Setting up unique part on a package for beginners

Currently implementing Element UI, following the installation process as shown below:

npm i element-ui -S

However, I am not interested in the whole package. Instead, I only require a specific component which is the DatePicker. How can I install this particular component using npm? I have checked the documentation but couldn't find any reference to it. Thanks for your help.

Answer №1

When using npm or Yarn, keep in mind that you can only install a package as a whole along with all its dependencies. Selectively installing specific parts of a package is not supported. For more detailed information, refer to the documentation. As highlighted in the documentation for element-ui, the installation process involves running:

npm i element-ui -S

Alternatively, if you are using Yarn, you can add the package to your package.json and run yarn install.

If you are interested in including only certain components from the package in your Vue app's output bundle, it is indeed possible. Ensure that you import the component by specifying its full path rather than importing the entire library:

import ElementUI from 'element-ui'; // imports the entire library

OR

import { DatePicker } from 'element-ui/lib/Datepicker' // imports only the Datepicker component

Make sure that the path of the component matches its location within the node_modules directory after installation. Additionally, ensure that your Webpack configuration is set up correctly to bundle only the imported JS files, which should be the default behavior.

Answer №2

It may be difficult to install just one component from a UI library due to the dependencies between components in the source code.
However, if you are concerned about the size of importing the entire library into your project,

One solution could be to import the library on demand as shown below:

import Vue from 'vue'
import { DatePicker } from 'element-ui'

Vue.use(DatePicker)

If you use webpack and babel-plugin-component,
the bundle output will only contain necessary code from the library.

You can find more details in the Element QuickStart documentation under the On demand section.

Alternatively, you can explore other DatePicker components for Vue on Awesome Vue if you decide not to use ElementUI.
