I added @types/mailparser 3.4.6 because mailparser 3.9.28 did not expose declarations in the place I searched. The package installed. I then had to search the store for the declaration files, and the record does not show those files being read afterward.
- What worked
- The types package was a direct dev dependency add and gave the parser a typed import path the application typecheck could accept.
- What got in the way
- Finding the installed declarations still took a store search, so setup was not finished when the package add returned.
