#nodejs express

今日既NodeJs 筆記是用來記錄一個十分簡單的功能 就是 Get Query String或是取後 GET 的 paramater.

解決方法

if(req.params['location'] == undefined){ console.log("No parameter named 'location'"); }else{ console.log(locaton); }

Hope you find it useful

NodeJS – ejs reference to root path – HTML reference to root Path for the JS/CSS/Image File

HTML reference to root Path for the JS/CSS/Image File 今天在學習NodeJS with Express 又遇到問題了 就是不知道怎樣可以reference 返D Javascript /CSS 檔案到 Root Path/ Root Directory 之前用 Codeigniter 可以使用 base_url() ASP.Net MVC 可以用 <pre> @Styles.Render(“~/Content/css”) @Scripts.Render(“~/bundles/jquery”) </pre>

當我使用路徑”css/bootstrap.min.css“.. 在其他的path 便出現問題 <pre> <link rel=”apple-touch-icon” href=”apple-touch-icon.png”>

I hope you have a terminal handy

This is it, get ready, we are making this beast from scratch. Who knows where it will take us, but I have a few tools you need to acquire: Nodejs, npm(should come bundled with node), a terminal, some sort of editor, and an open mind.

Let’s dig in!

Make a directory, anywhere and name it something nice, mine is called foss_blog, but you can name yours super_fun_node_time_ultra. If you aren’t already in a terminal at this point pop one open and cd into your shiny new directory. Once you get there type the command npm init, you will be given a series of questions that you may answer how you like, including giving a license. Don’t worry, these are not final answers. The output of this command is a file called package.json, which you can edit at any time.

Here is what mine looks like

{ "name": "foss_blog", "version": "0.0.1", "description": "A blog engine built for HFOSS", "main": "server.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "keywords": [ "blog" ], "author": "Peter Gyory", "license": "MIT", }

You now have the beginnings of a Node project using npm! If you haven’t used npm before, it is quite similar to pip or gem, except it’s for Node. Many of the commands are the same, and the npm website has more libraries available than you could dream of.

Now before we wrap this up and I init the git repo, let’s take a second and install something I know we will need. Type in your terminal npm install --save express. This will install the express framework that will be the basis for our blog. If you look again at the package.json file you will notice that there is this little addition.

"dependencies": { "express": "^4.13.3" }

This wonderful file also keeps track of all of the libraries you have installed, so all you need to do when you download the code is run npm install and you will have a fully set up environment.
