Coverage Status

A scalable, light-weight object storage service.

Read this post on why we decided to build a new object storage service.

  • Uses Postgres as its datastore for storing metadata
  • Authorization rules are written as Postgres Row Level Security policies
  • Integrates with S3 as the storage backend (with more in the pipeline!)
  • Extremely lightweight and performant

Architecture

Documentation

Development

  • Copy .env.sample to .env file.
  • Copy .env.test.sample to .env.test.
  • Change GLOBAL_S3_BUCKET and REGION to the name and region of a S3 bucket.
    • If you just want to run the tests and not develop locally, you can skip this step because S3 calls are mocked in our tests.
  • Set up your AWS credentials. Your user must have permissions to s3:PutObject, s3:GetObject, s3:DeleteObject in the bucket you have chosen.

Your root directory should now have both .env and .env.test files.

  • Then run the following:
# this sets up a postgres database and postgrest locally via docker
npm run infra:restart
# Start the storage server
npm run dev

The server should now be running at http://localhost:5000/

The following request should insert and return the list of buckets.

# insert a bucket named avatars
curl --location --request POST 'http://localhost:5000/bucket' \
--header 'Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJyb2xlIjoic2VydmljZV9yb2xlIiwiaWF0IjoxNjEzNTMxOTg1LCJleHAiOjE5MjkxMDc5ODV9.th84OKK0Iz8QchDyXZRrojmKSEZ-OuitQm_5DvLiSIc' \
--header 'Content-Type: application/json' \
--data-raw '{
    "name": "avatars"
}'

# get buckets
curl --location --request GET 'http://localhost:5000/bucket' \
--header 'Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJyb2xlIjoic2VydmljZV9yb2xlIiwiaWF0IjoxNjEzNTMxOTg1LCJleHAiOjE5MjkxMDc5ODV9.th84OKK0Iz8QchDyXZRrojmKSEZ-OuitQm_5DvLiSIc'

Testing

To perform your tests you can run the following command: npm test
