Build status NPM Version

A decentralized personal data server inspired by Solid and Decentralized Web Node.

Background

Life Server is personal data server written in Node.js, originally based on MIT's Solid Server.

Audience

This server is intended for the following audiences:

  1. (primarily) Myself. I'm using this as an experimental platform for incubating and implementing various Solid-related and Solid-adjacent specifications and standards.
  2. (hopefully) Other developers of user centric offline-first decentralized applications.
  3. (to a much smaller extent) End-users interested in running their own file sharing server (a minimal Dropbox/Google Drive sort of setup). This server is not really ready for mainstream (or even early adopter) usage.
  4. (almost not at all) For system administrators / potential service providers interested in running their own multi-user data server.

To put it another way, due to a shortage of engineering resources, the priorities will be: Developer QoL (Quality of Life) over User QoL over DevOps QoL.

Roadmap

This is an experimental server focusing on interop exploration and rapid feature iteration. "Move fast and break things (and then fix them just as quickly)", to use a tired cliché.

Roadmap Phase One (Complete)

This phase focused on general cleanup and refactoring from the source node-solid-server v4 baseline. (See Phase One details.)

Roadmap Phase Two

This phase focuses on exploring some advanced features that may make it into Solid spec proposals, as well as integration with external Solid-adjacent projects and specs.

  • Fix/update Dockerfile
  • DID Integration
    • Generate a did:web DID and corresponding keys for the Server itself, during installation.
    • Generate a did:web DID and corresponding keys for each user on account registration.
    • (in progress) Implement DIDAuth for wallet, hook it up to Login page.
    • Add did:key support
    • Add Veres One DIDs support
  • Interop with Verifiable Credentials
  • Implement an in-Memory based LDP backend, to go alongside the FS backend.
  • Integrate or implement Static OIDC Client Registration functionality, to make interfacing with server-side Solid apps easier.
  • Investigate level of effort required to switch from the current oidc-op OpenID Connect Provider library to a more widely supported one, such as Filip's node-oidc-provider lib.
  • Implement a server-side metadata mechanism, to support being able to record who created a resource
  • (in progress) Experimental integration with CouchDB (for synchronizing of graphs and documents to mobile and offline-first clients).
  • Explore using an Encrypted Data Vault as a storage backend. This would require some basic Key Management capability, possible based on the Web KMS spec.
  • Interop with the Fediverse by implementing ActivityPub protocol.

Differences from Solid Server

Since node-solid-server (NSS) is being deprecated in favor of inrupt/pod-server, this repo intends to be another compatible implementation (the more the merrier!).

  • Works on Windows 10 (WSL2)

Does not support:

  • Using an external WebID on signup
  • acl:origin checking or Trusted Apps (uses solid-permissions
    instead of acl-check.js for access control)
  • acl:trustedOrigin (removed on purpose during refactoring)
  • Password strength checking on account signup.
  • Enforcement of storage space quotas
  • WebID-TLS local authentication
  • WebSockets
  • Globbing

Value Proposition for Developers

See Solid and Life Server Value Proposition for Developers doc.

Install

Pre-requisites: Node.js v14+

  • Linux, Mac OS X, or Windows 10
  • Node 14+

To run Life Server, you will first need to install Node.js. (The developers recommend using nvm to install Node.)

Install life-server from Github

git clone https://github.com/interop-alliance/life-server.git
cd life-server
npm install

Edit /etc/hosts (development/testing only)

life-server's test suite uses the following localhost domains: nic.localhost, tim.localhost, and nicola.localhost. You will need to create host file entries for these, in order for the tests to pass.

Edit your /etc/hosts file, and append:

# Used for unit testing
127.0.0.1 nic.localhost
127.0.0.1 tim.localhost
127.0.0.1 nicola.localhost

(Optional) Prepare the SSL/TLS certificate

Local/Development: life-server includes a default localhost self-signed TLS certificate in the config/ folder. Advanced users may want to create their own certificates for local testing.

Production: Installing life-server in a production environment will require a valid TLS certificate (self-signed certs will not work). In addition, if you're running the server in Multi User mode, you will need a Wildcard Certificate.

(Optional) Generate a config file

The easiest way to customize life-server is by running the init wizard. This will create a config.dev.js in your current folder:

./bin/server init

Usage

To run your server:

./bin/server start

After startup, the server is available at the configured server URL (by default, https://localhost:7070).

Usage with Docker

See docs/Usage With Docker for details.

Security

TBD

Note: This is an experimental research server, not for production use.

Contribute

Life Server is only possible because of a large community of Solid contributors. A heartfelt thank you to everyone for all of your efforts!
