Res.send('HTTP method doesn't have any effect on this route!') To test this request, open up your terminal and use cURL to execute the following request в€’Д¬url -X POST ' A special method, all, is provided by Express to handle all types of http methods at a particular route using the same function.

Res.send('You just called the post method at '/hello'! ') We can also have multiple different methods at the same route. If we run our application and go to localhost:3000/hello, the server receives a get request at route '/hello', our Express app executes the callback function attached to this route and sends 'Hello World!' as the response. Handler is a callback function that executes when a matching request type is found on the relevant route. Path is the route at which the request will run. An alternate method also exists, which executes independent of the request type. This METHOD can be applied to any one of the HTTP verbs вЂ“ get, set, put, delete. The following function is used to define routes in an Express application в€’ app.method(path, handler) app.Web frameworks provide resources such as HTML pages, scripts, images, etc. We do this by using the ExpressвЂ™s listen method. We need to create a server that browsers can connect to. Next, we use express in server.js by requiring it.

ItвЂ™s important to know these dependencies because npm can retrieve dependencies with another npm install command when you need it later. The -save flag saves express as a dependency in package.json. Run npm install express -save command in your command line. ( npm is installed with Node, which is why you use commands like npm init and npm install). We can do this by running the npm install command. Using ExpressДЇirst, we have to install Express. The next step is to learn to use Express. Now, run node server.js in your command line and you should see this: This lets us know whether Node is running properly. Next, put this a console.log statement into server.js. LetвЂ™s create a file called server.js to run node with. The simplest way to use node is to run the node command, and specify a path to a file. Running Node for the first time in your life IвЂ™ll talk about the ones you need to know as we go along. Just hit enter through everything that appears. Npm init creates a package.json file which helps you manage dependencies (which we will install as we go through the tutorial). After youвЂ™ve created the folder, navigate into it with the Terminal and run npm init. Start by creating a folder for this project. If you donвЂ™t, you can install Node either by downloading the installer from NodeвЂ™s website or downloading it through package managers like Homebrew (Mac) and Chocolatey (Windows). You should get a version number if you have Node installed.

To check if you have Node installed, open up your Command Line and run the following code: $ node -v If youвЂ™re afraid, use this article to get over your fear. You are not afraid of typing commands into a Command Line.YouвЂ™ll need two things to get started with this tutorial:

This article is LONG! Remember to grab the source code by leaving your name and email address in this form. HereвЂ™s what it looks like:ДЇree free to check out the demo before continuing with this tutorial. LetвЂ™s build a simple application that lets you track a list of quotes from Star Wars Characters. WeвЂ™ll build a simple application together If we put CRUD, Express and MongoDB together into a single diagram, this is what it would look like:Дoes CRUD, Express and MongoDB makes more sense to you now? POST, GET, PUT, and DELETE requests let us construct Rest APIs. It is a set of operations we get servers to execute ( POST, GET, PUT and DELETE requests respectively).

This is the place where you store information for your websites (or applications).Д¬RUD is an acronym for Create, Read, Update and Delete. In case you were wondering, Node allows you to use JavaScript as your server-side language. It simplifies the server creation process that is already available in Node. LetвЂ™s quickly introduce what they are before we diving into the tutorial.Д®xpress is a framework for building web applications on top of Node.js. CRUD, Express and MongoDBД¬RUD, Express and MongoDB are big words for a person who has never touched any server-side programming in their life. I want to write a comprehensive tutorial so you wonвЂ™t have to go through the same headache I went through.
