## Overview

OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs,  documentation and configuration automatically given an [OpenAPI Spec](https://github.com/OAI/OpenAPI-Specification) (both 2.0 and 3.0 are supported). Currently, the following languages/frameworks are supported:

### [1.3 - Download JAR](#table-of-contents)
<!-- RELEASE_VERSION -->
If you're looking for the latest stable version, you can grab it directly from Maven.org (Java 11 runtime at a minimum):

JAR location: `https://repo1.maven.org/maven2/org/openapitools/openapi-generator-cli/7.19.0/openapi-generator-cli-7.19.0.jar`

For **Mac/Linux** users:
```sh
wget https://repo1.maven.org/maven2/org/openapitools/openapi-generator-cli/7.19.0/openapi-generator-cli-7.19.0.jar -O openapi-generator-cli.jar
```

For **Windows** users, you will need to install [wget](http://gnuwin32.sourceforge.net/packages/wget.htm) or you can use Invoke-WebRequest in PowerShell (3.0+), e.g.
```
Invoke-WebRequest -OutFile openapi-generator-cli.jar https://repo1.maven.org/maven2/org/openapitools/openapi-generator-cli/7.19.0/openapi-generator-cli-7.19.0.jar
```

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

For Mac users, please make sure Java 11 is installed (Tips: run `java -version` to check the version), and export `JAVA_HOME` in order to use the supported Java version:
```sh
export JAVA_HOME=`/usr/libexec/java_home -v 1.11`
export PATH=${JAVA_HOME}/bin:$PATH
```

<!-- /RELEASE_VERSION -->
### Launcher Script

One downside to manual jar downloads is that you don't keep up-to-date with the latest released version. We have a Bash launcher script at [bin/utils/openapi-generator.cli.sh](./bin/utils/openapi-generator-cli.sh) which resolves this issue.

To install the launcher script, copy the contents of the script to a location on your path and make the script executable.

An example of setting this up (NOTE: Always evaluate scripts curled from external systems before executing them).

```
mkdir -p ~/bin/openapitools
curl https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/bin/utils/openapi-generator-cli.sh > ~/bin/openapitools/openapi-generator-cli
chmod u+x ~/bin/openapitools/openapi-generator-cli
export PATH=$PATH:~/bin/openapitools/
```

Now, `openapi-generator-cli` is "installed". On invocation, it will query the GitHub repository for the most recently released version. If this matches the last downloaded jar,
it will execute as normal. If a newer version is found, the script will download the latest release and execute it.

If you need to invoke an older version of the generator, you can define the variable `OPENAPI_GENERATOR_VERSION` either ad hoc or globally. You can export this variable if you'd like to persist a specific release version.

Examples:

```
# Execute latest released openapi-generator-cli
openapi-generator-cli version

# Execute version 4.1.0 for the current invocation, regardless of the latest released version
OPENAPI_GENERATOR_VERSION=4.1.0 openapi-generator-cli version

# Execute version 4.1.0-SNAPSHOT for the current invocation
OPENAPI_GENERATOR_VERSION=4.1.0-SNAPSHOT openapi-generator-cli version

# Execute version 4.0.2 for every invocation in the current shell session
export OPENAPI_GENERATOR_VERSION=4.0.2
openapi-generator-cli version # is 4.0.2
openapi-generator-cli version # is also 4.0.2

# To "install" a specific version, set the variable in .bashrc/.bash_profile
echo "export OPENAPI_GENERATOR_VERSION=4.0.2" >> ~/.bashrc
source ~/.bashrc
openapi-generator-cli version # is always 4.0.2, unless any of the above overrides are done ad hoc
```

### [1.4 - Build Projects](#table-of-contents)

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

* [Java 11](https://adoptium.net/)

* [Apache Maven 3.8.8 or greater](https://maven.apache.org/) (optional)

After cloning the project, you can build it from source using [maven wrapper](https://maven.apache.org/wrapper/):

- Linux: `./mvnw clean install`
- Windows: `mvnw.cmd clean install`

#### Nix users

If you're a nix user, you can enter OpenAPI Generator shell, by typing:
```sh
nix develop
```
It will enter a shell with Java 11 installed.

Direnv supports automatically loading of the nix developer shell, so if you're using direnv too, type:
```sh
direnv allow
```
and have `java` and `mvn` set up with correct versions each time you enter project directory.

The default build contains minimal static analysis (via CheckStyle). To run your build with PMD and Spotbugs, use the `static-analysis` profile:

- Linux: `./mvnw -Pstatic-analysis clean install`
- Windows: `mvnw.cmd -Pstatic-analysis clean install`

### [1.5 - Homebrew](#table-of-contents)

To install, run `brew install openapi-generator`

Here is an example usage to generate a Ruby client:
```sh
openapi-generator generate -i https://raw.githubusercontent.com/openapitools/openapi-generator/master/modules/openapi-generator/src/test/resources/3_0/petstore.yaml -g ruby -o /tmp/test/
```

To reinstall with the latest master, run `brew uninstall openapi-generator && brew install --HEAD openapi-generator`

To install OpenJDK (pre-requisites), please run
```sh

### [1.6 - Docker](#table-of-contents)

#### Public Pre-built Docker images

 - [https://hub.docker.com/r/openapitools/openapi-generator-cli/](https://hub.docker.com/r/openapitools/openapi-generator-cli/) (official CLI)
 - [https://hub.docker.com/r/openapitools/openapi-generator-online/](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:

