Should we use Prettier?

[segayuu]

eslint has nearly 90 rules even for category Stylistic Issues alone.
It is very difficult to handle all these correctly.

Because eslint understands that, if you activate only recommended settings, required items in most projects will be set. However, Stylistic Issues often depends on individuality, the recommended config is no-mixed-spaces-and-tabs only.

By using Prettier it is certain that almost all of those settings will be unified.
However, that is a tradeoff with fewer things we can explicitly control.
In fact, the multi-line option of the curly rule will be disabled with Prettier!

I talked a little while ago about this issue.
hexojs/hexo#2846

I prefer to take a full prettier format on the existing code.

However, it is pretty tedious and error-prone to add different versions of prettier/husky/lint-staged to the existing projects. Actually we have suffered from outdated eslint config on less frequently updated package.

It comes to me that lerna can reduce these maintenance nightmare if we switch to monorepo so that all hexo packages shares eslint/babel/prettier/lint-staged settings.

If you do monorepo and organize the registry, you should also consider using npm scoped package.
I think that should not be done at the same time.

When doing them, at least we should inform this to all Hexo maintainers.

[JLHwung]

The npm scoped package is definitely nice to have but it is breaking change for users. As we have separated hexo packages in the very early days, from the users perspective, it is not persuading to change hexo-* to @hexo/* without a stronger reason, like performance boost/less bugs/major rewrite.

Additionally, the monorepo and scoped npm package is independent.

When doing them, at least we should inform this to all Hexo maintainers.

Good idea, could you raise a discussion on the main repo?

[segayuu]

ok, For each member of @hexojs/core, we set up a discussion thread.

It can be quite a nice move to find the right setup of prettier on this repo first before even trying to scale it to a larger amount of repos.

Prettier has some nice commits hooks where it can only be applied to changed lines.

That can be replicated bit by bit to other repos and see how much pain/benefits it generates before thinking to move to monorepo (this brings its own bagage of discussions/painpoints without solving the prettier problem).

[segayuu]

@oncletom Is the hook you are talking about precise-commits? (Since there are multiple hooks, I will confirm it just in case.)

[thom4parisot]

@segayuu yes exactly. I have tried this one and the plain git command.

But the latter is not cross-compatible between OSes.

Yes please use prettier 👍

I don't have any strong opinion about the actual linter, as long as the style used is uniform across the project. (You can keep eslint or switch to prettier, as long as the same rules are enforce everywhere).

I'm not comfortable with lerna and monorepos for JS (seems to be at odds with Node's way of doing things). To help with maintaining dependencies up to date, you can look into integrating "Greenkeeper". I'm only an occasional maintainer so I have no strong opinions on this either.
