objectify-directory

Maps directory and it's content to a tree of objects with inner navigation.
Typed for Typescript

Why?

Sometimes it might be usefull to map directory, it's subdirectories and their files to tree of JS objects.

Getting started

npm i --save objectify-directory

// ES6
import parseDirectory from 'objectify-directory';
// CommonJS
const parseDirectory = require('objectify-directory').default;

// then
parseDirectory(path.resolve(__dirname,'./folderToMap')).then(root => {

});
// await
let root = parseDirectory(path.resolve(__dirname,'./folderToMap'));

When JSON.stringify() is called a simplified version of the tree is returned in order to deal with circular references.

Options

• loadContent: boolean loads binary of the file as property of TreeFile object
• calculateSize: boolean calculates byte size of the file as property of TreeFile object
• contentInJson: boolean includes Buffer.toString() in content of TreeFile when JSON.strigify() is called, loadContent needs to be set true

Types

TreeElement

Common ancestor to TreeFolder and TreeFile. Holds methods available to both types.

Properties

• name: string name of the directory of file (without extension)
• parent: TreeElement reference to parent directory (always directory as only dirs can have children)
• children: Map<string, TreeElement> collection of children elements, should be accessed only via .goto method

Methods

• fullPath(): string returns full path to the element from the root of the drive
• relativePath(): string return relative path from root
• goto(path: string): TreeElement navigates through the tree, accepts common path pattern (eg: "../siblingFolder", "./childFolder", "./child.file")

TreeFolder

Object representation of folder.

TreeFile

Object representation of file

Properties

• extension: string extension of the file
• size: number byte size of the file if option set true
• content: Buffer content of the file if option set true

Methods

• getSize(): number calculates the byte size of the file or returns size proeprty if set
• getContent(): Buffer reads content of the file, or return content property if set
