📔 The eBook A Beginner's Guide to Code Generation for REST APIs is a good starting point for begineers.

This is the swagger codegen project, which allows generation of API client libraries (SDK generation), server stubs and documentation automatically given an OpenAPI Spec. Currently, the following languages/frameworks are supported:

• API clients: ActionScript, Ada, Apex, Bash, C# (.net 2.0, 3.5 or later), C++ (cpprest, Qt5, Tizen), Clojure, Dart, Elixir, Elm, Eiffel, Erlang, Go, Groovy, Haskell (http-client, Servant), Java (Jersey1.x, Jersey2.x, OkHttp, Retrofit1.x, Retrofit2.x, Feign, RestTemplate, RESTEasy, Vertx, Google API Client Library for Java, Rest-assured), Kotlin, Lua, Node.js (ES5, ES6, AngularJS with Google Closure Compiler annotations) Objective-C, Perl, PHP, PowerShell, Python, R, Ruby, Rust (rust, rust-server), Scala (akka, http4s, swagger-async-httpclient), Swift (2.x, 3.x, 4.x), Typescript (Angular1.x, Angular2.x, Fetch, jQuery, Node)
• Server stubs: Ada, C# (ASP.NET Core, NancyFx), C++ (Pistache, Restbed), Erlang, Go, Haskell (Servant), Java (MSF4J, Spring, Undertow, JAX-RS: CDI, CXF, Inflector, RestEasy, Play Framework, PKMST), Kotlin, PHP (Lumen, Slim, Silex, Symfony, Zend Expressive), Python (Flask), NodeJS, Ruby (Sinatra, Rails5), Rust (rust-server), Scala (Finch, Lagom, Scalatra)
• API documentation generators: HTML, Confluence Wiki
• Configuration files: Apache2
• Others: JMeter

The OpenAPI Specification has undergone 3 revisions since initial creation in 2010. The swagger-codegen project has the following compatibilities with the OpenAPI Specification:

If you're looking for the latest stable version, you can grab it directly from Maven.org (Java 7 runtime at a minimum):

wget https://central.maven.org/maven2/io/swagger/swagger-codegen-cli/2.3.1/swagger-codegen-cli-2.3.1.jar -O swagger-codegen-cli.jar

java -jar swagger-codegen-cli.jar help

For Windows users, you will need to install wget or you can use Invoke-WebRequest in PowerShell (3.0+), e.g. Invoke-WebRequest -OutFile swagger-codegen-cli.jar https://central.maven.org/maven2/io/swagger/swagger-codegen-cli/2.3.1/swagger-codegen-cli-2.3.1.jar

On a mac, it's even easier with brew:

brew install swagger-codegen

To build from source, you need the following installed and available in your $PATH:

• Java 7 or 8

• Apache maven 3.3.3 or greater

Don't forget to install Java 7 or 8. You probably have 1.6.

Export JAVA_HOME in order to use the supported Java version:

export JAVA_HOME=`/usr/libexec/java_home -v 1.8`
export PATH=${JAVA_HOME}/bin:$PATH

After cloning the project, you can build it from source with this command:

mvn clean package

If you don't have maven installed, you may directly use the included maven wrapper, and build with the command:

./mvnw clean package

To install, run brew install swagger-codegen

Here is an example usage:

swagger-codegen generate -i https://petstore.swagger.io/v2/swagger.json -l ruby -o /tmp/test/

You can use run-in-docker.sh to do all development. This script maps your local repository to /gen in the docker container. It also maps ~/.m2/repository to the appropriate container location.

To execute mvn package:

git clone https://github.com/swagger-api/swagger-codegen
cd swagger-codegen
./run-in-docker.sh mvn package

Build artifacts are now accessible in your working directory.

