Editing Your SDK Docs

Speakeasy-managed SDKs include a README.md file. By default, the README.md file will contain at least these sections:

  • ## SDK Installation - A installation snippet based on the package name provided in the gen.yaml file.
  • ## SDK Example Usage - An example usage snippet based on the first operation in the OpenAPI document.
  • ## SDK Available Operations - Links to documentation that covers all your SDK's methods.

Here's what it looks like put together

  # github.com/client-sdk
 
  <!-- Start SDK Installation -->
  ## SDK Installation
  ```bash
  go get github.com/client-sdk
  ```
  <!-- End SDK Installation -->
 
  <!-- Start SDK Example Usage -->
  ## SDK Example Usage
  ```go
  package main
 
  import (
      "context"
      "fmt"
      "log"
      "os"
 
      "github.com/client-sdk"
      "github.com/client-sdk/pkg/models/shared"
      "github.com/client-sdk/pkg/models/operations"
  )
 
  func main() {
      ctx := context.Background()
 
      opts := []sdk.SDKOption{
          sdk.WithSecurity(shared.Security{
              APIKey: shared.SchemeAPIKey{
                  APIKey: "YOUR_API_KEY",
              },
          }),
      }
 
      s := sdk.New(opts...)
 
      res, err := s.ListPets(ctx)
      if err != nil {
          log.Fatal(err)
      }
 
      if res.Pets != nil {
          // handle response
      }
  }
  ```
  <!-- End SDK Example Usage -->
 
  <!-- Start SDK Available Operations -->
  ## SDK Available Operations
  * `ListPets` - List all pets
  <!-- End SDK Available Operations -->
  <!-- Placeholder for Future Speakeasy SDK Sections -->

You can enhance your README by making choices about the content by adding additional content before or after any of the three main sections (and their content) above. The generator will not overwrite any content you have added to the README.md file. The generator will automatically keep the content within the walled off sections between the <!-- Start ... --> and <!-- End ... --> comments, but the rest is up to you to maintain.

If you would like to take over management of the automatically generated sections, then you can do the following:

  1. Remove the <!-- Start ... -> section comment.
  2. Find the matching <!-- End ... --> section and change it to <!-- No ... -->, which marks that section as managed by you. (This step is important. If you simply remove the "Start" comment, the section may re-inserted as described below.)
  3. Edit the content that was between those comments as you see fit.

If, at any time, you change your mind and want to go back to having Speakeasy manage a section, you can either delete the <!-- No ... --> comment from the file or you can replace it with <!-- Start ... --><!-- End ... --> and the next generation will insert the Spekeasy-managed content back into your file.

Speakeasy may provide other sections other than those shown above and will add more sections in the future as new features are released or you change the configuration of your SDK via changes to your OpenAPI specification and gen.yaml configuration. These new sections will be inserted above the comment named <!-- Placeholder for Future Speakeasy SDK Sections -->. (This heading will always be present in the file and if you remove it, it will be added again just below the last readme section in the file.) Any missing section will be inserted here during generation, so if you do not want a section inserted, be sure to follow the steps above for converting it to a <!-- No ... --> section rather than removing it entirely.

Usage Examples

Methods

By default, the SDK's README.md will include a usage example from a random operation in the OpenAPI document.

To specify one or more operations to be used as the usage example, you can add the x-speakeasy-usage-example extension to any operation in the OpenAPI document. The usage example's response object handling can also be specified with the extension x-speakeasy-usage-example: true (if the operation has more than one defined response).

For example:

paths:
  /pets:
    get:
      x-speakeasy-usage-example:
        title: List the pets
        description: Now you can get all of the pets that have been added
        position: 2
      summary: List all pets
      operationId: ListPets
      tags:
        - pets
      responses:
        "200":
          description: OK
          content:
            application/json:
              x-speakeasy-usage-example: true
              schema:
                $ref: "#/components/schemas/Pets"
            application/xml:
              schema:
                $ref: "#/components/schemas/Pets"
    put:
      x-speakeasy-usage-example:
        title: Add your pet
        description: First, add your own pet
        position: 1
      summary: Add pet
      operationId: AddPet
      tags:
        - pets
      requestBody:
        content:
          application/json:
            schema:
              $ref: "#/components/schemas/Pets"
      responses:
        "200":
          description: OK
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/Pets"

will result in the following being added to the README.md and USAGE.md:

 
## Add your pet
First, add your own pet
 
```csharp
using PetStore;
using PetStore.Models.Pets;
 
var sdk = new PetstoreSDK();
 
var req = new Pet();
 
var res =  await sdk.Pets.AddPetAsync(req);
```
## List the pets
Now you can get all of the pets that have been added
 
```csharp
using PetStore;
using PetStore.Models.Pets;
 
var sdk = new PetstoreSDK();
var res =  await sdk.Pets.GetPetsAsync();
```

This may be particularly useful for guiding users through a specific set of instructions, or a "getting started" section.

