 # local-web-server
-Fires up a simple, CORS-enabled, static web server on a given port. Use for local web development or file sharing (directory browsing enabled).
+A simple web-server for productive front-end development.
 
-![local-web-server](http://75lb.github.io/local-web-server/ws.gif)
+**Requires node v4.0.0 or higher**.
 
-## Install
-Ensure [node.js](http://nodejs.org) is installed first. Linux/Mac users may need to run the following commands with `sudo`.
+## Synopsis
+For the examples below, we assume we're in a project directory looking like this:
 
-### Globally
 ```sh
-$ npm install -g local-web-server
+.
+├── css
+│   └── style.css
+├── index.html
+└── package.json
 ```
 
-### Bundled with your project
-```sh
-$ npm install local-web-server --save-dev
-```
+All paths/routes are specified using [express syntax](http://expressjs.com/guide/routing.html#route-paths).
 
-Then add an `start` script to your `package.json` (the standard npm approach):
-```json
-{
-  "name": "my-web-app",
-  "version": "1.0.0",
-  "scripts": {
-    "start": "ws"
-  }
-}
-```
-This simplifies a rather specific-looking instruction set like:
+### Static site
 
+Fire up your static site on the default port:
 ```sh
-$ npm install
-$ npm install -g local-web-server
 $ ws
+serving at http://localhost:8000
 ```
 
-to the following, server implementation and launch details abstracted away:
+### Single Page Application
+
+You're building a web app with client-side routing, so mark `index.html` as the SPA.
 ```sh
-$ npm install
-$ npm start
+$ ws --spa index.html
 ```
 
-## Usage
-```
-Usage
-$ ws <server options>
-$ ws --config
-$ ws --help
+By default, typical SPA urls (e.g. `/user/1`, `/login`) would return `404 Not Found` as a file does not exist with that path. By marking `index.html` as the SPA you create this rule:
 
-Server
--p, --port <number>           Web server port
--f, --log-format <string>     If a format is supplied an access log is written to stdout. If not, a statistics view is displayed. Use a
-                              preset ('none', 'dev','combined', 'short', 'tiny' or 'logstalgia') or supply a custom format (e.g. ':method ->
-                              :url').
--d, --directory <string>      Root directory, defaults to the current directory
--c, --compress                Enable gzip compression, reduces bandwidth.
--r, --refresh-rate <number>   Statistics view refresh rate in ms. Defaults to 500.
+*If a static file at the requested path exists (e.g. `/css/style.css`) then serve it, if it does not (e.g. `/login`) then serve the specified SPA and handle the route client-side.*
 
-Misc
--h, --help                    Print these usage instructions
---config                      Print the stored config
-```
+### Access Control
 
-From the folder you wish to serve, run:
+By default, access to all files is allowed (including dot files). Use `--forbid` to establish a blacklist:
 ```sh
-$ ws
+$ ws --forbid '*.json' '*.yml'
 serving at http://localhost:8000
 ```
 
-If you wish to serve a different directory, run:
-```sh
-$ ws -d ~/mysite/
-serving /Users/Lloyd/mysite at http://localhost:8000
-```
+### URL rewriting
+
+Your application requested `/css/style.css` but it's stored at `/build/css/style.css`. To avoid a 404 you need a rewrite rule:
 
-If you wish to override the default port (8000), use `--port` or `-p`:
 ```sh
-$ ws --port 9000
-serving at http://localhost:9000
+$ ws --rewrite '/css/style.css -> /build/css/style.css'
 ```
 
-To add compression, reducing bandwidth, increasing page load time (by 10-15% on my Macbook Air)
+Or, more generally (matching any stylesheet under `/css`):
+
 ```sh
-$ ws --compress
+$ ws --rewrite '/css/:stylesheet -> /build/css/:stylesheet'
 ```
 
-### Logging
-Passing a value to `--log-format` will write an access log to `stdout`.
+With a deep CSS directory structure it may be easier to mount the entire contents of `/build/css` to the `/css` path:
 
-Either use a built-in [morgan](https://github.com/expressjs/morgan) logger preset:
 ```sh
-$ ws --log-format short
+$ ws --rewrite '/css/* -> /build/css/$1'
 ```
 
