Yo should use esm

[Logicer16]

Type of issue

Bug Report

---

My environment

• OS version/details: macOS Monterey 12.6.7
• Node version: v20.2.0 (run node --version in your terminal)
• npm version: 9.6.6 (run npm --version in your terminal)
• Version of yo : 4.3.1 (run yo --version in your terminal)

Expected behavior

yo has no vulnerable dependancies.

Current behavior

The following are vulnerable package versions from yo and its dependancies, yeoman/doctor and yeoman/insight:

meow: < v6.0.0
bin-version-check: < v5.0.0
got: < v12.0.0
npm-keyword: < v7.0.0
update-notifier: < v6.0.0
latest-version: < v6.0.0

However these packages are now all pure esm.
To allow for these dependancies to be updated, and thus for the vulnerabilities to be fixed, yo, yoeman/doctor, and yeoman/insight should switch to esm as well.

This has additionally caused problems with insight as os-name >= v5.0.0 is also pure esm, which resulted in insight being removed.

This has been an ongoing issue for the project. Related issues I've found include (17 total):

• yo depends on deprecated module.parent, should update meow #786
• Vulnerability in dependency for Yo #780
• Bump got from 8.3.2 to 12.5.3 #773
• Bump meow from 5.0.0 to 11.0.0 #766
• Unable to run yo on macOS Ventura Beta #753
• Bump npm-keyword from 6.1.0 to 7.0.0 #751
• Bump update-notifier from 5.1.0 to 6.0.2 #749
• 15 vulnerabilities when installing #716
• Update vulnerable dependencies trim-newlines and glob-parent #679
• Can't run yo on macos monterey #683
• Support macOS 13 Ventura insight#83
• update os-name  insight#82
• Error in macOS venture insight#81
• Support macOS 13 Ventura insight#80
• Any one could share insight roadmap ? (for macos monterey ) insight#78
• Consider using got over request. insight#52
• chore: update bin-version-check doctor#58

Each of these require this being implemented to be properly fixed.

Other yeoman packages have already made the switch to esm, including update-notifier, stringily-object, and configstore, with environment and generator soon to follow.

[IrrerPolterer]

Is there any progress towards fixinv the vulnerable dependencies? Trying to install yo at the moment fires a ton of vulnerability warnings. In this state yo is unusable for our purposes.

[mshima]

yeoman-generator, yeoman-environment and yeoman-test are ESM now.

Help is wanted to migrate yo to ESM.
In the mean time, yeoman-environment is been dynamic loaded to workaround requiring an ESM module.
