A typescript transpiler that convert golang's type to typescript's type. Help front-end developer to work faster in daily work. My target is to provide a website tool to convert static text written in Golang interface structure to TypeScript type definition. So the lex & parser can only parse the code about type definition, which is be designed following.

Design

Don't support anonymous type, which is useless in interface definition. We support common type definition in interface like

• Single Type
• JSON Tag
• Inline Structure
• Comment

About data type, communication between frontend and backend, we just have basic type, compound structure type, and array type.

Example

This is a golang type definition.

// comment 
type Height int // comment
type Person struct {
   Name string  //  comment
   Age uint8 // comment
   Height Height  // comment
   Birthday uint8 `json:"birthday"` 
   Parents []Person
   School struct {
     MiddleSchool string
     HighSchool string
     College string
   }
}

We can convert it to TypeScript definition.

// comment 
type Height = number // comment
type Person = { //  comment
  Name: string // comment
  Age: number // comment
  Height: Height  // comment
  birthday: number
  Parents: Person[]
  School: {
    MiddleSchool: string
    HighSchool: string
    College: string
  }
}

TODO

• alias go > 1.8 type A = string
• operator *
• map type map[string]string
