Publishing to RubyGems

Configure output location

Next, change the output location in generators.yml from local-file-system (the default) to pypi to indicate that Fern should publish your package directly to the PyPI registry:

1
groups: 
2
  ruby-sdk:
3
    generators:
4
      - name: fernapi/fern-ruby-sdk
5
        version: 1.12.1
6
        output:
7
          location: rubygems

Add a unique package name

Your package name must be unique in the RubyGems repository, otherwise publishing your SDK to RubyGems will fail. Update your package name if you haven’t done so already:

1
groups: 
2
  ruby-sdk:
3
    generators:
4
      - name: fernapi/fern-ruby-sdk
5
        version: 1.12.1
6
        output:
7
          location: rubygems
8
          package-name: your-package-name

Configure clientModuleName

The clientModuleName option controls the name of the generated client. This is the name customers use to import your SDK (import { your-client-name } from 'your-package-name';).

groups: 
2
  ruby-sdk:
3
    generators:
4
      - name: fernapi/fern-ruby-sdk
5
        version: 1.12.1
6
        output:
7
          location: rubygems
8
          package-name: your-package-name
9
        config:
10
          clientModuleName: YourClientName # must be PascalCase

Add repository location

Add the path to your GitHub repository to generators.yml:

1
groups: 
2
  ruby-sdk:
3
    generators:
4
      - name: fernapi/fern-ruby-sdk
5
        version: 1.12.1
6
        output:
7
          location: rubygems
8
          package-name: your-package-name
9
        config:
10
          clientModuleName: YourClientName
11
        github: 
12
          repository: your-org/company-ruby

Log into RubyGems

Log into RubyGems or create a new account.

Navigate to Account settings

1. Click on your profile picture
2. Select Settings.
3. Scroll down and click on API Keys.

Add New Key

When prompted to create a new API key:

1. Name your key.
2. Under Scopes, select Push rubygem
3. Select All Gems under Gem Scope.

1. Set an expiration date.
2. Click Create API Key.

Configure RubyGems authentication token

Add api-key: ${RUBYGEMS_API_KEY} to generators.yml to tell Fern to use the RUBYGEMS_API_KEY environment variable for authentication when publishing to the PyPI registry.

    generators:

      - name: fernapi/fern-ruby-sdk
5
        version: 1.12.1
6
        output:
7
          location: rubygems
8
          package-name: your-package-name
9
          api-key: ${RUBYGEMS_API_KEY}
10
        config:
11
          clientModuleName: YourClientName
12
        github: 
13
          repository: your-org/company-ruby

Set RubyGems environment variable

On your local machine, set the RUBYGEMS_API_KEY environment variable to the new API key you generated earlier:

$
export RUBYGEMS_API_KEY=your-actual-rubygems-token

Generate your release

Regenerate your SDK and publish it on RubyGems:

$
fern generate --group ruby-sdk --version <version>

Local machine output will verify that the release is pushed to your repository and tagged with the version you specified. Log back into RubyGems and navigate to Releases to see your new release.
