GitLab CI Env

GitLab CI Env returns an object containing all of the predefined environment variables provided by GitLab CI.

Usage

const gitlabEnv = require('gitlab-ci-env');

const projectName = gitlabEnv.ci.project.name;
const commitSha = gitlabEnv.ci.commit.sha;

Variable reference

The GitLab predefined environment variables are grouped by function. Generally this hierarchy can be derived from the name, for example CI_COMMIT_REF_NAME and CI_COMMIT_REF_SLUG are provided via ci.commit.ref.name and ci.commit.ref.slug respectively. There are some exceptions, which are included as properties in the most appropriate functional location.

A complete mapping of the GitLab predefined environment variables to the object provided by this module is given below for reference (values equal variable names).