The x-speakeasy-usage-example configuration

KeyDescription
titleThe title-text to be used for the usage example (an empty string indicates no title).
descriptionThe description for the usage example (an empty string indicates no description).
positionUsage examples are sorted lowest-to-highest based on position value. Usage examples that share a position value will be sorted in the order in which they appear in the document.

Values

By default when generating usage examples we will use any example values provided for schemas within your OpenAPI document. If examples aren't present we will try to determine the most relevant example to generate from the format field of a schema or the property name of a schema in an object. For example if the schema has format: email or is within a property called email we will generate a random email address as an example value.

securityschemes

For Security Schemes, the OpenAPI specification doesn't allow specify examples for the values needed to populate the security details when initializing the SDKs. To allow you to provide custom examples for these values, you can add the x-speakeasy-example extension to the Security Scheme in your OpenAPI document. For example:

components:
  securitySchemes:
    apiKey:
      type: apiKey
      name: api_key
      in: header
      x-speakeasy-example: YOUR_API_KEY

x-speakeasy-example just needs to be a string value, and will be used as the example value for the Security Scheme. If the Security Scheme is a basic auth scheme, the example value will be a key/value pair for the username and password split by a ; character. For example: YOUR_USERNAME;YOUR_PASSWORD.

 
## Code Comments
 
The Speakeasy CLI as part of its SDK generation will generate comments for Operations and Models in the generated SDKs. These comments are generated from the OpenAPI specification and are based on the summary/description of the Operations or Schemas. The comments will be generated in the target language's docstring format. For example, in Python the comments will be generated as [PEP 257](https://www.python.org/dev/peps/pep-0257/) compliant docstrings.
 
By default comments will be generated for all Operations and Models. To disable comment generation for your SDK, modify your `gen.yaml` file to disable them like so:
 
```yaml
# ...
generation:
  comments:
    disabled: true

Comments

Operation Comments

Comments for each method in the generated SDK will be generated from the summary/description of the Operation. For example, if you have an Operation like so:

paths:
  /pets:
    get:
      operationId: listPets
      summary: List all pets
      description: Get a list of all pets in the system
      responses:
        "200":
          description: A list of pets
          content:
            application/json:
              schema:
                type: array
                items:
                  $ref: "#/components/schemas/Pet"

The generated SDK will have a method commented like so:

// ListPets - List all pets
// Get a list of all pets in the system
func (s *SDK) ListPets(ctx context.Context) (*operations.ListPetsResponse, error) {
// ...
}

If both the summary and description are present, the summary will be used as the first line of the comment and the description will be used as the second line of the comment. If just the description is present, it will be used as the first line of the comment. If both are present but you would like to omit the description as it might be too verbose, you can use the omitdescriptionifsummarypresent option in your gen.yaml file like so:

# ...
generation:
  comments:
    omitDescriptionIfSummaryPresent: true

Model Comments

Comments for each model in the generated SDK will be generated from the description of the Schema. For example, if you have a Schema like so:

components:
  schemas:
    Pet:
      type: object
      description: A pet sold in the pet store
      properties:
        id:
          type: integer
          format: int64
        name:
          type: string

The generated SDK will have a model commented like so:

// Pet
// A pet sold in the pet store
type Pet struct {
    // ...

Per-SDK Comments

For even greater control, you can configure comments that only show up in the SDK for a single language. If, for example, you need the comment for the TypeScript or Golang SDK to say something different from the others or want to control the documentation separately for each, Speakeasy provides a tool for this purpose via the x-speakeasy-docs extension. Anywhere you can set the summary or description, you can also add x-speakeasy-docs with per-language docs.

Consider the following parameter description:

  parameters:
    - name: type
      in: query
      description: This query parameter names the type of drink to filter the results by. If not provided, all drinks will be returned.
      required: false
      schema:
        $ref: "#/components/schemas/DrinkType"
      x-speakeasy-docs:
        go:
          description: The type field names the type of drink to filter the reuslts by. If set to nil, all drinks will be returned.
        python:
          description: The ``type`` field names the type of drink to filter the results by. If set to ``None``, all drinks will be returned.
        typescript:
          description: This field is the type of drink to filter the results by. If set to null, all drink will be returned.

This will result in the documentation generated for Go, Python, and TypeScript SDKs each being different.

Class Names

By default The Speakeasy SDKs will be generated with the Class Name SDK. However a custom class name can be configured by modifying your gen.yaml file to include:

generation:
  sdkClassName: "myClassName"

Yields a package like:

package petshop
 
import (
	"net/http"
 
	"openapi/pkg/utils"
)
 
var ServerList = []string{
	"http://petstore.speakeasy.io/v1",
}
 
type HTTPClient interface {
	Do(req *http.Request) (*http.Response, error)
}
 
type PetShop struct {
	Pets *Pets
 
	_defaultClient  HTTPClient
	_securityClient HTTPClient
 
	_serverURL  string
	_language   string
	_sdkVersion string
	_genVersion string
}
