If you are a web developer, you know that AngularJS is one of the most popular and powerful JavaScript frameworks out there. It can help you build dynamic and responsive web applications quickly and efficiently. However, as with any technology, there are tips and tricks that can help you get the most out of it. In this article, we will provide you with some of the best AngularJS tips and tricks to help you develop better web applications.
1. Introduction
AngularJS is a JavaScript framework developed by Google to help web developers build dynamic and responsive web applications. It is a powerful tool that has many features that can help you develop better web applications. However, as with any technology, there are tips and tricks that can help you get the most out of it.
2. Use ng-cloak Directive to Avoid Flickering
If you are using AngularJS to build your web application, you may have noticed a flickering effect when the page loads. This is caused by the time it takes AngularJS to load and render the page. To avoid this flickering effect, you can use the ng-cloak directive. This directive tells AngularJS to hide the content until it is fully loaded and rendered.
3. Use ng-repeat Instead of ng-if to Save Performance
When you are working with AngularJS, you may need to show or hide certain elements depending on the data. You can do this using the ng-if directive. However, if you have a large dataset, this can slow down your application. To save performance, you should use the ng-repeat directive instead. This directive will loop through the data and show or hide the elements based on the data.
4. Use AngularJS Modules to Organize Your Code
One of the key features of AngularJS is the ability to organize your code using modules. Modules are a way to group related components of your application together. You can create modules for your controllers, services, directives, and filters. This makes it easier to manage your code and keep it organized.
5. Use AngularJS Filters to Format Data
AngularJS filters are a powerful tool that can help you format data. Filters can be used to format dates, currency, and text. For example, you can use the date filter to format a date in a specific format, or the currency filter to format a number as a currency.
It’s useful to realize that you can restructure Angular’s default registries. The default indexes you’re given will rely upon the sort of software you’re composing. For instance, you’re given indexes for controllers, sees, services, templates, and models. This structure works fine for smaller projects where you can undoubtedly find documents for a specific module. If you’re working with 10 documents for an application, you can utilize this default structure with little hassle.
However, when the application grows to medium or enormous size, you could be working with several documents. Attempting to discover a record for a specific module can be repetitive, making it increasingly successful in revising your directory structure to aggregate your venture by logical segments. For example, the accompanying directory structure could work:
application/
app.js
dashboard/
frontpage.html
frontpagecontroller.js
frontpageservice.js
request/
order.html
ordercontroller.js
orderservice.js
In this model, two logical components (first page and request) are given their very own registries. If one of these modules breaks, you know promptly where to discover it.
In an MVC architecture, each module is separated into either the model, view, or controller. The view is the place your presentation logic is coded. The presentation is anything to do with the Document Object Model. If you have to change an incentive in any HTML component, you should utilize the presentation layer to do it.
When you perform presentation execution in the controller instead of the view, you break the partition of layers. When you or another developer returns to keep up the code, you can miss the code in your controller that shouldn’t be there. This can prompt bugs.
Remember that MVC architecture is entirely different than old fashioned, straight web dialects. When you become accustomed to it, however, you’ll see it substantially more sensible when you have to manage large scale applications.
When we talk about web development, many developers seek tips and tricks to improve the website.
However, web development, particularly in PHP, is pretty easy for newbies.
All they need to know are the vital PHP tips and tricks that can help them in developing a PHP website and optimizing it.
In this, you will see the tips on:
1. Ternary Operators
2. PHP Exception Handler
3. array_key_exists() vs in_array()
4. unserialize() vs json_decode()
