Seven RESTful Routes You Should Know!

I have been followed the course to develop several app projects. They all follow the RESTful route pattern. Today, I learned many key points about RESTful and would like to share my study note here.

What Is REST?

REST stands for representational state transfer. I don't know what does this mean, but it is not important right now. You just need to know that REST is just a pattern for defining our routes.

What's The Point Of REST?

The important things for us is to define what REST is.

REST is a way of mapping HTTP routes and CRUD functionality together. By the way CRUD stands for Create, Read, Update, and Destroy.

The point of REST is that we don't do whatever we want. Instead, we follow a pattern. It is also more reliable so that if we are interacting with a restful API, it follows a particular pattern.

Seven RESTful Routes

The course lists the seven route table. It just acts as a pattern that we can fill in the blanks when we develop our own App.

1. Index Route

The URL is "/dogs", and you can change the "/XX" depends on your App. The purpose is to list all the relevant data, in this case, all dogs.

2. New & Create Routes

New and Create routes are linked to each other. Both of them are for creating new data.

The HTTP verb of Create is "Post". The post is where we go to post form data to create a new data and then redirect to somewhere.

3. Show Route

The point of Show route is to show detail information about one particular data.

4. Edit & Update Routes

Edit and Update routes are linked to each other, too. They correspond to one another.

Edit is going to show us the form. Update is where the form submits.

Moreover, Update's HTTP verb is "Put" request. The process inside Update is that we need to find the old data first and then update it with new data. The purpose of "Put" request is to update something rather than posting new things.

5. Destroy

Destroy is a single route. It's going to delete request to the "/dogs/:id". The point is that Destroy leads to a particular thing and then redirect somewhere.

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. Step Three: Write styles in CSS file I simple give body an orange background color and set text color to be grey. Step Four: Link to CSS file in the EJS file I just add <link> tag to link the "app.css" file on the top of the h1 tag in each ejs template. As the result, when I run the app and...

Intro to Backend: Is Browser The Only Place To Send HTTP Request?

Today, I begin to learn the second part of web develop course: backend. Frontend is the stuff that we can see and interactive with, such as HTML, CSS, and JS. We can type our code, style our page, or write some function to make interaction. However, backend is everything else. For example, we type Target web address in the Internet Browser. As we hit "enter", there are a few steps to go through: 1. The HTTP request is sent to a particular server's IP address. 2. The server figures out what to send us 3. It sends a HTTP response back to us Those process we are hard to see, and it happens in less than one second. The instructor said that the browser is not the only place to send the HTTP request, and there are so many choices out there. In this learning course, we are going to use Postman App . Postman allows us to make HTTP requests and viewer responses. It is really for developers to understand how things are working or debug something. In the P...

Intermediate CSS: Three Steps To Create A Photo Gallery

I have seen many image blogs these years. People love to post their photos online to express life and feeling. Image is powerful because it could bring a visual story to audience. People can see what you see, and may be feel the same way as you feel, too. If we want to build our own photo gallery, what should we do? Luckily, the boot-camp instructor just showed me how to use HTML and CSS to create a simple photo gallery. I would love to share my study note here. (p.s. all the image links are provided by Udemy course instructor) Step One: Add Image Links on HTMLPage The instructor provides all the image links. All we need to do is add those links inside the <img> tag. Without CSS, the page will looks like this: they are not organized, and sizes are different, too. Step Two: Set Image Property Values We set the width of each photo the same value which is 30%, so there will be three images per line. The percentage value can help...
