Dependency free file server for single page app development
最后发布版本: 3.2.0 ( 2020-02-12 00:47:22)
Servør
A dependency free dev server for modern web application development
A very compact but capable static file server with https, live reloading, gzip and other useful features to support modern web app development on localhost and over a local network. The motivation here was to write a package from the ground up with no dependencies; using only native, node and browser APIs to do some specific tasks with minimal code.
Servør can be invoked via the command line or programmatically using the node API.
Quickstart Example
The following command instructs servør to; clone perflink, start a server at the project root, open the url in a browser, open the source code in an editor and reload the browser when files change.
npx servor gh:lukejacksonn/perflink --browse --editor --reload
Most features are disabled by default but you can customize behaviour by passing positional arguments and flags to enable features.
Features
- 🗂 Serves static content like scripts, styles, images from a given directory
- ♻️ Reloads the browser when project files get added, removed or modified
- 🗜 Uses gzip on common filetypes like html, css, js and json
- 🔐 Supports https and http2 with trusted self signed certificates
- 🖥 Redirects all path requests to a single file for frontend routing
- 📦 Accepts both HTML and JavaScript files as the root file for a directory
- 🔎 Discovers freely available ports to start if the default is in use
- 📄 Renders directory listing for urls ending with a trailing slash
- 🗃 Opens browser tab and code editor to streamline quick start
CLI Usage
Run as a terminal command without adding it as a dependency using npx
:
npx servor <root> <fallback> <port>
You can pass a GitHub repo as
<root>
using the syntaxgh:<user>/<repository>
-
<root>
path to serve static files from (defaults to current directory.
) -
<fallback>
the file served for all non-file requests (defaults toindex.html
) -
<port>
what port you want to serve the files from (defaults to8080
)
Optional flags passed as non-positional arguments:
-
--browse
causes the browser to open when the server starts -
--reload
causes the browser to reload when files change -
--secure
starts the server with https using generated credentials -
--silent
prevents the server node process from logging to stdout -
--module
causes the server to wrap the root in script type module tags -
--static
causes the server to route nested index files if they exist -
--editor
opens a code editor (currently only vscode) at the project root
Example usage with npm scripts in a package.json
file after running npm i servor -D
:
{
"devDependencies": {
"servor": "4.0.0"
},
"scripts": {
"start": "servor www index.html 8080 --reload --browse"
}
}
Generating Credentials
NOTE: This process depends on the
openssl
command existing (tested on macOS and linux only)
The files servor.crt
and servor.key
need to exist for the server to start using https. If the files do not exist when the --secure
flag is passed, then certify.sh
is invoked which:
- Creates a local certificate authority used to generate self signed SSL certificates
- Runs the appropriate
openssl
commands to produce:- a root certificate (pem) so the system will trust the self signed certificate
- a public certificate (crt) that the server sends to clients
- a private key for the certificate (key) to encrypt and decrypt traffic
Adding credentials to the trusted store
NOTE: This process depends on the
sudo
andsecurity
commands existing (tested on macOS only)
For the browser to trust self signed certificates the root certificate must be added to the system trusted store. This can be done automatically by running sudo servor --secure
which:
- Adds the root certificate to the system Keychain Access
- Prevents the "⚠️ Your connection is not private" screen
- Makes the 🔒 icon appear in the browsers address bar
The approach was adopted from @kingkool68/generate-ssl-certs-for-local-development
API Usage
Use servor programmatically with node by requiring it as a module in your script:
const servor = require('servor');
const instance = await servor({
root: '.',
fallback: 'index.html',
module: false,
static: false,
reload: false,
inject: ''
credentials: null,
port: 8080,
});
The servor
function accepts a config object with optional props assigned the above default values if none are provided. Calling the servor
function starts up a new server and returns an object describing its configuration.
const { url, root, protocol, port, ips } = await servor(config);
Inject
The inject
property accepts a string that gets appended to the servers root document (which is index.html
by default). This could be used to inject config or extend the development servers behavior and capabilities to suit specific environments.
const config = require('package.json');
servor({ inject: `<script>window.pkg=${config}</script>` });
Credentials
The credentials
property accepts an object containing the entries cert
and key
which must both be valid for the server to start successfully. If valid credentials are provided then the server will start serving over https.
It is possible to generate the appropriate credentials using the --secure
CLI flag.
Notes
Thanks to all the contributors to this projects so far. If you find a bug please create an issue or if you have an idea for a new feature then fork the project and create a pull request. Let me know how you are using servør on twitter.
