Automate Dependency Upgrades with AI
Dependency bots are great at telling you an upgrade exists and terrible at the part that actually takes time: making the upgrade work. A version-bump PR that fails CI because of a breaking change isn't done — it's a ticket. So the upgrades pile up, the lockfile drifts, and eventually a security advisory forces a painful catch-up across a dozen majors at once.
Codowave handles the whole upgrade, not just the bump. It updates the version, fixes the breaking changes in your code, runs your tests, and opens a PR that's actually mergeable.
Start your 5-day trialWhy Upgrades Pile Up
The version bump is the easy 5%. The other 95% is:
- Reading the changelog to find what broke.
- Updating call sites for renamed or removed APIs.
- Fixing type errors the new version introduces.
- Updating tests that depended on old behavior.
- Getting CI green.
A bot that opens a bump PR and leaves the breaking changes to you hasn't removed the work — it's just relocated it. So the PRs sit, and the gap between your lockfile and the ecosystem grows until it's a project of its own.
How Codowave Handles an Upgrade
Step 1: It Picks Up the Upgrade
Label upgrade issues (dependencies, upgrade) or let Codowave take bump PRs your dependency bot opened. You scope which packages and how aggressive (patch/minor only, or majors with supervision).
Step 2: It Reads What Changed
For a real upgrade, Codowave looks at the new version's breaking changes — renamed APIs, removed options, changed defaults — and maps them to where your code uses them.
Step 3: It Fixes the Breakage
It updates the call sites, fixes the type errors, and adjusts tests that relied on old behavior. This is the part bots skip and the part that actually matters.
Step 4: It Runs Your Tests and Opens a PR
Codowave runs your suite, confirms the upgrade is green, and opens a PR with the bump, the code changes, and the test results. If CI still fails, its autofix loop diagnoses and pushes a fix to the same branch — bounded by your cost ceiling so it won't thrash.
What Codowave Handles Well Here
| Upgrade Type | Example | Performance |
|---|---|---|
| Patch / minor bumps | "Update lodash 4.17.20 → 4.17.21" | Strong |
| Minor with small API changes | "Update the HTTP client, adjust changed options" | Strong |
| Type-only breakage | "Fix type errors from the new SDK types" | Strong |
| Test fixes from behavior change | "Update tests for the new date library defaults" | Strong |
| Single major upgrade | "Migrate to v3 of the validation library" | Moderate (with review) |
| Framework majors | "Upgrade the web framework across the app" | Use with supervision |
Real Numbers: What to Expect
Based on typical Codowave usage on upgrade work:
- Upgrades handled per week: 6–12, weighted toward patch/minor
- PR merge rate (CI green, human-approved): 70–85% for patch/minor, lower for majors
- Time saved: a minor upgrade that would eat an hour of a developer's afternoon lands as a reviewable PR in minutes
- Cost per merged PR: approximately $1–4 on the Pro plan
Keeping dependencies current continuously is far cheaper — in time and risk — than the forced catch-up after a security advisory.
What It Won't Do
- Force a risky major silently. Big framework migrations are flagged for supervision, not merged autonomously.
- Ignore a failing suite. If an upgrade can't be made green, Codowave returns the partial work with a clear explanation rather than papering over failures.
- Skip tests to pass CI. A test that fails because behavior genuinely changed is updated correctly or flagged — never deleted to force green.
