#Nodejs readline code#
At the end, your TypeScript code once compiled will generate NodeJS code. The complete sample program to demonstrate CRUD operations in Nodde.js and MongoDB integration example is given below. FredDanna You're right but TypeScript is just a language which adds a layer over NodeJS code to add things like type checks. Rl.question("What is your name? ", function(answer), bookDeleteHandler) Asking for user input and providing a callback to deal with the user input Initializing the reading interface to read from The below code demonstrates how one can read from command line in Node.js On similar lines, there is a module in Node.js called readline which provides APIs to read from different input streams. Node.js organizes the code into different Node packages ( think of them as packages in Java) and we can use those packages/modules by using the require function. Reading user input from command line in Node.js Node.js and MongoDB Integration Example.Deleting records from MongoDB in Node.js.
Listing/Reading records from MongoDB in Node.js.Optionally, interface specifies a readline.Interface instance for which autocompletion is disabled when copy-pasted input is detected. Inserting record into MongoDB in Node.js interface readline.InterfaceConstructor The readline.emitKeypressEvents() method causes the given Readable stream to begin emitting 'keypress' events corresponding to received input. The node:readline module provides an interface for reading data from a Readable stream (such as process.stdin ) one line at a time.Reading user input from command line in Node.js.This post is divided into following parts: PrimeFaces + Spring Data + MongoDB Integration.
In my next article, I will write about using Mongoose to facilitate the database modeling with Node.js. At the end of this post, I have given the complete example code for Node.JS and MongoDB integration example. The book has the following attributes: name, isbn, authors, page count. To demonstrate CRUD operations I am picking a common example of storing, retrieving, updating and delete a book from the DB. If you have any questions, please write it in the comments section or post it in our facebook page. And this example is going to be command line based and hence we will be taking user input from command line. The programming language we would use for this is Javascript based Node.js ( Read : Introduction to Node.js) framework and MongoDB as the NoSQL database.
#Nodejs readline update#
CRUD stands for Create Read Update Delete. In this post we will look at how we can implement CRUD operations using Node.js and MongoDB as the database.
