FILE-MANIPULATOR

Easy File operations library

1. ways of using

• for file system operation 🤖
• node js fs wrapper for CRUD to files and folders ✅
• create your custom CLI 🎉 ( fs / nodejs / react-native / flutter / ember/eth... )
• easy and readable documentation 🍗
• high-level wrapper for every-level projects 🍎
• good supporting 🥽
• except error handling and using boolean operations methods result ✅
• UPD: support js and ts already ✅ ✅ ✅

install

yarn add file-manipulator

or

npm i file-manipulator

2. one`s principe for each method

every operation need to:

• file
  • file name
  • file extension
  • file folder path
  • operation (CRUD)
• folder
  • folder name
  • folder path
  • operation (CRUD)

3. example of using

import fileManipulator from 'file-manipulator'


const start = async () => {
  //create file
  const isCreatedFile = await fileManipulator.create.file({
    name: 'example-file',
    ext: 'txt',
    path: './',
    content: 'Hello wold 🎉',
    replaceExisting: true
  })
  console.log({isCreatedFile})

  //create folder
  const isCreatedFolder = await fileManipulator.create.folder({
    name: 'example-folder',
    path: './',
    replaceExisting: true
  })
  console.log({isCreatedFolder})

  //copy file to folder
  const isCopiedFile = await fileManipulator.copy.file({
    name: 'example-file',
    ext: 'txt',
    from: './',
    to: './example-folder',
    replaceExisting: true
  })
  console.log({isCopiedFile})

  //move example file to example folder
  const isMovedFile = await fileManipulator.move.file({
    name: 'example-file',
    ext: 'txt',
    from: './',
    to: './example-folder',
    renameTo: 'example-file-1',
  })
  console.log({isMovedFile})

  //delete excess file
  const isDeletedFile = await fileManipulator.delete.file({
    name: 'example-file',
    ext: 'txt',
    path: './example-folder',
  })
  console.log({isDeletedFile})

  //edit file name
  const isRenamedFile = await fileManipulator.update.file({
    name: 'example-file-1',
    ext: 'txt',
    renameTo: 'example-file',
    path: './example-folder'
  })
  console.log({isRenamedFile})

  //replace file inner
  const isReplacedInnerText = await fileManipulator.update.file({
    name: 'example-file',
    ext: 'txt',
    path: './example-folder',
    stringFrom: 'Hello ', //string or regexp
    stringTo: 'Wow 🎉',
  })
  console.log({isReplacedInnerText})

  //replace file inner text by coordinates
  const isEditedInnerText = await fileManipulator.update.file({
    name: 'example-file',
    ext: 'txt',
    path: './example-folder',
    lineParams: {line: 0, space: 6, len: 7}, //replace from row 0, col 6, to row 0, col 13, to  "stringTo" value
    stringTo: 'Wow 🎉',
  })
  console.log({isEditedInnerText})
}