Once built, run-in-docker.sh will act as an executable for swagger-codegen-cli. To generate code, you'll need to output to a directory under /gen (e.g. /gen/out). For example:

./run-in-docker.sh help # Executes 'help' command for swagger-codegen-cli
./run-in-docker.sh langs # Executes 'langs' command for swagger-codegen-cli
./run-in-docker.sh /gen/bin/go-petstore.sh  # Builds the Go client
./run-in-docker.sh generate -i modules/swagger-codegen/src/test/resources/2_0/petstore.yaml \
    -l go -o /gen/out/go-petstore -DpackageName=petstore # generates go client, outputs locally to ./out/go-petstore

Prerequisite: install Vagrant and VirtualBox.

git clone https://github.com/swagger-api/swagger-codegen.git
cd swagger-codegen
vagrant up
vagrant ssh
cd /vagrant
./run-in-docker.sh mvn package

• https://hub.docker.com/r/swaggerapi/swagger-generator/ (official web service)
• https://hub.docker.com/r/swaggerapi/swagger-codegen-cli/ (official CLI)

The Swagger Generator image can act as a self-hosted web application and API for generating code. This container can be incorporated into a CI pipeline, and requires at least two HTTP requests and some docker orchestration to access generated code.

Example usage (note this assumes jq is installed for command line processing of JSON):

# Start container and save the container id
CID=$(docker run -d swaggerapi/swagger-generator)
# allow for startup
sleep 5
# Get the IP of the running container
GEN_IP=$(docker inspect --format '{{.NetworkSettings.IPAddress}}'  $CID)
# Execute an HTTP request and store the download link
RESULT=$(curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{
  "swaggerUrl": "https://petstore.swagger.io/v2/swagger.json"
}' 'https://localhost:8188/api/gen/clients/javascript' | jq '.link' | tr -d '"')
# Download the generated zip and redirect to a file
curl $RESULT > result.zip
# Shutdown the swagger generator image
docker stop $CID && docker rm $CID

In the example above, result.zip will contain the generated client.

The Swagger Codegen image acts as a standalone executable. It can be used as an alternative to installing via homebrew, or for developers who are unable to install Java or upgrade the installed version.

To generate code with this image, you'll need to mount a local location as a volume.

Example:

docker run --rm -v ${PWD}:/local swaggerapi/swagger-codegen-cli generate \
    -i https://petstore.swagger.io/v2/swagger.json \
    -l go \
    -o /local/out/go

The generated code will be located under ./out/go in the current directory.

To generate a PHP client for https://petstore.swagger.io/v2/swagger.json, please run the following

git clone https://github.com/swagger-api/swagger-codegen
cd swagger-codegen
mvn clean package
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
   -i https://petstore.swagger.io/v2/swagger.json \
   -l php \
   -o /var/tmp/php_api_client

(if you're on Windows, replace the last command with java -jar modules\swagger-codegen-cli\target\swagger-codegen-cli.jar generate -i https://petstore.swagger.io/v2/swagger.json -l php -o c:\temp\php_api_client)

You can also download the JAR (latest release) directly from maven.org

To get a list of general options available, please run java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar help generate

To get a list of PHP specified options (which can be passed to the generator with a config file via the -c option), please run java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar config-help -l php

You can build a client against the swagger sample petstore API as follows:

./bin/java-petstore.sh

(On Windows, run .\bin\windows\java-petstore.bat instead)

This will run the generator with this command:

java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
  -i https://petstore.swagger.io/v2/swagger.json \
  -l java \
  -o samples/client/petstore/java

with a number of options. You can get the options with the help generate command (below only shows partial results):

                [--type-mappings <type mappings>...] [(-v | --verbose)]

OPTIONS
        -a <authorization>, --auth <authorization>
            adds authorization headers when fetching the swagger definitions
            remotely. Pass in a URL-encoded string of name:header with a comma
            separating multiple values

...... (results omitted)

        -v, --verbose
            verbose mode

You can then compile and run the client, as well as unit tests against it:

cd samples/client/petstore/java
mvn package

Other languages have petstore samples, too:

./bin/android-petstore.sh
./bin/java-petstore.sh
./bin/objc-petstore.sh

It's just as easy--just use the -i flag to point to either a server or file.

Don't like the default swagger client syntax? Want a different language supported? No problem! Swagger codegen processes mustache templates with the jmustache engine. You can modify our templates or make your own.

