Martin Splitt from Google announced while at Google I/O yesterday that they have updated the Google Code lab not to just support structured data but also single page apps (SPAs) and dynamic rendering. Code lab is a solution that walks you through step-by-step to create either structured data, SPAs or dynamic rendering that works with Google search. Note, Google launched the code lab last year in August 2018 to support structured data only.
