# Swagger generated server ## Overview Using the swagger-codegen, you can not only generate clients but servers as well! The same spec can be used to drive your development both ways. This is an example of generating a server for `node.js`. ### Prerequisites You need the following installed and available in your $PATH:
  • - Scala 2.9.1 [available here](http://www.scala-lang.org) You also need to add scala binary to your PATH. ### Generating a server You first need to build the `swagger-codegen` project--this is done by running this command at the root of the swagger-codegen project: ``` mvn package ``` You can now generate a server from any valid[**](https://github.com/wordnik/swagger-codegen/blob/master/README.md#validating-your-swagger-spec) swagger spec: ``` ./bin/runscala.sh samples/server-generator/sinatra/SinatraServerGenerator.scala http://petstore.swagger.wordnik.com/api/resources.json special-key ``` After executing this script, you will have an output directory with the server-generated files: ``` $ cd samples/server-generator/sinatra/output $ find . -type f ./config.ru ./Gemfile ./Gemfile.lock ./lib/pet_api.rb ./lib/store_api.rb ./lib/swaggering.rb ./lib/user_api.rb ./my_app.rb ./README.md ``` To run the server, cd to the `samples/server-generator/sinatra/output` folder and run: ``` rackup -p 4567 ``` You can now load the swagger-ui against `http://localhost:4567/resources.json`. Of course this isn't a fully runnable server! You have to add the logic in the lib/*.rb files. But that's the easy part. ### Making it your own Running the sample is easy, but how about making your own server? Easy! Just modify the `samples/server-generator/sinatra/SinatraServerGenerator.scala` file. Don't like the templates? Don't worry, we're not offended! They're [mustache](http://mustache.github.com/) templates and are easy to modify. Take a look at the sample templates here:
  • - Generator for your api classes: [api.mustache](https://github.com/wordnik/swagger-codegen/blob/master/samples/server-generator/sinatra/templates/api.mustache)
  • - The main class to run your server: [my_app.mustache](https://github.com/wordnik/swagger-codegen/blob/master/samples/server-generator/sinatra/templates/my_app.mustache) Sound easy? It is!
