Typescript Generated Types 👇

const OpenApiVersionExportName: {
    openapi31: string;
    openapi30: string;

}

🙂 Expected behavior

This is my expectation 👇

const OpenApiVersionExportName: {

This didn't change between 4.3 and 4.7 as far as I can tell. The current behavior is the expected behavior; if you want the "expected" behavior use as const either on the strings themselves or the entire object

export const OpenApiVersionExportName = {
  [OpenApiVersion.openapi31]: 'openapi',
  [OpenApiVersion.openapi30]: 'openapi',
  [OpenApiVersion.openapi2]: 'swagger',
} as const

我这如果真的，你是在和 4.3.7 之间变化。当前行为是没有行为；“潜在”行为as const，在字符串本身就是对象上使用

export const OpenApiVersionExportName = {
  [OpenApiVersion.openapi31]: 'openapi',
  [OpenApiVersion.openapi30]: 'openapi',
  [OpenApiVersion.openapi2]: 'swagger',
} as const

oh ！！ I am very sorry for wasting your precious time, it is my negligence that caused. 😖
