I have a Vuejs project created with vue init webpack command.
Then, vue-datetime-picker module is installed with
npm install --save vue-datetime-picker
Then inside a project component source file I'm trying to import the component
import VueDatetimePicker from 'vue-datetime-picker'
// OR
// var VueDatetimePicker = require('vue-datetime-picker')
console.log('VueDatetimePicker: ', VueDatetimePicker)
browser console output
VueDatetimePicker: {}
the node module src folder content
node_modules/vue-datetime-picker/src$ ls
i18n/
vue-datetime-picker.js
It seems you are using Vue.js 2, but this component is using Vue.js 1, it has a lot of change, you can read here: https://v2.vuejs.org/v2/guide/migration.html .

In one of my projects, I build a nice vue3 component that could be useful to several other projects. So I decided to publish it as an NPM package and share it with everyone.
I wrote the isolate component, build it and publish BUT I use Tailwind css to make the style.
When I publish and install the component everything is working BUT without the beauty of the css part.
I tried several configurations and alternative tools to generate the package that automatically add the tailwind as an inner dependency to my package.
Does someone have experience with this? how can build/bundle my component by adding the tailwind CSS instructions into it?
You're almost there
Since you've got your component working, the majority of the part has been done.
For configuring the styling of the component you need to identify the Tailwind CSS classes being used by your Vue component package and retain them in the final CSS that is generated by the Tailwind engine in your project.
Follow below steps in the project where you want to use your tailwind vue component package.
For Tailwind CSS V3
// tailwind.config.js
module.exports = [
//...
content: [
"./index.html",
"./src/**/*.{vue,js,ts,jsx,tsx}",
"./node_modules/package-name/**/*.{vue,js,ts,jsx,tsx}" // Add this line
// Replace "package-name" with the name of the dependency package
],
//...
]
For Tailwind CSS V2
// tailwind.config.js
module.exports = [
//...
purge: {
//...
content: [
"./index.html",
"./src/**/*.{vue,js,ts,jsx,tsx}",
"./node_modules/package-name/**/*.{vue,js,ts,jsx,tsx}" // Add this line
// Replace "package-name" with the name of the dependency package
],
//...
//...
}
]
The content property in the tailwind.config.js file defines file path pattern that the tailwind engine should look into, for generating the final CSS file.
For Pro users
You may also try to automate the above setup by writing an install script for your npm package to add this configuration to the tailwind.config.js file

It's a bit difficult for someone to answer your question as you've not really shared the source code, but thankfully (and a bit incorrectly), you've published the src directory to npm.
The core issue here is that when you're building a component library, you are running npm run build:npm which translates to vue-cli-service build --target lib --name getjvNumPad src/index.js.
The index.js reads as follows:
import component from './components/numeric-pad.vue'
// Declare install function executed by Vue.use()
export function install (Vue) {
if (install.installed) return
install.installed = true
Vue.component('getjv-num-pad', component)
}
// Create module definition for Vue.use()
const plugin = {
install
}
// Auto-install when vue is found (eg. in browser via <script> tag)
let GlobalVue = null
if (typeof window !== 'undefined') {
GlobalVue = window.Vue
} else if (typeof global !== 'undefined') {
GlobalVue = global.Vue
}
if (GlobalVue) {
GlobalVue.use(plugin)
}
// To allow use as module (npm/webpack/etc.) export component
export default component
There is no mention of importing any CSS, hence no CSS included in the built version.
The simplest solution would be to include the index.css import in your index.js or the src/components/numeric-pad.vue file under the <style> section.
Lastly, I'm a bit rusty on how components are built, but you might find that Vue outputs the CSS as a separate file. In that case, you would also need to update your package.json to include an exports field.
How do we import js file from cdn?
I am building a custom component (a wrapper component) to view the pdf files. and for this I need to use pdf.js file from cdn and I am unable to import the file?
following does not work
import "https://cdnjs.cloudflare.com/ajax/libs/pdf.js/2.2.228/pdf.min.js";
To import the JS file from CDN and use in vue.js component, you can use mounted lifecycle and there you need to append your script into DOM.
Then it will be available into your window global variable.
Working code example:
mounted () {
let pdfJS = document.createElement('script')
pdfJS.setAttribute('src', 'https://cdnjs.cloudflare.com/ajax/libs/pdf.js/2.2.228/pdf.min.js')
document.head.appendChild(pdfJS)
// for checking whether it's loaded in windows are not, I am calling the below function.
this.checkPDFJSLib()
},
methods: {
checkPDFJSLib() {
console.log(window.pdfjsLib)
}
}
You can normally include it in your index.html
<script src="https://cdnjs.cloudflare.com/ajax/libs/pdf.js/2.2.228/pdf.min.js"></script>
Alternatively, you can use an npm library e.g vue-pdf
install it into your modules
npm install --save vue-pdf
and use it
import pdf from 'vue-pdf'
I am building a standalone Vue component and using it in another Vue project.
Build component:
vue build --target wc --inline-vue --name user-menu user-menu.vue
It's a simple component so far without functionality, just markup.
Then, in the main project in package.json:
"devDependencies": {
"user-menu": "git+https://........user-menu.git",
Then, in the main.js:
import Vue from "vue";
import UserMenu from "user-menu"
....
Vue.use(UserMenu);
const app = new Vue(config).$mount("#root");
window.app = app;
Vue.use(UserMenu);
And it says:
user-menu.js?e2ea:1446 Uncaught ReferenceError: Vue is not defined
on a row
module.exports = Vue;
But the Vue CLI 3 documentation says that:
In web component mode, Vue is externalized. This means the bundle will
not bundle Vue even if your code imports Vue. The bundle will assume
Vue is available on the host page as a global variable.
Any idea how to fix that?
Finally I came to the following solution: the component should not be built at all. Source files are enought to be imported like this:
import UserMenu from "user-menu/user-menu";
Pay attention that the path should point at the imported vue file, not just to the folder. But the extension "vue" must be skipped.
The final application will build it all together.
I am new in React Native. Right now, I am studying Props and State. I wanted to try the FlatList Component in this doc https://facebook.github.io/react-native/docs/flatlist. However, I am getting this error.
You're using typed JavaScript known as Type script.
If you want to use TypeScript (I highly encourage it, then you can do so by following below tutorial):

