In this blog post, I explain how to use pnpm in GitLab CI and how to authenticate with a private GitLab package registry.
Corepack is an experimental tool that helps you manage the versions of your package managers.
package.json
The packageManager field specifies which package manager is expected to be used. The value is set to pnpm with the preferred version 8.15.4.
{
"packageManager": "pnpm@8.15.4"
}
.gitlab-ci.yml
In order to have pnpm available in every job, it is installed within the before_script. These commands are executed before each job!
before_script:
- corepack enable
- corepack prepare --activate
To also use the cache, it is configured as follows:
cache:
key: $CI_COMMIT_REF_SLUG
paths:
- .pnpm-store
policy: pull-push
before_script:
- pnpm config set store-dir .pnpm-store
The following commands are required to access the private package registry:
before_script:
- pnpm config set @scope:registry https://${CI_SERVER_HOST}/api/v4/projects/${CI_PROJECT_ID}/packages/npm/
- pnpm config set -- //${CI_SERVER_HOST}/api/v4/projects/${CI_PROJECT_ID}/packages/npm/:_authToken ${CI_JOB_TOKEN}
Replace @scope with your package scope. The environment variables CI_SERVER_HOST, CI_PROJECT_ID and CI_JOB_TOKEN are provided by GitLab CI. You do not need to manually create and set a token for the package registry. The CI_JOB_TOKEN is valid as long as the job is running.
Packages can now be downloaded and published.
Complete code example
With this example you can use pnpm in GitLab CI, download packages from the GitLab package registry and also publish them.
.gitlab-ci.yml
image: 'public.ecr.aws/docker/library/node:18-bullseye'
stages:
- build
- deploy
cache:
key: $CI_COMMIT_REF_SLUG
paths:
- .pnpm-store
policy: pull-push
before_script:
- corepack enable
- corepack prepare --activate
- pnpm config set store-dir .pnpm-store
- pnpm config set @scope:registry https://${CI_SERVER_HOST}/api/v4/projects/${CI_PROJECT_ID}/packages/npm/
- pnpm config set -- //${CI_SERVER_HOST}/api/v4/projects/${CI_PROJECT_ID}/packages/npm/:_authToken ${CI_JOB_TOKEN}
- pnpm install
build:
stage: build
script:
- pnpm run build
artifacts:
paths:
- dist/
publish:
stage: deploy
needs:
- job: build
script:
- pnpm publish