You can look at modules/swagger-codegen/src/main/resources/${your-language} for examples. To make your own templates, create your own files and use the -t flag to specify your template folder. It actually is that easy.

If you're starting a project with a new language and don't see what you need, swagger-codegen can help you create a project to generate your own libraries:

java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar meta \
  -o output/myLibrary -n myClientCodegen -p com.my.company.codegen

This will write, in the folder output/myLibrary, all the files you need to get started, including a `README.md. Once modified and compiled, you can load your library with the codegen and generate clients with your own, custom-rolled logic.

You would then compile your library in the output/myLibrary folder with mvn package and execute the codegen like such:

java -cp output/myLibrary/target/myClientCodegen-swagger-codegen-1.0.0.jar:modules/swagger-codegen-cli/target/swagger-codegen-cli.jar io.swagger.codegen.SwaggerCodegen

For Windows users, you will need to use ; instead of : in the classpath, e.g.

java -cp output/myLibrary/target/myClientCodegen-swagger-codegen-1.0.0.jar;modules/swagger-codegen-cli/target/swagger-codegen-cli.jar io.swagger.codegen.SwaggerCodegen

Note the myClientCodegen is an option now, and you can use the usual arguments for generating your library:

java -cp output/myLibrary/target/myClientCodegen-swagger-codegen-1.0.0.jar:modules/swagger-codegen-cli/target/swagger-codegen-cli.jar \
  io.swagger.codegen.SwaggerCodegen generate -l myClientCodegen\
  -i https://petstore.swagger.io/v2/swagger.json \
  -o myClient

See our javascript library--it's completely dynamic and doesn't require static code generation. There is a third-party component called swagger-js-codegen that can generate angularjs or nodejs source code from a OpenAPI Specification.

❗ On Dec 7th 2015, a Javascript API client generator has been added by @jfiala.

If you don't want to call your server, you can save the OpenAPI Spec files into a directory and pass an argument to the code generator like this:

-i ./modules/swagger-codegen/src/test/resources/2_0/petstore.json

Great for creating libraries on your ci server, from the Swagger Editor... or while coding on an airplane.

You may not want to generate all models in your project. Likewise you may want just one or two apis to be written. If that's the case, you can use system properties to control the output:

The default is generate everything supported by the specific library. Once you enable a feature, it will restrict the contents generated:

# generate only models
java -Dmodels {opts}

# generate only apis
java -Dapis {opts}

# generate only supporting files
java -DsupportingFiles

# generate models and supporting files
java -Dmodels -DsupportingFiles

To control the specific files being generated, you can pass a CSV list of what you want:

# generate the User and Pet models only
-Dmodels=User,Pet

# generate the User model and the supportingFile `StringUtil.java`:
-Dmodels=User -DsupportingFiles=StringUtil.java

To control generation of docs and tests for api and models, pass false to the option. For api, these options are -DapiTests=false and -DapiDocs=false. For models, -DmodelTests=false and -DmodelDocs=false. These options default to true and don't limit the generation of the feature options listed above (like -Dapi):

# generate only models (with tests and documentation)
java -Dmodels {opts}

# generate only models (with tests but no documentation)
java -Dmodels -DmodelDocs=false {opts}

# generate only User and Pet models (no tests and no documentation)
java -Dmodels=User,Pet -DmodelTests=false {opts}

# generate only apis (without tests)
java -Dapis -DapiTests=false {opts}

# generate only apis (modelTests option is ignored)
java -Dapis -DmodelTests=false {opts}

When using selective generation, only the templates needed for the specific generation will be used.

Swagger codegen supports a .swagger-codegen-ignore file, similar to .gitignore or .dockerignore you're probably already familiar with.

The ignore file allows for better control over overwriting existing files than the --skip-overwrite flag. With the ignore file, you can specify individual files or directories can be ignored. This can be useful, for example if you only want a subset of the generated code.

