localwatch

localwatch

Watch a directory and get a diff of changes

npm install localwatch

Usage

const Localwatch = require('localwatch')

 // watch a dir
const watch = new Localwatch('./my/dir')

// watch is a readable stream

for await (const diff of watch) {
  // diff is the next batch of changes
  // [{ type: update|delete, filename }, ...]
}

API

stream = new Localwatch(dir, [options])

Make a watch stream.

Options include

{
  // function that returns true if it should watch it
  // defaults to ignoring .git and corestores
  filter (filename, stream) { ... },
  // use relative paths in the diff
  relative: false,
  // include hidden files (.something)
  hidden: false,
  // wait for the watched folder to be idle for 100ms
  // before triggering the batch after a change has happened.
  // disable this if you the watcher to be fully interactive
  settle: true
}

The stream yields diffs which look like this

[{
  type: 'update' || 'delete',
  filename
}, {
  ...
}]

The diff reflects the changes that happens since the last yield.

Localwatch.defaultFilter(filename, [stream])

Does the default filter. Useful if you wanna expand on the defaults.
