Filesystem Guide

MeeseOS uses an URI for filesystem paths.

name:/path#fragment

Mountpoints

A mountpoint is an object that defines a name, label and which adapter to use. You can have several mountpoints using the same adapter, but resolves to different locations.

An example would be the provided meeseOS mountpoint that resolves to {root}/dist (where "root" is the MeeseOS path) via the system adapter.

[info] By default the system adapter will resolve home directories in the vfs/ folder of your installation. You can change this behaviour by modifying vfs.root in server config

Adding Mountpoints

You can add mountpoints by updating your configuration files:

Note that the name must match in both configurations

Note you'll have to rebuild and reload server afterwards

Client

{
  vfs: {
    mountpoints: [{
      name: "temp",
      label: "Temporary Files",
      adapter: "system", // You can leave this out as "system" is default
      attributes: {}
     }]
   }
}

Available attributes:

Server

{
  vfs: {
    mountpoints: [{
      name: "temp",
      adapter: "system", // You can leave this out as "system" is default
      attributes: {
        root: "/tmp"
      }
    }]
  }
}

Available attributes:

Assigning Groups

You can lock down mountpoints and VFS methods with groups.

Example configuration (server):

{
  vfs: {
    mountpoints: [{
      name: "meeseOS",
      attributes: {
        root: "{root}/dist",
        groups: [
          // Only allow users with the "admin" group
          "admin",

          // Or, alternativelly do the same, but only for the "readdir"
          // endpoint
          {
            readdir: ["admin"]
          }
        ]
      }
    }]
  }
}

Adapters

An Adapter is a module that makes the actual requests on behalf of MeeseOS APIs.

An example is the included system which uses the APIs provided by the server, which uses the underlying node fs module to provide a filesystem via the underlying OS.

Adding Adapters

You can add custom adapters via the VFS service provider:

Client

import customAdapter from "custom-adapter";

meeseOS.register(VFSServiceProvider, {
  args: {
    adapters: {
      custom: customAdapter
    }
  }
});

Server

const customAdapter = require("custom-adapter");

meeseOS.register(VFSServiceProvider, {
  args: {
    adapters: {
      webdav: customAdapter
    }
  }
});
