angular variable naming conventions

The Rule of One is adapted from the Single Responsibility Principle in software engineering that essentially states that your app or program should be split up into different areas of concern with each area focused on one piece of program or system functionality. Adhering to the Rule of One means that your Angular app will be split into different feature modules that each implement the business logic for one feature. Following sample code shows how to apply namespacing for HTML files: Example of creating a custom view component, Creating custom view components for record editor, Powered by Atlassian Confluence and All service classes should end with the term Service. By following the style guide, you will ensure that your code stands the test of time! 121 0 obj

When using any big framework like Angularespecially on a developer team of substantial sizeit is imperative that you follow recommended best practices. Another important piece to the Angular style guide is the Rule of One.

At a high level, each of these modules might look like the following: By following the Rule of One, you will ensure that your app is as simple as possible. endobj %PDF-1.5 endobj endobj Namespacing helps you to organize the objects of your Digital Service application so that they can beidentified uniquely when shared and collisions with other objects or variables in the global namespace are avoided. 116 0 obj SONAR, SONARSOURCE, SONARLINT, SONARQUBE and SONARCLOUD are trademarks of SonarSource S.A.

In this guide, we will touch on some of the key principles kept within the Angular coding style guide and look at some code samples in order to cement our knowledge. Ex: By following these naming conventions, you will ensure that your app is more easily maintainable. All content is copyright protected. Setup is effortless and analysis is automatic for most languages, Fast, accurate analysis; enterprise scalability. For more naming conventions, check out the naming portion of the official Angular style guide. This documentation supports the 20.08 version of BMC Helix Platform. 120 0 obj Developers who onboard onto your project will have a much easier time getting up to speed! %# , #&')*)-0-(0%()( C Privacy Policy, Detect issues in your GitHub, Azure DevOps Services, Bitbucket Cloud, GitLab repositories. % << /Filter /FlateDecode /S 191 /Length 176 >> To ensure global uniqueness of angular object names in the shared JavaScript code of your application, you must ensure that you follow the following naming conventions: All angular object names in shared code (services, factories, providers, controllers, directives, constants, filters) must be prefixed with bundle ID and converted to camelCase (for example, comExampleTaskmanagerTmsServiceOne).Following sample code shows how to apply namespacing for angular objects: All HTML filenames in shared code (for example, view and directive templates) must be prefixed with the bundle ID. This means less mental complexity, and that is always a good thing when it comes to developing your app! For a deeper dive and to see how else the Angular style guide can benefit your app, you can check out the official Angular coding style guide. With the default regular expression ^[_$A-Za-z][$A-Za-z0-9]*$|^[_$A-Z][_$A-Z0-9]+$: 2008-2022 SonarSource S.A., Switzerland. 118 0 obj naming conventions standard timeout w"Et:YmwbEVQwqLk)c93kr9: endobj This will make your app much more maintainable in the long run. This is so that your custom selectors closely match the surrounding HTML but are also easily distinguishable due to the prefix. endobj << /Linearized 1 /L 190885 /H [ 1251 257 ] /O 120 /E 86169 /N 14 /T 189919 >> Following the official Angular style guide is a big step towards producing clean, maintainable code that is written the "Angular" way. endstream JFIF C This rule checks that all variable, Angular is a big, opinionated JavaScript framework that is heavily used by enterprises and organizations that are looking to write JavaScript that scales. By following the Angular style guide closely, you can ensure that new Angular developers can easily get up to speed on your app because they will not have to learn a bunch of custom domain knowledge. stream Sharing some naming conventions is a key point to make it possible for a team to efficiently collaborate. 119 0 obj Ex: Selectors for your components should always be dash-delimited, like files, and contain the appropriate app prefix. endstream For example, let's say your Angular app is concerned with showing shipping lanes to users on a map.
