# Swagger to Typescript Codegen

[![Build Status](https://travis-ci.com/mtennoe/swagger-typescript-codegen.svg?branch=master)](https://travis-ci.com/mtennoe/swagger-typescript-codegen)

This package generates a TypeScript class from a [swagger specification file](https://github.com/wordnik/swagger-spec). The code is generated using [mustache templates](https://github.com/mtennoe/swagger-js-codegen/tree/master/lib/templates) and is quality checked by [jshint](https://github.com/jshint/jshint/) and beautified by [js-beautify](https://github.com/beautify-web/js-beautify).

The typescript generator is based on [superagent](https://github.com/visionmedia/superagent) and can be used for both nodejs and the browser via browserify/webpack.

This fork was made to simplify some parts, add some more features, and tailor it more to specific use cases.

## Installation
```bash
npm install @1stquad/swagger-typescript-codegen 
```

## Example
```javascript
var fs = require('fs');
var CodeGen = require('swagger-typescript-codegen').CodeGen;

var file = 'swagger/spec.json';
var swagger = JSON.parse(fs.readFileSync(file, 'UTF-8'));
var tsSourceCode = CodeGen.getTypescriptCode({ className: 'Test', swagger: swagger, imports: ['../../typings/tsd.d.ts'] });
console.log(tsSourceCode);
```

## Custom template
```javascript
var source = CodeGen.getCustomCode({
    moduleName: 'Test',
    className: 'Test',
    swagger: swaggerSpec,
    template: {
        class: fs.readFileSync('my-class.mustache', 'utf-8'),
        method: fs.readFileSync('my-method.mustache', 'utf-8'),
        type: fs.readFileSync('my-type.mustache', 'utf-8')
    }
});
```

## Options
In addition to the common options listed below, `getCustomCode()` *requires* a `template` field:

    template: { class: "...", method: "..." }

```

#### Custom Mustache Variables
You can also pass in your own variables for the mustache templates by adding a `mustache` object:

```javascript
var source = CodeGen.getCustomCode({
    ...
    mustache: {
      foo: 'bar',
      app_build_id: env.BUILD_ID,
      app_version: pkg.version
    }
});
```

## Swagger Extensions

### x-proxy-header
Some proxies and application servers inject HTTP headers into the requests.  Server-side code
may use these fields, but they are not required in the client API.

eg: https://cloud.google.com/appengine/docs/go/requests#Go_Request_headers

```yaml
  /locations:
    get:
      parameters:
      - name: X-AppEngine-Country
        in: header
        x-proxy-header: true
        type: string
        description: Provided by AppEngine eg - US, AU, GB
      - name: country
        in: query
        type: string
        description: |
          2 character country code.
          If not specified, will default to the country provided in the X-AppEngine-Country header
      ...
```

## Development

To run the typescript compiler on the source files run. This will start a watch process on the sources and build them into the `lib` folder.

```bash
npm run build:watch
```

In addition you can run the test watcher in a separate tab to run the tests in watch mode on the files in the `lib` folder.

```bash
npm run test:watch
```
