How to set cookies with digitalocean functions?

You can set headers in the HTTP responses sent using what your function returned by making sure the dictionary returned by your function includes a headers key.

Example:

def main():
  return {
    'headers': {
      'Set-Cookie': '<header_value>'
    }
  }

Because this example was for Python, a dict is returned. But, this concept applies to all languages supported by Functions. You’d use whichever data type is most appropriate.

Example for Node.js:

function main() {
  return {
    headers: {
      'Set-Cookie': '<header_value>'
    }
  };
}
