verdaccio-aws-s3-storage

📦 AWS S3 storage plugin for Verdaccio

This plugin was forked based on verdaccio-s3-storage built in Typescript + other features added along the time. Both plugins might have vary in behaviour since then, we recommend use the AWS plugin on this repo due is under control of Verdaccio community and constantly upated.

See it in action

• Test on Docker + LocalStack + Verdaccio 4 + S3 Plugin example.
• Using docker-compose on this repo based on verdaccio-minio developed by barolab.
• Feel free to propose new ways to run this plugin.

Basic Requirements

• AWS Account (in case you are using the cloud)
• Verdaccio server (4.0) (for 3.x use verdaccio-s3-storage instead)

npm install -g verdaccio

Usage

npm install verdaccio-aws-s3-storage

This will pull AWS credentials from your environment.

In your verdaccio config, configure

store:
  aws-s3-storage:
    bucket: your-s3-bucket
    keyPrefix: some-prefix # optional, has the effect of nesting all files in a subdirectory
    region: us-west-2 # optional, will use aws s3's default behavior if not specified
    endpoint: https://{service}.{region}.amazonaws.com # optional, will use aws s3's default behavior if not specified
    s3ForcePathStyle: false # optional, will use path style URLs for S3 objects
    tarballACL: private # optional, use public-read to work with CDN like Amazon CloudFront
    accessKeyId: your-access-key-id # optional, aws accessKeyId for private S3 bucket
    secretAccessKey: your-secret-access-key # optional, aws secretAccessKey for private S3 bucket
    sessionToken: your-session-token # optional, aws sessionToken for private S3 bucket

The configured values can either be the actual value or the name of an environment variable that contains the value for the following options:

• bucket
• keyPrefix
• region
• endpoint
• accessKeyID
• secretAccessKey
• sessionToken

store:
  aws-s3-storage:
    bucket: S3_BUCKET # If an environment variable named S3_BUCKET is set, it will use that value. Otherwise assumes the bucket is named 'S3_BUCKET'
    keyPrefix: S3_KEY_PREFIX # If an environment variable named S3_KEY_PREFIX is set, it will use that value. Otherwise assumes the bucket is named 'S3_KEY_PREFIX'
    endpoint: S3_ENDPOINT # If an environment variable named S3_ENDPOINT is set, it will use that value. Otherwise assumes the bucket is named 'S3_ENDPOINT'
    ...

store properties can be defined for packages. The storage location corresponds to the folder in s3 bucket.

packages:
  '@scope/*':
    access: all
    publish: $all
    storage: 'scoped'
  '**':
    access: $all
    publish: $all
    proxy: npmjs
    storage: 'public'

Specify ACL of Tarball Files

You can specify ACL of tarball files in S3 by the tarballACL configuration, set to 'private' by default. To enable S3 integrated CDN service (Amazon CloudFront for example), set tarballACL to 'public-read' to grant tarball files anonymous read permission.

store:
  aws-s3-storage:
    tarballACL: public-read

Developer Testing

In case of local testing, this project can be used self-efficiently. Four main ingredients are as follows:

• config.yaml, see verdaccio documentation
• The provided docker file allows to test the plugin, with no need for main verdaccio application
• The provided docker-compose also provides minio in orchestration as a local substitute for S3 backend
• Create and set content of registry.envs as follows. This file does not exist on the repo and should be generated manually after cloning the project.

AWS_ACCESS_KEY_ID=foobar
AWS_SECRET_ACCESS_KEY=1234567e
AWS_DEFAULT_REGION=eu-central-1
AWS_S3_ENDPOINT=https://localhost:9000/
AWS_S3_PATH_STYLE=true

Execute the docker image for testing

You need the latest docker installed in your computer

docker-compose up

By default there is no bucket created, you might need to browse http://127.0.0.1:9000/minio/ and create the example bucket manually named rise and then restart docker-compose up.

The default values should work out of the box. If you change anything, make sure the corresponding variables are set in other parts of the ingredient as well.
