|

[](https://travis-ci.org/fuse-friends/fuse-native)
|
||||
|
||||
Fully maintained fuse bindings for Node that aims to cover the entire FUSE api
|
||||
Multithreaded FUSE bindings for Node JS.
|
||||
|
||||
## Features
|
||||
|
||||
* N-API support means we ship prebuilds and in general works on new Node.js releases.
|
||||
* Multithreading support means multiple calls to FUSE can run in parallel.
|
||||
* Close to feature complete in terms of the the FUSE API.
|
||||
* Embedded shared library support means users do not have to install FUSE from a 3rd party.
|
||||
* API support for initial FUSE kernel extension configuration so you can control the user experience.
|
||||
|
||||
## Installation
|
||||
```
|
||||
npm install fuse-bindings
|
||||
npm i fuse-native --save
|
||||
```
|
||||
|
||||
Created because [fuse4js](https://github.com/bcle/fuse4js) isn't maintained anymore and doesn't compile on iojs
|
||||
|
||||
## Requirements
|
||||
|
||||
You need to have FUSE installed
|
||||
|
||||
* On Linux/Ubuntu `sudo apt-get install libfuse-dev`
|
||||
* On OSX install [OSXFuse](http://osxfuse.github.com/)
|
||||
|
||||
## Usage
|
||||
|
||||
Try creating an empty folder called `mnt` and run the below example
|
||||
|
||||
## Example
|
||||
```js
|
||||
var fuse = require('fuse-bindings')
|
||||
|
||||
fuse.mount('./mnt', {
|
||||
const ops = {
|
||||
readdir: function (path, cb) {
|
||||
console.log('readdir(%s)', path)
|
||||
if (path === '/') return cb(0, ['test'])
|
||||
cb(0)
|
||||
if (path === '/') return cb(null, ['test'])
|
||||
return cb(Fuse.ENOENT)
|
||||
},
|
||||
getattr: function (path, cb) {
|
||||
console.log('getattr(%s)', path)
|
||||
if (path === '/') {
|
||||
if (path === '/') return cb(null, stat({ mode: 'dir', size: 4096 }))
|
||||
if (path === '/test') return cb(null, stat({ mode: 'file', size: 11 }))
|
||||
return cb(Fuse.ENOENT)
|
||||
},
|
||||
open: function (path, flags, cb) {
|
||||
return cb(0, 42)
|
||||
},
|
||||
release: function (path, fd, cb) {
|
||||
return cb(0)
|
||||
},
|
||||
read: function (path, fd, buf, len, pos, cb) {
|
||||
var str = 'hello world'.slice(pos, pos + len)
|
||||
if (!str) return cb(0)
|
||||
buf.write(str)
|
||||
return cb(str.length)
|
||||
}
|
||||
}
|
||||
|
||||
const fuse = new Fuse(mnt, ops, { debug: true })
|
||||
fuse.mount(function (err) {
|
||||
fs.readFile(path.join(mnt, 'test'), function (err, buf) {
|
||||
// buf should be 'hello world'
|
||||
})
|
||||
})
|
||||
```
|
||||
|
||||
## API
|
||||
In order to create a FUSE mountpoint, you first need to create a `Fuse` object that wraps a set of implemented FUSE syscall handlers:
|
||||
|
||||
#### `const fuse = new Fuse(mnt, handlers, opts = {})`
|
||||
Create a new `Fuse` object.
|
||||
|
||||
`mnt` is the string path of your desired mountpoint.
|
||||
|
||||
`handlers` is an object mapping syscall names to implementations. The complete list of available syscalls is described below. As an example, if you wanted to implement a filesystem that only supports `getattr`, your handle object would look like:
|
||||
```js
|
||||
{
|
||||
getattr: function (path, cb) {
|
||||
if (path === '/') return process.nextTick(cb, null, stat({ mode: 'dir', size: 4096 }))
|
||||
if (path === '/test') return process.nextTick(cb, null, stat({ mode: 'file', size: 11 }))
|
||||
return process.nextTick(cb, Fuse.ENOENT)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
`opts` can be include:
|
||||
```
|
||||
displayFolder: 'Folder Name', // Add a name/icon to the mount volume on OSX,
|
||||
debug: false, // Enable detailed tracing of operations.
|
||||
force: false, // Attempt to unmount a the mountpoint before remounting.
|
||||
mkdir: false // Create the mountpoint before mounting.
|
||||
```
|
||||
Additionally, all (FUSE-specific options)[http://man7.org/linux/man-pages/man8/mount.fuse.8.html] will be passed to the underlying FUSE module (though we use camel casing instead of snake casing).
|
||||
|
||||
#### `Fuse.isConfigured(cb)`
|
||||
|
||||
Returns `true` if FUSE has been configured on your machine and ready to be used, `false` otherwise.
|
||||
|
||||
#### `Fuse.configure(cb)`
|
||||
|
||||
Configures FUSE on your machine by enabling the FUSE kernel extension.
|
||||
You usually want to do this as part of an installation phase for your app.
|
||||
Might require `sudo` access.
|
||||
|
||||
#### `Fuse.unconfigure(cb)`
|
||||
|
||||
Unconfigures FUSE on your machine. Basically undos any change the above
|
||||
method does.
|
||||
|
||||
See the CLI section below on how to run these commands from the command line if you prefer doing that.
|
||||
|
||||
### FUSE API
|
||||
Most of the [FUSE api](http://fuse.sourceforge.net/doxygen/structfuse__operations.html) is supported. In general the callback for each op should be called with `cb(returnCode, [value])` where the return code is a number (`0` for OK and `< 0` for errors). See below for a list of POSIX error codes.
