Installation

To install this package use

npm i filemanageriojs

Use

This package is using fs library under the hood, but its abstracting the functionalities for ease of use. For working with this file you have to import it with

const FileBuilder = require('filemanageriojs')
var file = new FileBuilder()

Then you are all set to read and create files.

const CreatedFile =  file.setPath('path/to/file')
.setName('file')
.setContent("Its me")
.setExtension("ts").create()
CreatedFile.then((res)=>console.log(res)).catch((err)=>console.log(err))

You will get a File object that contains all the neccessary information about the created file. And in this case it looks like this

File {
  name: 'file',
  path: 'path/to/file',
  extension: 'ts',
  size: undefined,
  content: 'Its me',
  allPath: undefined,
  numberOfCharacters: 5
}

To read files you can use

const ReadFile = file.setPath('path/to/file')
.setName('file')
.setExtension('ts')
.read()

This will return a file that is read or an error if it doesn't exist the following file looks like this

File {
  name: 'file',
  path: 'path/to/file',
  extension: 'ts',
  size: undefined,
  content: 'Its me',
  allPath: 'path/to/file/file.ts',
  numberOfCharacters: 5
}

JSON OBJECT MANIPULATION

Working with objects JSON Creating a json file for storing users

var users = [{
    name: "John Doe",
    age: 25,
    email: "[email protected]"
}];
var jsonFile = File.setName("Users").setPath("./users").setExtension("json").setContent(`${JSON.stringify(users)}`).create();

Reading the file and manipulating with the data

var file = File.setName("Users").setPath("./users").setExtension("json").read();
file.then((file) => {
    var content = JSON.parse(file.content);
    content.push({
        name: "Jane Doe",
        age: 24,
        email: ""
    })
    File.updateObject(content); //Hydrate the file with newest data
}).catch((error) => {
    console.error(error);
});

We get the following file

[{
    "name": "John Doe",
    "age": 25,
    "email": "[email protected]"
},
{
    "name": "Jane Doe",
    "age": 24,
    "email": ""
}]

For deleting use.

var file = File.setName("Users").setPath("./users").setExtension("json").read();
file.then((file) => {
    var content = JSON.parse(file.content);
    content.pop()
    File.updateObject(content); //Hydrate the file with newest data

}).catch((error) => {
    console.error(error);
});
// OR
File.deleteObjectAtIndex(1) 

Using pop will delete the last element in the array while deleteObjectAtIndex(index) will delete the element at index.
