Also you can use npx:

 npx swagger-typescript-api -p ./swagger.json -o ./src -n myApi.ts

You can use this package from nodejs:

const { generateApi } = require('swagger-typescript-api');

// example with url  
generateApi({
  name: "MySuperbApi.ts", // name of output typescript file
  url: 'http://api.com/swagger.json', // url where located swagger schema
})
  .then(({ files, configuration }) => {
    files.forEach(({ content, name }) => {
      fs.writeFile(path, content);
    });
  })
  .catch(e => console.error(e))

// example with local file  
generateApi({
  name: "ApiModule.ts", // name of output typescript file
  input: resolve(process.cwd(), './foo/swagger.json') // path to swagger schema
})
  .then(({ files, configuration }) => {
    files.forEach(({ content, name }) => {
      fs.writeFile(path, content);
    });
  })
  .catch(e => console.error(e))

// example with parsed schema  
generateApi({
  name: "ApiModule.ts", // name of output typescript file
  spec: {
    swagger: "2.0",
    info: {
      version: "1.0.0",
      title: "Swagger Petstore",
    },
    host: "petstore.swagger.io",
    basePath: "/api",
    schemes: ["http"],
    consumes: ["application/json"],
    produces: ["application/json"],
    paths: {
      // ...
    }
    // ...
  }
})
  .then(({ files, configuration }) => {
    files.forEach(({ content, name }) => {
      fs.writeFile(path, content);
    });
  })
  .catch(e => console.error(e))

💎 options

--templates

This option needed for cases when you don't want to use default swagger-typescript-api output structure

Templates:

• api.eta - Api class module
• data-contracts.eta - all types (data contracts) from swagger schema
• http-client.eta - HttpClient class module
• procedure-call.eta - route in Api class
• route-docs.eta - documentation for route in Api class
• route-name.eta - route name for route in Api class
• route-type.eta - (--route-types option)
• route-types.eta - (--route-types option)

How to use it:

1. copy swagger-typescript-api templates into your place in project
   • from /templates/default for single api file
   • from /templates/modular for multiple api files (with --modular option)
2. add --templates PATH_TO_YOUR_TEMPLATES option
3. modify ETA templates as you like

--module-name-index

This option should be used in cases when you have api with one global prefix like /api
Example:
GET:/api/fruits/getFruits
POST:/api/fruits/addFruits
GET:/api/vegetables/addVegetable
with --module-name-index 0 Api class will have one property api
When we change it to --module-name-index 1 then Api class have two properties fruits and vegetables
