Don't create server if it was already created earlier.

[lynx-r]

Hello,

I'd like to suggest the pull request. It is about not creating http server if it was already created. I faced with this problem when I tried to use Restify with this library.

Do you have a Restify+aws-serverless-express example you can share? Are you calling createServer outside the handler?

There is an example of how I applied it:

export class ServerLambda extends ServerBase {
  private server: Server;

  bootstrap() {
    super.bootstrap();
    //create restify application
    this.app = new InversifyRestifyServer(container, {
      name: AppConstants.APP_NAME,
      version: nconf.get("server:api_version"),
      log: this.logger
    }).setConfig((app) => {
      this.config(app);
      this.configLambda(app);
    }).build();
    // this.configLambda(this.app);
  }

  private configLambda(app) {
    app.use(awsServerlessExpressMiddleware.eventContext());
    this.server = awsServerlessExpress.createServer(app, null, AppConstants.BINARY_MIME_TYPES);
  }

  handler(event, context) {
    awsServerlessExpress.proxy(this.server, event, context);
  }

}