|
||||
|
||||
#### `ops.init(cb)`
|
||||
|
||||
Called on filesystem init.
|
||||
|
||||
#### `ops.access(path, mode, cb)`
|
||||
|
||||
Called before the filesystem accessed a file
|
||||
|
||||
#### `ops.statfs(path, cb)`
|
||||
|
||||
Called when the filesystem is being stat'ed. Accepts a fs stat object after the return code in the callback.
|
||||
|
||||
``` js
|
||||
ops.statfs = function (path, cb) {
|
||||
cb(0, {
|
||||

||||
namemax: 1000000
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
#### `ops.getattr(path, cb)`
|
||||
|
||||
Called when a path is being stat'ed. Accepts a stat object (similar to the one returned in `fs.stat(path, cb)`) after the return code in the callback.
|
||||
|
||||
``` js
|
||||
ops.getattr = function (path, cb) {

## API
|
||||
#### `ops.fgetattr(path, fd, cb)`
|
||||
|
||||
#### `fuse.mount(mnt, ops)`
|
||||
Same as above but is called when someone stats a file descriptor
|
||||
|
||||
Mount a new filesystem on `mnt`.
|
||||
Pass the FUSE operations you want to support as the `ops` argument.
|
||||
#### `ops.flush(path, fd, cb)`
|
||||
|
||||
#### `fuse.unmount(mnt, [cb])`
|
||||
Called when a file descriptor is being flushed
|
||||
|
||||
Unmount a filesystem
|
||||
#### `ops.fsync(path, fd, datasync, cb)`
|
||||
|
||||
#### `fuse.unmountSync(mnt)`
|
||||
Called when a file descriptor is being fsync'ed.
|
||||
|
||||
Unmount a filesystem synchroniously
|
||||
#### `ops.fsyncdir(path, fd, datasync, cb)`
|
||||
|
||||
## FUSE operations
|
||||
Same as above but on a directory
|
||||
|
||||
Most of the [FUSE api](http://fuse.sourceforge.net/doxygen/structfuse__operations.html) is supported.
|
||||
#### `ops.readdir(path, cb)`
|
||||
|
||||
* `ops.init(cb)`
|
||||
* `ops.access(path, cb)`
|
||||
* `ops.statfs(path, cb)`
|
||||
* `ops.getattr(path, cb)`
|
||||
* `ops.fgetattr(path, fd, cb)`
|
||||
* `ops.flush(path, fd, cb)`
|
||||
* `ops.fsync(path, fd, cb)`
|
||||
* `ops.fsyncdir(path, fd, cb)`
|
||||
* `ops.readdir(path, cb)`
|
||||
* `ops.truncate(path, size, cb)`
|
||||
* `ops.ftruncate(path, fd, size, cb)`
|
||||
* `ops.readlink(path, result, cb)`
|
||||
* `ops.chown(path, uid, gid, cb)`
|
||||
* `ops.chmod(path, mode, cb)`
|
||||
* `ops.setxattr(path, name, buf, length, offset, flags, cb)`
|
||||
* `ops.getxattr(path, name, buf, length, offset, cb)`
|
||||
* `ops.open(path, flags, cb)`
|
||||
* `ops.opendir(path, flags, cb)`
|
||||
* `ops.read(path, fd, buf, length, position, cb)`
|
||||
* `ops.write(path, fd, buf, length, position, cb)`
|
||||
* `ops.release(path, fd, cb)`
|
||||
* `ops.releasedir(path, fd, cb)`
|
||||
* `ops.create(path, mode, cb)`
|
||||
* `ops.utimens(path, cb)`
|
||||
* `ops.unlink(path, cb)`
|
||||
* `ops.rename(src, dest, cb)`
|
||||
* `ops.link(src, dest, cb)`
|
||||
* `ops.symlink(src, dest, cb)`
|
||||
* `ops.mkdir(path, cb)`
|
||||
* `ops.rmdir(path, cb)`
|
||||
* `ops.destroy(cb)`
|
||||
Called when a directory is being listed. Accepts an array of file/directory names after the return code in the callback
|
||||
|
||||
The goal is to support 100% of the API.
|
||||
``` js
|
||||
ops.readdir = function (path, cb) {
|
||||
cb(0, ['file-1.txt', 'dir'])
|
||||
}
|
||||
```
|
||||
|
||||
When using `getattr` you should return a stat object after the status code,
|
||||
`readdir` expects an array of directory names, `open` an optional fd and
|
||||
`utimens` an object with `mtime` and `atime` dates.
|
||||
#### `ops.truncate(path, size, cb)`
|
||||
|
||||
Both `read` and `write` passes the underlying fuse buffer without copying them to be as fast as possible.
|
||||
Called when a path is being truncated to a specific size
|
||||
|
||||
You can pass [mount options](http://blog.woralelandia.com/2012/07/16/fuse-mount-options/) (i.e. `direct_io` etc) as `ops.options = ['direct_io']`
|
||||
#### `ops.ftruncate(path, fd, size, cb)`
|
||||
|
||||
## Error codes
|
||||
Same as above but on a file descriptor
|
||||
|
||||
The available error codes are exposes as well as properties. These include
|
||||

|
||||
|
||||
```
|
||||
npm install -g fuse-native
|
||||
fuse-native is-configured # checks if the kernel extension is already configured
|
||||
fuse-native configure # configures the kernel extension
|
