component {
....
}
MyClass.propTypes = {
.... /* enter proptypes here */
}
After #Fomahaut answer, I keep looking on Facebook's GitHub repository and found this issue: https://github.com/facebook/react-native/issues/2182
Create a .babelrc file at the project's root directory
Add more rules to Babel
Example:
{
"retainLines": true,
"compact": true,
"comments": false,
"whitelist": [
"es6.arrowFunctions",
"es6.blockScoping",
"es6.classes",
"es6.constants",
"es6.destructuring",
"es6.forOf",
"es6.modules",
"es6.parameters",
"es6.properties.computed",
"es6.properties.shorthand",
"es6.spread",
"es6.tailCall",
"es6.templateLiterals",
"es6.regex.unicode",
"es6.regex.sticky",
"es7.asyncFunctions",
"es7.classProperties",
"es7.comprehensions",
"es7.decorators",
"es7.exponentiationOperator",
"es7.exportExtensions",
"es7.functionBind",
"es7.objectRestSpread",
"es7.trailingFunctionCommas",
"regenerator",
"flow",
"react",
"react.displayName"
],
"sourceMaps": false
}
According to this answer, you need to install a plugin for class properties as of Babel 6.
As of Babel 6, you now need the transform-class-properties plugin to
support class properties.
Steps:
Run this: npm install babel-plugin-transform-class-properties
Add this to your .babelrc: "plugins": ["transform-class-properties"]
(Note, it's a plugin, not a transform; so don't put it in the "presets" list.)
Worked for me.
Install the stage-0 Babel preset (npm i --save-dev babel-preset-stage-0) and add it to .babelrc file's presets section, e.g.:
{ "presets": ["react", "es2015", "babel-preset-stage-0"] }
See if that helps:
$ npm install babel-plugin-transform-decorators
navigate to /<your project root>/node_modules/react-native/packager/react-packager/.babelrc
Add "transform-decorators" to this list:
{
"retainLines": true,
"compact": true,
"comments": false,
"plugins": [
"syntax-async-functions",
"syntax-class-properties",
"syntax-trailing-function-commas",
"transform-class-properties",
"transform-es2015-arrow-functions",
"transform-es2015-block-scoping",
"transform-es2015-classes",
"transform-es2015-computed-properties",
"transform-es2015-constants",
"transform-es2015-destructuring",
["transform-es2015-modules-commonjs", {"strict": false, "allowTopLevelThis": true}],
"transform-es2015-parameters",
"transform-es2015-shorthand-properties",
"transform-es2015-spread",
"transform-es2015-template-literals",
"transform-flow-strip-types",
"transform-object-assign",
"transform-object-rest-spread",
"transform-react-display-name",
"transform-react-jsx",
"transform-regenerator",
"transform-es2015-for-of",

],
"sourceMaps": false
}
