Renovate Bot

Renovate Bot provides automated dependency updates with extensive configuration options. For design system consumers, Renovate offers powerful features for grouping related packages, scheduling updates, and automating merge policies. Its flexibility makes it popular for complex dependency management needs.

What Is Renovate Bot

Renovate is an automated dependency update tool available as a GitHub App, GitLab integration, self-hosted solution, or CLI. It creates pull requests to update dependencies and supports sophisticated configuration for managing update behavior.

Compared to simpler alternatives, Renovate offers more configuration options including regex package matching, custom managers, replacement rules, and advanced scheduling. This flexibility helps manage design system updates effectively.

How Renovate Bot Works

Renovate configuration lives in renovate.json or a similar config file. Understanding its features enables optimized design system update management.

Package rules define update behavior for matching packages. Rules can target packages by name patterns, update types, or other criteria. Design system packages can have dedicated rules specifying their update handling.

Grouping combines multiple packages into single PRs. Group configuration specifies which packages to combine and how to name the resulting PR. Design system packages typically benefit from grouping.

Scheduling controls when Renovate creates PRs. Schedule expressions define allowed windows for updates. Teams can restrict updates to specific days, times, or avoid certain periods.

Auto-merge configuration determines automatic merge behavior. Rules specify when updates can merge without review, typically based on update type and test results.

Key Considerations

• Use package rules to customize design system update behavior
• Configure grouping to reduce PR volume
• Set schedules matching team availability
• Define appropriate auto-merge policies
• Consider preset configurations for common patterns

Common Questions

How does Renovate grouping work for design systems?

Renovate grouping combines related package updates into single PRs. Several patterns work well for design systems.

Pattern-based grouping matches package names. Configuration like matchPackagePatterns: [”^@design-system/”] groups all packages matching the pattern. This automatically captures new packages added to the scope.

Group configuration defines the group. Within packageRules, setting groupName: “design-system” creates named groups. The group name appears in PR titles and helps identify updates.

Major updates can be excluded from groups. Adding matchUpdateTypes: [“minor”, “patch”] to group rules keeps major updates separate for focused review. Major updates often require more attention.

Monorepo awareness helps Renovate understand related packages. If the design system uses changesets or similar tools, Renovate can detect monorepo relationships and handle updates appropriately.

What Renovate presets help with design system updates?

Renovate presets provide reusable configuration. Several built-in and custom presets help with design system management.

Built-in presets provide common configurations. config:base includes sensible defaults. :pinAllExceptPeerDependencies helps with version strategy. :semanticCommits enables conventional commit messages.

Organization presets share configuration across repositories. Creating a preset repository with design system rules lets all consumer projects inherit consistent configuration.

Preset sharing with extends references presets. Configuration like “extends”: [“github>org/renovate-config”] pulls preset configuration from a repository.

Custom presets can encapsulate complex rules. If design system updates need specific handling, a preset like “design-system-updates” can package those rules for easy reuse.

Preset combination layers configurations. Extending multiple presets and then overriding specific settings enables both reuse and customization.

Summary

Renovate Bot provides flexible automated dependency updates with extensive configuration options. Package rules, grouping, scheduling, and auto-merge features enable sophisticated design system update management. Presets help share effective configurations across projects and organizations.
