After thinking on it for a while, I think undefined should be a legal value for default, and should be treated exactly like default being missing. (So, in particular, setting default: undefined should not cause the key to appear in the values object.) cc @shadowspawn since you expressed the opposite opinion above. Specifically, accepting undefined makes it easier to do stuff like let options = { endpoint: { type: 'string', default: process.env.MY_PROJECT_ENDPOINT } };
let { values } = parseArgs({ options });which is a convenient pattern, especially since this utility almost certainly doesn't want to handle this sort of default-to-env behavior itself. If undefined isn't allowed, then you would have to write something like let options = { endpoint: { type: 'string' } };
if (process.env.MY_PROJECT_ENDPOINT != null) {
opts.endpoint.default = process.env.MY_PROJECT_ENDPOINT;
}
let { values } = parseArgs({ options });which is much less pleasant all around. |

Does this have the same semantics as destructuring with defaults? let { values: { foo = 'default' } } = util.parseArgs({ options: { foo: { type: 'string' } } }) |
Sorry, something went wrong.
The env use case seems pretty reasonable and convenient. I like it.
My comment was in context of the commented code, that I didn't see a need to treat undefined as a valid value for output values. So not in opposition to your suggestion that is useful to allow for input config. |

Fair usage, I will update this PR 👍🏽
Yes, it does. Doing so would be like moving the "default burden logic" to the caller instead of callee, and this is unwanted in my opinion. |

This PR has landed in v18.11.0 parseArgs has also been included in Node.js v16. Is there any additional work require to land this PR in v16, so default is also available there, or will it happen automatically? |
Sorry, something went wrong.
|
Node.js 16.x is going into maintenance mode next tuesday (see https://github.com/nodejs/Release#release-schedule), and there are no scheduled release until then, so PRs won't be "automatically" backported anymore. That means someone would need to open a backport PR for this to land on v16.x. |
Sorry, something went wrong.
|
Thanks for info @aduh95 Light question: might adding default support be acceptable as a back port at this late stage? (i.e. v16.x not in maintenance mode yet, but will be very soon!) |
Sorry, something went wrong.
|
It should be, as long as someone opens a backport PR, see https://github.com/nodejs/node/blob/0f9087971c085ea0c93b9fd867e442afe11c0ae0/doc/contributing/backporting-to-release-lines.md for more info. |
Sorry, something went wrong.
|
There doesn't have to be a backport PR. Another option (especially if the commit can be cherry-picked without conflicts) is to add the lts-watch-v16.x label. |
