Node modules won't import in my Vue.js project - javascript

I'm trying to import a node module installed through NPM inside a Vue.js single file component. Every time, whatever the module is, it won't work and throw an error such as These depedencies were not found. I'm following the install instructions right (at least I think) but I guess I'm missing something.
Example :
Trying to install the swiper.js module.
I did the NPM install in the right folder, then in the component where I want to use it I added the following lines such as explained on their website :
import { Swiper, SwiperSlide } from 'swiper/vue';
import 'swiper/css';
And when I'm starting my server I get this error :
These dependencies were not found:
* swiper/css in ./node_modules/cache-loader/dist/cjs.js??ref--12-0!./node_modules/babel-loader/lib!./node_modules/cache-loader/dist/cjs.js??ref--0-0!./node_modules/vue-loader/lib??vue-loader-options!./src/components/ProductCarousel.vue?vue&type=script&lang=js&
* swiper/vue in ./node_modules/cache-loader/dist/cjs.js??ref--12-0!./node_modules/babel-loader/lib!./node_modules/cache-loader/dist/cjs.js??ref--0-0!./node_modules/vue-loader/lib??vue-loader-options!./src/components/ProductCarousel.vue?vue&type=script&lang=js&
To install them, you can run: npm install --save swiper/css swiper/vue
Edit :
Here is my package.json file :
{
"name": "x",
"version": "0.1.0",
"private": true,
"scripts": {
"serve": "vue-cli-service serve",
"build": "vue-cli-service build",

},
"browserslist": [

}

Everything looks okay, apart from import 'swiper/css'; not needing to be imported.
You could try to delete your node_modules folder and running npm install again

In vue to make js script available you should import it in every component you would like to use in .
Or you can make it available globally by importing it in in main.js
For style you should import it in app.vue after opening style tag to make it global for every component style.
If we can take bootstrap as example.
In main.js
import 'bootstrap'
In app.vue
<style lang="scss"> #import './node_modules/bootstrap/scss/bootstrap';</style>

Axios + Vue + ag-grid-vue ... Dependency not found

So, I'm pretty new to VueJS. Integrating axios has never really been a problem on any of my other apps, but for some reasons this one just won't show up.
It doesn't like npm only, or CDN only, or the current implementation of CDN+npm install.
Hope y'all can help me out! Not really sure what the issue is, and googling hasn't been too helpful.

Change 'import' to 'require', sucrase deployment

I'm trying to put my application into production. But, the teacher who was teaching put it for me, the lib 'sucrase' to use syntax of "import from" instead of "require". Only now Heroku is complaining that he doesn't understand the syntax "import". Is there anything I can do about line of code and configuration? Or do I have to change all "import from" to "require"? ... Lower the logs ...

As you see in the error log : Cannot use import statement outside a module.
import statements are permitted only in ES modules not CommonJS see more about that here :
However you can make Node treat your file as a ES module you need to :
add "type": "module" to package.json .
Add --experimental-modules flag upon running your app(not necessary with Node 13.2.0+ so check your node version with node --version)
as follow :
// package.json
{
"type": "module"
}
take a look here for more information .
OR :
Alternatively you can use the .mjs instead of .jsextension .
SOURCES :

To build my app using sucrase I use:
sucrase ./src -d ./dist --transforms imports
This is my package.json file:
"scripts": {
"dev": "nodemon src/server.js",
"build": "sucrase ./src -d ./dist --transforms imports",
"start": "node dist/server.js"
},

How to use "import" in Node.js?

I tried to deploy my project developed using React and Node.js to Heroku, but after issuing git push heroku master, I got an error:

I googled and it is said that Node.js doesn't support ES6 syntax, and I can solve it by using babel.
But I don't know how to configure it.
Below are my files:
.babelrc.json:
{
"presets": [

And my whole project is on https://github.com/powerseed/e-commerce-React

Thanks in advance!
You can just use require if you want. Here are the details on why there are two ways to bring in files. The difference between "require(x)" and "import x"
per the Nodejs docs I was able to use the following to run node node-module.js and similar may work in your situation--I'm unfamiliar with the specific node version you're working with currently, but the "type":"module" option would likely allow it--I'm using Nodejs v15 at the moment.
package.json
{
"type": "module"
}
node-module.js
import * as os from 'os';
import defaultstuff, { stuff } from './node-import-stuff.js';
console.log(123 === stuff, defaultstuff, Object.keys(os));
node-import-stuff.js
export const stuff = 123;
export default stuff;

Duplicate ReactJS import issue when using npm link to test component before publishing as npm package

I have a simple component like this.
import React, {useState} from 'react';
function MyComponentWithState(props) {
const [value, setValue] = useState(0);
return (
<p>My value is: {value}</p>
)
}
export default MyComponentWithState;
and I want to publish it on NPM as a separate package. so, to do that I prepared package.json and webpack.config.js like below.
package.json:
{
"name": "try-to-publish",
"version": "0.0.1",
"description": "Just a test",
"main": "build/index.js",
"scripts": {
"start": "webpack --watch",
"build": "webpack"
},
"author": {

},

"react-dom": "16.9.0",
"prop-types": "15.7.2",
"react-scripts": "3.1.1",
"webpack": "4.39.3"
},
"devDependencies": {
"#babel/core": "7.6.0",
"#babel/plugin-proposal-class-properties": "7.5.5",
"#babel/preset-env": "7.6.0",
"#babel/preset-react": "7.0.0",
"babel-loader": "8.0.6",

