# Upgrade Dependencies: Bump, Fix and Open a PR Source: https://maito.app/workflows/upgrade-a-dependency Maito bumps the library on a branch, fixes what breaks, runs your tests and opens a pull request that lists every change and what to check before merging. Bump a library, fix what breaks and open a pull request. [Engineering](https://maito.app/workflows/team/engineering) · [Software](https://maito.app/workflows/industry/software) · When you ask · Updated October 19, 2026 Works with - Slack - Email ## How do you upgrade a dependency? To upgrade a dependency, ask Maito in Slack which library and version. It reads the release notes, bumps it on a branch, fixes the code that breaks, runs your tests and build, then opens a pull request listing each change. It also flags requirements like a newer Node version in your CI setup. ## How it's done today Upgrades get put off until they're painful. ## What Maito does 1. Read the release notes 2. Upgrade and fix breaking changes 3. Run tests 4. Open a PR ## Example **Alex** (4:10 PM): upgrade React Router to the latest version. **Maito** (4:38 PM): PR #918 is open: React Router 6.22 to 7.9. 187 tests pass, build is green. What broke and how I fixed it: • Imports moved from react-router-dom to react-router: 4 files • 2 loaders used the removed json() helper and now return plain objects 6 files changed in total, plus the lockfile. **Catch:** this version needs Node 20, and our CI workflow still runs Node 18. I changed .github/workflows/ci.yml to 20. If your deploy image is on 18, it needs the same bump before you merge. From the release notes and the migration guide. Nothing is merged. Want me to check the deploy config for the Node version? ## How to set it up When you ask Upgrade a dependency Set up Nothing to set up. Ask in Slack or by email whenever you need it. ## What it won't do It tests what your tests cover. Behavior with no test, or problems in production only, can still appear after the upgrade. ## Questions ### Does it merge the pull request? No. It opens the pull request and a person reviews and merges. ### What if tests fail after the upgrade? It fixes what it can, and tells you which failures remain and why. It does not hide failing tests. ### Can it handle major version upgrades? Yes. It reads the migration guide and changes the affected files, but a large major upgrade deserves a careful human review. ## More engineering workflows - [Turn a ticket into a tested pull request Hand over a well-scoped ticket and get back a pull request with tests.
