node ace docs:generate
command
✌️Usage
Create a file /config/swagger.ts
// for AdonisJS v6
import path from "node:path";
import url from "node:url";
// ---
export default {
// path: __dirname + "/../", for AdonisJS v5
path: path.dirname(url.fileURLToPath(import.meta.url)) + "/../", // for AdonisJS v6
title: "Foo", // use info instead
version: "1.0.0", // use info instead
description: "", // use info instead
tagIndex: 2,
info: {
title: "title",
version: "1.0.0",
description: "",
},
snakeCase: true,
debug: false, // set to true, to get some useful debug output
ignore: ["/swagger", "/docs"],
preferredPutPatch: "PUT", // if PUT/PATCH are provided for the same route, prefer PUT
common: {
parameters: {}, // OpenAPI conform parameters that are commonly used
headers: {}, // OpenAPI conform headers that are commonly used
},
securitySchemes: {}, // optional
authMiddlewares: ["auth", "auth:api"], // optional
defaultSecurityScheme: "BearerAuth", // optional
persistAuthorization: true, // persist authorization between reloads on the swagger page
showFullPath: false, // the path displayed after endpoint summary
};
In your routes.ts
6️⃣ for AdonisJS v6
import AutoSwagger from "adonis-autoswagger";
import swagger from "#config/swagger";
// returns swagger in YAML
router.get("/swagger", async () => {
return AutoSwagger.default.docs(router.toJSON(), swagger);
});
// Renders Swagger-UI and passes YAML-output of /swagger
router.get("/docs", async () => {
return AutoSwagger.default.ui("/swagger", swagger);
// return AutoSwagger.default.scalar("/swagger"); to use Scalar instead
// return AutoSwagger.default.rapidoc("/swagger", "view"); to use RapiDoc instead (pass "view" default, or "read" to change the render-style)
});
5️⃣ for AdonisJS v5
import AutoSwagger from "adonis-autoswagger";
import swagger from "Config/swagger";
// returns swagger in YAML
Route.get("/swagger", async () => {
return AutoSwagger.docs(Route.toJSON(), swagger);
});
// Renders Swagger-UI and passes YAML-output of /swagger
Route.get("/docs", async () => {
return AutoSwagger.ui("/swagger", swagger);
});

💡 Compatibility
For controllers to get detected properly, please load them lazily.
✅ const TestController = () => import('#controllers/test_controller')
❌ import TestController from '#controllers/test_controller'
🧑💻 Advanced usage
Additional configuration
info See Swagger API General Info for details.
securitySchemes
Add/Overwrite security schemes Swagger Authentication for details.
// example to override ApiKeyAuth
securitySchemes: {
ApiKeyAuth: {
type: "apiKey"
in: "header",
name: "X-API-Key"
}
}
defaultSecurityScheme
Override the default security scheme.
- BearerAuth
- BasicAuth
- ApiKeyAuth
- your own defined under
securitySchemes
authMiddlewares
If a route uses a middleware named auth
, auth:api
, AutoSwagger will detect it as a Swagger security method. However, you can implement other middlewares that handle authentication.
Modify generated output
Route.get("/myswagger", async () => {
const json = await AutoSwagger.json(Route.toJSON(), swagger);
// modify json to your hearts content
return AutoSwagger.jsonToYaml(json);
});
Route.get("/docs", async () => {
return AutoSwagger.ui("/myswagger", swagger);
});
Custom Paths in adonisJS v6
AutoSwagger supports the paths set in package.json
. Interfaces are expected to be in app/interfaces
. However, you can override this, by modifying package.json as follows.
//...
"imports": {
// ...
"#interfaces/*": "./app/custom/path/interfaces/*.js"
// ...
}
//...
📃 Configure
tagIndex
Tags endpoints automatically
- If your routes are
/api/v1/products/...
then your tagIndex should be3
- If your routes are
/v1/products/...
then your tagIndex should be2
- If your routes are
/products/...
then your tagIndex should be1
ignore
Ignores specified paths. When used with a wildcard (*), AutoSwagger will ignore everything matching before/after the wildcard.
/test/_
will ignore everything starting with/test/
, whereas \*/test
will ignore everything ending with/test
.
common
Sometimes you want to use specific parameters or headers on multiple responses.
Example: Some resources use the same filter parameters or return the same headers.
Here's where you can set these and use them with @paramUse()
and @responseHeader() @use()
. See practical example for further details.
💫 Extend Controllers
Add additional documentation to your Controller-files.
@summary (only one) A summary of what the action does
@tag (only one) Set a custom tag for this action
@description (only one) A detailed description of what the action does.
@operationId (only one) An optional unique string used to identify an operation. If provided, these IDs must be unique among all operations described in your API..