"css-loader": "3.2.0",

"sass-loader": "8.0.0",
"style-loader": "1.0.0",
"webpack-cli": "3.3.8",
"webpack-external-react": "^1.1.2"
}
}
webpack.config.json:
const path = require('path');
module.exports = {
entry: './src/index.js',
output: {
path: path.resolve(__dirname, 'build'),
filename: 'index.js',
libraryTarget: 'commonjs2'
},
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
include: path.resolve(__dirname, 'src'),
use: {
loader: "babel-loader"
}
},
]
},
resolve: {
alias: {
'react': path.resolve(__dirname, 'node_modules/react'),
'react-dom': path.resolve(__dirname, 'node_modules/react-dom'),
}
},
externals: {
'react': "commonjs react",
'react-dom': "commonjs react-dom"
},
};
and here is my .babelrc:
{
"presets": [
"#babel/preset-env",
"#babel/preset-react"
],
"plugins": ["#babel/plugin-proposal-class-properties"]
}
These configs work like charm when I publish my component to NPM and install it in my another ReactJs project with `npm install , but my point is the local test!
I want to test this component/lib before publish. To do this I use npm link feature to link my component with my main ReactJS project.
As you saw above, my component is functional and I used hooks too. So when I inject the locally linked lib to my main ReactJs project face this error,
Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
My issue is related to the 3td reason. My project uses ReactJs and import it once and also my component will import React! I mean twice React import in one project!.
I also have externals config about react and react-dom in my Webpack config.
What should I do to solve that? Where is my mistake?
Update:
I also tried what #sung-m-kim and #eddie-cooro say but it not worked! Mean, I change the package.json and removed react and react-dom from dependencies and add them to devDpendencies.
I finally solved this problem by these steps.
run npm link inside
<your-library-package>/node_modules/react
also
run npm link inside
<your-library-package>/node_modules/react-dom
then run npm link react and npm link react-dom inside your application root directory
and dont forget to keep react and react-dom as externals in the library
// webpack.config.js
const externals = {
"react": "react",
"react-dom": "react-dom",
}
module.exports = {
.
.
.
externals
}
I solved my issue. I used RollupJS instead of Webpack for bundling as bundle tool.
Here is my rollup.config.js:
import {uglify} from 'rollup-plugin-uglify'
import babel from 'rollup-plugin-babel'
export default {
input: "./src/index.js",
external: ['react', 'react-dom'],
output: {
name: 'test-lib',
format: "cjs",
},
plugins: [
babel({
exclude: "node_modules/**"
}),
uglify(),
],
};
and my package.json:
{
"name": "test-lib",
"version": "1.0.0",
"main": "dist/test-lib.min.js",
"scripts": {
"build": "rollup -c -o dist/test-lib.min.js"
},
"author": "Behnam Azimi",
"license": "ISC",
"peerDependencies": {
"react": "^16.9.0",
"react-dom": "^16.9.0"
},
"devDependencies": {
"#babel/core": "^7.6.0",
"#babel/preset-env": "^7.6.0",
"#babel/preset-react": "^7.0.0",
"rollup": "^1.21.4",
"rollup-plugin-babel": "^4.3.3",
"rollup-plugin-commonjs": "^10.1.0",
"rollup-plugin-uglify": "^6.0.3"
}
}
After these changes, npm link worked truly in my ReactJS (Hooks) project.
Notice that it's just a simple Rollup config to show my solution and you can add many kinds of stuff like hot reloading, styles loaders, and many other plugins to the config.
Set the react and react-native packages only inside of the peerDependencies part of package.json, not the dependencies. Also for local development (When your package is not included in any other react projects and you want to to run it locally), you can use the devDependencies field.
I resolve this problem in a typescript react project.
probably, when use the npm link use the react from main app project and the component project.
So, in your package.json remove react from dependencies and/or devDependencies

Trouble importing custom library from a repository into an Ember project as a dependency

I am developing a WebGL library that I would like to import into an EmberJS project as a dependency. Unless I'm mistaken, I believe that I can do this via the repository directly without having to make an npm package but I am having trouble getting it to work.
I have made a watered down library and ember project in a couple repos here and here respectively to demonstrate my problem.
If you clone the library and run npm run build it'll make a test bundle which can be called by the test html file packageTest.html. It should print out 'Hello World Test Member is: 5'.
In the Ember project I have a component in which I would like to import the 'HelloWorld' class from the library and call one of its member methods.
import Ember from 'ember';
//import HelloWorld from 'npm-package-test';
export default Ember.Component.extend({
isWide: false,
actions: {
toggleImageSize() {
// var h = new HelloWorld();
// console.log(h.print());
this.toggleProperty('isWide');
}
}
});
When I uncomment the import statement I get the console error
Error: Could not find module 'npm-package-test'
I'm still pretty new to npm packaging and how dependencies work (and know next to nothing about Ember) but from my limited understanding I feel like this method should work the way I currently have it.
For the library, I have the source files being babeled into ES5 in its lib folder. As you can see in the package.json for the library below I have the main set to the index file in the lib folder so that the Ember project can pull the babeled modules.
Library: package.json

}
When I run npm install in the ember project I can see that the folder structure from the library appears in the node_modules folder. To my limited experience, everything seems correct but for some reason I am still getting this undefined module error.
Is there a step I've missed or some crucial detail I'm missing?
Yes, there’s one step you are still missing. For Ember-CLI to understand that you want to include your npm package in your app’s vendor files, you’ll need to use app.import as outlined here: https://guides.emberjs.com/v3.0.0/addons-and-dependencies/managing-dependencies/
That approach with app.import has existed since Ember-CLI 2.15, but if you are on an older version you’ll need to upgrade first.
