The directory also contains a package.json file specifying that the directory contains commonjs modules. They are copied here in order to prevent direct requires from /src, which could make migrating the src to ES modules troublesome.
JEST CLEAR MOCKS CODE
In general server refers to the version of the source code designed for running in nodejs, whereas client refers to the version designed to run in the browser. The following detail may help debug any problems, and a few known workarounds are listed below.
