API's Study Notes: How To Make API Request With Node?

The course shows us we can make API's requests with Node.

The first thing we need to do is to create the "APIs" directory and touch "request.js" file inside that folder.

Then, we need to npm install request package in the APIs directory.

Once we have done those basic steps, we can start to require the "request" and make a request from a JavaScript file.

In the request, we need to have the "url", so the server knows where it should request the API. Next, we need to have a function.

request("url", function(error, response, body)

In the function, there are three things we pass in: error, response, and body.

Error: it will hold any potential error that we get such as internet disconnect, 404, and etc. It is important to check for an error.
Response: it will be the incoming message that we receive
Body: it is the actual response body that came back like HTML code

For example, in the "request.js" file, I make a fake URL in the request, and I write an if statement to check error.

If there is an error, it will print out the error. Else if the response status code is equal to 200, which means the request was received is fine to process, we can print out the body.

Since this URL is a fake one, the request won't be processed correctly. Therefore, the server print out the error message.

Now, I put my personal WordPress blog URL in the request, and run the server. Since my URL is correct, so the server can receive the response and process it. As a result, we can see it print out the Wordpress blog HTML code.

Intermediate Express.js: How To Add Styles & Partials in EJS File?

So far, we only have simple HTML tags and ejs tags in each ejs file. Every template page has no style at all. And the basic HTML header and footer are also missing. Today, I learned how to add styles and partials in ejs file. Link Style Step One: Touch a Separate CSS file I create a new directory "Style" under the "EJSDemo" directory, then I add a new CSS file "app.css" inside "Style" folder. Step Two: Add app.use(express.static()) in the app.js I add app.use(express.static("style")) in the "app.js". This will tell Express.js to serve the content of "Style" directory.

Intermediate Express.Js: Write Conditions and Loops In The EJS (study note)

We continue to use the app.js which we have build to be the study example. In the last post, we only add a simple EJS tag <%= thingVar %> inside h1 tag. This will match the "thing" to any "thing" request from the user. If Statement Today, the course shows us to write a simple if statement in the EJS file. I learn to apply it to my own app. In the if statement, if users send"/wantto/workout" request, the page will show a new content "Good Idea!". We wrote the if statement in the "diet.ejs" file, and we add "<% %>" tags around the code. We have to wrap every line of JavaScript anytime JavaScript starts and ends. Moreover, you may see there are two types of ejs tags here: <%= %> The one with equal sign. According to the course, when we add equal sign, the value that is returned inside of the tag will be rendered to the HTML page. it will be added to the HTML. For example, if we write ...

My Story: A Mommy Start To Learn Code From Zero

From Google Image I am not a programmer, and I thought I would never become one. Everytime I see someone is coding, I think he or she must be very talent. For me, coding is a very difficult subject to learn. Not only the language has so many rules, but also the logical reasoning behind the language is complex. In my graduated school, I knew many friends who didn't have any coding background, but they are doing programmer or developer jobs now. Some of them went to school to study coding, and some of them learned to code by themselves. Their stories are so impressive. I wasn't ready to learn code until I finished my first Chinese book "留学，我的青春呀!" recently. I always want to be a writer and write my own book. I started writing blog three years ago, and I updated my post two to three times every week. As I enjoyed writing , I started to get some followers, likes, and good comments on my blog. Then, I decided to plan my first book. My First...
