# Swagger Code Generator
|
|
|
|
[](https://travis-ci.org/swagger-api/swagger-codegen)
|
|
|
|
## Overview
|
|
This is the swagger codegen project, which allows generation of client libraries automatically from a Swagger-compliant server.
|
|
|
|
Check out [Swagger-Spec](https://github.com/swagger-api/swagger-spec) for additional information about the Swagger project, including additional libraries with support for other languages and more.
|
|
|
|
## Build and run using docker
|
|
|
|
```
|
|
git clone https://github.com/swagger-api/swagger-codegen
|
|
|
|
cd swagger-codegen
|
|
|
|
./run-in-docker.sh mvn package
|
|
```
|
|
|
|
Build a nodejs server stub:
|
|
|
|
```
|
|
./run-in-docker.sh generate \
|
|
-i http://petstore.swagger.io/v2/swagger.json \
|
|
-l nodejs \
|
|
-o samples/server/petstore/nodejs
|
|
```
|
|
|
|
## Compatibility
|
|
The Swagger Specification has undergone 3 revisions since initial creation in 2010. The swagger-codegen project has the following compatibilies with the swagger specification:
|
|

|
|
|
|
|
|
### Prerequisites
|
|
You need the following installed and available in your $PATH:
|
|
|
|
* [Java 7](http://java.oracle.com)
|
|
|
|
* [Apache maven 3.0.3 or greater](http://maven.apache.org/)
|
|
|
|
#### OS X Users
|
|
Don't forget to install Java 7. You probably have 1.6 or 1.8.
|
|
|
|
Export JAVA_HOME in order to user proper Java version:
|
|
```
|
|
export JAVA_HOME=`/usr/libexec/java_home -v 1.7`
|
|
export PATH=${JAVA_HOME}/bin:$PATH
|
|
```
|
|
|
|
#### Building
|
|
|
|
After cloning the project, you can build it from source with this command:
|
|
|
|
```
|
|
mvn package
|
|
```
|
|
|
|
### To generate a sample client library
|
|
You can build a client against the swagger sample [petstore](http://petstore.swagger.io) API as follows:
|
|
|
|
```
|
|
./bin/java-petstore.sh
|
|
```
|
|
|
|
This will run the generator with this command:
|
|
|
|
```
|
|
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
|
|
-i http://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:
|
|
|
|
```
|
|
NAME
|
|
swagger generate - Generate code with chosen lang
|
|
|
|
SYNOPSIS
|
|
swagger generate [(-a <authorization> | --auth <authorization>)]
|
|
[(-c <configuration file> | --config <configuration file>)]
|
|
[-D <system properties>]
|
|
(-i <spec file> | --input-spec <spec file>)
|
|
(-l <language> | --lang <language>)
|
|
[(-o <output directory> | --output <output directory>)]
|
|
[(-t <template directory> | --template-dir <template directory>)]
|
|
[(-v | --verbose)]
|
|
[(-s | --skip-overwrite)]
|
|
|
|
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
|
|
|
|
-c <configuration file>, --config <configuration file>
|
|
Path to json configuration file. File content should be in a json
|
|
format {"optionKey":"optionValue", "optionKey1":"optionValue1"...}
|
|
Supported options can be different for each language. Run
|
|
config-help -l {lang} command for language specific config options.
|
|
|
|
-D <system properties>
|
|
sets specified system properties in the format of
|
|
name=value,name=value
|
|
|
|
-i <spec file>, --input-spec <spec file>
|
|
location of the swagger spec, as URL or file (required)
|
|
|
|
-l <language>, --lang <language>
|
|
client language to generate (maybe class name in classpath,
|
|
required)
|
|
|
|
-o <output directory>, --output <output directory>
|
|
where to write the generated files (current dir by default)
|
|
|
|
-t <template directory>, --template-dir <template directory>
|
|
folder containing the template files
|
|
|
|
-v, --verbose
|
|
verbose mode
|
|
|
|
-s , --skip-overwrite
|
|
specifies if the existing files should be overwritten during
|
|
the generation
|
|
```
|
|
|
|
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
|
|
```
|
|
|
|
### Generating libraries from your server
|
|
It's just as easy--just use the `-i` flag to point to either a server or file.
|
|
|
|
### Modifying the client library format
|
|
Don't like the default swagger client syntax? Want a different language supported? No problem! Swagger codegen processes mustache templates with the [jmustache](https://github.com/samskivert/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.
|
|
|
|
### Making your own codegen modules
|
|
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-distribution/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.
|
|
|
|
### Where is Javascript???
|
|
See our [javascript library](http://github.com/swagger-api/swagger-js)--it's completely dynamic and doesn't require
|
|
static code generation.
|
|
There is a third-party component called [swagger-js-codegen](https://github.com/wcandillon/swagger-js-codegen) that can generate angularjs or nodejs source code from a swagger specification.
|
|
|
|
|
|
#### Generating a client from flat files (i.e. no remote server calls)
|
|
If you don't want to call your server, you can save the swagger 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](http://editor.swagger.io)... or while coding on an airplane.
|
|
|
|
### Customizing the generator
|
|
|
|
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/
|
|
AkkaScalaClientCodegen.java
|
|
AndroidClientCodegen.java
|
|
AsyncScalaClientCodegen.java
|
|
CSharpClientCodegen.java
|
|
FlashClientCodegen.java
|
|
JavaClientCodegen.java
|
|
JaxRSServerCodegen.java
|
|
NodeJSServerCodegen.java
|
|
ObjcClientCodegen.java
|
|
PerlClientCodegen.java
|
|
PhpClientCodegen.java
|
|
Python3ClientCodegen.java
|
|
PythonClientCodegen.java
|
|
Qt5CPPGenerator.java
|
|
RetrofitClientCodegen.java
|
|
RubyClientCodegen.java
|
|
ScalaClientCodegen.java
|
|
ScalatraServerCodegen.java
|
|
SpringMVCServerCodegen.java
|
|
StaticDocCodegen.java
|
|
StaticHtmlGenerator.java
|
|
SwaggerGenerator.java
|
|
SwaggerYamlGenerator.java
|
|
SwiftCodegen.java
|
|
TizenClientCodegen.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 http://petstore.swagger.io/v2/swagger.json \
|
|
-l java \
|
|
-o samples/client/petstore/java \
|
|
-c path/to/config.json
|
|
```
|
|
Supported config options can be different per language. Running `config-help -l {lang}` will show available options.
|
|
|
|
```
|
|
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
|
|
|
|
invokerPackage
|
|
root package for generated code
|
|
|
|
groupId
|
|
groupId in generated pom.xml
|
|
|
|
artifactId
|
|
artifactId in generated pom.xml
|
|
|
|
artifactVersion
|
|
artifact version in generated pom.xml
|
|
|
|
sourceFolder
|
|
source folder for generated code
|
|
|
|
library
|
|
library template (sub-template) to use:
|
|
<default> - HTTP client: Jersey client 1.18. JSON processing: Jackson 2.4.2
|
|
jersey2 - HTTP client: Jersey client 2.6
|
|
```
|
|
|
|
Your config file for java can look like
|
|
|
|
```
|
|
{
|
|
"groupId":"com.my.company",
|
|
"artifactId":"MyClent",
|
|
"artifactVersion":"1.2.0"
|
|
}
|
|
```
|
|
|
|
For all the unspecified options default values will be used.
|
|
|
|
Another way to override default options is to extend config class for 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.
|
|
|
|
### Validating your swagger spec
|
|
|
|
You have options. The easiest is to use our [online validator](https://github.com/swagger-api/validator-badge) 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:
|
|
|
|
http://online.swagger.io/validator/debug?url=http://petstore.swagger.io/v2/swagger.json
|
|
|
|
### Generating dynamic html api documentation
|
|
|
|
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.
|
|
|
|
|
|
### Generating static html api documentation
|
|
|
|
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
|
|
```
|
|
|
|
|
|
### To build a server stub
|
|
|
|
You can also use the codegen to generate a server for a couple different frameworks. Take a look here:
|
|
|
|
### node.js
|
|
```
|
|
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
|
|
-i http://petstore.swagger.io/v2/swagger.json \
|
|
-l nodejs \
|
|
-o samples/server/petstore/nodejs
|
|
```
|
|
|
|
### rails-grape
|
|
#### Not yet migrated to this branch
|
|
|
|
|
|
### scala scalatra
|
|
```
|
|
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
|
|
-i http://petstore.swagger.io/v2/swagger.json \
|
|
-l scalatra \
|
|
-o samples/server/petstore/scalatra
|
|
```
|
|
|
|
### java jax-rs
|
|
|
|
```
|
|
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
|
|
-i http://petstore.swagger.io/v2/swagger.json \
|
|
-l jaxrs \
|
|
-o samples/server/petstore/jaxrs
|
|
```
|
|
|
|
### java spring-mvc
|
|
|
|
```
|
|
java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
|
|
-i http://petstore.swagger.io/v2/swagger.json \
|
|
-l spring-mvc \
|
|
-o samples/server/petstore/spring-mvc
|
|
```
|
|
### To build the codegen library
|
|
|
|
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
