Orchestrate Multi Target Sdks

Orchestrate Multi-Target SDKs

Generate SDKs for multiple languages or variants from a single repository using CLI commands.

When to Use

• Generating SDKs for multiple languages from the same API spec
• Creating SDK variants (Azure, GCP, regional) from different specs
• Setting up an SDK monorepo
• User says: "generate SDKs for multiple languages", "SDK for each language", "multi-target"

Quick Start: Multiple Languages

Always use CLI commands. Never create .speakeasy directories manually.

# Step 1: Initialize first target (creates .speakeasy/workflow.yaml)
speakeasy quickstart --skip-interactive --output console \
  -s openapi.yaml -t typescript -n "MySDK" -p "my-sdk"

# Step 2: Add more language targets using configure
speakeasy configure targets \
  --target-type python \
  --source my-source \
  --output ./sdks/python

speakeasy configure targets \
  --target-type go \
  --source my-source \
  --output ./sdks/go

# Step 3: Generate all SDKs
speakeasy run --output console

CLI Reference

speakeasy configure sources

Add a new OpenAPI source to an existing workflow:

speakeasy configure sources \
  --location ./openapi.yaml \
  --source-name my-api

# With authentication header
speakeasy configure sources \
  --location https://api.example.com/openapi.yaml \
  --source-name my-api \
  --auth-header "Authorization"

| Flag | Short | Description | |------|-------|-------------| | --location | -l | OpenAPI document location (file or URL) | | --source-name | -s | Name for the source | | --auth-header | | Authentication header name (optional) | | --output | -o | Output path for compiled source (optional) | | --non-interactive | | Force non-interactive mode |

speakeasy configure targets

Add a new SDK target to an existing workflow:

speakeasy configure targets \
  --target-type typescript \
  --source my-api \
  --output ./sdks/typescript

# With all options
speakeasy configure targets \
  --target-type go \
  --source my-api \
  --target-name my-go-sdk \
  --sdk-class-name MyAPI \
  --package-name github.com/myorg/myapi-go \
  --output ./sdks/go

| Flag | Short | Description | |------|-------|-------------| | --target-type | -t | Language: typescript, python, go, java, csharp, php, ruby, terraform | | --source | -s | Name of source to generate from | | --target-name | | Name for the target (defaults to target-type) | | --sdk-class-name | | SDK class name (optional) | | --package-name | | Package name (optional) | | --base-server-url | | Base server URL (optional) | | --output | -o | Output directory (optional) | | --non-interactive | | Force non-interactive mode |

Example: Multi-Language SDKs

Single OpenAPI spec → TypeScript, Python, Go SDKs:

# Initialize with first target
speakeasy quickstart --skip-interactive --output console \
  -s ./openapi.yaml -t typescript -n "MySDK" -p "my-sdk" -o ./sdks/typescript

# Add Python
speakeasy configure targets \
  --target-type python \
  --source my-source \
  --sdk-class-name MySDK \
  --package-name my-sdk \
  --output ./sdks/python

# Add Go
speakeasy configure targets \
  --target-type go \
  --source my-source \
  --sdk-class-name MySDK \
  --package-name github.com/myorg/my-sdk-go \
  --output ./sdks/go

# Generate all
speakeasy run --output console

Example: SDK Variants (Multiple Sources)

Different OpenAPI specs → variant SDKs:

# Initialize with main API
speakeasy quickstart --skip-interactive --output console \
  -s ./openapi.yaml -t typescript -n "MySDK" -p "my-sdk"

# Add Azure variant source
speakeasy configure sources \
  --location ./openapi-azure.yaml \
  --source-name azure-api

# Add Azure target
speakeasy configure targets \
  --target-type typescript \
  --source azure-api \
  --target-name typescript-azure \
  --sdk-class-name MySDKAzure \
  --package-name "@myorg/my-sdk-azure" \
  --output ./packages/azure

# Generate all
speakeasy run --output console

Running Generation

# Generate all targets
speakeasy run --output console

# Generate specific target only
speakeasy run -t typescript --output console
speakeasy run -t python --output console

CI Workflow

  push:
    branches: [main]
    paths: ['openapi.yaml']
  workflow_dispatch:

What NOT to Do

• Do NOT create .speakeasy/ directories manually - Use speakeasy quickstart and speakeasy configure
• Do NOT write workflow.yaml or gen.yaml files directly - Use CLI commands
• Do NOT copy .speakeasy/ directories between projects - Each needs its own config

Incorrect

# WRONG: Do not do this
mkdir -p .speakeasy
cat > .speakeasy/workflow.yaml  **Configuration complete.** Would you like to regenerate the SDK(s) now with `speakeasy run`?

If the user confirms, run:

```bash
# Generate all targets
speakeasy run --output console

# Or generate a specific target
speakeasy run -t  --output console

Changes to workflow.yaml and gen.yaml only take effect after regeneration.
