A node.js implementation of the min-stream and continuable based fs interface for js-git.

File System Interface

This module implements the following functions from the fs interface which is described in detail at

  • stat(path) -> continuable
  • read(path, [encoding]) -> continuable
  • write(path, value, [encoding]) -> continuable
  • readStream(path, [options]) -> source
  • writeStream(path, [options]) -> sink
  • unlink(path) -> continuable
  • readlink(path) -> continuable
  • symlink(path, target) -> continuable
  • readdir(path) -> source
  • rmdir(path) -> continuable
  • mkdir(path) -> continuable
  • rename(path, target) -> continuable
var fs = require('min-fs');
// Streaming copy a file 
// Set up a source, the file isn't actually opened till the stream is read from. 
var source = fs.readStream("input.txt");
// Set up a sink.  The file isn't actually opened yet. 
var sink = fs.writeStream("copy.txt");
// Hook the source to the sink, but still don't create either file or start moving yet. 
var continuable = sink(source);
// Now, create both files and stream the contents.  If there is a problem it will be reported here. 
// Otherwise the continuable will resolve with no error when done streaming. 
continuable(function (err) {
  if (err) throw err;
  console.log("Done Streaming");

You don't have to store all the steps into variables, so you can simply chain the calls.

Also if you're in an ES6 generator using gen-run, then consuming the continuable is even easier.

var run = require('gen-run');
var fs = require('min-fs');
function* copy(source, dest) {
  yield fs.writeStream(dest)(fs.readStream(source));
run(function* () {
  yield* copy("input.txt", "copy.txt");

chroot(root) -> fs

In addition to the exports object implementing the fs interface with respect to the filesystem root, you can also create a fs instance that is chrooted to some directory.

var fs = require('min-fs')("/home/tim/Code/js-git/.git");
// read the first chunk in the staging area's index. 
fs.readStream("/index")(null, console.log);
