Requirements

• Node 18 or higher
• A GitHub account
• The Fern GitHub App installed

Step 1: Use this template

1. Click on the Use this template button (found at the top right of this page). You must be logged into GitHub.
2. Choose the option to create a new repository. Name it whatever you'd like.

Step 2: Clone and configure the repo

1. Clone your newly created repository and open it in your favorite code editor (e.g., VS Code).
2. Open fern.config.json and update the organization field with your organization name.

{
  "organization": "your-organization-name",
  "version": "0.65.32"
}

Step 3: Install and configure Fern

1. Install the Fern CLI globally:

npm install -g fern-api

2. Log in to Fern:

fern login

Step 4: Configure your SDK settings

The repository comes pre-configured for TypeScript and Python SDK generation in generators.yml. You'll need to:

1. Create a GitHub repository for each SDK you want to generate
2. Install the Fern GitHub App in your target repository.
3. Uncomment and update the GitHub section in generators.yml with your repository information:

# For Python SDK
github:
  repository: your-org/your-python-sdk-repo

# For TypeScript SDK
github:
  repository: your-org/your-typescript-sdk-repo

Step 5: Generate your SDKs

To generate and publish your SDKs:

fern generate --group python-sdk

AND

fern generate --group ts-sdk

The generated SDKs will be:

• Committed to your specified GitHub repositories
• Published to npm (TypeScript) and PyPI (Python) if configured
• Version-controlled using semantic versioning

Customization Options

The starter comes with some pre-configured options in generators.yml:

You can modify these configurations or add additional options by editing generators.yml.
