Description

What

Replaces the bare config:base in renovate.json with a hardened,
low-noise setup for this public repo:

  • Base: config:best-practices + :pinAllExceptPeerDependencies
    (matches our pinned-deps style) + schedule:nonOfficeHours (IST).
  • Caps: prConcurrentLimit: 3, prHourlyLimit: 2 so Renovate
    can't spam PRs.
  • Patch-only automerge, gated on high/very-high Merge Confidence
    and 3-day minimumReleaseAge; minor 7 days manual, major manual.
  • Security fixes (isVulnerabilityAlert) bypass the schedule and
    the stability delay, grouped under security fixes + security label.
  • pnpmDedupe on updates, weekly lock-file maintenance,
    rebaseWhen: conflicted to cut empty rebases.
  • One PR per dep for patch+minor (separateMinorPatch: false),
    separate PRs for majors.

Also removes a rangeStrategy: replace that was silently overriding
the pin preset, so the 4 still-ranged deps (http-errors,
jsonwebtoken, nodemailer, passport-google-oauth20) pin on
their next update like the rest.

Validation

  • renovate-config-validator: passes.
  • No app code touched, renovate.json only.

Follow-ups (manual checks)

  • Confirm branch protection: if "require branches up to date"
    is on, patch automerge PRs may stall with rebaseWhen: conflicted.
  • Node engines/devEngines bumps stay manual (no version file
    for Renovate to track).

Checklist

  • Documentation updated
  • Under a feature flag
  • Database changes
  • Breaking changes
  • Tested during development

Summary by CodeRabbit

  • Chores
    • Automated dependency updates now follow improved scheduling and concurrency limits.
    • Security-related updates receive priority handling and can be released outside normal update windows.
    • Patch updates may be automatically merged after a waiting period when confidence is high.
    • Minor updates require a longer review period, while major updates are not automatically merged.
    • GitHub Actions updates are grouped together, and lock files are maintained automatically.

Walkthrough

The Renovate configuration now uses best-practice presets, limits update activity, enables vulnerability alerts and lock-file maintenance, and defines rules for security, patch, minor, major, and GitHub Actions updates.

Use the`automergeSchedule` option to define times of week or month during which Renovate may automerge its PRs. The default value for`automergeSchedule` is "at any time", which functions the same as setting a`null` schedule. To configure this option refer to`schedule` as the syntax is the same. ... When`platformAutomerge` is enabled, Renovate enqueues the platform PR automerge at time of creation, so the schedule specified in`automergeSchedule` cannot be followed. If it&`#39`;s essential that automerging only happens within the specific`automergeSchedule` time window, then you need to set`platformAutomerge` to`false` and instead rely on Renovate&`#39`;s automerge instead of the platform one. <title>Minimum Release Age - Renovate Docs</title> https://docs.renovatebot.com/key-concepts/minimum-release-age/ `minimumReleaseAge` is a feature that requires Renovate to wait for a specified amount of time before suggesting a dependency update. ... For example, `minimumReleaseAge=14 days` would ensure that a package update is not suggested by Renovate until 14 days after its release, which allows plenty of time to allow security researchers and automated security tools to catch malicious intent in packages. ... Note: Renovate will wait for the set duration to pass for each separate version. Renovate does not wait until the package has seen no releases for x time-duration(`minimumReleaseAge`). ... When the time passed since the release is less than the set `minimumReleaseAge`: Renovate adds a "pending" status check to that update&`#39`;s branch.

We recommend specifying minimum release age in both your Renovate and package manager configuration. ... Renovate&`#39`;s concept of `minimumReleaseAge` is set independently to your package manager&`#39`;s configuration, and is used by Renovate to decide whether to suggest dependency updates. Renovate does not currently have the ability to determine the `minimumReleaseAge` from your package manager&`#39`;s configuration. ... When `minimumReleaseAge` is configured, Renovate passes `--before= ` to npm commands during lock file generation. This ensures that npm only resolves package versions that were available before the cooldown threshold, protecting against newly published (and potentially malicious) transitive dependencies. ...

In Renovate 42, the absence of a release timestamp will be treated as if the release is not yet past the timestamp, which provides a safer default. Prior to Renovate 42, we would treat the dependency without a release timestamp as if it has passed the `minimumReleaseAge`, and will immediately suggest that dependency update.

