This article is perfect for you if you are a beginner looking for tips and tricks on using Angular on your website. With these five common mistakes avoided, you can get the most out of your time when building your Angular application.
What is Angular?
Five common mistakes to avoid when using Angular are:
- Making assumptions about the state of the applicationAngular is a fantastic tool for creating complex applications, but it’s not a silver bullet. You need to be aware of the assumptions you’re making about the state of your application and be prepared to handle any errors that crop up. Assuming your data is always available: When working with Angular, never assume that your data is always available. If you need to access data from a remote source, or if your data changes frequently, you’ll need to make sure that you have a way to update your application accordingly. Assuming that everything will work as expected: Just because something works, in theory, doesn’t mean it will work in practice. Before you start coding, make sure that all your assumptions about how the application will work are correct.Ignoring errors: If something goes wrong while you’re working with Angular, don’t panic. Instead, try to find out what went wrong and correct the error as quickly as possible.
- Not testing your code thoroughlyAngular is an excellent tool for creating Single Page Applications, and angular is easy to use in 2023, but it’s not perfect. Make sure to test your code thoroughly before releasing it to the public. Not testing your unit tests enough – Angular is a testing-intensive framework, so you should ensure that all of your code is appropriately tested before pushing it to the public. Failing to isolate your dependencies properly – To avoid problems with circular dependencies, make sure that all dependencies are correctly isolated. This means that a different module or package implements each dependency.Ignoring non-angular dependencies – Angular can be used without any dependencies, but this doesn’t mean you won’t run into problems. Make sure to include tests for any non-angular libraries that you use.
Not following best practices – Angular follows many of the same best practices as other modern web frameworks, but there are a few things you should avoid if possible. For example, don’t use global variables or functions in your code.
- Using hard-coded URLsWhen using Angular, it’s essential to avoid making common mistakes. One of the most common mistakes is using hard-coded URLs.Hard-coded URLs are URLs that are stored in the source code of your application. This means that anyone who accesses your application directly can see these URLs. This can be dangerous if someone accesses your application without authorization.
Instead, you should use relative URLs when building your applications with Angular. Relative URLs refer to files and folders within your project rather than specific absolute URLs. This makes it difficult for outsiders to access your source code, but it allows you to refer to files and folders within your project using standard references such as “./folder/file.js”.
- Using incorrect types in classes and methods
- Using strings instead of objects
- Creating methods without a return type
- Pasting code from other sources into your Angular application
- Using ng-repeat without proper selector syntax
- Using the wrong type of scope in NgModule
- Angular is not using routingOne common mistake that beginners make when using Angular is not using routing. Routing is the process of mapping resources (pages, files, parameters) to URLs. Without proper routing, users can’t access the resources that they need.Angular provides several built-in routes to help you get started. You can also use third-party routing libraries like AngularRoute to extend Angular’s capabilities.
If you’re not using routing, your users will have trouble finding the needed resources. Make sure to use Angular routing to help your users find the needed resources.
