What is superstatic?
Superstatic is a static file server that supports modern web development features such as clean URLs, custom headers, and redirects. It is often used for serving static websites and single-page applications (SPAs) with ease.
What are superstatic's main functionalities?
Serving Static Files
This feature allows you to serve static files from a specified directory. In this example, the server serves files from the './public' directory on port 3474.
const superstatic = require('superstatic');
const connect = require('connect');
const app = connect().use(superstatic({
root: './public'
}));
app.listen(3474, () => {
console.log('Server running on port 3474');
});
Clean URLs
This feature enables clean URLs, which means you can serve files without the '.html' extension. For example, 'example.com/about' will serve 'about.html'.
const superstatic = require('superstatic');
const connect = require('connect');
const app = connect().use(superstatic({
root: './public',
cleanUrls: true
}));
app.listen(3474, () => {
console.log('Server running on port 3474');
});
Custom Headers
This feature allows you to set custom headers for your files. In this example, all HTML files will have a 'Cache-Control' header set to 'no-cache'.
const superstatic = require('superstatic');
const connect = require('connect');
const app = connect().use(superstatic({
root: './public',
headers: [{
source: '**/*.html',
headers: [{
key: 'Cache-Control',
value: 'no-cache'
}]
}]
}));
app.listen(3474, () => {
console.log('Server running on port 3474');
});
Redirects
This feature allows you to set up redirects. In this example, requests to '/old-page' will be redirected to '/new-page' with a 301 status code.
const superstatic = require('superstatic');
const connect = require('connect');
const app = connect().use(superstatic({
root: './public',
redirects: [{
source: '/old-page',
destination: '/new-page',
type: 301
}]
}));
app.listen(3474, () => {
console.log('Server running on port 3474');
});
Other packages similar to superstatic
http-server
http-server is a simple, zero-configuration command-line static HTTP server. It is easy to use and can serve static files quickly, but it lacks some of the advanced features like custom headers and redirects that superstatic offers.
live-server
live-server is a simple development HTTP server with live reload capability. It is great for development purposes as it automatically reloads the page when files change. However, it does not offer features like clean URLs or custom headers.
serve
serve is a static file serving and directory listing tool. It is highly configurable and supports features like clean URLs and custom headers, similar to superstatic. However, it is more focused on simplicity and ease of use.
Superstatic
Superstatic is an enhanced static web server that was built to power.
It has fantastic support for HTML5 pushState applications, clean URLs,
caching, and many other goodies.
Documentation
Installation
Superstatic should be installed globally using npm:
For use via CLI
$ npm install -g superstatic
For use via API
npm install superstatic --save
Usage
By default, Superstatic will simply serve the current directory on port
3474
. This works just like any other static server:
$ superstatic
You can optionally specify the directory, port and hostname of the server:
$ superstatic public --port 8080 --host 127.0.0.1
Configuration
Superstatic reads special configuration from a JSON file (either superstatic.json
or divshot.json
by default, configurable with -c
). This JSON file enables
enhanced static server functionality beyond simply serving files.
public: by default, Superstatic will serve the current working directory (or the
ancestor of the current directory that contains the configuration json being used).
This configuration key specifies a directory relative to the configuration file that
should be served. For example, if serving a Jekyll app, this might be set to "_site"
.
A directory passed as an argument into the command line app supercedes this configuration
directive.
clean_urls: if true
, all .html
files will automatically have their extensions
dropped. If .html
is used at the end of a filename, it will perform a 301 redirect
to the same path with .html
dropped.
All paths have clean urls
{
"clean_urls": true
}
Only specific paths get clean urls
{
"clean_urls": ["/app/**", "/!components/**"]
}
rewrites: you can specify custom route recognition for your application by supplying
an object to the routes key. Use a single star *
to replace one URL segment or a
double star to replace an arbitrary piece of URLs. This works great for single page
apps. An example:
{
"rewrites": [
{"source":"app/**","destination":"/application.html"},
{"source":"projects/*/edit","destination":"/projects.html"}
]
}
redirects: you can specify certain url paths to be redirected to another url by supplying configuration to the redirects
key. Path matching is similar to using custom routes. Redirects use the 301
HTTP status code by default, but this can be overridden by configuration.
{
"redirects": [
{"source":"/some/old/path", "destination":"/some/new/path"},
{"source":"/firebase/*", "destination":"https://www.firebase.com", "type": 302}
]
}
Route segments are also supported in the redirects configuration. Segmented redirects also support custom status codes (see above):
{
"redirects": [
{"source":"/old/:segment/path", "destination":"/new/path/:segment"}
]
}
In this example, /old/custom-segment/path
redirects to /new/path/custom-segment
headers: Superstatic allows you to set the response headers for certain paths as well:
{
"headers": [
{
"source" : "**/*.@(eot|otf|ttf|ttc|woff|font.css)",
"headers" : [{
"key" : "Access-Control-Allow-Origin",
"value" : "*"
}]
}, {
"source" : "**/*.@(jpg|jpeg|gif|png)",
"headers" : [{
"key" : "Cache-Control",
"value" : "max-age=7200"
}]
}, {
"source" : "404.html",
"headers" : [{
"key" : "Cache-Control",
"value" : "max-age=300"
}]
}]
}
}
trailing_slash: Have full control over whether or not your app has or doesn't have trailing slashes. By default, Superstatic will make assumptions for on the best times to add or remove the trailing slash. Other options include true
, which always adds a trailing slash, and false
, which always removes the trailing slash.
{
"trailing_slash": true
}
API
Superstatic is available as a middleware and a standalone Connect server. This means you can plug this into your current server or run your own static server using Superstatic's server.
Middleware
var superstatic = require('superstatic')
var connect = require('connect');
var app = connect()
.use(superstatic());
app.listen(3000, function () {
});
superstatic([options])
Insantiates middleware. See an example for detail on real world use.
options
- Optional configuration:
config
- A file path to your application's configuration file (see Configuration) or an object containing your application's configuration.protect
- Adds HTTP basic auth. Example: username:password
env
- A file path your application's environment variables file or an object containing values that are available at the urls /__/env.json
and /__/env.js
. See the documentation detail on environment variables.cwd
- The current working directory to set as the root. Your application's root configuration option will be used relative to this.services
- An object containing various Superstatic services.
Server
var superstatic = require('superstatic').server;
var app = superstatic();
var server = app.listen(function () {
});
Since Superstatic's server is a barebones Connect server using the Superstatic middleware, see the Connect documentation on how to correctly instantiate, start, and stop the server.
superstatic([options])
Instantiates a Connect server, setting up Superstatic middleware, port, host, debugging, compression, etc.
options
- Optional configuration. Uses the same options as the middleware, plus a few more options:
port
- The port of the server. Defaults to 3474
.host
or hostname
- The hostname of the server. Defaults to localhost
.errorPage
- A file path to a custom error page. Defaults to Superstatic's error page.debug
- A boolean value that tells Superstatic to show or hide network logging in the console. Defaults to false
.gzip
- A boolean value that tells Superstatic to gzip response body. Defaults to false
.
