publib

Previously known as jsii-release

A unified toolchain for publishing libraries to popular package managers.

Supports:

• npm
• PyPI
• NuGet
• Maven
• Go (GitHub)

Usage

This is an npm module. You can install it using yarn add publib or npm install publib. In most cases it will be installed as a devDependency in your package.json.

This tool expects to find a distribution directory (default name is dist) which contains "ready-to-publish" artifacts for each package manager.

• dist/js/*.tgz - npm tarballs
• dist/python/*.whl - Python wheels
• dist/nuget/*.nupkg - Nuget packages
• dist/java/** - Maven artifacts in local repository structure
• dist/go/**/go.mod - Go modules. Each subdirectory should have its own go.mod file.

Each publisher needs a set of environment variables with credentials as described below (NPM_TOKEN, TWINE_PASSWORD etc).

Then:

publib

You can customize the distribution directory through publib DIR (the default is dist)

This command will discover all the artifacts based on the above structure and will publish them to their respective package manager.

You can also execute individual publishers:

• publib-maven
• publib-nuget
• publib-npm
• publib-pypi
• publib-golang

npm

Publishes all *.tgz files from DIR to npmjs, GitHub Packages or AWS CodeArtifact.

If AWS CodeArtifact is used as npm registry, a temporary npm authorization token is created using AWS CLI. Therefore, it is necessary to provide the necessary configuration settings, e.g. by passing access key ID and secret access key to this script.

Usage:

npx publib-npm [DIR]

DIR is a directory with npm tarballs (*.tgz). Default is dist/js.

Options (environment variables):

Maven

Publishes all Maven modules in the DIR to Maven Central.

Note that if you signed up at SonaType after February 2021, you need to use this URL: https://s01.oss.sonatype.org (announcement).

Usage:

npx publib-maven [DIR]

DIR is a directory with a local maven layout. Default is dist/java.

Options (environment variables):

How to create a GPG key?

Install GnuPG.

Generate your key:

$ gpg --full-generate-key
# select RSA only, 4096, passphrase

Your selected passphrase goes to MAVEN_GPG_PRIVATE_KEY_PASSPHRASE.

Export and publish the public key:

gpg -a --export > public.pem

Go to https://keyserver.ubuntu.com/ and submit the public key. You can use cat public.pem and copy/paste it into the "Submit Key" dialog.

Export the private key:

gpg -a --export-secret-keys <fingerprint> > private.pem

Now, either set MAVEN_GPG_PRIVATE_KEY_FILE to point to private.pem or export the private key to a single line where newlines are encoded as \n and then assign it to MAVEN_GPG_PRIVATE_KEY:

echo $(cat -e private.pem) | sed 's/\$ /\\n/g' | sed 's/\$$//'

Publish to GitHub Packages
An example GitHub Actions publish step:

- name: Publish package
  run: npx -p publib publib-maven
  env:
    MAVEN_SERVER_ID: github
    MAVEN_USERNAME: ${{ github.actor }}
    MAVEN_PASSWORD: ${{ secrets.GITHUB_TOKEN }}
    MAVEN_REPOSITORY_URL: "https://maven.pkg.github.com/${{ github.repository }}"

NuGet

Publishes all *.nupkg to the NuGet Gallery.

Usage:

npx publib-nuget [DIR]

DIR is a directory with Nuget packages (*.nupkg). Default is dist/dotnet.

Options (environment variables):

Publish to GitHub Packages
You can publish to GitHub Packages instead, with the following options:

• Set NUGET_SERVER to https://nuget.pkg.github.com/[org or user].
• Set NUGET_API_KEY to a token with write packages permissions.
• Make sure the repository url in the project file matches the org or user used for the server

PyPI

Publishes all *.whl files to PyPI.

Usage:

npx publib-pypi [DIR]

DIR is a directory with Python wheels (*.whl). Default is dist/python.

Options (environment variables):

Golang

Pushes a directory of golang modules to a GitHub repository.

Usage:

npx publib-golang [DIR]

DIR is a directory where the golang modules are located (default is dist/go). Modules can be located either in subdirectories, (e.g 'dist/go/my-module/go.mod') or in the root (e.g 'dist/go/go.mod').

If you specify the VERSION env variable, all modules will recieve that version, otherwise a version file is expected to exist in each module directory. Repository tags will be in the following format:

• For a module located at the root: v${module_version} (e.g v1.20.1)
• For modules located inside subdirectories: <subdir-name>/v${module_version} (e.g my-module/v3.3.1)

Options (environment variables):

Publish to CodeArtifact for testing

This package contains the publib-ca CLI tool which is intended to use to publish packages to CodeArtifact for testing (in a pipeline, before publishing to the actual public package managers).

Use the following commands:

publib-ca create [--no-gc] [--no-login] creates a new CodeArtifact repository with a random name, with upstreams configured for all supported public package managers. By default this command runs the gc and login subcommands automatically.

publib-ca login --repo NAME [--cmd COMMAND] logs in to a CodeArtifact repository and prepares some files that configure package managers for use with this CodeArtifact repository. If --cmd is given, the command is run in an environment where all supported package managers have been configured for the given repository. Otherwise, activate these settings in the current bash shell by running source ~/.publib-ca/usage/activate.bash. This will set some environment variables and copy some files into the current directory. (Note: the CodeArtifact repository used here does not have to be created using publib-ca create. It is fine if it already existed beforehand).

publib-ca gc collects old repositories created using publib-ca create.

publib-ca publish [--repo NAME] DIRECTORY publishes all packages in the given directory to the given repository. If --repo is not given, the most recently logged-into repository is used, if the login session is still valid.
