海外TECH	DEV Community	What is Node.js?: A Complete Guide	https://dev.to/amplication/what-is-nodejs-a-complete-guide-527a	What is Node js A Complete GuideNode js is a robust runtime environment that has revolutionized how developers build server side applications It allows developers to use JavaScript on both the frontend and backend making it the perfect choice for building scalable high performance applications According to the Stack Overflow Developer Survey Node js was the most used web technology among professional developers with more than of votes and it ranked th in the most loved technologies list Therefore Node js can be considered a future proof technology that every developer should know This article will provide an in depth overview of Node js including its features use cases advantages disadvantages step by step guides for setting up Node js with different operating systems and answers to some of the most frequently asked questions about Node js What is Node js Node js is one of the most popular runtime environments for JavaScript web servers and other network applications in general It is open source cross platform and known for its single threaded asynchronous event driven concurrency model It was introduced in and revolutionalized the development world since it allowed developers to run JavaScript outside web browsers Node js is written in C C and JavaScript The core components of Node js the V engine and the libuv library are written in C and C respectively since these languages provide low level access to system resources making them well suited for building high performance and efficient applications JavaScript is mainly used to write the application logic How Node js WorksWhen you run a JavaScript program in Node js the V engine will first parse the code to build an Abstract Syntax Tree AST Side note ASTs are a foundational concept in Amplication for generating code The interpreter takes the AST generated by the V parser and generates bytecode from the AST Lastly the compiler compiles the bytecode into binary machine code that matches the CPU architecture of the running host Although Node js is single threaded it uses an event driven non blocking I O model to handle multiple requests simultaneously without blocking others This behavior is achieved through the event loop As the name implies the event loop is a loop that runs continuously and waits for events to occur When an event occurs the event loop will add the event to an event queue If there are no other pending events in the queue the event loop will execute the event and remove it from the event queue If there are any other events in the queue they will be processed one at a time in a non blocking manner For example consider the below example with two setTimeout functions console log Starting setTimeout function console log Timer finished setTimeout function console log Timer finished console log Stopping Let s break down the execution of the above example into steps to understand better how the event loop works The script will start and log Starting in the console The first setTimeout function is called and it will schedule the execution of the function passed to it after a delay of seconds The second setTimeout function will then be called and schedule the execution of the function passed to it after a delay of seconds The script will log Stopping in the console Once the main thread execution finishes Node js starts processing the event loop and checks if there are any pending callbacks in the event queue In this case two callbacks are pending in the queue with timer events The event loop runs the callback for the second setTimeout function logs Timer finished in the console and removes the event from the queue The event loop then runs the callback for the first setTimeout function logs Timer finished to the console and removes the event from the queue Once the event queue is empty the event loop will again start waiting for new events to add to the event queue The event loop will constantly check the event queue for completed events When an event s delay time has passed it is moved from the event queue to the call stack for execution In this case the second setTimeout function has a shorter delay time than the first So it will be moved from the event queue to the call stack before the first setTimeout function That s why the output of the example will look like the below StartingStoppingTimer finishedTimer finished What Are the Features of Node js Asynchronous I O Node js uses an event driven non blocking I O model to handle multiple requests simultaneously without blocking the execution of other requests Cross platform Supports Windows macOS and Linux operating systems Fast startup time Unlike other runtime environments Node js has a fast startup time So developers can quickly test and iterate on their code Web socket support Built in support for web sockets allowing bi directional communication Large ecosystem Many open source modules and packages are available in NPM No buffering Node js does not buffer data Data is processed as soon as received resulting in faster response times and reduced latency What is Node js used for Node js is a multi purpose runtime environment that developers can use in a variety of ways APIs Highly scalable and performance oriented APIs for web and mobile applications Real time applications Ideal for real time applications like chat apps and online gaming platforms Microservice Developers can easily design microservice architectures with Node js Furthermore they can use tools like Amplication to generate fully functional services based on Typescript and Node js with popular technologies such as but not limited to NestJS Prisma PostgreSQL GraphQL and MongoDB Cross platform application development Can be used for desktop application development with Electron IoT Perfect for building applications requiring real time communications Single page applications Works well with frontend frameworks like Angular React and Vue js Pros of Node js DevelopmentNode js is excellent for high performance applications since it is built on the V JavaScript engine Highly scalable since its event loop mechanism helps to process requests non blocking Simplifies web development by allowing developers to use JavaScript for both frontend and backend development Huge active user community Cost effective since Node js is open source Easy integrations with other development tools and technologies like Express AWS Socket IO MongoDB etc Cons of Node js DevelopmentUsing too many callbacks to write asynchronous code can cause callback hell Node js is not designed to handle CPU intensive tasks like video encoding data encryption or scientific computing Developers need to take extra measures to increase the security of their applications There are difficulties in debugging due to asynchronous control flow NPM dependencies are hard to manage some packages are not stable or not well documented or might have security issues In addition project size grows unexpectedly with nested dependencies How to Install Node jsInstalling Node js is simple and one of the first things developers should do when setting up their machines Step Download the latest LTS Node js version from their webpage Make sure to select the appropriate installer based on your operating system Step Run the installer file and follow the installation wizard Step After the wizard completes open the CMD and type node v to verify the installation It will log the Node js version you installed e g v Step If everything is in order you can start a Node js server by following these steps You can also get the help of tools like Amplication to build high quality Node js applications without spending time on repetitive tasks Click this link to learn more about the features of Amplication FAQs Q What is the difference between Node js and Angular AngularJS Angular is a JavaScript based frontend development framework and AngularJs is the predecessor of Angular On the other hand Node js is a server side runtime environment that allows developers to run JavaScript code on the server side So Angular AngularJS is used to build client side applications while Node js is for server side development Q Why is Node js popular Node js is one of the most popular web technologies among developers The use of JavaScript for server side development handling high concurrency support for building highly scalable and efficient applications and non blocking I O are some of the key reasons behind the popularity of Node js Q Is Node js a programming language No Node js is not a programming language It is a runtime environment allowing developers to run JavaScript code outside the web browser Q Is Node js a framework No Node js is not a framework It is a runtime environment that provides an environment to run JavaScript code Node js is often mistaken as a framework since it includes several core libraries and APIs to help developers build web applications ConclusionNode js has become one of the most popular web technologies due to its excellent features like non blocking I O event driven nature scalability cross platform support and performance It also has one of the largest developer communities and a wide range of third party libraries to speed up development However Node js is not a silver bullet and there are some limitations you need to understand For example Node js is unsuitable for CPU intensive tasks and requires knowledge of asynchronous programming So developers must identify their requirements before choosing Node js as their runtime environment I hope this article provided a complete overview of Node js how it works its features and uses cases to help you decide when you should and should not use Node js Node js and AmplicationAmplication can automatically generate fully functional services based on TypeScript and Node js to speed up your development process Furthermore Amplication can include technologies like NestJS Prisma PostgreSQL MySQL MongoDB Passport Jest and Docker in the generated services Hence you can automatically create database connections authentication and authorization features unit tests and ORMs for your Node js service You can find the getting
