Jakob Guddas

@jguddas

are there rules for

x = [
  {
    ...
  },
  {
    ...
  }
]

to be

x = [ {
  ...
}, {
  ...
}]

Hi All!
I have a question about the EsLint with SonarQube. I checked the EsLint webpage and Google, but i did not found valuable answer for it.
We use our own collections of the javascript rules in a SonarQube server and it connected to our VSCode via SonarLint. Can we replace it with EsLint? Do you have any solution to use the rules from the server(connect server, download rules, use)?

Kai Cataldo

@kaicataldo

Hey there, I don’t know anything about SonarLint, but ESLint is pluggable and has a Node API that you might be able to integrate with a script you write.

Documentation can be found here: https://eslint.org/docs/developer-guide/nodejs-api

hi guys can help me with this error? eslint-plugin-prettier not working correctly i cant see any warning and fix eslint problems

Roy Sutton

@webOS101

Does it work if you run eslint from the terminal?

Marco Gutierrez

@marcosguti

example: eslint --fix actionReducer/index.js works but file view in vs-code dont show any warnings and fix suggestion when have errors

Roy Sutton

@webOS101

I think vscode is not setting the correct working directory for linting.

Marco Gutierrez

@marcosguti

not sure i think its really weird

maybe i should remove vs-code and install again?

Roy Sutton

@webOS101

Is the root of your workspace the same as the root directory you’re linting?

Marco Gutierrez

@marcosguti

how i can check that?

BrianD91

@BrianD91

how can I do conditionals in eslint?

Like if I use a certain import statement in my code, then I need to be sure that at the top of the file there's a /** @jsx jsx */ pragma

Marco Gutierrez

@marcosguti

@webOS101 ?

Roy Sutton

@webOS101

When you go to the file list in VS Code, is api the root?

Marco Gutierrez

@marcosguti

yes

Roy Sutton

@webOS101

Then I don’t know. I don’t have VS Code set up the same way so I can’t help debug that.

Hello, is there anyone online here?

@raghukiranp

Thanks @ilyavolodin this was what I was looking for... overlooked in the documentation...

Another query as followup to above response, is there a way I can configure eslint lint to warn for one configuration and error for another configuration...

I am looking for something like max-lines should warn if between 250 - 500 lines and error is file has more than 500 lines.

I can write a custom rule for max line ranges, however, does eslint have an option to switch between warn and error based on config? should this be requested as a feature or does not make sense at all.

@Lakshay-Sood

how can i stop eslint from generating errors on the Current Line?

Haisum

@Haisum92

i think, it was something //eslint-disable-next-line no-console

Lakshay-Sood

@Lakshay-Sood

its not working

Ilya Volodin

@ilyavolodin

@raghukiranp No, this doesn't exist. And it would not be possible with the current setup. Rules don't know anything about reporting levels. They just report an error, it's up to the engine to figure out if that error should be reported as a warning or error based on the config.

@m3dve

Thank you @marcosguti , am going to check it.

Kevin Partington

@platinumazure

@Lakshay-Sood Try this: // eslint-disable-line rule-name (eslint-disable-line does the same line, whereas eslint-disable-next-line does the line below)

Ryan Hirsch

@RyanHirsch

I have a rule that I'm attempting to disable. When I run eslint over the file it still is being flagged as an error. When I run eslint with debug, I see 3 values set in the ConfigArray, error from a plugin, off from my rules, error from the same plugin

The names from the ConfigArray for theses settings are
.eslintrc.js#overrides[2] » plugin:@typescript-eslint/recommended
.eslintrc.js#overrides[2]
.eslintrc.js#overrides[3] » plugin:@typescript-eslint/recommended
if it helps

Ryan Hirsch

@RyanHirsch

Figured it out, the 4th override was pulling in some conf from the third, but no the rule overrides. Our config is way too complicated

Tompouce

@Tompouce-onGit

Hello!
So I'm using ESlint in VScode, and I have the 'quotes' rule set up as such:

"quotes": ["warn", { "allowTemplateLiterals":  true }]

But I get a notification from the ESlint extension telling me that it is invalid:
eslint-error
Has anybody else had this issue and knows a fix?

Jordan Harband

@ljharb

what version of eslint?

Tompouce

@Tompouce-onGit

running eslint --version gives v6.7.2

Jordan Harband

@ljharb

https://eslint.org/docs/rules/quotes the object option is the second one

you need to pass one before it, double, single, or backtick

Tompouce

@Tompouce-onGit

Ooh, okay that makes sense, my bad

Thanks

czaylove

@czaylove

please help me

I have difficulty fixing errors

Kevin Partington

@platinumazure

@czaylove As the error message says, it couldn't find a configuration file. Do you have an ESLint configuration file in your project somewhere?

Tanya Marych

@TMarych_twitter

Hi
I still can not see answer for problem with eslint and "@babel/plugin-proposal-optional-chaining"

"Hi, I installed "@babel/plugin-proposal-optional-chaining": "^7.6.0", and added to .eslintrc.json"

with this error: ESLint couldn't find the plugin "@babel/eslint-plugin-plugin-proposal-optional-chaining".

Can someone help with that, please?

eyelidlessness

@eyelidlessness

i don't know anything beyond just looking at the names, but those appear to be different package names. did you try also installing @babel/eslint-plugin-plugin-proposal-optional-chaining?

or does @babel/plugin-proposal-optional-chaining install that too?

Tanya Marych

@TMarych_twitter

yes, I installed this one and now eslint is broken
