Getting Started

Install

bun add -d @gtramontina.com/bun-html-live-reload

Usage

Using the following as a regular Bun server as a starting point:

// index.ts

Bun.serve({
    fetch: () => {
        return new Response("<div>hello world!</div>", {
            headers: { "Content-Type": "text/html" },
        });
    },
    port: 8888,
});

Import htmlLiveReload and wrap your server with it:

// index.ts

import { htmlLiveReload } from "@gtramontina.com/bun-html-live-reload";

Bun.serve(
    htmlLiveReload({
        fetch: () => {
            return new Response("<div>hello world!</div>", {
                headers: { "Content-Type": "text/html" },
            });
        },
        port: 8888,
    }),
);

Running the server with bun --hot index.ts will now force a reload of the current page whenever Bun --hot detects a change. It will also force a reload of the stylesheets when a change to a text/css file is detected. For an example, take a look at the example directory and run bun run:example.

Options

watchPath

Bun HTML Live Reload will always force a reload when running it --hot. In order to have a more fine-grained control over the files not detected by Bun's --hot mode, the watchPath option can be passed to htmlLiveReload as such:

// index.ts

import { htmlLiveReload } from "@gtramontina.com/bun-html-live-reload";

Bun.serve(
    htmlLiveReload(
        { /* server options */ },
        {
            watchPath: path.resolve(import.meta.dir, "src"),
        }
    ),
);

buildConfig

If your setup makes use of Bun.build(), you can forward the settings to htmlLiveReload via the buildConfig option:

// index.ts

import { htmlLiveReload } from "@gtramontina.com/bun-html-live-reload";

Bun.serve(
    htmlLiveReload(
        { /* server options */ },
        {
            buildConfig: {
                entrypoints: ['./index.tsx'],
                outdir: './build',
            },
        }
    ),
);
