Node Js Training overview:
Users use the client server architecture to interact with the client machines on any electronic devices. To understand the user makes a request that will be taken by the server and the server will send back the response.
Client Server Architecture – (Node Js Training):
From the client the request will come and the every time it appears it sends to the server. Every time the server takes the new request the server maps a new thread from the thread group.
- Here each request will have individual thread so; the requests will be equal to the threads. This is a Multi thread model. This will be the lengthy process, so we have the Single Thread Model.
- In the multi thread model, this functions like when number of threads are working only one thread will work currently while other threads are blocked. If suppose there are four responses A is working then B, C and D will be blocked.
- If B is working then A, C and D will be blocked. Only one thread will be working, remaining will be blocked.
Single Thread Model:
In the single thread model, the users will create events, and then they reside in the event queue. These events will be processed in the Event loop which is the single thread mechanism.
This event loop will take the event from the event queue and that will be sent to the thread pool, these allocations will be divided by the operation performed by the event.
Asynchronous Function in Node.js:(Node Js Training)
In this, there are two blocks that is Caller and Recipient. There will be interaction between this caller and recipient like request, response and callback function also.
- The caller will request and the recipient will respond. There is also a callback function. These functions are non blocking functions. Here the notification mechanism is called Callback function.
- The Node js is with the java script engine so it is very fast.
- There are many applications that people use nowadays like desktops, mobiles, laptops, tablets, Cloud back-end, Web front-end API services and IoT devices.
- Node Js is the best platform for these applications to be performed.
NPM: (Node Package Modules or Manager)
It is the important part of node js. In this the modules can be installed in the modules folder that is NPM install express, and it can be installed by the browser directly into your system then you can access from anywhere.
In this no error will be occurring, whereas java uses stack for each and it will use memory that will become very slow process. In the Node Js Training you can know more about the courses helpful for your business.
Here Node Js is mostly focused on the input and output interactions. It will give the interaction with the file system. So you can read, write or perform any other action, with the IoT you can also it will be beneficial.
- Through the node package management the work is easy not much complicated and doesn’t require knowledge of C, C++, etc you can do work easily with the Node Js. Node Js is a real time interaction. Through the e-learning also you can learn the Node Js Training.
- These are the user applications that run the service in the web browser or with the mobile devices. These need some services that are like back-end server for giving the notifications, send mails, and for workflows.
Advantages: (Node Js Training)
- This can be started easily, it is used in many big applications and it is easy to handle large amount of work.
- It has the largest open source library.
- For example the Microsoft uses the Chakra, Firefox uses the SpiderMonkey and chrome uses the v8.
- In this architecture the components work like that in the asynchronous manner that is non blocking architecture, the work goes on simultaneously.
- In the synchronous architecture means blocking architecture, it works one after other requests. These are built with ASP.Net or RAILS.
- You should not use node for the intensive applications like video encoding etc. The node is a single thread application, while performing the calculations it should wait for the process to complete so, node should not be used for the CPU-Intensive applications.
RESTful API’s: (Node Js Training)
This follows the Client Server Architecture. The client will be the front-end part and the server will be the back-end part that saves the data. Under the server, the HTTP protocols are used so that the client can directly call the services.
- Here REST expands for Representational State Transfer. This Rest is used for building the HTTP services. There are some simple HTTP protocols like, Create, Read, Update and Delete data, combine these are known as CRUD Operations.
- Here are some HTTP Methods like GET, POST, PUT and DELETE the data these are used for the standard HTTP methods, node js course can be useful for you.
What is Reactjs?
- React js on other hand can be extended to build single page applications and there certainly is nothing wrong with that.
- In that case it has really a lot of similarities with angular 2 but need to import some extra packages it’s not all built in to core reactjs because core reactjs is about building views or parts of views single components or widgets which can then dump on to views.
- And then this data was passed to the dispatcher then to the store and then ultimately came to the view.
- Now Google is the part where the user is actually interfacing with applications and being user whatever see in the browser as a webpage is the view.
- If there is a change in data from any of these sources from the back-end in order to reflect those changes on the view after the refresh that entire page and then it’s seen by the user.
- The drawbacks of using this is use the DOM stands for Document Object Model, it is an object that is created by the browser each time of web pages loaded, it can dynamically add or remove elements from a web page at the back-end but each time it did that the browser had to create a new DOM for the same web-page this let to more memory consumption which ultimately made the applications slow. You will know the components and its brief information in the Reactjs training.
Angularjs: (With Node Js training):
- Angularjs is appropriate for making single page Application, yet we can likewise use for multi paged dynamic web application. You will know the components and its brief information in the Angularjs training.
Node Js Global’s: (Node Js Training)
The console object is called as the Global object. It can be accessed anywhere in any files. Let’s take an example; setTimeout();
- In the Node.js has global as the global object all the variables and the functions that are defined globally we can access them by this window object. So, we can call this function like window.console.log or console.log.
- In the node global.console or global.setTimeout(). These are not defined; it gives the result as undefined. So, this is up to this page itself, they are not added to the global object. This is because the node modular system, node js tutorial are also provided.
Modules: (Node Js Training)
In the core of the node, we have the concept of modules. Each file in the node application is considered as the module. The functions and variables that is undefined outside that module. So, if you want to get defined then you need to export it and make it as the public.
- ExpressJs is web application framework for the node. This is flexible and good for the Web API’s. And also these are popular in some services.
- We can download the NPM directly by the browser by this command “npm install express”.
- If you want to download the latest version then you can mention the version number.
Simple API server will accept HTTP protocols. First the express library is required. Then we get a function and when we run that function then we get an instance of the application that will be stored in the application variable.
- The HTTP functions give the path to the route. For running the ExpressJs we need nodejs and the NPM.
