‼️ To migrate from Swagger Codegen to OpenAPI Generator, please refer to the migration guide ‼️

📔 For more information, please refer to the Wiki page and FAQ 📔

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

⚠️ If the OpenAPI spec is obtained from an untrusted source, please make sure you've reviewed the spec before using OpenAPI Generator to generate the API client, server stub or documentation as code injection may occur ⚠️

1.3 - Download JAR

If you're looking for the latest stable version, you can grab it directly from Maven.org (Java 8 runtime at a minimum):

JAR location: http://central.maven.org/maven2/org/openapitools/openapi-generator-cli/3.0.0/openapi-generator-cli-3.0.0.jar

For Mac/Linux users:

wget http://central.maven.org/maven2/org/openapitools/openapi-generator-cli/3.0.0/openapi-generator-cli-3.0.0.jar -O openapi-generator-cli.jar

For Windows users, you will need to install wget or you can use Invoke-WebRequest in PowerShell (3.0+), e.g.

Invoke-WebRequest -OutFile openapi-generator-cli.jar http://central.maven.org/maven2/org/openapitools/openapi-generator-cli/3.0.0/openapi-generator-cli-3.0.0.jar

After downloading the JAR, run java -jar openapi-generator-cli.jar help to show the usage.

For Mac users, please make sure Java 8 is installed (Tips: run java -version to check the version), and 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

1.4 - Build Projects

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

• Java 8

• Apache maven 3.3.3 or greater

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

mvn clean install

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

./mvnw clean install

1.5 - Homebrew

To install, run brew install openapi-generator (the new brew formula is pending https://github.com/Homebrew/homebrew-core/pull/28584)

Here is an example usage to generate a Ruby client:

openapi-generator generate -i https://raw.githubusercontent.com/openapitools/openapi-generator/master/modules/openapi-generator/src/test/resources/2_0/petstore.yaml -g ruby -o /tmp/test/

1.6 - Docker

Public Pre-built Docker images

• https://hub.docker.com/r/openapitools/openapi-generator-cli/ (official CLI)
• https://hub.docker.com/r/openapitools/openapi-generator-online/ (official web service)

OpenAPI Generator CLI Docker Image

The OpenAPI Generator 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 openapitools/openapi-generator-cli generate \
    -i https://raw.githubusercontent.com/openapitools/openapi-generator/master/modules/openapi-generator/src/test/resources/2_0/petstore.yaml \
    -g go \
    -o /local/out/go

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

OpenAPI Generator Online Docker Image

The openapi-generator-online 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:

# Start container at port 8888 and save the container id
> CID=$(docker run -d -p 8888:8080 -e GENERATOR_HOST=http://localhost:8888 openapitools/openapi-generator-online)

# allow for startup
> sleep 10

# Get the IP of the running container (optional)
GEN_IP=$(docker inspect --format '{{.NetworkSettings.IPAddress}}'  $CID)

# Execute an HTTP request to generate a Ruby client
> curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' \
-d '{"openAPIUrl": "https://raw.githubusercontent.com/openapitools/openapi-generator/master/modules/openapi-generator/src/test/resources/2_0/petstore.yaml"}' \
'http://localhost:8888/api/gen/clients/ruby'

{"code":"c2d483d3-3672-40e9-91df-b9ffd18d22b8","link":"http://localhost:8888/api/gen/download/c2d483d3-3672-40e9-91df-b9ffd18d22b8"}

# Download the generated zip file  
> wget http://localhost:8888/api/gen/download/c2d483d3-3672-40e9-91df-b9ffd18d22b8

# Unzip the file
> unzip c2d483d3-3672-40e9-91df-b9ffd18d22b8

# Shutdown the openapi generator image
> docker stop $CID && docker rm $CID

Development in docker

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/openapitools/openapi-generator
cd openapi-generator
./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 openapi-generator-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 openapi-generator-cli
./run-in-docker.sh list # Executes 'list' command for openapi-generator-cli
./run-in-docker.sh /gen/bin/go-petstore.sh  # Builds the Go client
./run-in-docker.sh generate -i modules/openapi-generator/src/test/resources/2_0/petstore.yaml \
    -g go -o /gen/out/go-petstore -DpackageName=petstore # generates go client, outputs locally to ./out/go-petstore

Run Docker in Vagrant

Prerequisite: install Vagrant and VirtualBox.

git clone http://github.com/openapitools/openapi-generator.git
cd openapi-generator
vagrant up
vagrant ssh
cd /vagrant
./run-in-docker.sh mvn package

2 - Getting Started

To generate a PHP client for petstore.yaml, please run the following

git clone https://github.com/openapitools/openapi-generator
cd openapi-generator
mvn clean package
java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar generate \
   -i https://raw.githubusercontent.com/openapitools/openapi-generator/master/modules/openapi-generator/src/test/resources/2_0/petstore.yaml \
   -g php \
   -o /var/tmp/php_api_client

(if you're on Windows, replace the last command with java -jar modules\openapi-generator-cli\target\openapi-generator-cli.jar generate -i https://raw.githubusercontent.com/openapitools/openapi-generator/master/modules/openapi-generator/src/test/resources/2_0/petstore.yaml -g 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/openapi-generator-cli/target/openapi-generator-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/openapi-generator-cli/target/openapi-generator-cli.jar config-help -g php

3 - Usage

To generate a sample client library

You can build a client against the 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/openapi-generator-cli/target/openapi-generator-cli.jar generate \
  -i https://raw.githubusercontent.com/openapitools/openapi-generator/master/modules/openapi-generator/src/test/resources/2_0/petstore.yaml \
  -g 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):

6.3 - History of OpenAPI Generator

OpenAPI Generator is a fork of Swagger Codegen. In view of the issues with the Swagger Codegen 3.0.0 (beta) release and the disagreement on the project's direction, more than 40 top contributors and template creators of Swagger Codegen decided to fork Swagger Codegen and maintain a community-driven version called "OpenAPI Generator". Please refer to the Q&A for more information.
