Note for Remix Users

Remix users should add "react-image-grid-gallery" to their remix.config.js file:

1/** @type {import('@remix-run/dev').AppConfig} */
2module.exports = {
3  ignoredRouteFiles: ["**/.*"],
4+ serverDependenciesToBundle: ["react-image-grid-gallery"],
5  serverModuleFormat: "cjs",
6};

The serverDependenciesToBundle field tells Remix to transpile and include the "react-image-grid-gallery" package in the server bundle.

Note for NextJS users

NextJS users should declare the "use client" directive at the top of their file. It should sit above all other import statements like so:

1+ "use client";
2import { ImageGallery } from "react-image-grid-gallery";
3import { YouTubePlaylist } from "@codesweetly/react-youtube-playlist";

The "use client" directive tells NextJS to consider all modules imported into the page as part of the Client Component module graph.

The ImageGallery package works only as a Client Component because it uses React's State and Lifecycle effects, such as useState() and useEffect().

Note for Docusaurus users

Did you get a ReferenceError: crypto is not defined error during the build step? If so, this note is for you.

Wrap the ImageGallery component in <BrowserOnly> if you get a ReferenceError: crypto is not defined error during your build step.

1import BrowserOnly from "@docusaurus/BrowserOnly";
2
3function YourComponent() {
4  return (
5    <BrowserOnly fallback={<div>Loading...</div>}>
6      {() => {
7        const ImageGallery = require("react-image-grid-gallery").ImageGallery;
8        return (
9          <ImageGallery
10            imagesInfoArray={imagesArray}
11            columnCount={"auto"}
12            columnWidth={230}
13            gapSize={24}
14          />
15        );
16      }}
17    </BrowserOnly>
18  );
19}

This process is essential if your imagesArray uses the Web Crypto API. The <BrowserOnly> component tells Docusaurus to render the ImageGallery library only in the browser. It ensures that the Crypto API runs only in CSR (Client-Side Rendering) rather than during build or SSR (Server-Side Rendering).
