You can use this package from nodejs:

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

generateApi({
  name: "MySuperbApi.ts",

    onFormatRouteName: (routeInfo, templateRouteName) => {},
    onFormatTypeName: (typeName, rawTypeName) => {},
    onInit: (configuration) => {},
    onParseSchema: (originalSchema, parsedSchema) => {},
    onPrepareConfig: (currentConfiguration) => {},
  }
})
  .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 the default swagger-typescript-api output structure

Templates:

api.eta - Api class module (locations: /templates/default, /templates/modular)
data-contracts.eta - all types (data contracts) from swagger schema (locations: /templates/base)
http-client.eta - HttpClient class module (locations: /templates/base)
procedure-call.eta - route in Api class (locations: /templates/default, /templates/modular)
route-docs.eta - documentation for route in Api class (locations: /templates/base)
route-name.eta - route name for route in Api class (locations: /templates/base)
route-type.eta - (--route-types option) (locations: /templates/base)
route-types.eta - (--route-types option) (locations: /templates/base)

How to use it:

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)
- from /templates/base for base templates (templates using both in default and modular)
add --templates PATH_TO_YOUR_TEMPLATES option
modify ETA templates as you like

NOTE:
Eta has special directive to render template in your Eta templates - includeFile(pathToTemplate, payload)
If you want to use some default templates from this tool you can use path prefixes: @base, @default, @modular.
@base - path to base templates
@default - path to single api file templates
@modular - path to multiple api files templates
Examples:
- includeFile("@base/data-contracts.eta", configuration)
- includeFile("@default/api.eta", configuration)
- includeFile("@default/procedure-call.eta", configuration)
- includeFile("@modular/api.eta", configuration)
- includeFile("@modular/procedure-call.eta", configuration)
- includeFile("@base/route-docs.eta", configuration)
- includeFile("@base/route-name.eta", configuration)
- includeFile("@base/route-type.eta", configuration)
- includeFile("@base/route-types.eta", configuration)

`--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

`--module-name-first-tag`

This option will group your API operations based on their first tag - mirroring how the Swagger UI groups displayed operations
