@enstore/server

A lightweight Node.js + TypeScript file server with:

• File listing, reading, and writing (with streaming uploads)
• Authentication & Authorization (file-based user management with bcrypt)
• Role-based access control
• Configurable as:
  • Express middleware
  • Standalone CLI (enstore-server start)
  • Docker container (pull from ghcr.io/ricsam/enstore-server)

Installation

npm install -g @enstore/server

Once installed globally, you have the enstore-server command available.

Usage

1. Run as Express Middleware

You can embed Enstore’s routes in your own Express app by using the middleware factory:

import express from 'express';
import { createEnstoreMiddleware, EnstoreServerConfig } from '@enstore/server';

const app = express();
const config: EnstoreServerConfig = {
  uploadsDirectory: './uploads',
  userFilePath: './users.json',
};

app.use('/enstore', createEnstoreMiddleware(config));

app.listen(3000, () => {
  console.log(`Server running on port 3000`);
});

Here, uploadsDirectory is where files are stored, and userFilePath is the file-based store (users.json) for authentication and role-based permissions.

---

2. Run as CLI

After installing globally:

enstore-server start --port 8080 --users ./users.json --uploads-dir ./uploads

Flags:

• -p, --port <port>: Port the server listens on (defaults to 3000).
• --users <path>: Path to users.json (defaults to ~/.enstore/users.json if not specified).
• -d, --uploads-dir <path>: Directory for uploaded files (defaults to ./uploads).

If you omit flags, Enstore uses sensible defaults (port 3000, ~/.enstore/users.json, ./uploads folder).

Example:

enstore-server start --port 8080 --users /path/to/users.json --uploads-dir /path/to/uploads

---

3. Docker

Pull the pre-built Docker image from ghcr.io/ricsam/enstore-server:

docker pull ghcr.io/ricsam/enstore-server:latest

Example run command:

docker run -d --rm --name enstore \
  -p 3456:3000 \
  -v /host/path/users.json:/app/users.json \
  -v /host/path/uploads:/app/uploads \
  ghcr.io/ricsam/enstore-server:latest

This starts Enstore inside a container listening on port 3000 (mapped to 3456 on the host). The internal port inside the docker container can be changed with the PORT env variable.

An initial admin account can be provided instead of a users.json file:

docker run -d --rm --name enstore \
  -p 3455:3000 \
  -e ADMIN_USERNAME=admin \
  -e ADMIN_PASSWORD=password \
  ghcr.io/ricsam/enstore-server:latest

To run it in a docker compose file you can follow this example:

version: '3'

services:
  enstore:
    image: 'ghcr.io/ricsam/enstore-server:latest'
    environment:
      - ADMIN_USERNAME=admin
      - ADMIN_PASSWORD=password
    ports:
      - "3456:3000"
    volumes:
      - "./uploads:/app/uploads"

Local User Management via CLI

enstore-server user subcommands let you manage the local users.json file directly without running the server. This is useful for adding or updating users offline. The updated file is then used when you start the server.

enstore-server user add <username> <role>
# => Prompts for password, adds user locally to your specified users.json

enstore-server user update <username> [--role <role>] [--password]
# => Can update user role and/or prompt for new password

enstore-server user delete <username>
# => Removes a user

enstore-server user add-role <role> <permissions...>
enstore-server user update-role <role> <permissions...>
enstore-server user delete-role <role>

Flags:

• --users <path>: Path to the users.json file (if omitted, defaults to ~/.enstore/users.json).

Examples:

# Add a new user "alice" with "read-write" role
enstore-server user add alice read-write --users ./users.json

# Update user "alice" role to "admin" and prompt for a new password
enstore-server user update alice --role admin --password --users ./users.json

# Delete user "alice"
enstore-server user delete alice --users ./users.json

# Manage roles
enstore-server user add-role editor read write --users ./users.json
enstore-server user update-role editor read write manageUsers --users ./users.json
enstore-server user delete-role editor --users ./users.json

How User Management Works

Enstore stores users and roles in users.json. The file structure is:

{
  "users": [
    {
      "username": "admin",
      "hashedPassword": "$2b$10$...",
      "role": "admin"
    }
  ],
  "roles": {
    "admin": ["read", "write", "manageUsers"],
    "read-write": ["read", "write"],
    "read-only": ["read"]
  }
}

• hashedPassword is the bcrypt hash of the user’s plaintext password.
• role references a key in roles.
• roles is a map of role names to an array of permission strings (["read", "write", "manageUsers"], etc.).

Local management:

• Use enstore-server user ... subcommands to edit this file locally without starting the server.
• Once you start the server (enstore-server start), it uses the updated file for authentication & authorization.

---

File Storage & Configuration

• Uploads: Files are stored on disk in the directory specified by --uploads-dir. The server provides endpoints to list, read, and write files within that directory.
• Configuration:
  • Port defaults to 3000.
  • users.json path defaults to ~/.enstore/users.json if not specified via --users.
  • Uploads dir defaults to ./uploads.

---

That’s it! Now you can:

• Embed Enstore’s routes in your own Express app.
• Run the CLI (enstore-server start) to launch a standalone server.
• Manage users locally with enstore-server user ....
• Or pull the Docker image ghcr.io/ricsam/enstore-server:latest and run it in a container.
