Install and Configure Graphite for Your Monorepo (2026)

Install the Graphite CLI with Homebrew on macOS or Linux:

brew install graphite

On Windows or for alternative methods, download the binary from Graphite’s releases page. After installation, authenticate with your Git provider:

gt auth –token YOUR_GITHUB_TOKEN # or for GitLab gt auth –gitlab –token YOUR_GITLAB_TOKEN

Initialize Graphite in your monorepo by setting up the workspace at the repository root:

cd your-monorepo gt repo init

For Turborepo monorepos, create a .graphite/config file that defines workspace paths and affected builds:

{ “workspace”: { “paths”: [“apps/*”, “packages/*”, “libs/*”] }, “ci”: { “affected”: “turbo run build –filter=…{HEAD^}” } }

For Nx monorepos, configure the affected command with Nx syntax:

{ “workspace”: { “paths”: [“apps/*”, “libs/*”] }, “ci”: { “affected”: “nx affected:build –base=HEAD^” } }

This configuration lets Graphite understand your monorepo layout and run CI only for affected projects. For more configuration details, see the Gitar documentation.

Create and Manage Graphite Stacked PRs Step by Step

Stacked PRs in monorepos work best when you follow a clear sequence that keeps dependencies explicit. Use these steps as a repeatable workflow.

1. Create the base branch for your feature:

gt stack create shared-lib-update # Make changes to shared library git add packages/shared-lib/ gt commit -m “Update shared authentication library”

2. Create dependent branches that build on the base:

gt stack create frontend-auth-integration –from shared-lib-update # Update frontend to use new auth library git add apps/frontend/ gt commit -m “Integrate new auth library in frontend” gt stack create backend-auth-integration –from shared-lib-update # Update backend services git add apps/backend/ gt commit -m “Update backend auth service integration”

3. Submit the entire stack for review:

gt submit stack

This command creates pull requests for all branches in the stack and wires up dependencies. Each PR shows only the diff for that specific change instead of the full stack.

4. Monitor and sync dependencies:

gt status # Shows current stack state and any conflicts gt sync # Pulls latest changes and updates the stack

Expected output shows clean dependency chains where each PR builds on its predecessor. The frontend and backend integration PRs depend on the shared library update so reviewers can see how changes relate.

Keep Monorepo Stacks in Sync with Restack Commands

Maintaining synchronized stacks in monorepos requires regular restacking as your main branch evolves. Use the comprehensive restack command:

gt restack –all

This command updates all branches in your stack with changes from the main branch and resolves conflicts automatically when possible. For Turborepo monorepos, pair restacking with affected builds:

gt restack –all && turbo run build –filter=…{HEAD^}

For Nx monorepos, follow the affected command pattern:

gt restack –all && nx affected:build –base=HEAD^

Troubleshooting Nx Restack Failures with Logs and Fixes

Restack failures in Nx monorepos often trace back to dependency graph conflicts. Typical errors look like:

Error: Cannot restack – conflicting changes in nx.json Conflict in libs/shared-utils/project.json

Resolve these issues by editing the conflicted files, then forcing the restack:

gt restack –force –branch your-branch-name

For persistent problems, reset the stack and recreate it:

gt stack reset gt stack create new-base-branch

The troubleshooting guide in the documentation provides detailed CI failure analysis steps.

Optimize Monorepo CI with Graphite Stacks

Configuring CI for affected builds keeps Graphite stacked PRs fast and cost effective. For GitHub Actions with Turborepo, use the dorny/paths-filter@v3 action as a standard pattern:

name: CI on: [push, pull_request] jobs: filter-paths: runs-on: ubuntu-latest outputs: frontend: ${{ steps.filter.outputs.frontend }} backend: ${{ steps.filter.outputs.backend }} steps: – uses: dorny/paths-filter@v3 id: filter with: filters: | frontend: – ‘apps/frontend/**’ – ‘packages/shared/**’ backend: – ‘apps/backend/**’ – ‘packages/shared/**’ build-frontend: needs: filter-paths if: needs.filter-paths.outputs.frontend == ‘true’ runs-on: ubuntu-latest steps: – run: turbo run build –filter=frontend…