-Or a custom [morgan](https://github.com/expressjs/morgan) log format:
+this rewrites `/css/a` as `/build/css/a`, `/css/a/b/c` as `/build/css/a/b/c` etc.
+
+
+#### Proxied requests
+
+If the `to` URL contains a remote host, local-web-server will act as a proxy - fetching and responding with the remote resource.
+
+Mount the npm registry locally:
 ```sh
-$ ws -f ':method -> :url'
+$ ws --rewrite '/npm/* -> http://registry.npmjs.org/$1'
 ```
 
-Or silence:
+Map local requests for repo data to the Github API:
 ```sh
-$ ws -f none
+$ ws --rewrite '/:user/repos/:name -> https://api.github.com/repos/:user/:name'
 ```
 
-## Storing default options
-To store per-project options, saving you the hassle of inputting them everytime, store them in the `local-web-server` property of your project's `package.json`:
+### Stored config
+
+Use the same port and blacklist every time? Persist it to `package.json`:
 ```json
 {
-  "name": "my-project",
-  "version": "0.11.8",
-  "local-web-server":{
-    "port": 8100
+  "name": "example",
+  "version": "1.0.0",
+  "local-web-server": {
+    "port": 8100,
+    "forbid": "*.json"
   }
 }
 ```
 
-Or in a `.local-web-server.json` file stored in the directory you want to serve (typically the root folder of your site):
+or `.local-web-server.json`
 ```json
 {
   "port": 8100,
-  "log-format": "tiny"
+  "forbid": "*.json"
 }
 ```
 
-Or store global defaults in a `.local-web-server.json` file in your home directory.
-```json
-{
-  "port": 3000,
-  "refresh-rate": 1000
-}
+local-web-server will merge and use all config found, searching from the current directory upward. In the case both `package.json` and `.local-web-server.json` config is found in the same directory, `.local-web-server.json` will take precedence. Command-line options take precedence over all.
+
+To inspect stored config, run:
+```sh
+$ ws --config
 ```
 
-All stored defaults are overriden by options supplied at the command line.
+### Logging
+By default, local-web-server outputs a simple, dynamic statistics view. To see traditional web server logs, use `--log-format`:
 
-To view your stored defaults, run:
+```sh
+$ ws --log-format combined
+serving at http://localhost:8000
+::1 - - [16/Nov/2015:11:16:52 +0000] "GET / HTTP/1.1" 200 12290 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2562.0 Safari/537.36"
+```
 
+The format value supplied is passed directly to [morgan](https://github.com/expressjs/morgan). The exception is `--log-format none` which disables all output.
+
+### Other usage
+
+#### Compression
+
+Serve gzip-compressed resources, where applicable
 ```sh
-$ ws --config
+$ ws --compress
 ```
 
-## mime-types
-You can set additional mime-type/extension mappings, or override the defaults by setting a `mime` value in your local config. This value is passed directly to [mime.define()](https://github.com/broofa/node-mime#mimedefine). Example:
+#### Disable caching
+
+Disable etag response headers, forcing resources to be served in full every time.
+```sh
+$ ws --no-cache
+```
+
+#### mime-types
+You can set additional mime-type/extension mappings, or override the defaults by setting a `mime` value in the stored config. This value is passed directly to [mime.define()](https://github.com/broofa/node-mime#mimedefine). Example:
 
