# Permalinks

# Background

Before 1.x.x, VuePress retrieves all Markdown files in the documents source directory and defines the page links based on the file hierarchy. For example if you have the following file structure:

├── package.json
└── source
    ├── _post
    │   └── intro-vuepress.md
    ├── index.md
    └── tags.md

Then you will get following available pages:


Yet, for a blog system, we hope that the link of a post can be customized. VuePress started supporting this feature, known as permalink, from 1.0.0. Then, the actual pages would be:


We have seen the shadow of the blog. Let’s continue to look down.

A permalink is a URL that is intended to remain unchanged for a long time, yielding a hyperlink that is less susceptible to link rot1. VuePress supports a flexible way to build permalinks, allowing you to use template variables.

The default permalink is /:regular.

You can configure globally to apply it for all pages:

// .vuepress/config.js
module.exports = {
  permalink: '/:year/:month/:day/:slug'

You can also set permalink on a page only, and it will have a higher priority than the global settings.

📝 hello.md:

title: Hello World
permalink: /hello-world
