CONFIG OPTIONS

These options may be applied as additional-properties (cli) or configOptions (plugins). Refer to configuration docs for more details.

OptionDescriptionValuesDefault
allowUnicodeIdentifiersboolean, toggles whether unicode identifiers are allowed in names or not, default is falsefalse
disallowAdditionalPropertiesIfNotPresentIf false, the 'additionalProperties' implementation (set to true by default) is compliant with the OAS and JSON schema specifications. If true (default), keep the old (incorrect) behaviour that 'additionalProperties' is set to false by default.
false
The 'additionalProperties' implementation is compliant with the OAS and JSON schema specifications.
true
Keep the old (incorrect) behaviour that 'additionalProperties' is set to false by default.
true
ensureUniqueParamsWhether to ensure parameter names are unique in an operation (rename parameters that are not).true
enumNameSuffixSuffix that will be appended to all enum names.Enum
enumPropertyNamingNaming convention for enum properties: 'camelCase', 'PascalCase', 'snake_case', 'UPPERCASE', and 'original'PascalCase
enumPropertyNamingReplaceSpecialCharSet to true to replace '-' and '+' symbols with 'minus' and 'plus' in enum of type stringfalse
enumUnknownDefaultCaseIf the server adds new enum cases, that are unknown by an old spec/client, the client will fail to parse the network response.With this option enabled, each enum will have a new case, 'unknown_default_open_api', so that when the server sends an enum case that is not known by the client/spec, they can safely fallback to this case.
false
No changes to the enum's are made, this is the default option.
true
With this option enabled, each enum will have a new case, 'unknown_default_open_api', so that when the enum case sent by the server is not known by the client/spec, can safely be decoded to this case.
false
fileContentDataTypeSpecifies the type to use for the content of a file - i.e. Blob (Browser, Deno) / Buffer (node)Buffer
frameworkSpecify the framework which should be used in the client code.
fetch-api
fetch-api
jquery
jquery
fetch-api
importFileExtensionFile extension to use with relative imports. Set it to '.js' or '.mjs' when using ESM. Defaults to '.ts' when 'platform' is set to 'deno'.null
legacyDiscriminatorBehaviorSet to false for generators with better support for discriminators. (Python, Java, Go, PowerShell, C# have this enabled by default).
true
The mapping in the discriminator includes descendent schemas that allOf inherit from self and the discriminator mapping schemas in the OAS document.
false
The mapping in the discriminator includes any descendent schemas that allOf inherit from self, any oneOf schemas, any anyOf schemas, any x-discriminator-values, and the discriminator mapping schemas in the OAS document AND Codegen validates that oneOf and anyOf schemas contain the required discriminator and throws an error if the discriminator is missing.
true
licenseNameThe name of the licenseUnlicense
modelPropertyNamingNaming convention for the property: 'camelCase', 'PascalCase', 'snake_case' and 'original', which keeps the original namecamelCase
npmNameThe name under which you want to publish generated npm package. Required to generate a full packagenull
npmRepositoryUse this property to set an url your private npmRepo in the package.jsonnull
npmVersionThe version of your npm package. If not provided, using the version from the OpenAPI specification file.1.0.0
nullSafeAdditionalPropsSet to make additional properties types declare that their indexer may return undefinedfalse
paramNamingNaming convention for parameters: 'camelCase', 'PascalCase', 'snake_case' and 'original', which keeps the original namecamelCase

prependFormOrBodyParametersAdd form or body parameters to the beginning of the parameter list.false
snapshotWhen setting this property to true, the version will be suffixed with -SNAPSHOT.yyyyMMddHHmmfalse
sortModelPropertiesByRequiredFlagSort model properties to place required parameters before optional parameters.true
sortParamsByRequiredFlagSort method arguments to place required parameters before optional parameters.true
supportsES6Generate code that conforms to ES6.false
useInversifyEnable this to generate decorators and service identifiers for the InversifyJS inversion of control container. If you set 'deno' as 'platform', the generator will process this value as 'disable'.false
useObjectParametersUse aggregate parameter objects as function arguments for api operations instead of passing each parameter as a separate function argument.false
useRxJSEnable this to internally use rxjs observables. If disabled, a stub is used instead. This is required for the 'angular' framework.false
