Angular JS 命名约定($、camelCase 和 PascalCase) [英] Angular JS naming conventions ($, camelCase and PascalCase)

问题描述

AngularJS 中使用 $ 作为提供者前缀的约定是什么?我应该在自己的代码中为所有自定义服务添加前缀吗?

What is the convention in AngularJS for prefixing providers with $? Should I prefix all custom services in my own code?

看起来所有带有 angular 的东西都有前缀服务，例如$http.然而，在大多数文章中，控制器没有以 $ 为前缀.此外，所有 Angular 代码都带有以 camelCase 命名的服务，但是我也在许多在线博客中看到了 PascalCase.哪个是约定俗成的?

Looks like all things that come with angular have prefixed services, e.g. $http. Controllers, however, are not prefixed with $ in most articles. Also, all angular code comes with services named in camelCase, however I've also seen PascalCase in many blogs online. Which one is the convention?

推荐答案

文档声明了内部服务的这个约定，但也声明您不应该为自己的服务这样做以减少命名冲突.

The docs state this convention for internal services, but also state you should not do it for your own services to reduce naming collisions.

另外，关于camelCase，文档说使用camelCase.

Also, regarding camelCase, the docs say to use camelCase.

Angular 使用带破折号的名称作为属性名称，使用驼峰命名法作为对应的指令名称

Angular uses name-with-dashes for attribute names and camelCase for the corresponding directive name
