    We have created a Proof of Concept with Javascript based web server, where we have focused on dealing with NoSql (CouchDB) with javascript based framework Node.js and angular.js on client side.

  • Here we have made our first REST based web service and tested whether the express.js is running.Our sample api will be http://127.0.0.1:1212/api or we have created another REST api to get all username from user collection and so we have done the cradle query.
  • Below is the code in Angular Controller

    We have referred the Angular Application in above code

    We have used the ng-repeat tag to take the users data model from REST communication and shown in HTML

    We have used the ng-submit tag to send the user data model from REST communication and sent to node server to save in CouchDB.

We posted the article on [Single Page Application with Angular.js, Node.js and CouchDB Cradle Module with Express 3. Current post is a way to migrate the same with Express 4.

This article describes a way to make a web application with Javascript based Web Server with CouchDB with Angular.js and Node.js.

We have created a Proof of Concept with Javascript based web server, where we have focused on dealing with NoSql (CouchDB) with javascript based framework Node.js and angular.js on client side.

Here we have initialised the express.js within javascript variables in respect of Node.js concept.

Here we have initialised the express web server in app variable.

Here we have made the connection to the couchdb database using the Node.js cradle module extension library.

Here we have made the configuration related to express.js which is very much different from Express 3.

This makes a little sense how the Express 3 is migrated to Express 4.

In Express 4 app.use(app.router); is removed. Instead it is added with the Rest services.The way of configuration is also changed as well as the changes reflected in use of bodyParser() ,methodOverride() ,methodOverride() ,errorHandler({…}).

Here we have created another REST api to get all username from user collection and so we have done the cradle query.

This view creation is to be executed, before running the Angular Client Application to get specific set of data from couchdb.

To run this view creation, we should put

in the local.ini file of <>/etc/couchdb folder to execute this map function without being the admin user.

and the sample api will be – http://127.0.0.1:1212/getangularusers (Get Method).

Next we have made a POST request to create an user via REST calling.

We have made the server to listen at 1212 port.

Now run node appcouchdbangular.js from command shell. This is our node.js specific code file.

We have used the ng-submit tag to send the user data model from REST communication and sent to node server to save in CouchDB.
