Constant

Modules can individually provide their own Constant

Initialize code skeleton

1. Cli command

$ vona :init:constant demo-student

2. Menu command

TIP

Context Menu - [Module Path]: Vona Init/Constant

Define Constant

Taking the module demo-student as an example, define the Constant of the module:

src/module/demo-student/src/config/constants.ts

export const constants = {
+ gender: {
+   male: 1,
+   female: 2,
+ },
} as const;

Just define the required constants directly, and the system will automatically extract the type information of constants

Use Constant

The Constant of the module can be obtained through the Scope instance

class ControllerStudent {
  async test() {
+   console.log(this.scope.constant.gender.male);
+   console.log(this.scope.constant.gender.female);
  }
}

Use Constant cross-module

class ControllerOther {
  async test() {
+   console.log(this.$scope.demoStudent.constant.gender.male);
+   console.log(this.$scope.demoStudent.constant.gender.female);
  }
}
