Run semantic-release only after all tests succeeded

The semantic-release command must be executed only after all the tests in the CI build pass. If the build runs multiple jobs (for example to test on multiple Operating Systems or Node versions) the CI has to be configured to guarantee that the semantic-release command is executed only after all jobs are successful. This can be achieved with Travis Build Stages, CircleCI Workflows, Codeship Deployment Pipelines, GitLab Pipelines, Wercker Workflows, GoCD Pipelines or specific tools like travis-deploy-once.

See CI configuration recipes for more details.

Authentication

semantic-release requires push access to the project Git repository in order to create Git tags. The Git authentication can be set with one of the following environment variables:

GIT_CREDENTIALS must be the Git username and password in the format <username>:<password>.

Alternatively the Git authentication can be set up via SSH keys.

Most semantic-release plugins require setting up authentication in order to publish to a package manager registry. The default @semantic-release/npm and @semantic-release/github plugins require the following environment variables:

See each plugin documentation for the environment variables to set up.

The authentication token/credentials have to be made available in the CI service via environment variables.

See CI configuration recipes for more details on how to configure environment variables in your CI service.

Automatic setup with semantic-release-cli

​semantic-release-cli allows for easy installation of semantic-release in your Node project as well as setting up the CI configuration:

npm install -g semantic-release-cli
​
cd your-module
semantic-release-cli setup

See the semantic-release-cli documentation for more details.
