npm outdated only shows packages that have newer versions available, independent of their deprecation status. Thus, it does not show deprecated packages that won't get updates anymore (e.g. request or @hapi/joi).

If you use npm version 7 or newer, you should have a package-lock.json with lockfileVersion: 2. This lockfile contains the deprecation warnings of all installed packages.

You can use jq to find all packages that have deprecation warnings:

jq -r '.packages | to_entries[] | select(.value.deprecated != null) | "\(.key):\n\(.value.deprecated)\n"' package-lock.json

The output will look like this:

node_modules/har-validator:
this library is no longer supported

node_modules/request:
request has been deprecated, see https://github.com/request/request/issues/3142

node_modules/request-oauth/node_modules/uuid:
Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.

Open your terminal and run these two commands:

  1. cd
  2. npm outdated

It should return a list of outdated packages that need to be upgraded.