 ```json
 {
-    "mime": {
-        "text/plain": [ "php", "pl" ]
-    }
+  "mime": {
+    "text/plain": [ "php", "pl" ]
+  }
 }
 ```
 
-## Use with Logstalgia
-local-web-server is compatible with [logstalgia](http://code.google.com/p/logstalgia/).
+#### Log Visualisation
+Instructions for how to visualise log output using goaccess, logstalgia or gltail [here](https://github.com/75lb/local-web-server/blob/master/doc/visualisation.md).
+
+## Install
+Ensure [node.js](http://nodejs.org) is installed first. Linux/Mac users may need to run the following commands with `sudo`.
 
-### Install Logstalgia
-On MacOSX, install with [homebrew](http://brew.sh):
 ```sh
-$ brew install logstalgia
+$ npm install -g local-web-server
 ```
 
-Alternatively, [download a release for your system from github](https://github.com/acaudwell/Logstalgia/releases/latest).
+This will install the `ws` tool globally. To see the available options, run:
+```sh
+$ ws --help
+```
+
+## Distribute with your project
+The standard convention with client-server applications is to add an `npm start` command to launch the server component.
+
+1\. Install the server as a dev dependency
 
-Then pipe the `logstalgia` output format directly into logstalgia for real-time visualisation:
 ```sh
-$ ws -f logstalgia | logstalgia -
+$ npm install local-web-server --save-dev
+```
+
+2\. Add a `start` command to your `package.json`:
+
+```json
+{
+  "name": "example",
+  "version": "1.0.0",
+  "local-web-server": {
+    "port": 8100,
+    "forbid": "\\.json$"
+  },
+  "scripts": {
+    "start": "ws"
+  }
+}
 ```
 
-![local-web-server with logstalgia](http://75lb.github.io/local-web-server/logstagia.gif)
+3\. Document how to build and launch your site
 
-## Use with glTail
-To use with [glTail](http://www.fudgie.org), write your log to disk using the "default" format:
 ```sh
-$ ws -f default > web.log
+$ npm install
+$ npm start
+serving at http://localhost:8100
 ```
 
-Then specify this file in your glTail config:
+## API Reference
+
+<a name="module_local-web-server"></a>
+## local-web-server
+<a name="exp_module_local-web-server--localWebServer"></a>
+### localWebServer([options]) ⏏
+Returns a Koa application
 
-```yaml
-servers:
-    dev:
-        host: localhost
-        source: local
-        files: /Users/Lloyd/Documents/MySite/web.log
-        parser: apache
-        color: 0.2, 0.2, 1.0, 1.0

+
+# local-web-server
+A simple web-server for productive front-end development.
+
+**Requires node v4.0.0 or higher**.
+
+## Synopsis
+For the examples below, we assume we're in a project directory looking like this:
+
+```sh
+.
+├── css
+│   └── style.css
+├── index.html
+└── package.json
+```
+
+All paths/routes are specified using [express syntax](http://expressjs.com/guide/routing.html#route-paths).
+
+### Static site
+
+Fire up your static site on the default port:
+```sh
+$ ws
+serving at http://localhost:8000
+```
+
+### Single Page Application
+
+You're building a web app with client-side routing, so mark `index.html` as the SPA.
+```sh
+$ ws --spa index.html
+```
+
+By default, typical SPA urls (e.g. `/user/1`, `/login`) would return `404 Not Found` as a file does not exist with that path. By marking `index.html` as the SPA you create this rule:
+
+*If a static file at the requested path exists (e.g. `/css/style.css`) then serve it, if it does not (e.g. `/login`) then serve the specified SPA and handle the route client-side.*
+
+### Access Control
+
+By default, access to all files is allowed (including dot files). Use `--forbid` to establish a blacklist:
+```sh
+$ ws --forbid '*.json' '*.yml'
+serving at http://localhost:8000
+```
+
+### URL rewriting
+
+Your application requested `/css/style.css` but it's stored at `/build/css/style.css`. To avoid a 404 you need a rewrite rule:
+
+```sh
+$ ws --rewrite '/css/style.css -> /build/css/style.css'
+```
+
+Or, more generally (matching any stylesheet under `/css`):
+
+```sh
+$ ws --rewrite '/css/:stylesheet -> /build/css/:stylesheet'
+```
+
+With a deep CSS directory structure it may be easier to mount the entire contents of `/build/css` to the `/css` path:
