h4. Running with built in server

* @cd elasticsearch-head@
* @npm install@

* @open@ "http://localhost:9100/":http://localhost:9100/

This will start a local webserver running on port 9100 serving elasticsearch-head
* Best option if you are likely to connect to serveral different clusters

h4. Alternatives

h5. Running from the filesystem

elastisearch-head is a standalone webapp written in good-ol' html5. This means, you can put it up on any webserver, run it directly from the filesystem, use it on an ipad, or put it on a floppy disk and carry it with you.

h4. URL Parameters

Parameters may be appended to the url set some initial state eg. @head/index.html?base_uri=http://node-01.example.com:9200@

* @base_uri@ force elasticsearch-head to connect to a particular node.
* @dashboard@ experimental feature to open elasticsearch-head in a mode suitable for dashboard / radiator. Accepts one parameter @dashboard=cluster@ 
* @auth_user@ adds basic auth credentials to http requests ( requires "elasticsearch-http-basic":https://github.com/karussell/elasticsearch-http-basic plugin or a reverse proxy )
* @auth_password@ basic auth password as above (note: without "additional security layers":http://security.stackexchange.com/questions/988/is-basic-auth-secure-if-done-over-https, passwords are sent over the network *in the clear* )
