use multi-threaded flask dev server to prevent HTTP requests from hanging in Chrome (!92) · Merge requests · DSA San Francisco / membership_api

Jesse Young requested to merge flask-threaded into dev Jan 27, 2018

Chrome opens a TCP connection to the API server without making a HTTP request, which causes other API requests to hang for a varying amount of time because the flask dev server is single-threaded by default. A workaround is to use threaded=True to make the flask dev server multi-threaded.
