Serve static files using Bun.serve or Bao.js.

Currently in beta. Aiming for similar features as expressjs/serve-static.

Install

This is a Bun module available through the npm registry. Installation is done using the bun install command:

bun install serve-static-bun

Usage

import serveStatic from "serve-static-bun";

serveStatic(root, options)

Create a new middleware function to serve files from within a given root directory. The file to serve will be determined by combining req.url with the provided root directory.

When a file is not found, it will send a 404 response. If a directory is accessed, but no index file is found, a 403 response will be sent.

When used in middleware mode, the 404 and 403 responses will not be sent and will instead return the context to Bao.js, so that other routes can continue.

By default, slashes are automatically collapsed in the path, and a trailing slash is added when the path is a directory. For example, if you have blog/example/index.html and access https://example.com//blog///example, it will redirect to https://example.com/blog/example/.

Options

index

By default this module will send "index.html" files in response to a request on a directory. To disable this, set it to null. To supply a new index, pass a string.

dirTrailingSlash

Redirect to trailing "/" when the pathname is a dir. Defaults to true.

collapseSlashes

Collapse all slashes in the pathname (//blog///test => /blog/test). Defaults to true.

stripFromPathname

Removes the first occurence of the specified string from the pathname. Is not defined by default (no stripping).

headers

Headers to add to the response. The "Content-Type" header cannot be overwritten. If you want to change the charset, use the charset option. If collapseSlashes or dirTrailingSlash is set, a "Location" header will be set if the pathname needs to be changed.

dotfiles

This option allows you to configure how the module handles dotfiles, i.e. files or directories that begin with a dot ("."). Dotfiles return a 403 by default (when this is set to "deny"), but this can be changed with this option.

defaultMimeType

The default mime type to send in the "Content-Type" HTTP header, when the file's cannot be determined. Defaults to text/plain.

charset

The "Content-Type" HTTP header charset parameter. Defaults to utf-8.

Middleware mode options

middlewareMode

When set to "bao", it will return a Bao.js compatible handler function instead.

handleErrors

If set to false, in the case of a 403 or 404 response, the unmodified context will be returned to Bao.js. This allows you to handle the error yourself.
If set to true, the error response will be sent to the client, without continuing the middleware chain.
Defaults to false.

Examples

Serve files with vanilla Bun.serve

import serveStatic from "serve-static-bun";

Bun.serve({ fetch: serveStatic("public") });

Serve files with Bao.js

import Bao from "baojs";
import serveStatic from "serve-static-bun";

const app = new Bao();

// *any can be anything
// We need to strip /assets from the pathname, because when the root gets combined with the pathname,
// it results in /assets/assets/file.js.
app.get(
	"/assets/*any",
	serveStatic("assets", { middlewareMode: "bao", stripFromPathname: "/assets" }),
);

app.get("/", (ctx) => ctx.sendText("Hello Bao!"));

app.listen();

Serve only static files with Bao.js

All paths will be handled by serve-static-bun.

import Bao from "baojs";
import serveStatic from "serve-static-bun";

const app = new Bao();

// *any can be anything
app.get("/*any", serveStatic("web", { middlewareMode: "bao" }));

app.listen();
