Bootstrap 4: Navs in Flex

I mentioned that flex box allows items to move inside a container. In the last post, I use buttons as an example to show how do those buttons move in the flex box. Today, I learned navs can also move in a flex box.

I would love to share my study note here.

Firstly, I copy the Bootstrap 4 starter template on the editor, and also put the base nav code in the body.

In order to show how navs move in the flex, I add a border outside the navs. The result shows a base nav bar inside a box.

Move in Row

Then, I want to add some space between each nav items, so I set "justify-content-around" value in the <ul>.

The result:

You can also move the items to the right (justify-content-end) or to the center (justify-content-center).

Move Vertically

If I want to show my nav bar vertically, I can just simple set "flex-column" value.

The result:

Responsive Nav

If I want the nav bar change from the horizontal to vertical as the page changes to a smaller size, I can add "flex-sm-row align-items-center" next to the "flex-column" value.

The result:

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 ...

Authentication Project: Secret Page App Part One (Set up & Create User Model)

So far we only write the RESTful routes to send request and redirect to the related page, but we haven't do anything about authentication. If we can sign up, login, and log out, it will make our app more meaningful. Therefore, the course shows us how to create a secret page app, which will allow us to sign up, login to a secret page, and logout. Since it requires so many pieces, I will divided this project into three parts: set up & create user model, sign up, and login/logout. In this post, I am going to show all the set up process. Set Up Step One: Install packages The first thing we are going to do to create a folder "Auth", and inside of "Auth", we need to create another folder "AuthDemo". Then we cd (change directory) to "AuthDemo". Now we can set up the actual application structure by installing a few packages: passport, passport-local, passport-local-mongoose, mongoose, express, ejs, body-parser, and express-session....
