Swagger-UI accepts configuration parameters in four locations.
From lowest to highest precedence:
- The
swagger-config.yaml
in the project root directory, if it exists, is baked into the application - configuration object passed as an argument to Swagger-UI (
SwaggerUI({ ... })
) - configuration document fetched from a specified
configUrl
- configuration items passed as key/value pairs in the URL query string
Parameters with dots in their names are single strings used to organize subordinate parameters, and are not indicative of a nested structure.
For readability, parameters are grouped by category and sorted alphabetically.
Type notations are formatted like so:
String=""
means a String type with a default value of""
.String=["a"*, "b", "c", "d"]
means a String type that can bea
,b
,c
, ord
, with the*
indicating thata
is the default value.
Parameter Name | Description |
---|---|
configUrl |
String . URL to fetch external configuration document from. |
dom_id |
String , REQUIRED if domNode is not provided. The id of a dom element inside which SwaggerUi will put the user interface for swagger. |
domNode |
Element , REQUIRED if dom_id is not provided. The HTML DOM element inside which SwaggerUi will put the user interface for swagger. Overrides dom_id . |
spec |
Object={} . A JS object describing the OpenAPI Specification. When used, the url parameter will not be parsed. This is useful for testing manually-generated specifications without hosting them. |
url |
String . The url pointing to API definition (normally swagger.json or swagger.yaml ). Will be ignored if urls or spec is used. |
urls |
String . An array of API definition objects ({url: "<url>", name: "<name>"} ) used by Topbar plugin. When used and Topbar plugin is enabled, the url parameter will not be parsed. Names and URLs must be unique among all items in this array, since they're used as identifiers. |
urls.primaryName |
String . When using urls , you can use this subparameter. If the value matches the name of a spec provided in urls , that spec will be displayed when Swagger-UI loads, instead of defaulting to the first spec in urls . |
Read more about the plugin system in the Customization documentation.
Parameter Name | Description |
---|---|
layout |
String="BaseLayout" . The name of a component available via the plugin system to use as the top-level layout for Swagger-UI. |
plugins |
Array=[] . An array of plugin functions to use in Swagger-UI. |
presets |
Array=[SwaggerUI.presets.ApisPreset] . An array of presets to use in Swagger-UI. Usually, you'll want to include ApisPreset if you use this option. |
Parameter Name | Description |
---|---|
deepLinking |
Boolean=false . If set to true , enables deep linking for tags and operations. See the Deep Linking documentation for more information. |
displayOperationId |
Boolean=false . Controls the display of operationId in operations list. The default is false . |
defaultModelsExpandDepth |
Number=1 . The default expansion depth for models (set to -1 completely hide the models). |
defaultModelExpandDepth |
Number=1 . The default expansion depth for the model on the model-example section. |
defaultModelRendering |
String=["example"*, "model"] . Controls how the model is shown when the API is first rendered. (The user can always switch the rendering for a given model by clicking the 'Model' and 'Example Value' links.) |
displayRequestDuration |
Boolean=false . Controls the display of the request duration (in milliseconds) for Try-It-Out requests. |
docExpansion |
String=["list"*, "full", "none"] . Controls the default expansion setting for the operations and tags. It can be 'list' (expands only the tags), 'full' (expands the tags and operations) or 'none' (expands nothing). |
filter |
Boolean=false OR String . If set, enables filtering. The top bar will show an edit box that you can use to filter the tagged operations that are shown. Can be Boolean to enable or disable, or a string, in which case filtering will be enabled using that string as the filter expression. Filtering is case sensitive matching the filter expression anywhere inside the tag. |
maxDisplayedTags |
Number . If set, limits the number of tagged operations displayed to at most this many. The default is to show all operations. |
operationsSorter |
Function=(a => a) . Apply a sort to the operation list of each API. It can be 'alpha' (sort by paths alphanumerically), 'method' (sort by HTTP method) or a function (see Array.prototype.sort() to know how sort function works). Default is the order returned by the server unchanged. |
showExtensions |
Boolean=false . Controls the display of vendor extension (x- ) fields and values for Operations, Parameters, and Schema. |
tagsSorter |
Function=(a => a) . Apply a sort to the tag list of each API. It can be 'alpha' (sort by paths alphanumerically) or a function (see Array.prototype.sort() to learn how to write a sort function). Two tag name strings are passed to the sorter for each pass. Default is the order determined by Swagger-UI. |
Parameter Name | Description |
---|---|
oauth2RedirectUrl |
String . OAuth redirect URL. |
requestInterceptor |
Function=(a => a) . MUST be a function. Function to intercept remote definition, Try-It-Out, and OAuth2 requests. Accepts one argument requestInterceptor(request) and must return the potentially modified request. |
responseInterceptor |
Function=(a => a) . MUST be a function. Function to intercept remote definition, Try-It-Out, and OAuth2 responses. Accepts one argument responseInterceptor(response) and must return the potentially modified response. |
showMutatedRequest |
Boolean=true . If set to true , uses the mutated request returned from a requestInterceptor to produce the curl command in the UI, otherwise the request before the requestInterceptor was applied is used. |
supportedSubmitMethods |
Array=["get", "put", "post", "delete", "options", "head", "patch", "trace"] . List of HTTP methods that have the Try it out feature enabled. An empty array disables Try it out for all operations. This does not filter the operations from the display. |
validatorUrl |
String="https://online.swagger.io/validator" OR null . By default, Swagger-UI attempts to validate specs against swagger.io's online validator. You can use this parameter to set a different validator URL, for example for locally deployed validators (Validator Badge). Setting it to null will disable validation. |
Parameter Name | Description |
---|---|
modelPropertyMacro |
Function . Function to set default values to each property in model. Accepts one argument modelPropertyMacro(property), property is immutable |
parameterMacro |
Function . Function to set default value to parameters. Accepts two arguments parameterMacro(operation, parameter). Operation and parameter are objects passed for context, both remain immutable |