Examples:

# Swagger Codegen Ignore
# Lines beginning with a # are comments

# This should match build.sh located anywhere.
build.sh

# Matches build.sh in the root
/build.sh

# Exclude all recursively
docs/**

# Explicitly allow files excluded by other rules
!docs/UserApi.md

# Recursively exclude directories named Api
# You can't negate files below this directory.
src/**/Api/

# When this file is nested under /Api (excluded above),
# this rule is ignored because parent directory is excluded by previous rule.
!src/**/PetApiTests.cs

# Exclude a single, nested file explicitly
src/IO.Swagger.Test/Model/AnimalFarmTests.cs

The .swagger-codegen-ignore file must exist in the root of the output directory.

Upon first code generation, you may also pass the CLI option --ignore-file-override=/path/to/ignore_file for greater control over generated outputs. Note that this is a complete override, and will override the .swagger-codegen-ignore file in an output directory when regenerating code.

Editor support for .swagger-codegen-ignore files is available in IntelliJ via the .ignore plugin.

There are different aspects of customizing the code generator beyond just creating or modifying templates. Each language has a supporting configuration file to handle different type mappings, etc:

$ ls -1 modules/swagger-codegen/src/main/java/io/swagger/codegen/languages/
AbstractJavaJAXRSServerCodegen.java
AbstractTypeScriptClientCodegen.java
... (results omitted)
TypeScriptAngularClientCodegen.java
TypeScriptNodeClientCodegen.java

Each of these files creates reasonable defaults so you can get running quickly. But if you want to configure package names, prefixes, model folders, etc. you can use a json config file to pass the values.

java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
  -i https://petstore.swagger.io/v2/swagger.json \
  -l java \
  -o samples/client/petstore/java \
  -c path/to/config.json

and config.json contains the following as an example:

{
  "apiPackage" : "petstore"
}

Supported config options can be different per language. Running config-help -l {lang} will show available options. These options are applied via configuration file (e.g. config.json) or by passing them with -D{optionName}={optionValue}. (If -D{optionName} does not work, please open a ticket and we'll look into it)

java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar config-help -l java

Output

CONFIG OPTIONS
	modelPackage
	    package for generated models

	apiPackage
	    package for generated api classes
...... (results omitted)
	library
	    library template (sub-template) to use:
	    jersey1 - HTTP client: Jersey client 1.18. JSON processing: Jackson 2.4.2
	    jersey2 - HTTP client: Jersey client 2.6
	    feign - HTTP client: Netflix Feign 8.1.1.  JSON processing: Jackson 2.6.3
	    okhttp-gson (default) - HTTP client: OkHttp 2.4.0. JSON processing: Gson 2.3.1
	    retrofit - HTTP client: OkHttp 2.4.0. JSON processing: Gson 2.3.1 (Retrofit 1.9.0)
        retrofit2 - HTTP client: OkHttp 2.5.0. JSON processing: Gson 2.4 (Retrofit 2.0.0-beta2)
        google-api-client - HTTP client: google-api-client 1.23.0. JSON processing: Jackson 2.8.9
        rest-assured - HTTP client: rest-assured : 3.1.0. JSON processing: Gson 2.6.1. Only for Java8 

Your config file for Java can look like

{
  "groupId":"com.my.company",
  "artifactId":"MyClient",
  "artifactVersion":"1.2.0",
  "library":"feign"
}

For all the unspecified options default values will be used.

Another way to override default options is to extend the config class for the specific language. To change, for example, the prefix for the Objective-C generated files, simply subclass the ObjcClientCodegen.java:

package com.mycompany.swagger.codegen;

import io.swagger.codegen.languages.*;

public class MyObjcCodegen extends ObjcClientCodegen {
    static {
        PREFIX = "HELO";
    }
}

and specify the classname when running the generator:

-l com.mycompany.swagger.codegen.MyObjcCodegen

Your subclass will now be loaded and overrides the PREFIX value in the superclass.

Sometimes you don't want a model generated. In this case, you can simply specify an import mapping to tell the codegen what not to create. When doing this, every location that references a specific model will refer back to your classes. Note, this may not apply to all languages...

