Description

rsyncjs provides a similar API to rsync, but in pure js.

With some additional features, such as splitting large files and quota throttling support.

Todo: Convert to TS 4.5 and export ESM

Based on sync-directory by @gh:hoperyy

Examples

Node

import { async as rsync } from 'rsyncjs'

const sleep = (s) => new Promise((p) => setTimeout(p, s * 1000))

console.time('rsync')

const main = async () => {
  await rsync(srcDir, targetDir, {
    async afterEachSync({ type, relativePath }) {
      console.log(type, relativePath)
      await sleep(1.5) // delay 1.5s after one file was synced
    }
  })
  console.timeEnd('rsync')
}
main()

Shell

# yarn add global rsyncjs
# npx -y rsyncjs <from> <to> [options]
npm install -g rsyncjs
rsyncjs <from> <to> [options]

Synchronous use via deasync

var rsyncjsCJS = require('rsyncjs')
var deasync = require('deasync')
var rsync = deasync(rsyncjsCJS.async)

Browser use with FileSystem API

Not tested... but willing to support it.

API

| import | Returns | Syntax | Blocks thread? | | ------ | --------- | ------------------------- | -------------- | | async | Promise | async / await, promises | No |

Params

| name | description | type | values | default | | ----------------------- | ------------------------------------------------ | ------------------------------------------------- | ------------- | ----------------------------------- | | srcDir | src directory | String | absolute path | - | | targetDir | target directory | String | absolute path | - | | config.deleteOrphaned | Delete other files in targetDir | Boolean | - | true | | config.afterEachSync | callback function when every file synced | Function | - | blank function | | config.exclude | files that should not sync to target directory. | RegExp / String / Array (item is RegExp / String) | - | null | | config.forceSync | some files must be synced even though 'excluded' | Function | - | (file) => { return false } | | config.filter | function to filter.

• afterEachSync

  await rsync(srcDir, targetDir, {
    async afterEachSync({ type, relativePath }) {
      // type: init:hardlink / init:copy / add / change / unlink / unlinkDir
      // - init type: "init:copy"
      // - watch type: "add" / "change" / "unlink" / "unlinkDir"
      // relativePath: relative file path
    }
  })

• type

  • copy

    rsync(srcDir, targetDir, {
      type: 'copy'
    })

• exclude

  exclude node_modules

  • String

    rsync(srcDir, targetDir, {
      exclude: 'node_modules'
    })

  • RegExp

    rsync(srcDir, targetDir, {
      exclude: /node\_modules/
    })

  • Array

    rsync(srcDir, targetDir, {
      exclude: [/node\_modules/]
    })

    rsync(srcDir, targetDir, {
      exclude: ['node_modules']
    })

• forceSync

  rsync(srcDir, targetDir, {
    exclude: 'node_modules',
    forceSync(file) {
      // all files in "node_modules" will be synced event though "exclude" is configed
      return /node_modules/.test(file)
