Monorepo package management workflows (FREE)
One project or Git repository can contain multiple different subprojects or submodules that are all packaged and published individually.
Publishing different packages to the parent project
The number and name of packages you can publish to one project is not limited. You can accomplish this by setting up different configuration files for each package. See the documentation for the package manager of your choice since each has its own specific files and instructions to follow to publish a given package.
The example here uses NPM.
In this example,
MyProject is the parent project. It contains a sub-project
Foo in the
MyProject/ |- src/ | |- components/ | |- Foo/ |- package.json
The goal is to publish the packages for
Foo. Following the instructions in the
GitLab NPM registry documentation,
you can publish
MyProject by modifying the
package.json file with a
and by doing one of the following:
- Modify your local NPM configuration with CLI commands like
npm config set.
- Save a
.npmrcfile in the root of the project specifying these configuration settings.
If you follow the instructions, you can publish
MyProject by running
npm publish from the root
Foo is almost exactly the same. Follow the same steps while in the
Foo needs its own
package.json file, which you can add manually by using
Foo also needs its own configuration settings. Since you are publishing to the same place, if you
npm config set to set the registry for the parent project, then no additional setup is
necessary. If you used an
.npmrc file, you need an additional
.npmrc file in the
Be sure to add
.npmrc files to the
.gitignore file or use environment variables in place of your
access tokens to prevent your tokens from being exposed. This
.npmrc file can be identical to the
one you used in
MyProject. You can now run
npm publish from the
Foo directory and you can
Foo separately from
You could follow a similar process for Conan packages. However, instead of
package.json, you have
conanfile.py in multiple locations within the project.
Publishing to other projects
A package is associated with a project on GitLab, but the package does not need to be associated
with the code in that project. When configuring NPM or Maven, you only use the
Project ID to set
the registry URL that the package uploads to. If you set this to any project that you have access to
and update any other configuration similarly depending on the package type, your packages are
published to that project. This means you can publish multiple packages to one project, even if
their code does not exist in the same place. See the project registry workflow documentation
for more information.
