README

In Q2 2018, this project was renamed from filemanager to filebrowser, a new GitHub organization was created and the main repo was moved from hacdias/filemanager to filebrowser/filebrowser. Old refs will work, because permanent redirects are set up. However, we suggest every contributor to update the remote URLs in their local clones. See Changing a remote's URL.

Moreover, the previously unique repo was split into multiple pieces: frontend, logo, caddy... At the same time, the official docker image was changed to filebrowser/filebrowser. Users are encouraged to check their sources and update them accordingly.

CircleCI Go Report Card Documentation Version Chat IRC

filebrowser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit your files. It allows the creation of multiple users and each user can have its own directory. It can be used as a standalone app or as a middleware.

Table of contents

Getting started

You can find the Getting Started guide on the documentation.

Features

Easy login system.

Login Page

Listings of your files, available in two styles: mosaic and list. You can delete, move, rename, upload and create new files, as well as directories. Single files can be downloaded directly, and multiple files as .zip, .tar, .tar.gz, .tar.bz2 or .tar.xz.

Mosaic Listing

File Browser editor is powered by Codemirror and if you're working with markdown files with metadata, both parts will be separated from each other so you can focus on the content.

Markdown Editor

On the settings page, a regular user can set its own custom CSS to personalize the experience and change its password. For admins, they can manage the permissions of each user, set commands which can be executed when certain events are triggered (such as before saving and after saving) and change plugin's settings.

Settings

We also allow the users to search in the directories and execute commands if allowed.

Users

We support multiple users and each user can have its own scope and custom stylesheet. The administrator is able to choose which permissions should be given to the users, as well as the commands they can execute. Each user also have a set of rules, in which he can be prevented or allowed to access some directories (regular expressions included!).

Users

File Browser allows you to search through your files and it has some options. By default, your search will be something like this:

this are keywords

If you search for that it will look at every file that contains "this", "are" or "keywords" on their name. If you want to search for an exact term, you should surround your search by double quotes:

"this is the name"

That will search for any file that contains "this is the name" on its name. It won't search for each separated term this time.

By default, every search will be case insensitive. Although, you can make a case sensitive search by adding case:sensitive to the search terms, like this:

this are keywords case:sensitive

Documentation

Overview

Package filebrowser provides a web interface to access your files wherever you are. To use this package as a middleware for your app, you'll need to import both File Browser and File Browser HTTP packages. 

import (
	fm "github.com/filebrowser/filebrowser"
	h "github.com/filebrowser/filebrowser/http"
)

Then, you should create a new FileBrowser object with your options. In this case, I'm using BoltDB (via Storm package) as a Store. So, you'll also need to import "github.com/filebrowser/filebrowser/bolt". 

db, _ := storm.Open("bolt.db")

m := &fm.FileBrowser{
	NoAuth: false,
	Auth: {
		Method: "default",
		LoginHeader: "X-Fowarded-User"
	},
	DefaultUser: &fm.User{
		AllowCommands: true,
		AllowEdit:     true,
		AllowNew:      true,
		AllowPublish:  true,
		Commands:      []string{"git"},
		Rules:         []*fm.Rule{},
		Locale:        "en",
		CSS:           "",
		Scope:         ".",
		FileSystem:    fileutils.Dir("."),
	},
	Store: &fm.Store{
		Config: bolt.ConfigStore{DB: db},
		Users:  bolt.UsersStore{DB: db},
		Share:  bolt.ShareStore{DB: db},
	},
	NewFS: func(scope string) fm.FileSystem {
		return fileutils.Dir(scope)
	},
}

The credentials for the first user are always 'admin' for both the user and the password, and they can be changed later through the settings. The first user is always an Admin and has all of the permissions set to 'true'.

Then, you should set the Prefix URL and the Base URL, using the following functions: 

m.SetBaseURL("/")
m.SetPrefixURL("/")

The Prefix URL is a part of the path that is already stripped from the r.URL.Path variable before the request arrives to File Browser's handler. This is a function that will rarely be used. You can see one example on Caddy filemanager plugin.

The Base URL is the URL path where you want File Browser to be available in. If you want to be available at the root path, you should call: 

m.SetBaseURL("/")

But if you want to access it at '/admin', you would call: 

m.SetBaseURL("/admin")

Now, that you already have a File Browser instance created, you just need to add it to your handlers using m.ServeHTTP which is compatible to http.Handler. We also have a m.ServeWithErrorsHTTP that returns the status code and an error.

One simple implementation for this, at port 80, in the root of the domain, would be: 

http.ListenAndServe(":80", h.Handler(m))
