NPM dependencies out of date

[adams-family]

Hi,

Jusrt a small note: I think that the package.json file will need an update because the current version throws a lot of high severity and critical vulnerabilities:

added 145 packages from 433 contributors and audited 270 packages in 7.894s
found 11 vulnerabilities (3 low, 2 moderate, 5 high, 1 critical)
run npm audit fix to fix them, or npm audit for details