+
+```sh
+$ ws --rewrite '/css/* -> /build/css/$1'
+```
+
+this rewrites `/css/a` as `/build/css/a`, `/css/a/b/c` as `/build/css/a/b/c` etc.
+
+
+#### Proxied requests
+
+If the `to` URL contains a remote host, local-web-server will act as a proxy - fetching and responding with the remote resource.
+
+Mount the npm registry locally:
+```sh
+$ ws --rewrite '/npm/* -> http://registry.npmjs.org/$1'
+```
+
+Map local requests for repo data to the Github API:
+```sh
+$ ws --rewrite '/:user/repos/:name -> https://api.github.com/repos/:user/:name'
+```
+
+### Stored config
+
+Use the same port and blacklist every time? Persist it to `package.json`:
+```json
+{
+  "name": "example",
+  "version": "1.0.0",
+  "local-web-server": {
+    "port": 8100,
+    "forbid": "*.json"
+  }
+}
+```
+
+or `.local-web-server.json`
+```json
+{
+  "port": 8100,
+  "forbid": "*.json"
+}
+```
+
+local-web-server will merge and use all config found, searching from the current directory upward. In the case both `package.json` and `.local-web-server.json` config is found in the same directory, `.local-web-server.json` will take precedence. Command-line options take precedence over all.
+
+To inspect stored config, run:
+```sh
+$ ws --config
+```
+
+### Logging
+By default, local-web-server outputs a simple, dynamic statistics view. To see traditional web server logs, use `--log-format`:
+
+```sh
+$ ws --log-format combined
+serving at http://localhost:8000
+::1 - - [16/Nov/2015:11:16:52 +0000] "GET / HTTP/1.1" 200 12290 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2562.0 Safari/537.36"
+```
+
+The format value supplied is passed directly to [morgan](https://github.com/expressjs/morgan). The exception is `--log-format none` which disables all output.
+
+### Other usage
+
+#### Compression
+
+Serve gzip-compressed resources, where applicable
+```sh
+$ ws --compress
+```
+
+#### Disable caching
+
+Disable etag response headers, forcing resources to be served in full every time.
+```sh
+$ ws --no-cache
+```
+
+#### mime-types
+You can set additional mime-type/extension mappings, or override the defaults by setting a `mime` value in the stored config. This value is passed directly to [mime.define()](https://github.com/broofa/node-mime#mimedefine). Example:
+
+```json
+{
+  "mime": {
+    "text/plain": [ "php", "pl" ]
+  }
+}
+```
+
+#### Log Visualisation
+Instructions for how to visualise log output using goaccess, logstalgia or gltail [here](https://github.com/75lb/local-web-server/blob/master/doc/visualisation.md).
+
+## Install
+Ensure [node.js](http://nodejs.org) is installed first. Linux/Mac users may need to run the following commands with `sudo`.
+
+```sh
+$ npm install -g local-web-server
+```
+
+This will install the `ws` tool globally. To see the available options, run:
+```sh
+$ ws --help
+```
+
+## Distribute with your project
+The standard convention with client-server applications is to add an `npm start` command to launch the server component.
+
+1\. Install the server as a dev dependency
+
+```sh
+$ npm install local-web-server --save-dev
+```
+
+2\. Add a `start` command to your `package.json`:
+
+```json
+{
+  "name": "example",
+  "version": "1.0.0",
+  "local-web-server": {
+    "port": 8100,
+    "forbid": "\\.json$"
+  },
+  "scripts": {
+    "start": "ws"
+  }
+}
+```
+
+3\. Document how to build and launch your site
+
+```sh
+$ npm install
+$ npm start
+serving at http://localhost:8100
+```

+
+# local-web-server
+Fires up a simple, CORS-enabled, static web server on a given port. Use for local web development or file sharing (directory browsing enabled).
+
+![local-web-server](http://75lb.github.io/local-web-server/ws.gif)
+
+## Install
+Ensure [node.js](http://nodejs.org) is installed first. Linux/Mac users may need to run the following commands with `sudo`.
+
+### Globally
+```sh
+$ npm install -g local-web-server
+```
+
+### Bundled with your project
+```sh
+$ npm install local-web-server --save-dev
+```
+
+Then add an `start` script to your `package.json` (the standard npm approach):
+```json
+{
+  "name": "my-web-app",
