Alphabetize imports within groups #1105

duncanbeevers · 2018-05-17T23:48:03Z

In order to provide absolute ordering, rather than just group-wise ordering, this PR offers an alphabetize option that enforces locale-aware alphabetical intra-group ordering.

It makes no effort to provide a more robust fix experience, so multiple passes may be necessary to bring a set of imports into a stable configuration, though since an absolute ordering is available, a single-pass fix probably isn't unreasonable.

Fixes #1406.

I think it's pretty important to try to avoid multiple passes.

+By default, no ordering within groups is enforced. When `alphabetize: true` is used, imports must be alphabetically ordered within their groups.


This seems a bit restrictive; will people always want a-z? what about z-a? What about capital letters? Should it be a, A, b, c, D, or A, a, b, c, D, or a, b, c, A, D?

Great questions. When I took a run at this in the past, I got some pushback around finding a balance between flexibility and simplicity.

Today's approach was more conservative, and the results aren't perfect. For example, we'd love to be able to differentiate webpack aliases from external node modules, and to sort asset-type resources such as .css separately from ordinary modules.

will people always want a-z? what about z-a?

People don't seem to care much about absolute ordering at all today; I'd be a little bit surprised if many people wanted z-a. My real fear is people wanting an arbitrary comparator. It's not difficult to add, but it's difficult to express declaratively, like in an .eslintrc.json file.

Basically, I want a completely stable sort, and alphabetical is pretty politically-neutral.

What about capital letters?

localeCompare accepts some options that it would be straightforward to thread through declaratively from the eslint config, if that's something users want.

Basically, I want a completely stable sort, and alphabetical is pretty politically-neutral.

I, as a person who's interested in using this lint, second this.

@ljharb what's your thought on @duncanbeevers response to your comment here? I am thinking a-z ordering should be good enough for majority of users.

I think a-z and z-a is a minimum, as well as an option that chooses between “z comes before/after A” and “z is right next to Z”. I definitely don’t want an arbitrary comparator.

duncanbeevers · 2018-05-22T19:33:37Z

We ended up writing a custom eslint plugin that we could tune to support our specific ordering rules. I closed this issue since I no longer need the functionality myself.

If someone wants to take this to completion feel free, but I'm setting it aside.

robwierzbowski · 2019-01-08T15:36:24Z

@duncanbeevers Can you show your custom plugin in a gist?

Recently my team has run into the shared chunk warning in the mini-css-extract-plugin documented here:

webpack-contrib/mini-css-extract-plugin#246
webpack-contrib/mini-css-extract-plugin#250

Alphabetizing and grouping (creating a deterministic, consistent order of imports across modules) may fix the shared chunk CSS import problem. Interested in this PR, and might be interested in contributing if my company will give me time to.

I second the motion. 😄

@ljharb Hi, I am interested to use the ordering here. Do you think @duncanbeevers 's PR is close to completion? What else would be necessary in order to get this PR merged? I probably can help if anyone can give me a direction

ljharb · 2019-01-31T15:41:34Z

@dannysindra there’s a few open comments; it needs a rebase.

If you’d like to help, please don’t open another PR, but please do post a link to your branch here (with these rebased commits, and any new ones) and I’ll be happy to update the PR with them. Thanks!

dannysindra · 2019-02-04T04:12:01Z

@ljharb I finished making the changes in my repo: https://github.com/dannysindra/eslint-plugin-import/tree/alphabetize.

So I made the following configs for the alphabetize option:

order: [string] - either ignore (do not use alphabetize), asc, or desc
ignoreCase: [boolean] - if false put upper before lowercase (normal js sort), if true put upper and lowercase together (localeCompare)

Please let me know if you have any feedback / questions. This is my first contribution btw, so I apologize in advance if I made beginner mistakes here and there

ljharb · 2019-02-04T06:28:42Z

@dannysindra i was hoping for a rebase, not a merge (no merge commits) but i've gone ahead and updated this branch with a rebased version of its, and your, commits. I'll give it a review once tests are passing.

dannysindra · 2019-02-04T08:03:42Z

@ljharb thanks for the quick response! My bad, I tried to rebase and somehow must have pulled and merged. I am trying to understand what causes the tests to fail here.. it passes locally and on some env in the AppVeyor; but failed on others? Also, is there a way to run the coveralls locally? I cannot tell which lines / files decreased the coverage..

ljharb · 2019-02-04T08:07:46Z

@dannysindra make sure you're checking out the rebased version; the travis tests are failing too.

dannysindra · 2019-02-04T09:00:14Z

@ljharb alright, I have rebased, and pushed again with the fix 7fa20f0

ljharb · 2019-02-04T23:03:51Z

@dannysindra thanks, updated (next time, please delete your local branch, and re-check it out from 3db6bd7)

VincentLanglet · 2019-04-19T14:25:08Z

@dannysindra There are conflicts, so you can start by rebasing the branch.
The tests will re-run with the new push.

ljharb · 2019-05-05T20:51:17Z

This still needs a rebase.

kg-currenxie · 2019-05-07T09:26:29Z

Well obviously it wasn't only about rebasing the existing code :-D I'm willing to do max. 1 more change. So please, if you have any more suggestions for improvement, give it all to me at once

+```js
+import foo from 'foo';
+import bar from 'bar';
+import Baz from 'Baz';


These examples make it unclear whether the sorting happens by module names or by bindings names. Making them different would help (this applies to all new examples in this file).

And here I though the code is all good and I just need to rebase it.
Totally agree with you about this one

Good to hear. Right now, it's in a state of waiting for the maintainers to express themselves - and possibly merge it #1360
