Introduction
AngularJS is an open-source JavaScript framework for building front-end applications released by Google. It is considered one of the most widely used and popular JavaScript frameworks for developing dynamic desktop and mobile applications. The Angular framework is managed and maintained by the engineers working at Google. It gained immediate support because now static HTML pages could be made interactive and customized according to the requirements.
Currently, there are more than 40% of front-end developers using Angular because of its wide popularity. It is constructive activity to highlight a few practices that we are appreciative of.
In this blog, we’re going to talk about the Angular best practices that a web developer should keep in mind while developing a project and code easier to manage and debug. So, without any further delay, let’s get started!
Top 7 Angular Best Practices to Follow in 2021
- Isolate API hacks
As we all know that all APIs are not bulletproof. Sometimes it is required to add some logic in the code to make up for bugs in the APIs. Rather than having hacks in components where they are needed, it is a good practice to isolate them in one place — like using a service from the component. You must be wondering, why is it necessary? If so, then it helps to keep the hacks closer to the API which requires less coding and deals with the un-hacked code
It also allows you to create custom tags similar to TODO and tag the fixes so that it becomes easier for developers to search and find the required API.
- Use Angular CLI
One of the powerful and most widely used tools available for developing applications in Angular CLI. It makes it easy to build an app and follows all the best practices. It is a command-line interface tool that is used to develop, maintain, initialize, and test and debug Angular apps. So instead of creating files manually, make sure you’re using Angular CLI to generate new modules, services, components, and pipes.
| # Install Angular CLI
npm install -g @angular/cli
# Check Angular CLI version
ng version |
- Subscribe in the template
Rather than subscribing to observables from components, make sure to subscribe to the observables from the templates because async pipes unsubscribe themselves automatically to make the code simple by avoiding the need to manually manage subscriptions. It helps to reduce the risk of forgetting to unsubscribe a subscription in the component and detect unsubscribe observables.
It also stops components from introducing bugs where the data gets mutated outside the subscription.
Before:
| // // template
<p>{{ textToDisplay }}</p>
// component
iAmAnObservable .pipe( map(value => value.item), takeUntil(this._destroyed$) |