To just get rid of the error!

Adding TypeScript
The next step is to add TypeScript to your project. The following commands will:
add TypeScript to your project
add React Native TypeScript Transformer to your project
initialize an empty TypeScript config file, which we'll configure next
add an empty React Native TypeScript Transformer config file, which we'll - configure next
adds typings for React and React Native
Okay, let's go ahead and run these.
yarn add --dev typescript
yarn add --dev react-native-typescript-transformer
yarn tsc --init --pretty --jsx react
touch rn-cli.config.js
yarn add --dev #types/react #types/react-native
The tsconfig.json file contains all the settings for the TypeScript compiler. The defaults created by the command above are mostly fine, but open the file and uncomment the following line:
{
/* Search the config file for the following line and uncomment it. */
// "allowSyntheticDefaultImports": true, /* Allow default imports from modules with no default export. This does not affect code emit, just typechecking. */
}
The rn-cli.config.js contains the settings for the React Native TypeScript Transformer. Open it and add the following:
module.exports = {
getTransformModulePath() {
return require.resolve('react-native-typescript-transformer');
},
getSourceExts() {
return ['ts', 'tsx'];
},
};
Migrating to TypeScript
Rename the generated App.js and __tests_/App.js files to App.tsx. index.js needs to use the .js extension. All new files should use the .tsx extension (or .ts if the file doesn't contain any JSX).
If you tried to run the app now, you'd get an error like object prototype may only be an object or null. This is caused by a failure to import the default export from React as well as a named export on the same line. Open App.tsx and modify the import at the top of the file:
-import React, { Component } from 'react';
+import React from 'react'
+import { Component } from 'react';
Some of this has to do with differences in how Babel and TypeScript interoperate with CommonJS modules. In the future, the two will stabilize on the same behaviour.
At this point, you should be able to run the React Native app.
I've created a new vue app using vue init webpack sample-app .
I'm trying to import this module (https://docs.botui.org/install.html) into my app.vue and make it show on.
What's the correct way to import this module into a Vue.JS app?
Open the terminal in your project root folder, then install the package:
npm install botui --save
Then open src/main.js in your text editor and add this:
import Vue from 'vue'
import BotUI from 'botui'
const botui = BotUI('my-botui-app', {
vue: Vue // pass the dependency.
})
This will create a botui instance. But that instance won't have any messages in it. You can check that it's working by adding a message:
botui.message.bot('Hello, how can I help?')
