Possible errors & improvements.

1. When i install config globally, plugin:node/recommended will install into eslint-config-hexo directory (under subdir). And plugin actually not work, because eslint must see node plugin in same level hierarchy. But then i install it locally, node plugin will placed in same level as eslint.

   node -v && npm -v
   v6.14.0
   3.10.10

   [root@localhost ivan-nginx]# npm i -g eslint-config-hexo
   /usr/lib

   npm WARN eslint-config-hexo@3.0.0 requires a peer of eslint@>= 3.1.0 but none was installed.
   npm WARN eslint-plugin-node@5.2.1 requires a peer of eslint@>=3.1.0 but none was installed.

   Solution is — install eslint-plugin-node separately:

   npm i -g eslint-config-hexo eslint-plugin-node

2. There are duplicate parameters in eslint.js: dot-notation and no-multi-str. And i also see other parameters which already by default in eslint:recommended settings. Fixed in Remove unnecessarily overwritten recommended config #6

3. All 'error' strings can be sucessfully replaced by 2: https://eslint.org/docs/user-guide/configuring#configuring-rules

4. No need to define parserOptions: { ecmaVersion: 6 } parameter if env: { es6: true } already defined: https://eslint.org/docs/user-guide/configuring#specifying-parser-options

5. Deprecated parameter 'eqeqeq': ['error', 'allow-null']: https://eslint.org/docs/rules/eqeqeq#allow-null

6. strict option not needed for ES6, because in ES6 this mode turned on by default.

Thank you @theme-next. Those are good suggestions and it looks like @segayuu will incorporate this into his work.
