The rule no-undef doesn't work?

[Napoleon-Jm]

The "no-undef" rule is not work in cos-eslint, but it's worked on my vscode(same js code).
And other lint error tips' ok, did I miss something to config?

There is nothing special on my coc config, almost is default.

Add below code to my js file, and saved,

abc=bac

Both of them(abc, bcd) should be lint a "no-undef", while vscode does, but coc not.

@chemzqm The fileContent as the code upon, has a abc = b, that will caused a undef lint tip in vscode, but coc doesn't.

[chemzqm]

The output is from tsserver, not eslint.

[chemzqm]

Maybe you have "typescript.showUnused": false config

[Napoleon-Jm]

The eslintrc has upload on my first replay,

:CocCommand workspace.showOutput

just give me two options.... watchman or tsserver

[chemzqm]

Seems you don't have eslint server running.
