Hypercloud is a public peer service for Dat archives. It provides a HTTP-accessible interface for creating an account and uploading Dats.
Features:
- Simple Dat uploading and hosting
- Easy to replicate Dats, Users, or entire datasets between Hypercloud deployments
- Configurable user management
- Easy to self-deploy

Setup
Clone this repository, then run
npm install
cp config.defaults.yml config.development.yml
Modify config.development.yml to fit your needs, then start the server with npm start.
Configuration
Before deploying the service, you absolutely must modify the following config.
Basics
dir: ./.hypercloud # where to store the data brandname: Hypercloud # the title of your service hostname: hypercloud.local # the hostname of your service port: 8080 # the port to run the service on rateLimiting: true # rate limit the HTTP requests? defaultDiskUsageLimit: 100mb # default maximum disk usage for each user pm2: false # set to true if you're using https://keymetrics.io/
Lets Encrypt
You can enable lets-encrypt to automatically provision TLS certs using this config:
letsencrypt: debug: false # debug mode? must be set to 'false' to use live config email: 'foo@bar.com' # email to register domains under
If enabled, port will be ignored and the server will register at ports 80 and 443.
Admin Account
The admin user has its credentials set by the config yaml at load. If you change the password while the server is running, then restart the server, the password will be reset to whatever is in the config.
admin: email: 'foo@bar.com' password: myverysecretpassword
UI Module
The frontend can be replaced with a custom npm module. The default is hypercloud-ui-vanilla.
ui: hypercloud-ui-vanilla
HTTP Sites
Hypercloud can host the archives as HTTP sites. This has the added benefit of enabling dat-dns shortnames for the archives. There are two possible schemes:
sites: per-user
Per-user will host archives at username.hostname/archivename, in a scheme similar to GitHub Pages. If the archive-name is == to the username, it will be hosted at username.hostname.
Note that, in this scheme, a DNS shortname is only provided for the user archive (username.hostname).
sites: per-archive
Per-archive will host archives at archivename-username.hostname. If the archive-name is == to the username, it will be hosted at username.hostname.
By default, HTTP Sites are disabled.
Closed Registration
For a private instance, use closed registration with a whitelist of allowed emails:
registration: open: false allowed: - alice@mail.com - bob@mail.com
Reserved Usernames
Use reserved usernames to blacklist usernames which collide with frontend routes, or which might be used maliciously.
registration: reservedNames: - admin - root - support - noreply - users - archives
Session Tokens
Hypercloud uses Json Web Tokens to manage sessions. You absolutely must replace the secret with a random string before deployment.
sessions: algorithm: HS256 # probably dont update this secret: THIS MUST BE REPLACED! # put something random here expiresIn: 1h # how long do sessions live?
Jobs
Hypercloud runs some jobs periodically. You can configure how frequently they run.
# processing jobs jobs: popularArchivesIndex: 30s # compute the index of archives sorted by num peers userDiskUsage: 5m # compute how much disk space each user is using deleteDeadArchives: 5m # delete removed archives from disk
Emailer
Todo, sorry
Tests
Run the tests with
npm test
To run the tests against a running server, specify the env var:
REMOTE_URL=http://{hostname}/ npm test