To specify an import mapping, use the --import-mappings argument and specify the model-to-import logic as such:

--import-mappings Pet=my.models.MyPet

Or for multiple mappings:

--import-mappings Pet=my.models.MyPet,Order=my.models.MyOrder

or

--import-mappings Pet=my.models.MyPet --import-mappings Order=my.models.MyOrder

You have options. The easiest is to use our online validator which not only will let you validate your spec, but with the debug flag, you can see what's wrong with your spec. For example:

https://online.swagger.io/validator/debug?url=https://petstore.swagger.io/v2/swagger.json

To do so, just use the -l dynamic-html flag when reading a spec file. This creates HTML documentation that is available as a single-page application with AJAX. To view the documentation:

cd samples/dynamic-html/
npm install
node .

Which launches a node.js server so the AJAX calls have a place to go.

To do so, just use the -l html flag when reading a spec file. This creates a single, simple HTML file with embedded css so you can ship it as an email attachment, or load it from your filesystem:

cd samples/html/
open index.html

Please refer to https://github.com/swagger-api/swagger-codegen/wiki/Server-stub-generator-HOWTO for more information.

This will create the swagger-codegen library from source.

mvn package

Note! The templates are included in the library generated. If you want to modify the templates, you'll need to either repackage the library OR specify a path to your scripts

You can use the swagger-codegen-maven-plugin for integrating with your workflow, and generating any codegen target.

Gradle Swagger Generator Plugin is available for generating source code and API document.

To push the auto-generated SDK to GitHub, we provide git_push.sh to streamline the process. For example:

1. Create a new repository in GitHub (Ref: https://help.github.com/articles/creating-a-new-repository/)

2. Generate the SDK

 java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
 -i modules/swagger-codegen/src/test/resources/2_0/petstore.json -l perl \
 --git-user-id "wing328" \
 --git-repo-id "petstore-perl" \
 --release-note "Github integration demo" \
 -o /var/tmp/perl/petstore

3. Push the SDK to GitHub

cd /var/tmp/perl/petstore
/bin/sh ./git_push.sh

One can also generate API client or server using the online generators (https://generator.swagger.io)

For example, to generate Ruby API client, simply send the following HTTP request using curl:

curl -X POST -H "content-type:application/json" -d '{"swaggerUrl":"https://petstore.swagger.io/v2/swagger.json"}' https://generator.swagger.io/api/gen/clients/ruby

Then you will receieve a JSON response with the URL to download the zipped code.

To customize the SDK, you can POST to https://generator.swagger.io/gen/clients/{language} with the following HTTP body:

{
  "options": {},
  "swaggerUrl": "https://petstore.swagger.io/v2/swagger.json"
}

in which the options for a language can be obtained by submitting a GET request to https://generator.swagger.io/api/gen/clients/{language}:

For example, curl https://generator.swagger.io/api/gen/clients/python returns

{
  "packageName":{
    "opt":"packageName",
    "description":"python package name (convention: snake_case).",
    "type":"string",
    "default":"swagger_client"
  },
  "packageVersion":{
    "opt":"packageVersion",
    "description":"python package version.",
    "type":"string",
    "default":"1.0.0"
  },
  "sortParamsByRequiredFlag":{
    "opt":"sortParamsByRequiredFlag",
    "description":"Sort method arguments to place required parameters before optional parameters.",
    "type":"boolean",
    "default":"true"
  }
}

To set package name to pet_store, the HTTP body of the request is as follows:

{
  "options": {
    "packageName": "pet_store"
  },
  "swaggerUrl": "https://petstore.swagger.io/v2/swagger.json"
}

and here is the curl command:

curl -H "Content-type: application/json" -X POST -d '{"options": {"packageName": "pet_store"},"swaggerUrl": "https://petstore.swagger.io/v2/swagger.json"}' https://generator.swagger.io/api/gen/clients/python

Instead of using swaggerUrl with an URL to the OpenAPI/Swagger spec, one can include the spec in the JSON payload with spec, e.g.

{
  "options": {},
  "spec": {
    "swagger": "2.0",
    "info": {
      "version": "1.0.0",
      "title": "Test API"
    },
    ...
  }
}
