Overview of NodeJs online training:
What is NodeJs?
Learn how NodeJs works in our NodeJs online training:
Let’s see how NodeJs works. NodeJs applications are highly scalable, data-intensive and real-time apps. This is just because of non-blocking or asynchronous nature of node. Now let’s have a look at what exactly asynchronous means. A single thread allocates to handle the request. So a single thread is used to handle multiple requests in contrasting to non-blocking architecture. This process is known as asynchronous architecture or non-blocking architecture. This is all about the architecture of the NodeJs. We will be covering more about this topic in our NodeJs online training.
Learn features of NodeJs in our NodeJs training:
- For example, 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, a node should not be used for the CPU-Intensive applications.
Learn about the client-server model in our NodeJs online course:
Let’s take a look at what exactly the client-server model is. The client-server model is nothing but architecture on the web that splits the computers into two sections and they are clients and servers. Computers that ask for requests are known as clients and computer that server clients are known as servers. This client-server model works through a request-response cycle via HTTP messages and it is based on a centralized architecture. The client-server model is a way for computers to communicate via the web. This is all about the client-server model architecture. We will be covering more about this topic in our NodeJs online training.
Learn about Blocking and Non-Blocking topic in our NodeJs online training:
Let’s have a look at what blocking and non-blocking models are. Blocking (or asynchronous) and non-blocking look quite similar in nature but there is a subtle difference here. First of all, in the blocking model, our API will return immediately after calling it. In the background, it will start a process to fulfill the request and once the process is completed and our work is done. We have already known that our main thread does not wait for that process to finish. Let’s see what exactly non-blocking nature of node. In non-blocking, if the API cannot complete the work, then it will return an error. Depending upon the response, you can decide whether you want to make another call to the same API or not. You can create a waiting mechanism in non-blocking operations. This is just basic information about blocking and non-blocking nature of node. We will be covering more about this topic in our NodeJs online course.
Learn about NodeJs modules in our NodeJs training:
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 such as 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 the other hand, can be extended to build single page applications and there certainly is nothing wrong with that.
- In that case, it was really a lot of similarities with angular 2 but need to import some extra packages it’s not all built into 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 a 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 using 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 a 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 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 is 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 is 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 are 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 a 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. The 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.
