ESLint with type script has bugs (ref eslint/typescript-eslint-parser#438), so use tslint now.
If later on switch to eslint, remeber to recover the following configs:
package.json
"@vue/cli-plugin-eslint": "^3.0.1",
"@vue/eslint-config-standard": "^3.0.1",
"@vue/eslint-config-typescript": "^3.0.1",
