json2ts

json2ts converts JSON into valid Typescript classes with decorators.

Installation

If you have go already installed you can simply run

go get github.com/sno6/json2ts

If you prefer a binary, you can also find those in the releases section

Example

Take some JSON, such as this example from an HTTP response

{
  "data": [{
	  "status": "success",
	  "flag": true,
	  "array": [{
		  "ofData": "Also supports any level of depth!"
	  }]
  }]
}

Pass the JSON through json2ts

# Either from the clipboard (OSX)
>>> pbpaste | json2ts -d

# Or from a file
>>> json2ts -i my_file.json -d

and voila, your Typescript generated code

export class BaseClass {
	@IsDefined()
	@IsArray()
	@Type(() => Data)
	@ValidateNested({ each: true })
	public data!: Data[];
}

export class Data {
	@IsDefined()
	@IsString()
	public status!: string;

	@IsDefined()
	@IsBoolean()
	public flag!: boolean;

	@IsDefined()
	@IsArray()
	@Type(() => Array)
	@ValidateNested({ each: true })
	public array!: Array[];
}

export class Array {
	@IsDefined()
	@IsString()
	public ofData!: string;
}