@responseBody (multiple)
Format: <status> - <return> - <description>
<return>
can be either a <Schema>
, <Schema[]>/
or a custom JSON {}
@responseHeader (multiple)
Format: <status> - <name> - <description> - <meta>
@paramType
(multiple)
Type
can be one of Parameter Types (first letter in uppercase)
@requestBody (only one) A definition of the expected requestBody
Format: <body>
<body>
can be either a <Schema>
, <Schema[]>/
, or a custom JSON {}
@requestFormDataBody (only one) A definition of the expected requestBody that will be sent with formData format.
Schema
A model or a validator.
Format: <Schema>
Custom format
Format: {"fieldname": {"type":"string", "format": "email"}}
This format should be a valid openapi 3.x json.
🤘Examples
@responseBody
examples
@responseBody <status> - Lorem ipsum Dolor sit amet
@responseBody <status> // returns standard <status> message
@responseBody <status> - <Model> // returns model specification
@responseBody <status> - <Model[]> // returns model-array specification
@responseBody <status> - <Model>.with(relations, property1, property2.relations, property3.subproperty.relations) // returns a model and a defined relation
@responseBody <status> - <Model[]>.with(relations).exclude(property1, property2, property3.subproperty) // returns model specification
@responseBody <status> - <Model[]>.append("some":"valid json") // append additional properties to a Model
@responseBody <status> - <Model[]>.paginated() // helper function to return adonisJS conform structure like {"data": [], "meta": {}}
@responseBody <status> - <Model[]>.paginated(dataName, metaName) // returns a paginated model with custom keys for the data array and meta object, use `.paginated(dataName)` or `.paginated(,metaName)` if you want to override only one. Don't forget the ',' for the second parameter.
@responseBody <status> - <Model>.only(property1, property2) // pick only specific properties
@requestBody <status> <myCustomValidator> // returns a validator object
@responseBody <status> - {"foo": "bar", "baz": "<Model>"} //returns custom json object and also parses the model
@responseBody <status> - ["foo", "bar"] //returns custom json array
@paramPath
and @paramQuery
examples
// basicaly same as @response, just without a status
@paramPath <paramName> - Description - (meta)
@paramQuery <paramName> - Description - (meta)
@paramPath id - The ID of the source - @type(number) @required
@paramPath slug - The ID of the source - @type(string)
@paramQuery q - Search term - @type(string) @required
@paramQuery page - the Page number - @type(number)
@requestBody
examples
// basicaly same as @response, just without a status
@requestBody <Model> // Expects model specification
@requestBody <myCustomValidator> // Expects validator specification
@requestBody <Model>.with(relations) // Expects model and its relations
@requestBody <Model[]>.append("some":"valid json") // append additional properties to a Model
@requestBody {"foo": "bar"} // Expects a specific JSON
@requestFormDataBody
examples
// Providing a raw JSON
@requestFormDataBody {"name":{"type":"string"},"picture":{"type":"string","format":"binary"}} // Expects a valid OpenAPI 3.x JSON
// Providing a Model, and adding additional fields
@requestFormDataBody <Model> // Expects a valid OpenAPI 3.x JSON
@requestFormDataBody <Model>.exclude(property1).append("picture":{"type":"string","format":"binary"}) // Expects a valid OpenAPI 3.x JSON

What does it do?
AutoSwagger tries to extracat as much information as possible to generate swagger-docs for you.
Paths
Automatically generates swagger path-descriptions, based on your application routes. It also detects endpoints, protected by the auth-middlware.
Responses and RequestBody
Generates responses and requestBody based on your simple Controller-Annotation (see Examples)
Schemas
Models
Automatically generates swagger schema-descriptions based on your models
Interfaces
Instead of using param: any
you can now use custom interfaces param: UserDetails
. The interfaces files need to be located at app/Interfaces/
Extend Models
Add additional documentation to your Models properties.
SoftDelete
Either use compose(BaseModel, SoftDeletes)
or add a line @swagger-softdeletes
to your Model.
Attention!
The below comments MUST be placed 1 line above the property.
@no-swagger
Although, autoswagger detects serializeAs: null
fields automatically, and does not show them. You can use @no-swagger for other fields.
@enum(foo, bar) If a field has defined values, you can add them into an enum. This is usesfull for something like a status field.
@format(string) Specify a format for that field, i.e. uuid, email, binary, etc...
@example(foo bar) Use this field to provide own example values for specific fields
@props({"minLength": 10, "foo": "bar"}) Use this field to provide additional properties to a field, like minLength, maxLength, etc. Needs to bee valid JSON.
@required Specify that the field is required
// SomeModel.js
@hasMany(() => ProductView)
// @no-swagger
public views: HasMany<typeof ProductView>
@column()
// @enum(pending, active, deleted)
public status: string
@column()
// @example([email protected])
public email: string
@column()
// @props({"minLength": 10})
public age: number
