Installation is done using the +[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): + +```sh +$ npm install serve-static +``` + +## API + +```js +var serveStatic = require('serve-static') +``` + +### 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, instead of +sending a 404 response, this module will instead call `next()` to move on +to the next middleware, allowing for stacking and fall-backs. + +#### Options + +##### acceptRanges + +Enable or disable accepting ranged requests, defaults to true. +Disabling this will not send `Accept-Ranges` and ignore the contents +of the `Range` request header. + +##### cacheControl + +Enable or disable setting `Cache-Control` response header, defaults to +true. Disabling this will ignore the `immutable` and `maxAge` options. + +##### dotfiles + + Set how "dotfiles" are treated when encountered. A dotfile is a file +or directory that begins with a dot ("."). Note this check is done on +the path itself without checking if the path actually exists on the +disk. If `root` is specified, only the dotfiles above the root are +checked (i.e. the root itself can be within a dotfile when set +to "deny"). + + - `'allow'` No special treatment for dotfiles. + - `'deny'` Deny a request for a dotfile and 403/`next()`. + - `'ignore'` Pretend like the dotfile does not exist and 404/`next()`. + +The default value is similar to `'ignore'`, with the exception that this +default will not ignore the files within a directory that begins with a dot. + +##### etag + +Enable or disable etag generation, defaults to true. + +##### extensions + +Set file extension fallbacks. When set, if a file is not found, the given +extensions will be added to the file name and search for. The first that +exists will be served. Example: `['html', 'htm']`. + +The default value is `false`. + +##### fallthrough + +Set the middleware to have client errors fall-through as just unhandled +requests, otherwise forward a client error. The difference is that client +errors like a bad request or a request to a non-existent file will cause +this middleware to simply `next()` to your next middleware when this value +is `true`. When this value is `false`, these errors (even 404s), will invoke +`next(err)`. + +Typically `true` is desired such that multiple physical directories can be +mapped to the same web address or for routes to fill in non-existent files. + +The value `false` can be used if this middleware is mounted at a path that +is designed to be strictly a single file system directory, which allows for +short-circuiting 404s for less overhead. This middleware will also reply to +all methods. + +The default value is `true`. + +##### immutable + +Enable or disable the `immutable` directive in the `Cache-Control` response +header, defaults to `false`. If set to `true`, the `maxAge` option should +also be specified to enable caching. The `immutable` directive will prevent +supported clients from making conditional requests during the life of the +`maxAge` option to check if the file has changed. + +##### index + +By default this module will send "index.html" files in response to a request +on a directory. To disable this set `false` or to supply a new index pass a +string or an array in preferred order. + +##### lastModified + +Enable or disable `Last-Modified` header, defaults to true. Uses the file +system's last modified value. + +##### maxAge + +Provide a max-age in milliseconds for http caching, defaults to 0. This +can also be a string accepted by the [ms](https://www.npmjs.org/package/ms#readme) +module. + +##### redirect + +Redirect to trailing "/" when the pathname is a dir. Defaults to `true`. + +##### setHeaders + +Function to set custom headers on response. Alterations to the headers need to +occur synchronously. The function is called as `fn(res, path, stat)`, where +the arguments are: + + - `res` the response object + - `path` the file path that is being sent + - `stat` the stat object of the file that is being sent + +## Examples + +### Serve files with vanilla node.js http server + +```js +var finalhandler = require('finalhandler') +var http = require('http') +var serveStatic = require('serve-static') + +// Serve up public/ftp folder +var serve = serveStatic('public/ftp', { index: ['index.html', 'index.htm'] }) + +// Create server +var server = http.createServer(function onRequest (req, res) { + serve(req, res, finalhandler(req, res)) +}) + +// Listen +server.listen(3000) +``` + +### Serve all files as downloads + +```js +var contentDisposition = require('content-disposition') +var finalhandler = require('finalhandler') +var http = require('http') +var serveStatic = require('serve-static') + +// Serve up public/ftp folder +var serve = serveStatic('public/ftp', { + index: false, + setHeaders: setHeaders +}) + +// Set header to force download +function setHeaders (res, path) { + res.setHeader('Content-Disposition', contentDisposition(path)) +} + +// Create server +var server = http.createServer(function onRequest (req, res) { + serve(req, res, finalhandler(req, res)) +}) + +// Listen +server.listen(3000) +``` + +### Serving using express + +#### Simple + +This is a simple example of using Express. + +```js +var express = require('express') +var serveStatic = require('serve-static') + +var app = express() + +app.use(serveStatic('public/ftp', { index: ['default.html', 'default.htm'] })) +app.listen(3000) +``` + +#### Multiple roots + +This example shows a simple way to search through multiple directories. +Files are searched for in `public-optimized/` first, then `public/` second +as a fallback. + +```js +var express = require('express') +var path = require('path') +var serveStatic = require('serve-static') + +var app = express() + +app.use(serveStatic(path.join(__dirname, 'public-optimized'))) +app.use(serveStatic(path.join(__dirname, 'public'))) +app.listen(3000) +``` + +#### Different settings for paths + +This example shows how to set a different max age depending on the served +file type. In this example, HTML files are not cached, while everything else +is for 1 day. + +```js +var express = require('express') +var path = require('path') +var serveStatic = require('serve-static') + +var app = express() + +app.use(serveStatic(path.join(__dirname, 'public'), { + maxAge: '1d', + setHeaders: setCustomCacheControl +})) + +app.listen(3000) + +function setCustomCacheControl (res, path) { + if (serveStatic.mime.lookup(path) === 'text/html') { + // Custom Cache-Control for HTML files + res.setHeader('Cache-Control', 'public, max-age=0') + } +} +``` + +## License + +[MIT](LICENSE) + +[appveyor-image]: https://badgen.net/appveyor/ci/dougwilson/serve-static/master?label=windows +[appveyor-url]: https://ci.appveyor.com/project/dougwilson/serve-static +[coveralls-image]: https://badgen.net/coveralls/c/github/expressjs/serve-static/master +[coveralls-url]: https://coveralls.io/r/expressjs/serve-static?branch=master +[github-actions-ci-image]: https://badgen.net/github/checks/expressjs/serve-static/master?label=linux +[github-actions-ci-url]: https://github.com/expressjs/serve-static/actions/workflows/ci.yml +[node-image]: https://badgen.net/npm/node/serve-static +[node-url]: https://nodejs.org/en/download/ +[npm-downloads-image]: https://badgen.net/npm/dm/serve-static +[npm-url]: https://npmjs.org/package/serve-static +[npm-version-image]: https://badgen.net/npm/v/serve-static |
