Angular is a Google open-source JavaScript framework that is widely used to create frontend apps, truly native angular applications, and just SPAs.

Because it was created to overcome the constraints of previous JavaScript frameworks, Angular is one of the most powerful frameworks for developing online applications that are geared for speed and performance.

Angular is now used by over 40% of Melbourne web developers for web apps. We felt it would be a good idea to share a few Angular best practises with you because of its broad popularity.

Following Angular Coding Styles Consistently

Gaining efficiency in code is one of the most critical factors to get correct for any frontend JavaScript framework. Your app’s effectiveness is mostly determined by the quality and health of your code. You should always endeavour to follow Angular code standards by following particular Angular coding styles as a developer. When working with complicated code structures, developers frequently become overwhelmed and have difficulty correcting faults and discovering urgent concerns.

Here are some of the essential coding standards for sticking to the Angular Style Guide in your Angular project.

  • Make sure the code does not exceed the file limit of 400 lines.
  • Make sure each function’s code does not exceed 75 lines.
  • Use the keyword ‘const’ to declare variables with constant values.
  • In lower camel cases, the names of properties and methods should be utilised.
  • Between imports and modules, always leave an empty line.
  • Don’t start the interface names with an uppercase ‘l,’ as other programming languages do.

Use Dependency Injection

The module in AngularJs is dependent on other components such as values, services, conf, and so on. Angular dependency injection allows us to provide an unattached component an instance of the dependant component. You may use the [] notation to list your dependencies alongside the functions and inject them by their name. Angular has a dependency injector that keeps track of all components such as values and services and may use dependency injection to return instances of required components.

Use Scope Properly

For Angular apps the scope may be utilised as a data container. When utilising the scope as a container, avoid storing DOM elements in the scope because this can cause massive memory leaks. Only use scope when passing data between HTML (view) and JavaScript (controller).

The Single Responsibility Principle

Within a single file, you should not create more than one component, service, or directive. Each file should be in charge of only one function. We keep our files tidy, readable, and maintained by doing so.

Avoid Memory Leakage in Angular Observables

In any programming language, library, or framework, memory leaking is a severe issue. Memory leaks are a source of concern, and if you’re not careful while designing an app, they may happen quickly. Memory leakage has the potential to create the worst-case situation while developing an app.

Using Service Workers to Create a Responsive App

Angular is known for making user interactions simple. It accomplishes this by transforming typical web apps into single-page apps, adding responsiveness, and building interactive web apps.

Users may collaborate with online apps more easily thanks to the service workers. Users can swiftly engage with web apps thanks to service workers. By integrating native capabilities, we may turn our single-page application into a progressive web app (PWA). Any version of the Angular framework above five supports service workers.

Service workers act as network intermediaries. They improve the user experience by letting users to interact with native web application functionalities without having to wait for internet connectivity.

Script Should Be Kept to The Bottom of The Page

External scripts, such as controllers and modules, should be referenced at the bottom of the page. Putting scripts and modules near the bottom of the page has the advantage of not making the page wait for the script to load.


Angular is a web application framework that is dependable, robust, and comprehensive. It is more efficient to construct an app using Angular since it does not require third-party libraries. These techniques can help you create a high-end application by ensuring a faultless development process. We believe that this blog will assist you in quickly developing a complicated and impressive web application.
