ESBuild Plugin Live Reload

An ESBuild development plugin that watches for file changes and triggers automatic browser refreshes.

Quick start

npm install -D @goauthentik/esbuild-plugin-live-reload
# Or with Yarn:
yarn add -D @goauthentik/esbuild-plugin-live-reload

1. Configure ESBuild

import { liveReloadPlugin } from "@goauthentik/esbuild-plugin-live-reload";

import esbuild from "esbuild";

const NodeEnvironment = process.env.NODE_ENV || "development";

/**
 * @type {esbuild.BuildOptions}
 */
const buildOptions = {
    // ... Your build options.
    define: {
        "process.env.NODE_ENV": JSON.stringify(NodeEnvironment),
    },
    plugins: [
        /** @see {@link LiveReloadPluginOptions} */
        liveReloadPlugin(),
    ],
};

const buildContext = await esbuild.context(buildOptions);

await buildContext.rebuild();
await buildContext.watch();

2. Connect your browser

Add the following import near the beginning of your application's entry point.

if (process.env.NODE_ENV === "development") {
    await import("@goauthentik/esbuild-plugin-live-reload/client");
}

That's it! Your browser will now automatically refresh whenever ESBuild finishes rebuilding your code.
