# local-web-server
The development web server for productive front-end and full-stack Javascript engineers. Built on [lws](https://github.com/lwsjs/lws).
**Features**
- Fast and lightweight.
- Use the built-in features, a subset of the built-ins or your own feature stack
- Configurable with sensible defaults.
- Configure by constructor option, command-line option, stored config or all three.
- HTTP or HTTPS ([HTTP2](https://github.com/nodejs/http2) will be added once ready)
- URL rewriting
- Local rewrites for quick experimentation (e.g. from `/img/logo.svg` to `/img/new-logo.svg`)
- Rewrite to remote resources (e.g. from `/api/*` to `https://example-api.pl/api/$1`). *Note: ignores remote server's CORS policy, which during development is typically what you want*.
- Optimisal caching by default.
- Efficient, predictable, entity-tag-powered conditional request handling (no need to 'Disable Cache' in DevTools, slowing page-load down)
- Configurable log output, compatible with [Goaccess, Logstalgia and glTail](https://github.com/lwsjs/local-web-server/blob/master/doc/visualisation.md)
- Configurable CORS rules. All origins allowed by default.
**Links to demoes and how-tos**
Things you can build:
- Simple static website
- Single Page Application
- Works well with React, Angular or vanilla JS.
- Real or mock web services
- e.g. a RESTful API or microservice
- Mocks are defined with config (static), or code (dynamic).
- Websocket server
## Synopsis
local-web-server is a command-line tool. To serve the current directory, run `ws`.
<pre><code>$ ws --help
<strong>local-web-server</strong>
A convenient local web server to support productive, full-stack Javascript
development.
<strong>Synopsis</strong>
$ ws [--verbose] [--config-file file] [&lt;server options&gt;] [&lt;middleware options&gt;]
$ ws --config
$ ws --help
$ ws --version
<strong>General</strong>
-h, --help Print these usage instructions.
--config Print the active config.
-c, --config-file file Config filename to use, defaults to "lws.config.js".
-v, --verbose Verbose output.
--version Print the version number.
<strong>Server</strong>
-p, --port number Web server port.
--hostname string The hostname (or IP address) to listen on. Defaults to 0.0.0.0.
--stack feature ... Feature stack.
--key file SSL key. Supply along with --cert to launch a https server.
--cert file SSL cert. Supply along with --key to launch a https server.
--https Enable HTTPS using a built-in key and cert, registered to the domain
127.0.0.1.
<strong>Middleware</strong>
-f, --log.format string If a format is supplied an access log is written to stdout. If not, a dynamic
statistics view is displayed. Use a preset ('none', 'dev','combined',
'short', 'tiny', 'stats', or 'logstalgia') or supply a custom format (e.g.
':method -> :url').
--cors.origin Access-Control-Allow-Origin value. Default is request Origin header.
--cors.allow-methods Access-Control-Allow-Methods value. Default is
"GET,HEAD,PUT,POST,DELETE,PATCH"
-r, --rewrite expression ... A list of URL rewrite rules. For each rule, separate the 'from' and 'to'
routes with '->'. Whitespace surrounded the routes is ignored. E.g. '/from ->
/to'.
-b, --forbid path ... A list of forbidden routes.
-n, --no-cache Disable etag-based caching - forces loading from disk each request.
-z, --compress Serve gzip-compressed resources, where applicable.
--compress.threshold number Minimum response size in bytes to apply compression. Defaults to 1024 bytes.
--spa file Path to a Single Page App, e.g. app.html.
--spa.asset-test RegExp A regular expression to identify an asset file. Defaults to "\.".
-d, --directory path Root directory, defaults to the current directory.
--static.maxage number Browser cache max-age in milliseconds.
--static.defer If true, serves after `yield next`, allowing any downstream middleware to
respond first.
--static.index path Default file name, defaults to `index.html`.
--index.root path Index root directory, defaults to --directory or the current directory.
--index.hidden Show hidden files.
--index.view name Display mode, either `tiles` or `details`. Defaults to tiles.
