ESLint + TypeScript issue?

[marlo22]

Hi, I have a problem (probably) with plugin.

This is my rollup config:

const prepareRollupConfig = ({ input, output, name, plugins = [] }) => ({
  input: INPUT_DIR + input,
  output: {
    file: OUTPUT_DIR + output,
    name,
  },
  plugins: [resolve({ browser: true }), commonjs(), typescript(), eslint(), ...plugins],
});

Here is .eslintrc

{
  "parser": "@typescript-eslint/parser",
  "plugins": [
    "@typescript-eslint"
  ],
  "extends": [
    "eslint:recommended",
    "plugin:@typescript-eslint/eslint-recommended",
    "plugin:@typescript-eslint/recommended"
  ]
}

When I build a project almost everything is fine, but not all. Some errors and warnings are thrown but I don't know why, for example: I see a lot of no-var rule warnings. In my code I use only const and let declarations, but in the console I still see these warns. Interesting is fact that when I run ESLint through CLI (./node_modules/.bin/eslint .) this problem not occur. Because of that I think that this problem is connected with rollup plugin rather than ESLint's ecosystem directly. If I disable no-var rule the problem of course goes away.

Help me, please. Thank you. :)

You could try putting the eslint() call as the first item in your plugins array. If this doesn't work, I'd be happy if you could try the same thing with my plugin: https://github.com/robinloeffel/rollup-plugin-eslint. I've created it since the one here isn't maintained anymore, I suppose.

@shaoweidong and @IMakiMaki, could one of you guys please open up an issue on my repository with an exact reproduction? https://github.com/robinloeffel/rollup-plugin-eslint/issues/new

@robinloeffel

I tried to install your repository @rbnlffl/rollup-plugin-eslint instead of this one, it looks like no errors and warnings are thrown by 'no-var'.Thanks.
