A tiny wrapper around for added, removed and changed events


There is no such thing as and this is a wrapper around it. Another one. Yep, there are lots of wrappers and I tried a couple for my project but found that they were all buggy in their own idiosyncratic ways. I needed one that was buggy in a specific way, so I coded up tiny-wrapper.

var tiny = require('../.')
  , fs = require('fs')
  , rimraf = require('rimraf')
  , path = require('path')
var somedir = "somedir"
var watcher = tiny(somedir, ["test", "total"])
watcher.on("added", function (file) {
  console.log("EXAMPLE: added", file)
watcher.on("removed", function (file) {
  console.log("EXAMPLE: removed", file)
watcher.on("changed", function (file) {
  console.log("EXAMPLE: changed", file)
fs.writeFileSync(path.join(somedir, "test"), "data")
fs.unlinkSync(path.join(somedir, "test"))
fs.writeFileSync(path.join(somedir, "total"), "data")
fs.writeFileSync(path.join(somedir, "total"), "new data")
fs.writeFileSync(path.join(somedir, "tonnes"), "data")
 * Setting watcher kill should stop the remove event
 * when total is removed with rimraf
setTimeout( function () {
  rimraf(somedir, function (err) {
    if (err) throw err
}, 1000)

which produces

EXAMPLE: added test
EXAMPLE: removed test
EXAMPLE: added total
EXAMPLE: changed total

The main object is a function that produces watchers for a specific directory an optional set of files.

var watcher = tiny("path/to/dir" [, ["list", "of", "files"]])

Three events, added, removed and changed are supported. The callback returns the filename.

Cycle through all the files being monitored by the tiny-watcher instance and emit event events for each one. Useful for on-startup tasks.

Calls the base fs method watcher.close()
