0.31.0

(feat): Add omitUndefined generator option. This is enabled with the following config:

1
groups:
2
  generators:
3
    - name: fernapi/fern-typscript-node-sdk
4
      version: 0.31.0
5
      ...
6
      config:
7
        omitUndefined: true

When enabled, any property set to an explicit undefined is not included in the serialized result. For example,

1
const request: Acme.CreateUserRequest = {
2
  firstName: "John",
3
  lastName: "Doe",
4
  email: undefined
5
};

By default, explicit undefined values are serialized as null like so:

1
{
2
  "firstName": "John",
3
  "lastName": "Doe",
4
  "email": null
5
}

When omitUndefined is enabled, the JSON object is instead serialized as:

1
{
2
  "firstName": "John",
3
  "lastName": "Doe"
4
}