+  "version": "1.0.0",
+  "scripts": {
+    "start": "ws"
+  }
+}
+```
+This simplifies a rather specific-looking instruction set like:
+
+```sh
+$ npm install
+$ npm install -g local-web-server
+$ ws
+```
+
+to the following, server implementation and launch details abstracted away:
+```sh
+$ npm install
+$ npm start
+```
+
+## Usage
+```
+Usage
+$ ws <server options>
+$ ws --config
+$ ws --help
+
+Server
+-p, --port <number>           Web server port
+-f, --log-format <string>     If a format is supplied an access log is written to stdout. If not, a statistics view is displayed. Use a
+                              preset ('none', 'dev','combined', 'short', 'tiny' or 'logstalgia') or supply a custom format (e.g. ':method ->
+                              :url').
+-d, --directory <string>      Root directory, defaults to the current directory
+-c, --compress                Enable gzip compression, reduces bandwidth.
+-r, --refresh-rate <number>   Statistics view refresh rate in ms. Defaults to 500.
+
+Misc
+-h, --help                    Print these usage instructions
+--config                      Print the stored config
+```
+
+From the folder you wish to serve, run:
+```sh
+$ ws
+serving at http://localhost:8000
+```
+
+If you wish to serve a different directory, run:
+```sh
+$ ws -d ~/mysite/
+serving /Users/Lloyd/mysite at http://localhost:8000
+```
+
+If you wish to override the default port (8000), use `--port` or `-p`:
+```sh
+$ ws --port 9000
+serving at http://localhost:9000
+```
+
+To add compression, reducing bandwidth, increasing page load time (by 10-15% on my Macbook Air)
+```sh
+$ ws --compress
+```
+
+### Logging
+Passing a value to `--log-format` will write an access log to `stdout`.
+
+Either use a built-in [morgan](https://github.com/expressjs/morgan) logger preset:
+```sh
+$ ws --log-format short
+```
+
+Or a custom [morgan](https://github.com/expressjs/morgan) log format:
+```sh
+$ ws -f ':method -> :url'
+```
+
+Or silence:
+```sh
+$ ws -f none
+```
+
+## Storing default options
+To store per-project options, saving you the hassle of inputting them everytime, store them in the `local-web-server` property of your project's `package.json`:
+```json
+{
+  "name": "my-project",
+  "version": "0.11.8",
+  "local-web-server":{
+    "port": 8100
+  }
+}
+```
+
+Or in a `.local-web-server.json` file stored in the directory you want to serve (typically the root folder of your site):
+```json
+{
+  "port": 8100,
+  "log-format": "tiny"
+}
+```
+
+Or store global defaults in a `.local-web-server.json` file in your home directory.
+```json
+{
+  "port": 3000,
+  "refresh-rate": 1000
+}
+```
+
+All stored defaults are overriden by options supplied at the command line.
+
+To view your stored defaults, run:
+
+```sh
+$ ws --config
+```
+
+## mime-types
+You can set additional mime-type/extension mappings, or override the defaults by setting a `mime` value in your local config. This value is passed directly to [mime.define()](https://github.com/broofa/node-mime#mimedefine). Example:
+
+```json
+{
+    "mime": {
+        "text/plain": [ "php", "pl" ]
+    }
+}
+```
+
+## Use with Logstalgia
+local-web-server is compatible with [logstalgia](http://code.google.com/p/logstalgia/).
+
+### Install Logstalgia
+On MacOSX, install with [homebrew](http://brew.sh):
+```sh
+$ brew install logstalgia
+```
+
+Alternatively, [download a release for your system from github](https://github.com/acaudwell/Logstalgia/releases/latest).
+
+Then pipe the `logstalgia` output format directly into logstalgia for real-time visualisation:
+```sh
+$ ws -f logstalgia | logstalgia -
+```
+
+![local-web-server with logstalgia](http://75lb.github.io/local-web-server/logstagia.gif)
+
+## Use with glTail
+To use with [glTail](http://www.fudgie.org), write your log to disk using the "default" format:
+```sh
+$ ws -f default > web.log
+```
+
+Then specify this file in your glTail config:
+
+```yaml
+servers:
+    dev:
+        host: localhost
+        source: local
+        files: /Users/Lloyd/Documents/MySite/web.log
+        parser: apache
+        color: 0.2, 0.2, 1.0, 1.0
+```
