Github’s URL organization is shown below. This is useful when you need to process or automate linking to Github.
User’s home on Github: https://github.com/<user>
Repository’s home on Github: https://github.com/<user>/<repo>
Path to a repo file on master branch: https://github.com/<user>/<repo>/blob/master/<path-to-file>. The file is rendered inside the Github UI, with syntax highlighting and formatting. Note the blob parent before the master branch name.
Path to a repo file on master branch rendered raw: https://github.com/<user>/<repo>/raw/master/<path-to-file>. Note the raw parent before the master branch name. Github redirects this raw file URL to: https://raw.githubusercontent.com/<user>/<repo>/master/<path-to-file>.
Path to a repo directory on master branch: https://github.com/<user>/<repo>/tree/master/<path-to-dir>. Notice the tree parent before the master branch name.
Could you use the same URL prefix for both directories and files? Yes, you can either use tree or blob for both. It does not matter. Github will redirect the URLs back so that tree is used for directories and blob is used for files.
Path to directory or file in repository in arbitrary branch: https://github.com/<user>/<repo>/blob/<branch-name>/<path-to-dir>. The URL format is the same even if the branch name itself has slashes.
