Creative ways for a Clean and Performant Angular application
Published On : February 12, 2022 Category(s) : Angular, trending
Angular (Learn Angular Application Development) is a TypeScript-based framework widely used to make web and mobile applications efficiently. It is a free and open-source framework and has been enhanced to overcome the drawbacks of other frameworks. The interactive tools and highly functional features allow the user to create high-speed and performance web applications. Angular provides you with the freedom to not rely on third-party libraries while developing your app. However, if you disregard the coding practices in Angular, you are likely to face bugs and performance issues. Your coding practices directly resonate with the output, and hence having an organized checklist for the same is essential. Several Angular development companies and Angular developers have incorporated these practices into their code to give quality outputs. This blog will talk about a few of them to enhance your coding rituals and reduce the complexity a little. (Contact us for Angular Development Services)
Use Angular CLI
Angular Command Line Interface (Angular CLI) is a tool for helping Angular web development companies and Angular development services with initializing, developing, and maintaining applications. This also allows developers to debug and test the apps. All the Angular versions support Angular CLI.
A few essential functions that are included in the tool are
- ng new – To create an application that is new and fully functional.
- ng generate – Generate components, routes, services, and pipes with the help of an easy-to-use command-line tool.
- ng serve – To test and find errors in your app locally during the developing stages.
- ng test – For running unit tests and end-to-end tests
- ng lint – To essentially check the quality and make your code shine
Angular CLI can be a great add-on to better understand the folder structure and app flow. It saves a considerable amount of time for developers too.
Use trackBy along with ngFor
When the built-in Angular directive ngFor is used to loop an array in the template, the manipulation of DOM can get crafty. Angular essentially does not keep any record of the data being iterated, and to implement the directive, all the DOM elements are exploited. This can be very expensive when dealing with a massive collection of data. And so, even hiring Angular developers and professional services can be a good option if you’re facing such an issue.
To avoid this altogether, the trackBy function gives a unique identifier to each collection item, hugely impacting the amount of time and money the DOM rendering process will take.
Module Organization and Lazy Loading | Angular Application
Lazy loading is yet another one of the best practices in angular. It aids performance and productivity with its built-in features. It allows JavaScript to load components on demand, fundamentally divides the entire application into small bundles, and only loads the ones required to alter its speed. Along with that, there are multiple modules used in Angular apps widely:
- Multi Modules
- Routing Modules
- Shared Modules
- Lazy Load Modules
Always Document
Documenting the code as much as possible is always a good practice. It helps external developers involved in the project to understand the logic behind every line of code and increase its readability score. Every method, variable, and parameter should be explained in detail using multi-line comments.
Use Index.ts
Index.ts function allows developers to keep track of all things and bundle them together, reducing the bother about the source file name. Even though it is not mandatory, it is good to keep files organized in one place. This, in turn, helps reduce the import statement’s size and enhances the application’s performance.
Follow consistent Angular coding styles.
Standard coding practices are often overlooked by developers. That is when the external Angular development services and companies come into the picture. Professional developers implement set code styles to increase their projects’ understandability, readability, simplicity, and adaptability.
- Every single file should have code lines limited to 400.
- Every single function should be defined and have the code lines within 75.
- Use custom prefixes and prefixes for various slider components.
- Utilize const if the values are constant and intact throughout the file.
- Use meaningful names for functions, and place them in lower case.
- Import third-party dependencies/modules before application modules. And leave a line between these custom imports.
Conclusion
Angular is a compelling framework with a lot of functionality. The vast amount of features makes Angular optimal for large enterprise solutions. And while it is a practical framework, it’s tough to master. You may find it overwhelming at first with all the options and whatnot since you’re a new player.
