0.11.1-1 • Public • Published 3 years ago

  $ npm install --global reasonably-typed

Converts TypeScript and Flow definitions to Reason interfaces

Take your Flow or TypeScript definition

// class.js
declare module 'classes' {
  declare type State = {
    id: number,
    storeName: string
  };
 
  declare export class Store {
    constructor(initialState: State): Store;
    state: State;
    update(nextState: State): void;
  }
}

Run retyped

$ retyped compile class.js

Get Reason

/* Module classes */
 
type state = Js.t {. id : float, storeName : string};
 
module Store = {
  type t = Js.t {. state : state, update : (state => unit) [@bs.meth]};
  external make : state => t = "Store" [@@bs.new] [@@bs.module "classes"];
};

Examples

TypeScript

TypeScript has a similar workflow. Compile your TypeScript file with:

$ retyped compile my-definition.d.ts

FlowTyped

ReasonablyTyped can automatically compile all FlowTyped definitions in your repo. Run

$ retyped compile --flow-typed

Command-line Usage

retyped

Commands:
  compile [files...]  Generate BuckleScript interfaces from a file

ReasonablyTyped also exports a library for use! See the example below:

// lib-usage.js
import * as ReasonablyTyped from 'reasonably-typed'
 
const libSrc = fs.readFileSync('lib.js').toString()
const bsInterface = ReasonablyTyped.compile(libSrc)