You may start to automerge development dependencies like Prettier, or ESLint when the linter passes. Or you may decide to automerge any`patch` type upgrades, by using the default:automergePatch preset. ... #### Wait two weeks before automerging third-party dependencies¶ ... If you`automerge` third-party dependencies, we recommend setting minimumReleaseAge to`"14 days"`. By waiting two weeks before automerging the dependencies, you give the upstream registries time to pull malicious dependencies, before Renovate merges them. If you want a third-party dependency update now, instead of waiting two weeks, you can request the update from the Dependency Dashboard. <title>Merge Confidence - Renovate Docs</title> https://docs.renovatebot.com/merge-confidence/ Merge Confidence - Renovate Docs # Merge Confidence¶ Look at the Merge Confidence badges before merging to: - Prevent updates which break in production - See at a glance if you should update Merge Confidence finds and flags undeclared breaking releases. It analyzes test and release adoption data from the Mend Renovate App users. ## Pull request badges¶ Merge Confidence adds the following badges to your pull requests: - Age: The age of the package - Adoption: The percentage of this package&`#39`;s users (within Renovate) which are using this release - Passing: The percentage of updates which have passing tests for this package - Confidence: The confidence level for this update ## Supported platforms¶ Merge Confidence badges for pull requests are available on any supported platform or Renovate distribution, including Mend Remediate. ## Supported languages¶ Renovate will show Merge Confidence badges for these languages: | Language | Datasource | | --- | --- | | Golang | `go` | | JavaScript | `npm` | | Java | `maven` | | Python | `pypi` | | .NET | `nuget` | | PHP | `packagist` | | Ruby | `rubygems` | We plan to support more languages soon. ## Enabling and disabling¶ If you use the Mend Renovate App then the badges are enabled automatically. If you&`#39`;re self-hosting Renovate, you can enable the badges by adding the `mergeConfidence:all-badges` preset to the `extends` array in your Renovate config: ``` { "extends": ["mergeConfidence:all-badges"] } ``` Note The `mergeConfidence:age-confidence-badges` preset can be used to only show the Age and Confidence badges. If you want to disable the badges in the Mend Renovate App, add the `mergeConfidence:all-badges` preset to the `ignorePresets` array in your config: ``` { "ignorePresets": ["mergeConfidence:all-badges"] } ``` ## Confidence levels and their meaning¶ Merge Confidence uses the following confidence levels: - Low: We think the update contains breaking changes. Often this is expected because it&`#39`;s a `major` version update, but updates can have unknown breaking changes - Neutral: We don&`#39`;t have enough data about the update, or we can&`#39`;t decide if the update should be Low or High confidence - High: We rank updates as High confidence when the combination of `Age`, `Adoption` and `Passing` tests means there&`#39`;s a very low chance of breaking changes - Very High: We only use this for updates which are months old and have either high `Adoption` or have very high test `Passing` scores ## How it works¶ The Mend Renovate App created millions of pull requests on `github.com` to help developers update their dependencies since 2017. We bundle and analyze metrics such as package `Age`, package `Adoption`, and `Passing` tests. This way we can find packages that have undeclared breaking changes. ### Algorithm¶ The algorithm that decides on the values is private and is not something we plan to share. Similar to a search engine&`#39`;s algorithm, we plan to adjust and improve it over time, for example by using historical data to set a baseline confidence level for packages. ### Data¶ We plan to expose much more of the data via a companion website, such as number of users of a package and popular repositories which already updated to the version in question. ## Merge Confidence Workflows¶ If you are a paying Mend customer, or you are an Open Source project who has access to Mend Renovate Community (OSS) Cloud, you will have access to Merge Confidence Workflows. This makes it possible to introduce more intelligent workflows, such as "only raise a PR once the update is in High confidence" or "automerge Very High confidence updates". ### Package ranking¶ npm packages less than three days old can be unpublished, which can result in a service impact if you have updated to a package that gets unpublished. This is why npm packages can only get the High Confidence badge when they are at least three days old. ### Percentage value…[truncated] <title>MergeConfidence Presets - Renovate Docs</title> https://docs.renovatebot.com/presets-mergeConfidence/ MergeConfidence Presets - Renovate Docs Skip to content # MergeConfidence Presets ### mergeConfidence:age-confidence-badges¶ Show only the Age and Confidence Merge Confidence badges for pull requests. ``` { "packageRules": [ { "matchDatasources": [ "go", "maven", "npm", "nuget", "packagist", "pypi", "rubygems" ], "matchUpdateTypes": [ "patch", "minor", "major" ], "prBodyColumns": [ "Package", "Change", "Age", "Confidence" ] } ] } ``` --- ### mergeConfidence:all-badges¶ Show all Merge Confidence badges for pull requests. ``` { "packageRules": [ { "matchDatasources": [ "go", "maven", "npm", "nuget", "packagist", "pypi", "rubygems" ], "matchUpdateTypes": [ "patch", "minor", "major" ], "prBodyColumns": [ "Package", "Change", "Age", "Adoption", "Passing", "Confidence" ] } ] } ``` ---

Restrict patch auto-merge to non-office hours.

automerge: true can merge a qualifying patch during office hours. The confidence matcher narrows eligibility, and the 3-day minimumReleaseAge delays eligibility, but neither setting restricts the merge window. schedule:nonOfficeHours governs branch creation. Add automergeSchedule. If platform-native auto-merge is enabled, set platformAutomerge to false.
