[MikeMcC399]

What would you like?

Drop support for Node.js

• ^14.18.0
• ^16.0.0
• <18.18.0

according to the definitions in

eslint-doc-generator/package.json

Lines 90 to 92 in 30abb4b

	"engines": {
	"node": "^14.18.0 || ^16.0.0 || >=18.0.0"
	},

Why is this needed?

The lowest currently supported version of ESLint is v9. The blog for ESLint v9.0.0 states that a minimum Node.js v18.18.0 is required.

According to Node.js Release schedule:

• Node.js 14.x entered end-of-life on Apr 30, 2023
• Node.js 16.x entered end-of-life on Sep 11, 2023

Node.js currently supports:

• Node.js 18.x (Maintenance LTS)
• Node.js 20.x (Maintenance LTS)
• Node.js 22.x (Active LTS)
• Node.js 23.x (Current)

In order to allow migration of devDependencies to proceed, the workflow .github/workflows/ci.yml already dropped Node.js 14.x and 16.x from CI tests in PR #536.

Other

• Updating the minimum version of Node.js is a breaking change (also according to the comments in the README > Semantic versioning policy).

• Consideration should be given to delaying this change until Support ESLint v9 #526 is resolved and possibly releasing a new major version which raises the minimum Node.js and ESLint versions at the same time.
