depandabot-batch-review

CLI tool for batch review of Dependabot PRs and security alerts across all of a user or organization's repositories.

Note: The alert-reviewing functionality is being migrated to a separate hypothesis/dependabot-alerts tool.

Introduction

This tool enables efficient review of Dependabot activity across an organization or user account. This includes:

Reviewing and merging PRs to update dependencies
Reviewing security alerts

It is built on the GitHub GraphQL API.

Installation

Install Poetry
Clone this repository and install Python dependencies with:
```
poetry install
```

Authorization

In order of precedence, this tool will obtain a GitHub API token from:

The GITHUB_TOKEN environment variable
The GitHub CLI if installed and logged in
Prompting for a token when the tool is run

For reviewing security alerts, the token must have permission to query alerts in the target organization/user account. For reviewing updates, this token must have permission to read and merge PRs in the target organization/user account.

Reviewing security alerts

To review open security alerts for an organization, run:

./alerts.sh [organization]

This will search for all open Dependabot alerts against repositories in the organization and list their details.

If the same alert is reported multiple times against a single repository, only one instance will be shown.

To review open security alerts for repositories belonging to a user, run:

./alerts.sh --user [user]

Resolving alerts

To resolve an alert, you can:

Merge a Dependabot PR that has been created. This can be done either through the GitHub UI or using this tool.
Manually create a PR to update affected dependencies.
Dismiss an alert if the risk to a project is low or the alert is not relevant.
Archive the GitHub project if it is no longer being maintained. This will disable all vulnerability reports.
Set up custom Dependabot alert rules on a per repository basis. This can be used to fine tune which alerts are reported based on the lockfile path and other criteria.

See https://docs.github.com/en/code-security/dependabot/dependabot-alert-rules/about-dependabot-alert-rules

Slack notifications

If run with the --slack flag, the tool will send a report of vulnerabilities found to the Slack channel specified using the SLACK_CHANNEL environment variable. An authentication token for a Slack app must be provided via the SLACK_TOKEN environment variable. You can create a Slack app at https://api.slack.com/apps.

Reviewing updates

To review Dependabot dependency update PRs for a user or organization, run:

./review.sh [organization]

This will query for open PRs from Dependabot in the organization organization, which can also be a GitHub username. It will group the updates by package name, then go through each package in alphabetical order, show a summary of the PRs updating that package and prompt for an action.

For each package it will show the name, version ranges of updates and status of continuous integration checks. At this point you can then choose to review release notes for the update, merge all PRs in the group that have passed CI checks, or see individual PRs in the group.

Grouped updates

When using Dependabot's grouped updates feature, this tool will treat the group name of a PR like a package name for the purposes of grouping PRs across repositories.

If for example you had configured a group called "babel" in multiple repositories which matched all npm dependencies whose name matches the pattern "@babel/", then this tool would group together all the PRs that updated the "babel" group across different repositories.

1 updates for group babel:
Versions:
  @babel/preset-typescript 7.22.15 -> 7.23.0
  @babel/core 7.22.17 -> 7.23.0
Checks: 1 passed

In this example, there is one PR updating a group called "babel", which updates two different packages.

Filtering updates

There are several options to filter PRs:

--label <label> finds PRs with a specific label. By default Dependabot adds a label for the language (eg. "javascript").
--repo-filter <pattern> finds PRs only in repositories that match a given pattern
--type <type> finds PRs that update a specific type of package. Type values come from the branch names of Dependabot PRs, which have the form dependabot/{package_type}/{package_name}-{version}. For example "pip" or "npm_and_yarn".

Limitations

This tool currently only fetches up to 100 PRs per run. To continue reviewing after processing these, simply run the tool again.
