Creating your first Node.js application with Node-Data

In this blog, we will learn how to create a Node.js application with Node-Data. Let’s assume that you are building an application for blogs and you want to create REST APIs which can be used by a front-end/mobile application.

• • Create blogs into database
  • Update blogs into database
  • Delete blogs from database
  • Find and fetch a blog using any existing blog ID from the database

Prerequisites:

• MongoDB is installed and server is running on a default port
• Node 6.9.0 is installed
• IDE (Eg: VS Code)
• REST client (Eg: Postman, Curl) for testing

Installation:

1. git clone https://github.com/ratneshsinghparihar/nodedata-demo-sample.git
2. cd nodedata-demo-sample/Demo-Sample
3. npm install

Code changes

• Add a model blogmodel.ts inside the Models folder.
• Add a repository blogmodelrepository.ts inside the Repositories folder.

• Model with @document to create a document inside Blogs collection.
• A repository with the blog name will create all the necessary REST end points.

Testing

1. npm start
2. Post a JSON {“name”: “testBlog”} to http://localhost:9999/data/blogs
3. Hit the api to get data(http://localhost:9999/data/blogs)
4. Hit the api with put method http://localhost:9999/data/blogs/{{blogId}} with body {“name”: “testBlog1”}
5. Hit the api with delete method http://localhost:9999/data/blogs/{{blogId}}
