- #redirect Getting_started_with_JavaScript
- Getting started with !JavaScript and the CouchDB API.
  
- == Simple Wrapper ==
- 
- There is a simple !JavaScript wrapper around CouchDB included in the distribution. When you install the server it is installed as http://localhost:5984/_utils/script/couch.js. You can see examples of its use in ''couch_tests.js'':
- 
- {{{
-  var nc = {_id:"NC", cities:["Charlotte", "Raleigh"]};
-  var ma = {_id:"MA", cities:["Boston", "Lowell", "Worcester", "Cambridge", "Springfield"]};
-  var fl = {_id:"FL", cities:["Miami", "Tampa", "Orlando", "Springfield"]};
- 
-  db.save(nc);
-  db.save(ma);
-  db.save(fl);
- 
-  ...
- 
-  var nc_cities = db.open('NC').cities;
- }}}
- 
- Obviously the ''couch.js'' API is by no means final since CouchDB itself is still in flux.
- 
- == Rolling Your Own ==
- 
- CouchDB speaks JSON. JSON means !JavaScript Object Notation. CouchDB also speaks Plain Old HTTP, so getting going with !JavaScript is a walk in the park with the XML!HttpRequest object:
- 
- {{{
- // instantiate a new XMLHttpRequest object
- var req = new XMLHttpRequest()
- // Open a GET request to "/all_dbs"
- req.open("GET", "/_all_dbs")
- // Send nothing as the request body
- req.send("")
- // Get the response
- req.responseText
- ["some_database", "another_database"]
- }}}
- 
- Going from here is just a matter using the normal CouchDB HttpRestApi to get what you want.
- 
- There is numerous javascript libraries out there that wraps up both XML!HttpRequest and JSON in possibly nicer APIs, including:
