OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs, documentation and configuration automatically given an OpenAPI Spec (both 2.0 and 3.0 are supported). Please see OpenAPITools/openapi-generator
You need to execute openapi-generator-cli instead of openapi-generator from now on.
[added] semver support! 🎉
To make that happen, a version management was added to the package.
The first time you run the command openapi-generator-cli the last stable version
of OpenAPITools/openapi-generator is downloaded by default.
That version is saved in the file openapitools.json. Therefore you should include this file in your version control, to ensure that the correct version is being used next time you call the command.
If you would like to use a different version of the OpenAPITools/openapi-generator, you could change it by using one of the following commands:
openapi-generator-cli version-manager listopenapi-generator-cli version-manager set <versionTags...>
You will now be able to configure the code generation in openapitools.json. This makes it more convenient to generate code for every file that matches the given glob expression. For more information, please check out the configuration documentation below.
npm install @openapitools/openapi-generator-clior using yarn
yarn add @openapitools/openapi-generator-cliAfter the installation has finished you can run npx openapi-generator-cli or add a script like this:
{
"name": "my-cool-package",
"version": "0.0.0",
"scripts": {
"my-awesome-script-name": "openapi-generator-cli generate -i docs/openapi.yaml -g typescript-angular -o generated-sources/openapi --additional-properties=ngVersion=6.1.7,npmName=restClient,supportsES6=true,npmVersion=6.9.0,withInterfaces=true",
}
}Note the whitespace sensitivity when using multiple additional-properties:
--additional-properties=ngVersion=6.1.7,npmName=restClient,supportsES6=true,npmVersion=6.9.0,withInterfaces=true
npm install -g @openapitools/openapi-generator-clior using yarn
yarn global add @openapitools/openapi-generator-cliAfter the installation has finished you can run openapi-generator-cli
Mac/Linux:
openapi-generator-cli generate -g ruby -i https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator/src/test/resources/3_0/petstore.yaml -o /var/tmp/ruby-client
Windows:
openapi-generator-cli generate -g ruby -i https://raw.githubusercontent.com/OpenAPITools/openapi-generator/master/modules/openapi-generator/src/test/resources/3_0/petstore.yaml -o C:\temp\ruby-client
If you have installed the package locally and executed the command openapi-generator-cli at least once,
you will find a new file called openapitools.json along with the package.json. Please add this file to your VCS.
Initially the file has the following content:
{
"$schema": "node_modules/@openapitools/openapi-generator-cli/config.schema.json",
"spaces": 2,
"generator-cli": {
"version": "4.3.1" // or the current latest version ;)
}
}This configuration indicates the following:
- the json file shall be formatted using 2 spaces
- the jar files shall be downloaded to ./my/custom/storage/dir
- the generator-cli version 4.3.1 is used
Further it is also possible to configure generators, for example:
{
"$schema": "node_modules/@openapitools/openapi-generator-cli/config.schema.json",
"spaces": 2,
"generator-cli": {
"version": "4.3.1",
"storageDir": "~/my/custom/storage/dir", // optional
"generators": { // optional
"v2.0": { // any name you like (just printed to the console log or reference it using --generator-key)
"generatorName": "typescript-angular",
"output": "#{cwd}/output/v2.0/#{ext}/#{name}",
"glob": "examples/v2.0/{json,yaml}/*.{json,yaml}",
"additionalProperties": {
"ngVersion": "6.1.7",
"npmName": "restClient",
"supportsES6": "true",
"npmVersion": "6.9.0",
"withInterfaces": true
}
},
"v3.0": { // any name you like (just printed to the console log or reference it using --generator-key)
"generatorName": "typescript-fetch",
"output": "#{cwd}/output/v3.0/#{ext}/#{name}",
"glob": "examples/v3.0/petstore.{json,yaml}"
}
}
}
}If openapi-generator-cli generate is called without further arguments, then the configuration
is automatically used to generate your code. 🎉

Custom generators can be used by passing the --custom-generator=/my/custom-generator.jar argument.