```sh
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/3_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:

```sh
# Start container at port 8888 and save the container id
> CID=$(docker run -d -p 8888:8080 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/3_0/petstore.yaml"}' \
'http://localhost:8888/api/gen/clients/ruby'

{"code":"c2d483.3.4672-40e9-91df-b9ffd18d22b8","link":"http://localhost:8888/api/gen/download/c2d483.3.4672-40e9-91df-b9ffd18d22b8"}

# Download the generated zip file
> wget http://localhost:8888/api/gen/download/c2d483.3.4672-40e9-91df-b9ffd18d22b8

# Unzip the file
> unzip c2d483.3.4672-40e9-91df-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`:

```sh
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:

```sh
./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 generate -i modules/openapi-generator/src/test/resources/3_0/petstore.yaml \
    -g go -o /gen/out/go-petstore -p packageName=petstore # generates go client, outputs locally to ./out/go-petstore
```

##### Troubleshooting

If an error like this occurs, just execute the **./mvnw clean install -U** command:

> org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.19.1:test (default-test) on project openapi-generator: A type incompatibility occurred while executing org.apache.maven.plugins:maven-surefire-plugin:2.19.1:test: java.lang.ExceptionInInitializerError cannot be cast to java.io.IOException

```sh
./run-in-docker.sh ./mvnw clean install -U
```

> Failed to execute goal org.fortasoft:gradle-maven-plugin:1.0.8:invoke (default) on project openapi-generator-gradle-plugin-mvn-wrapper: org.gradle.tooling.BuildException: Could not execute build using Gradle distribution 'https://services.gradle.org/distributions/gradle-4.7-bin.zip'

Right now: no solution for this one :|

#### Run Docker in Vagrant
Prerequisite: install [Vagrant](https://www.vagrantup.com/downloads.html) and [VirtualBox](https://www.virtualbox.org/wiki/Downloads).
 ```sh
git clone https://github.com/openapitools/openapi-generator.git
cd openapi-generator
vagrant up
vagrant ssh
cd /vagrant
./run-in-docker.sh ./mvnw package
```

### [1.7 - NPM](#table-of-contents)

There is also an [NPM package wrapper](https://www.npmjs.com/package/@openapitools/openapi-generator-cli) available for different platforms (e.g. Linux, Mac, Windows). (JVM is still required)
Please see the [project's README](https://github.com/openapitools/openapi-generator-cli) there for more information.

## [2 - Getting Started](#table-of-contents)

To generate a PHP client for [petstore.yaml](https://raw.githubusercontent.com/openapitools/openapi-generator/master/modules/openapi-generator/src/test/resources/3_0/petstore.yaml), please run the following
```sh
git clone https://github.com/openapitools/openapi-generator
cd openapi-generator
./mvnw 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/3_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/3_0/petstore.yaml -g php -o c:\temp\php_api_client`)

<!-- RELEASE_VERSION -->
You can also download the JAR (latest release) directly from [maven.org](https://repo1.maven.org/maven2/org/openapitools/openapi-generator-cli/7.19.0/openapi-generator-cli-7.19.0.jar)
<!-- /RELEASE_VERSION -->

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](#table-of-contents)

### To generate a sample client library
You can build a client against the [Petstore API](https://raw.githubusercontent.com/openapitools/openapi-generator/master/modules/openapi-generator/src/test/resources/3_0/petstore.yaml) as follows:

```sh
./bin/generate-samples.sh ./bin/configs/java-okhttp-gson.yaml
```

(On Windows, please install [GIT Bash for Windows](https://gitforwindows.org/) to run the command above)

This script uses the default library, which is `okhttp-gson`. It will run the generator with this command:

```sh
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/3_0/petstore.yaml \
  -g java \
  -t modules/openapi-generator/src/main/resources/Java \
  --additional-properties artifactId=petstore-okhttp-gson,hideGenerationTimestamp=true \
  -o samples/client/petstore/java/okhttp-gson
```

with a number of options. [The java options are documented here.](docs/generators/java.md)

You can also get the options with the `help generate` command (below only shows partial results):

## [6 - About Us](#table-of-contents)

What's the design philosophy or principle behind OpenAPI Generator?

We focus on developer experience. The generators should produce code, config, documentation, and more that are easily understandable and consumable by users. We focused on simple use cases to start with (bottom-up approach). Since then the project and the community have grown a lot: 600k weekly downloads via NPM CLI wrapper, 30M downloads via openapi-generator-cli docker image just to highlight a few. We've gradually supported more features (e.g. oneOf, anyOf introduced in OpenAPI 3.0) in various generators and we will continue this approach to deliver something based on our understanding of user demand and what they want, and continue to add support of new features introduced in OpenAPI specification (such as v3.1 and future versions of the OpenAPI specification).

### [6.1 - OpenAPI Generator Core Team](#table-of-contents)

OpenAPI Generator core team members are contributors who have been making significant contributions (review issues, fix bugs, make enhancements, etc) to the project on a regular basis.

### [6.3 - History of OpenAPI Generator](#table-of-contents)

OpenAPI Generator is a fork of [Swagger Codegen](https://github.com/swagger-api/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](docs/qna.md) for more information.
