Merge multiple GitHub repositories into a monorepo while preserving commit history. Each repo will live as a subdirectory. Currently only works in Linux.
Features:
- Merge multiple repos while keeping full history and commit hashes.
- Specify branches of each repo to merge.
- Migrate repos into existing monorepo.
Requirements:
- git version 2.9+.
export MONOREPO_NAME=monorepo # defaults to monorepo
git clone [email protected]:ksindi/monoreaper.git && cd monoreaper/
chmod +x monoreaper.sh
bash monoreaper.sh owner/repo0 owner/repo1
# you can specify another default branch via `owner/repo0/some-branch`.The above script will create a monorepo directory with a README.md file and subdirectores repo0 and repo1. Note only the default branches of each repo will be included.
If you now want to add the monorepo to GitHub:
cd monorepo/
git remote add origin [email protected]:owner/monorepo
git push -f origin masterIf you already have a monorepo and want to merge other repos into it,
all you have to do is include a MONOREPO_DIR env variable:
MONOREPO_DIR=path/to/my/monorepo bash monoreaper.sh owner/repo0 owner/repo1Note that the MONOREPO_DIR must have master as default branch.
- Streamlines ops logic. The overhead of setting up pipelines and deployments is cumbersome.
- Shared codebase introduces shared ownership, naming and style.
- Dependencies across services are easier to manage.
- Searching code across multiple repos is a hassle.
- Lots of great tools that take advantage of monorepos. See awesome-monorepo.
