HFS: HTTP File Server

HFS is a file server offering a virtual file system (vfs). You can easily share a single file instead of the whole folder, or you can rename it, but without touching the real file, just virtually.

This project is in an early stage and distribution will be made easier.

This is a full rewrite of the Delphi version. You won't find all previous features here (yet), but still we got:

Features

• unicode
• virtual file system
• mobile friendly front-end
• search
• accounts
• resumable downloads
• simple website serving

Configuration

At the moment there's no administration UI. You must edit configuration files.

Config

General configuration is read by default from file config.yaml. When not specified, default values will be used. Supported entries are:

• port where to accept http connections. Default is 80.
• vfs the files and folders you want to expose. For details see the dedicated following section.
• log path of the log file. Default is access.log.
• accounts path of the accounts file. Default is accounts.yaml.
• mime command what mime-type to be returned with some files. E.g.: "*.jpg": image/jpeg You can specify multiple entries, or separate multiple file masks with a p|pe. You can use the special value auto to attempt automatic detection.

Virtual File System (VFS)

The virtual file system is a tree of files and folders, collectively called nodes. By default a node is folder, unless you provide for it a source that's a file. Valid keys in a node are:

• name: how to display it. If not provided HFS will infer it from the source.
• source: where to get its content from. Absolute or relative file path, or even http url.
• children: just for folders, specify its virtual children. Value is a list and its entries are nodes.
• hidden: this must not be listed, but it's still downloadable.
• hide: similar to hidden, but it's from the parent node point of view. Use this to hide entries that are read from the source, not listed in the VFS. Value can be just a file name, a mask, or a list of names/masks.
• rename: similar to name, but it's from the parent node point. Use this to change the name of entries that are read from the source, not listed in the VFS. Value is a dictionary, where the key is the original name.
• perm: specify who can see this. Use this to limit access to this node. Value is a dictionary, where the key is the username, and the value is r.
• mime: specify what mime to use for this resource. Use "auto" for automatic detection.
• default: to be used with a folder where you want to serve a default html. E.g.: "index.html". Using this will make mime default to "auto".

Accounts

Accounts are kept in accounts.yaml if any, or you can decide another file by passing parameter --accounts. Inside the file, all accounts should go under accounts: key, as a dictionary where the key is the username. E.g.

accounts:
    admin:
        password: hello123
        belongs: group1
    guest:
        password: guest
    group1:

As soon as the file is read HFS will encrypt passwords in a non-reversible way. For this reason HFS needs that your accounts file is writable.

Building instructions

0. Install Node.js 16+
1. Install Typescript: launch npm -g i typescript
2. Launch npm run build-all in the root

You'll find the output in dist folder.

Now to run it you should cd dist and node .

Plugins

We are slowly introducing a plug-ins system. Each plug-in is a plugin.yaml file sub-folder of plugins folder. You can quickly disable a plug-in by appending -disabled to the plug-in folder.
