# react-dynamic-import
⚠️ You might not need this library. Checkout [`React.lazy`](https://reactjs.org/docs/code-splitting.html#reactlazy) and see if it fits your use case.
Dynamically load and render any react module(Component or an HOC) using dynamic import 🎉
Tiny(**around 1.16kb gzip**) dynamic module loader and renderer.
👉 [DEMO](https://codesandbox.io/s/react-dynamic-import-hooks-demo-108-kuf3u)
> ⚠️ Hooks only(requires react 16.8.0 or above), use [v1.0.4](https://www.npmjs.com/package/react-dynamic-import/v/1.0.4) if you want older react versions support
>
> Dynamic loading of component is already supported in React using React.lazy and Suspense, But, dynamic loading of HOC is tricky and is unsupported in React.
>
> Should work with any bundler(eg: webpack, parcel etc) which supports dynamic import ✨

## Install
### NPM
```sh
npm install react-dynamic-import
```
### Yarn
```sh
yarn add react-dynamic-import
```
### UMD build
```html
```
## Basic usage
1. Component
- **Folder structure**
```text
|_ realComponent.js
|_ container.js <-- working file
```
- **Usage**
```js
// Import library
import ReactDynamicImport from "react-dynamic-import";
// or const ReactDynamicImport = require('react-dynamic-import');
// Define dynamic import loader function
const loader = () => import(`./realComponent.js`);
/**
* Use dynamic module and lazy fetch component
*
* Make sure to use it outside render method,
* else new component is rendered in each render
*
* You can choose to show a placeholder and render
* error component in case of error, check API section for more
*/
const RealComponent = ReactDynamicImport({ loader });
class Container extends React.component {
render() {
/**
* This component is dynamically fetched and rendered
* on first usage/render
*/
return ;
}
}
```
1. HOC
- **Folder structure**
```text
|_ realComponent.js <-- Real component to wrap in HOC
|_ withHOC.js <-- HOC
|_ container.js <-- working file
```
- **Usage**
```js
// Import library
import ReactDynamicImport from "react-dynamic-import";
// or const ReactDynamicImport = require('react-dynamic-import');
import RealComponent from "./realComponent.js";
// Define dynamic import loader function
const loader = () => import(`./withHOC.js`);
/**
* Use dynamic module and lazy fetch HOC
*
* Make sure to use it outside render method,
* else new component is rendered in each render
*
* You can choose to show a placeholder and render error
* component in case of error, check API section for more
*/
const DynamicHOC = ReactDynamicImport({ loader, isHOC: true });
const WrappedComponent = DynamicHOC(RealComponent);
class Container extends React.component {
render() {
/**
* The actual HOC is lazy loaded and executed,
* which in turn renders the actual component lazily
*/
return ;
}
}
```
## Advanced usage
1. Component
- **Folder structure**
```text
|_ dynamic
| |_ realComponent-en.js
| |_ realComponent-eu.js
| |_ realComponent-kn.js
|_ container.js <-- working file
```
- **Usage**
```js
// Import library
import ReactDynamicImport from "react-dynamic-import";
// or const ReactDynamicImport = require('react-dynamic-import');
/**
* Define dynamic import loader function
*
* This loads specific module from many available
* modules in the directory, using given module name
*/
const loader = f => import(`./dynamic/${f}.js`);
// Use dynamic module and lazy fetch component
class Container extends React.component {
constructor(props) {
super(props);
/**
* Make sure to use it outside render method, else
* new component is rendered in each render
*
* You can choose to show a placeholder and render error
* component in case of error, check API section for more
*
* This loads different module when different language
* configuration is passed
*/
this.RealComponent = ReactDynamicImport({
name: `realComponent-${props.lang || "en"}`,
loader
});
}
render() {
const { RealComponent } = this;
/**
* This component is dynamically fetched and rendered
* on first usage/render
*/
return ;
}
}
```
1. HOC
- **Folder structure**
```text
|_ dynamic <-- Dynamic HOC's
| |_ withHOC-en.js
| |_ withHOC-eu.js
| |_ withHOC-kn.js
|_ realComponent.js <-- Real component to wrap in HOC
|_ container.js <-- working file
```
- **Usage**
```js
// Import library
import ReactDynamicImport from "react-dynamic-import";
// or const ReactDynamicImport = require('react-dynamic-import');
import RealComponent from "./realComponent.js";
/**
* Define dynamic import loader function
*
* This loads specific module from many available
* modules in the directory, using given module name
*/

* component in case of error, check API section for more
*
* This loads different module when different language
* configuration is passed
*/
const DynamicHOC = ReactDynamicImport({
name: `withHOC-${props.lang || "en"}`,
loader,
isHOC: true
});
this.WrappedComponent = DynamicHOC(RealComponent);
}
render() {
const { WrappedComponent } = this;
/**
* The actual HOC is lazy loaded and executed,
