Create File with Google Drive Api v3 (javascript)

Question

I want to create a file with content using Google Drive API v3. I have authenticated via OAuth and have the Drive API loaded. Statements like the following work (but produce a file without content):

gapi.client.drive.files.create({
    "name": "settings",
}).execute();

Unfortunately I cannot figure out how to create a file that has a content. I cannot find a JavaScript example using Drive API v3. Are there some special parameters that I need to pass?

For simplicity, assume that I have a String like '{"name":"test"}' that is in JSON format that should be the content of the created file.

Unfortunately, I have not found an answer using only the google drive api, instead I followed Gerardo's comment and used the google request api. Below is a function that uploads a file to google drive.

var createFileWithJSONContent = function(name,data,callback) {
  const boundary = '-------314159265358979323846';
  const delimiter = "\r\n--" + boundary + "\r\n";
  const close_delim = "\r\n--" + boundary + "--";

  const contentType = 'application/json';

  var metadata = {
      'name': name,
      'mimeType': contentType
    };

    var multipartRequestBody =
        delimiter +
        'Content-Type: application/json\r\n\r\n' +
        JSON.stringify(metadata) +
        delimiter +
        'Content-Type: ' + contentType + '\r\n\r\n' +
        data +
        close_delim;

    var request = gapi.client.request({
        'path': '/upload/drive/v3/files',
        'method': 'POST',
        'params': {'uploadType': 'multipart'},
        'headers': {
          'Content-Type': 'multipart/related; boundary="' + boundary + '"'
        },
        'body': multipartRequestBody});
    if (!callback) {
      callback = function(file) {
        console.log(file)
      };
    }
    request.execute(callback);
}
