Angular JWT authentication (#7 of 100 projects)

This project took me really long to finish. I spent so much time trying to write a comprehensive blog post on explaining the project. But I realized my goal is to create 100 projects in using Angular framework, not to produce 100 how-to tutorials on Angular.

So this post is rather an update on what I’ve done than a guide post.

In this project, I’ve created a website with a dashboard which is password protected. JWT authentication is implemented using a backend created in Django and hosted in my c9.io instance.

In this project, I’ve created the following:

  • A password protected dashboard component
  • An authentication service to post request to backend API
  • A login component
  • An http interceptor to include JWT token in the http request

Angular dharma page #5

DharmaPage

This is the number 5 of my 100 angular projects. This project is based on the previous one Angular dhamma player #4.

This project has two components; the main page and audio track player page. On the home page, four images of famous Burmese Monks are shown in card style. When the user clicked on a card, they are brought to a player with the dhamma talks of the selected monk.

Basically, I am trying to learn how to use the Angular router for navigation between different components in a single page application.

Everything went well, except for one thing. I have been spending way too much time messing around with CSS and colors instead of focusing on functionality.

So, from now on I will spend less time on design aspect and more on functional aspects for future projects.

Angular dhamma player #4

This is the #4 in my attempt at building 100 projects with Angular.

In this project, I decided to build a simple audio player with a playlist attached. I learned the following concepts while implementing it.

  • *ngFor to display list
  • master/display components
  • event handling with (onclick)

HTML5 audio element is used for playing the mp3 files in the list. This audio player component is a very simple component and I intend to use it in the bigger project later.

Check out both live project and source code for more details.

Angular random quote #3

This is the third project of my ongoing challenge, 100 angular projects.

In this project, I created a web page which fetches a random quote from an API endpoint and displays it on the page.

I have learned a few new concepts while creating this simple web application, such as

  • using services to separate fetching data from components
  • using observable and Angular HttpClient for fetching data asynchronously and providing a way for the data to be consumed from a component
  • calling child component’s function from parent component using @ViewChild

Hello angular with style #2

This is the second post from the series of 100 angular projects I am doing. You can check out the first post here.

Based on the previous hello world project, I decided to have a little fun by adding CSS framework Bulma which is the new cool kid on the block. Watch out Bootstrap!

First I added the Bulma in the project using npm install:

npm install --save bulma

Second I imported the Bulma in src\styles.css:

 @import "~bulma/css/bulma.css"

Now Bulma styles are available globally. Afterward, I created two components for header and footer.

ng generate component components/header
ng g component components/footer  ## g is shorthand for generate

This will create header and footer components in src/app/components folder.

Edit the header.component.html, footer.component.html, and app.component.html for the Bulma hero layout look.

Let’s create a header with only a brand logo.

And create a footer with license information.

Finally, add those components into the main app.component.html.

That’s it. We are done.

This time, I used Netlify for deployment. It is very easy and it works.
