Bridge provides several endpoints for performing different kinds of analysis. We will only focus on endpoints that provide JS and TS analysis. The endpoints should, in addition to the standard response (issues, metrics, …), provide additional data representing the AST of the analyzed code. This data can be quite large, so we will not provide them as part of the JSON object, but the response from the server will use HTTP multipart MIME type.

For the purpose of this ticket, we will only implement the additional field in the HTTP response and handling of the HTTP multipart response. The AST can be mocked as a dummy string. The real payload for AST will be implemented in https://sonarsource.atlassian.net/browse/JS-159
