Add support for ESLint doc url meta, update dependencies, support TypeScript 2.7 #84

kaelig · 2018-03-13T23:59:09Z

Released under version 20.0.0.

Breaking: the version of TypeScript supported by this plugin is 2.7.x (in line with typescript-eslint-parser’s TypeScript support)
Updated dependencies that support the new ESLint documentation URL metadata. Errors from these plugins are accompanied by a link to the documentation for the broken rule.
Updated various other dependencies to their latest versions
Dependencies are now strictly versioned for tighter control over the exact rules the plugin enforces.

Package	old	new
`eslint-plugin-ava`	`^4.4.0`	`4.5.1`
`eslint-plugin-import`	`^2.8.0`	`2.9.0`
`eslint-plugin-jest`	`^21.5.0`	`21.14.1`
`eslint-plugin-lodash`	`^2.5.0`	`2.6.1`
`eslint-plugin-node`	`^5.2.1`	`6.0.1`
`eslint-plugin-prettier`	`^2.4.0`	`2.6.0`
`eslint-plugin-promise`	`^3.6.0`	`3.7.0`
`eslint-plugin-react`	`^7.5.1`	`7.7.0`
`eslint-plugin-typescript`	`^0.8.1`	`0.10.0`

Added rules:
- react/forbid-dom-props (disabled)
- react/jsx-child-element-spacing error
- react/jsx-max-depth (disabled)
- react/jsx-sort-default-props (disabled)
- react/no-this-in-sfc error
- import/group-exports (disabled)
- import/no-self-import error
- import/no-default-export (disabled)
- import/no-useless-path-segments error
- jest/prefer-expect-assertions (disabled)
- jest/valid-expect-in-promise error
- jest/valid-describe error
- jest/consistent-test-it error
- jest/no-test-prefixes error
- jest/lowercase-name error
- jest/no-jest-import error
- promise/valid-params error
- promise/no-new-statics (disabled)
- typescript/explicit-function-return-type (disabled)
- typescript/no-non-null-assertion error
Updated import/extensions due to changes in its implementation: some extensions are explicitly allowed in imports: .svg, .png, .jpg, .ico. .json is still required as well.
Chore: updated CircleCI from v1 to v2

`jest/lowercase-name`

I believe @lemonmade likes having tests that start with lowercase, so I turned on the new rule jest/lowercase-name, however it fails on this type of code:

describes should begin with lowercase

describe('ModuleConcatenationPlugin', () => {

Should I turn jest/lowercase-name back off?

`jest/valid-describe`

Fails on this code from sewing-kit:

No async describe callback

  describe('cache', async () => {
    it('always sets cacheing to true', async () => {
      expect(
        await webpackConfig(createWorkspace({env: client})),
      ).toHaveProperty('cache', true);
      expect(
        await webpackConfig(createWorkspace({env: server})),
      ).toHaveProperty('cache', true);
    });
  });

@GoodForOneFare any thoughts? Are async callbacks generally to be avoided or should we allow it?

`jest/consistent-test-it`

Fails on this code from sewing-kit:

Prefer using 'test' instead of 'it'

it('fails', () => {
  expect(true).toBe(false);
});

By default, the rule enforces test at the root of test files, and it when nested under describe.

Thoughts?

cartogram · 2018-03-14T07:13:26Z

Personally, I would prefer the jest/lowercase-name only be enforced on it and not describe (jest-community/eslint-plugin-jest#92). My guess is that would remove most of the failures.

lemonmade

This is great! Do we have to do something to have our own rules support he new doc links thing?

I think you are missing a rule (the above us not the correct description for the rule)

Also, this rule should definitely be on, it’s a very common problem

Good catch, it was missing https://github.com/jest-community/eslint-plugin-jest/blob/master/docs/rules/prefer-expect-assertions.md

I think we’d want this rule on as well

If Prettier already takes care of this for devs, I’m not sure this needs to be turned on

I don't know if Prettier would take care of this? It's more of a clarification mechanism for developers, and in any case, Prettier is not necessarily being used when using this particular set of rules (if it does conflict with Prettier, we can turn it off just for the prettier config)

Oh you're right, I was thinking of another rule that had to do with styles and has almost the same name. Turned on in 9978763

lemonmade · 2018-03-14T12:24:27Z

All the Jest rules are good but I think we need to disable the lowercase one for now until we can turn it off for describe, as we recommend using the full component/ class name there where appropriate.

kaelig · 2018-03-14T16:47:23Z

Thank you for the feedback!

Recap of the changes:

Allow graphql, css, sass, scss, less, styl file extensions in imports
Turn rule jest/valid-expect-in-promise on
Turn rule react/no-this-in-sfc on
Turn rule react/jsx-child-element-spacing on
Turn rule jest/lowercase-name off (for now)

How do we feel about this rule https://github.com/jest-community/eslint-plugin-jest/blob/master/docs/rules/consistent-test-it.md?

This is great! Do we have to do something to have our own rules support he new doc links thing?

Yes we do. I'm opening a new branch for that.

ismail-syed · 2018-03-14T17:38:10Z

When I wrote jest/lowercase-name , I originally had it to only flag it descriptions. The maintainers suggested enforcing describe and test. jest-community/eslint-plugin-jest#56 (comment).

Glad to see there's an open PR for adding ignore options

kaelig · 2018-03-14T21:52:32Z

Just published: 20.0.0-beta.4 🚢

@lemonmade react/jsx-child-element-spacing conflicts with prettier:

Replace {'·'} with · (prettier/prettier)

Ambiguous spacing after previous element span

I agree this is a useful rule, any suggestions on how to deal with it?

Edit: found a workaround:

                <span className={styles.HeaderTextShopify}>Shopify</span>{' '}
                Polaris

lemonmade · 2018-03-15T14:51:21Z

I still might be misunderstanding the rule, but I don't think they conflict. The biggest overlap is that Prettier might sometimes change code that this rule would flag to not require the explicit space at all (example from the rule):

<div>
  Here is a
  <a>link</a>
</div>

// becomes with Prettier:
<div>Here is a  <a>link</a></div>

// which is acceptable for this rule, which deals only with newline-separate siblings I think

I confirmed that Prettier does not try to correct the case where you make explicitly no space between newline-separate children. I think we are fine to leave this on, and it just kind of works in tandem with the Prettier formatting.

kaelig · 2018-03-15T23:56:36Z

Thanks, I guess I was a bit confused because you can't add a trailing space into an element (<Foo>foo </Foo> makes ESLint and Prettier conflict) but it's so rarely a thing that I don't think it's an issue.

Let's ship it!
