Static

In VonaJS, each module can provide static resources, accessible via a URL.

Initializing the Code Skeleton

1. Cli Command

$ vona :init:static demo-student

2. Menu Command

TIP

Context menu - [Module Path]: Vona Init/Assets Static

3. Adding Static Resources

Executing the above command will automatically create the directory: assets/static

Add static resources according to business needs, such as adding two images:

src/module/demo-student/assets/static/img/vona.png
src/module/demo-student/assets/static/img/vona.svg

4. URL

Static resources can be accessed via the following URL:

http://localhost:7102/api/static/demo/student/img/vona.png
http://localhost:7102/api/static/demo/student/img/vona.svg

You can use meta.static to get the URL of a static resource in a typed way.

Create meta.static

For example, create meta.static in the module demo-student.

1. Cli Command

$ vona :create:bean meta static --module=demo-student

2. Menu Command

TIP

Context menu - [Module Path]: Vona Meta/Static

meta.static Definition

export type TypeStaticGetPath = 'img/vona.png' | 'img/vona.svg';

@Meta()
export class MetaStatic extends BeanStaticBase<TypeStaticGetPath> {}

• TypeStaticGetPath: Defines the type of the static resources

Get the static resource path

class ControllerStudent {
  test() {
    const path = this.scope.static.get('img/vona.png');
    assert.equal(path, '/api/static/demo/student/img/vona.png');
  }
}

• static.get: Takes the static resource img/vona.png as input, generates the path /api/static/demo/student/img/vona.png

Get the static resource URL

class ControllerStudent {
  test() {
    const url = this.scope.static.getURL('img/vona.png');
    assert.equal(url, 'http://localhost:7102/api/static/demo/student/img/vona.png);
  }
}

• static.getURL: Takes the static resource img/vona.png as input and generates the URL http://localhost:7102/api/static/demo/student/img/vona.png

URL Configuration

http://localhost:7102 is dynamically inferred by the system based on the current API context. In some application scenarios, the API Server's URL may differ from the domain name used to provide services. At this point, you can modify the URL configuration through App Config or Instance Config

1. App Config

src/backend/config/config/config.ts

// server
config.server = {
  serve: {
    protocol: 'https',
    host: 'cabloy.com',
  },
};

Then, executing the method static.getURL will return the URL https://cabloy.com/api/static/demo/student/img/vona.png

2. Instance Config

VonaJS supports multi-instance/multi-tenancy, allowing you to specify different configuration for specific instances.

// instance
config.instance = {
  instances: {
    '': {
      password: '',
      title: '',
      config: {
        server: {
          serve: {
            protocol: 'https',
            host: 'cabloy.com',
          },
        },
      },
    },
  },
};