This setup runs jobs only when relevant paths change and reduces CI/CD time and costs significantly. For GitLab CI, configure parent-child pipelines with conditional execution:

trigger_frontend: trigger: include: .gitlab/ci/frontend.yml rules: – changes: – apps/frontend/**/* – packages/shared/**/*

Recent benchmarks show Shopify reduced CI failures by 60% and reclaimed 27,061 engineering hours annually using Graphite’s merge queue with virtual zones in their monorepo.

Merge, Clean Up, and Apply Monorepo Best Practices

Complete your stacked PR workflow by landing changes in dependency order:

gt stack land

This command merges all PRs in the stack sequentially so dependencies remain satisfied. Configure your merge strategy to match team preferences:

# For rebase-based workflows gt config merge.strategy rebase # For merge commit workflows gt config merge.strategy merge

Clean up merged branches automatically:

gt cleanup

Resolve Turborepo Merge Conflicts with the CLI

Merge conflicts in Turborepo configuration files respond well to a structured approach. Conflicts in turbo.json often appear as:

<<<<<<< HEAD “pipeline”: { “build”: { “dependsOn”: [“^build”] } ======= “pipeline”: { “build”: { “dependsOn”: [“^build”, “^lint”] } >>>>>>> feature-branch

Combine both dependency requirements, stage the resolved file, and continue the merge:

git add turbo.json gt continue

Effective monorepo stacked PRs keep individual PRs small, group changes by logical zones such as frontend, backend, and shared libraries, and use descriptive branch names that show dependencies.

Gitar also integrates with major CI platforms such as GitHub Actions, GitLab CI, CircleCI, and Buildkite so it fits into existing pipelines. The documentation covers CI analysis features and platform support in depth.

FAQ

How to manage dependencies in a monorepo with Graphite?

Dependency management in monorepos with Graphite starts with logical stacks where shared library updates live on a base branch and consumer applications use dependent branches. Run gt stack create base-branch for foundational changes, then gt stack create dependent-branch –from base for each consuming application. The gt submit stack command creates linked PRs that reviewers can assess independently while still seeing the dependency chain. Gitar enhances this workflow with AI code review, CI failure analysis, and automated workflows during the trial period.

What are Graphite PR stacks?

Graphite PR stacks are ordered sequences of dependent pull requests where each PR builds on the previous one. This structure lets developers break large features into smaller, reviewable chunks. Unlike a single large PR that accumulates all changes, stacks support parallel development and review of related work. Each PR shows only its specific diff, which keeps reviews focused and manageable and reduces merge conflicts in complex monorepo environments.

Graphite vs polyrepo for dependency management?

Graphite stacked PRs shine in monorepos because they manage cross-package dependencies atomically inside one repository. Polyrepo setups require coordinating changes across multiple repositories, which often introduces version drift and integration problems. Monorepos with Graphite support atomic updates where shared library changes and consumers are developed, reviewed, and merged together. This approach removes much of the complexity of semantic versioning and keeps dependent code synchronized with library updates.

Does Gitar work with Turborepo and Nx stacks?

Gitar supports Turborepo and Nx monorepos and provides full codebase context for AI code review and CI failure analysis. It works across GitHub, GitLab, and CI systems such as GitHub Actions, GitLab CI, CircleCI, and Buildkite. When CI failures occur, Gitar analyzes them with full repository context during the Team Plan trial.

How does Gitar handle merge conflicts in stacked PRs?

Gitar helps surface issues that cause merge conflicts early by combining CI failure analysis with AI code review. The platform evaluates failures in the context of your entire repository and presents actionable insights in a single dashboard comment. This guidance reduces the manual effort required to keep complex stacked PR workflows healthy.

Mastering Graphite stacked PR dependencies in monorepos depends on consistent CLI workflows, tuned CI configurations, and smart automation.
