What Is Angular Ivy and Why Is It Awesome?

Build a Beautiful App + Login with Angular Material

Usability is a key aspect to consider when creating a web application, and that means designing a clean, easy-to-understand user interface. Leveraging common design languages can help make that goal a reality with their recognizable components that many users will understand right away. However, unlike desktop apps where the operating system provides a set of uniform widgets, there has historically been no common design language to lean on for web app developers. That was until...

Use Sass with React to Build Beautiful Apps

When you are developing web applications with React, you know that writing the JavaScript code is only half of the story. The other half is implementing the design using style sheets.

How to Customize Your Angular Build With Webpack

If you’re a frontend dev in the world today you’ve probably heard of (and possibly even used) webpack.

Use Vue and GraphQL to Build a Secure App

When you develop a new web application, you most likely split the application into two parts. The server-side provides access control and data persistence, while the client-side is mostly presentational. The two parts have to communicate, and your first idea may be to implement a REST API. However, a number of flaws have been identified with the RESTful pattern, mostly related to the flexibility and speed of the request-response pattern. At Facebook, these problems were...

Angular Authentication with JWT

User registration and authentication are one of the features that almost no web application can do without. Authentication usually consists of a user entering using a user name and a password and then being granted access to various resources or services. Authentication, by its very nature, relies on keeping the state of the user. This seems to contradict a fundamental property of HTTP, which is a stateless protocol. JSON Web Tokens (JWTs) provide one way...
