## Why GitHub URLs Get So Long
GitHub URLs concatenate the owner name, repository name, branch name, and file path. For example, a permalink pointing to a specific line in a specific file looks like this:
`github.com/organization/repository-name/blob/a1b2c3d4e5f6/src/components/authentication/LoginForm.tsx#L42-L58`
Links to Issue and Pull Request comments also include fragments like `#issuecomment-1234567890`, often exceeding 150 characters in total. Code review diff links can exceed 200 characters when file paths and hashes are combined.
Pasting these long URLs into Slack threads or emails causes the URL to dominate the message, reducing communication efficiency.
## Alternatives After git.io Was Discontinued
GitHub once provided an official short URL service called `git.io`. However, new URL creation was stopped in 2022, and existing short URL redirects were gradually disabled. This discontinuation eliminated the official means of shortening GitHub URLs.
Alternative options include:
- Using a short URL service on your own domain - Operating short URLs with a custom domain - Creating redirect pages in combination with GitHub Pages
In OSS projects, the practice of using a project-specific subdomain (e.g., `go.project-name.dev/issue-123`) for short URLs is growing.
## Using Short URLs in READMEs
A GitHub repository's README is the face of the project and the document seen by the most people. Managing links in the README with short URLs offers several benefits.
### Simplifying Badge URLs
It is common to display CI status badges, coverage badges, and license badges at the top of a README, but the image URLs and link URLs for each badge are long, making the Markdown source code hard to read. Using short URLs makes badge Markdown concise and README editing easier.
### Pathways to Documentation Sites
Many OSS projects maintain documentation sites separate from their GitHub repositories. When linking from the README to various pages on the documentation site, short URLs provide flexibility for destination changes. Even if the documentation site's URL structure changes, you only need to update the short URL redirect destination, with no README modifications required.
## Notification Links in CI/CD Pipelines
Sending Slack or Teams notifications when CI/CD pipelines fail is a widespread practice. Using short URLs for the links in these notification messages improves readability.
### Implementation Pattern
In a GitHub Actions workflow, incorporate short URL generation into the step that sends Slack notifications on build failure. Specifically, send the failed workflow run URL to the short URL API and include the returned short URL in the Slack message.
The advantage of this approach is not only that notification messages become compact, but also that click analytics can measure "what percentage of engineers who received the notification actually checked the logs." If the notification review rate is low, this serves as a basis for improving notification recipients or message content.
### Application to Deploy Notifications
Short URLs are also effective in deploy completion notifications. By organizing multiple URLs in a notification message - the deployed environment URL, the PR link for changes, and the rollback procedure documentation link - with short URLs, you can quickly access the necessary information even in emergencies.
## Use Cases in OSS Projects
### Embedding Short URLs in Issue Templates
It is common to include links to contribution guides and codes of conduct in bug report and feature request Issue templates. By using short URLs for these links, template modifications become unnecessary when guideline URLs change.
### Use in Release Notes
Release notes contain numerous links to related Issues and PRs. Using short URLs improves release note readability and allows users to quickly access details of changes they are interested in.
Books on developer productivity can also be found on Amazon.
## Operational Rules for Development Teams
When operating short URLs within a development team, establishing the following rules ensures smooth operations:
- Unify slug naming conventions (e.g., `repo-issue-123`, `repo-pr-456`) - Set expiration dates for temporary links (review requests, etc.) - Create permanent links (documentation, guidelines, etc.) without expiration - Manage the short URL directory in Notion or a Wiki so the entire team has access
By documenting these rules in the README's `CONTRIBUTING.md`, new contributors can quickly adapt to the workflow. Short URLs are a small tool, but they have the power to elevate the efficiency of the entire development workflow.
