These routes will call functions from data.js module. Now we need to add various routes in app.js. So far we have created business logic to be exposed as REST API. Putting all together data.js which contains logic for CRUD would be as below, Just we created CRUD operation which we will expose as REST API. ProductToUpdate.productStock = data.productStock ProductToUpdate.productPrice = data.productPrice ProductToUpdate.productName = data.productName Once product is updated successfully we are sending updated product JSON object in HTTP response.Įxports.updateProduct = function(req,res) Keep in mind that in real project and API this logic should be better.
#Visual studio node update#
After that I am just putting some logic to update item in products array. Once we have id to update a product, we will read data to be updated in req.body. To update record we need to read query parameter coming in URL as HTTP request. Once product is deleted successfully we are sending updated product JSON object in HTTP response.ĮleteProduct = function(req,res) Once we have id to delete a product, I am just putting some logic to delete it from products array. To delete record we need to read query parameter coming in URL as HTTP request. After reading request body we are just pushing data in array using push method. Client will append JSON data to get added in product array in request body. To add record we need to read data coming in HTTP request. In this case we are sending JSON object product as HTTP response. We send data in HTTP response with res.send. If you notice function is taking two parameters req and res.
Let us start with writing function to return products. To start with I have created an array as below, In real projects you may want to perform these operations on database. Keep in mind that we are going to expose CRUD operation as REST API on a JavaScript Array. īefore you work with data.js I recommend you to read below postįirst we are going to create data and CRUD operation on that.
#Visual studio node free#
You are free to give any file name, I am giving data.js. Once project is created right click on the public\javascripts folder and add a new JavaScript file. Getting started with Node.js development in Visual StudioĪfter reading above article when you are done with setting up Visual Studio for Node.js go ahead and create a Node Application by selecting Blank Express Application template from JavaScript language section I am going to use Visual Studio to create Node Application and before you move ahead in this post, recommend you to read In this post I am not going to explain, what is REST? I assume you are already aware of REST concepts hence on this post to create REST API on Node.js which will perform CRUD operations.
