Next.js + Images

npm npm npm

Import images in Next.js (jpg, jpeg, svg, png, ico, webp and gif images)

Features

  • Load images from local computer
  • Load images from remote (CDN for example) by setting assetPrefix
  • Inline small images to Base64 for reducing http requests
  • Adds a content hash to the file name so images can get cached

If you also want image minimalization and optimization have a look at next-optimized-images

Installation

npm install --save next-images

or

yarn add next-images

Usage

Create a next.config.js in your project

// next.config.js
const withImages = require('next-images')
module.exports = withImages()

Optionally you can add your custom Next.js configuration as parameter

// next.config.js
const withImages = require('next-images')
module.exports = withImages({
  webpack(config, options) {
    return config
  }
})

And in your components or pages simply import your images:

export default () => <div>
  <img src={require('./my-image.jpg')} />
</div>

or

import img from './my-image.jpg'
 
export default () => <div>
  <img src={img} />
</div>

Options

assetPrefix

You can serve remote images by setting assetPrefix option.

Example usage:

// next.config.js
const withImages = require('next-images')
module.exports = withImages({
  assetPrefix: 'https://example.com',
  webpack(config, options) {
    return config
  }
})

InlineImageLimit

Inlines images with sizes below inlineImageLimit to Base64. Default value is 8192.

Example usage:

// next.config.js
const withImages = require('next-images')
module.exports = withImages({
  inlineImageLimit: 16384,
  webpack(config, options) {
    return config
  }
})

Exclude

Folders that you want to exclude from the loader. Useful for svg-react-loader for example.

Example usage:

// next.config.js
const path = require('path');
const withImages = require('next-images')
module.exports = withImages({
  exclude: path.resolve(__dirname, 'src/assets/svg'),
  webpack(config, options) {
    return config
  }
})

ES Modules

By default, file-loader generates JS modules that use the ES modules syntax. There are some cases in which using ES modules is beneficial, like in the case of module concatenation and tree shaking.

ES Modules are disabled by default. You can enable them by using esModule config option:

const withImages = require('next-images')
module.exports = withImages({
  esModule: true,
  webpack(config, options) {
    return config
  }
})

By enabling ES modules you should change your require statements and get default property out of them:

<img src={require("./img.png").default}>

import statement should be as before.

import img from "./img.png";

Typescript

Typescript doesn't know how interpret imported images. next-images package contains definitions for image modules, you need to add reference to next-images types (third line) into your next-env.d.ts file.

/// <reference types="next" />
/// <reference types="next/types/global" />
 
+ /// <reference types="next-images" />
