Problem Dynamically Importing Components at Runtime in NextJS: Solutions and Workarounds

When building dynamic and scalable applications with NextJS, one of the common challenges developers face is dynamically importing components at runtime. In this article, we’ll delve into the reasons behind this issue and explore solutions and workarounds to help you overcome it.

The Problem: Dynamic Imports in NextJS

In NextJS, components are typically imported statically using ES6 imports, which allows for optimal code splitting and server-side rendering. However, when you need to import components dynamically at runtime, things get complicated.

The main issue is that NextJS uses a static site generation (SSG) approach, which means that the application is pre-built during the build process. This makes it challenging to import components dynamically at runtime, as the necessary code might not be available.

Causes of the Problem

• NextJS’s SSG approach, which pre-builds the application
• Limited support for dynamic imports in Webpack
• Component code not being available at runtime

Solutions and Workarounds

Fortunately, there are ways to dynamically import components at runtime in NextJS. Here are some solutions and workarounds to help you overcome this challenge:

1. Using the next/dynamic Module

The next/dynamic module provides a way to dynamically import components at runtime. This module uses a dedicated chunk for each dynamic import, allowing for optimal code splitting.

Example:

import dynamic from 'next/dynamic';

const MyDynamicComponent = dynamic(() => import('../components/MyComponent'));

2. Utilizing the loadable-components Library

The loadable-components library provides a way to dynamically import components using a higher-order component (HOC). This library works seamlessly with NextJS and allows for easy code splitting.

Example:

import loadable from '@loadable/component';

const MyDynamicComponent = loadable(() => import('../components/MyComponent'));

3. Implementing a Custom Solution using Webpack

If the above solutions don’t meet your requirements, you can implement a custom solution using Webpack’s dynamic import capabilities. This approach requires more effort, but provides a high degree of customization.

Example:

import webpack from 'webpack';

const dynamicImport = webpackChunkName => {
  return import(`../components/${webpackChunkName}`);
};

const MyDynamicComponent = dynamicImport('MyComponent');

Conclusion

Dynamically importing components at runtime in NextJS can be challenging, but there are solutions and workarounds available. By using the next/dynamic module, loadable-components library, or implementing a custom solution using Webpack, you can overcome this issue and build dynamic and scalable applications with NextJS.

Remember to choose the solution that best fits your project requirements, and don’t hesitate to explore further if you encounter any issues.
