How to get eslint in vscode to use the correct compilerOptions.target from tsconfig.json-CodePudding

eslint in vscode is reporting the error:

Type 'this' can only be iterated through when using the '--downlevelIteration' flag or with a '--target' of 'es2015' or higher."

I would have thought that eslint would look at my tsconfig.json and see that I have set the TypeScript compilerOptions.target to es2015.

For good measure, I also added the following to my package.json

  "eslintConfig": {
    "env": {
      "node": true,
      "es2015": true
    }
  }

Despite the correct configuration, eslint is still reporting the error ts(2802).

How can I get the built-in eslint in vscode to know that my target is es2015 and not report that error?

CodePudding user response：

You dont have to add eslintconfig in package json.

Make sure you have in tsConfig.json -> compilerOptions.target: "target": "es2017" and in package.json => devDependencies :

"eslint": "^8.17.0"
"@angular-eslint/builder": "13.5.0",
"@angular-eslint/eslint-plugin": "13.5.0",
"@angular-eslint/eslint-plugin-template": "13.5.0",
"@angular-eslint/schematics": "13.5.0",
"@angular-eslint/template-parser": "13.5.0",
"@typescript-eslint/eslint-plugin": "5.27.1",
"@typescript-eslint/parser": "5.27.1"

then be sure you have .eslintrc.json file in the root of the project, next to package.json and tsconfig.json files

It work for me.
