How to create slug url in nuxtjs without folder?

What i need is this:

1. www.mysite.com/first-post
2. www.mysite.com/second-post
3. www.mysite.com/third-post

dynamic urls and without “blog” before urls.

Instead of this:

1. www.mysite.com/blog/first-post
2. www.mysite.com/blog/second-post
3. www.mysite.com/blog/third-post

What structure folder or configuration i need to make this possible?
