FileSystem JS

This is a JavaScript wrapper that provides a promise interface for working with the Chrome Browser FileSystem API. It is built with the aim of making it very easy to use. Hence, promises, rather than the default callbacks that the Native Implementations use.

Available Methods

• Request Permission

  You can request permission to use the File System on your Web Application with

FileSystem.request()
            .then(function (fs) {
                console.log(fs) //[fs] is a FileSystem object
            })
            .catch(function (err) { 
                console.error(err)
            })

• Create New File

  You can create a new file in the file system allocated to your application

FileSystem.createFile("log.txt")
            .then(function (fileEntry) { 
                console.log(fileEntry) //manipulate the new file
            })
            .catch(function (err) { 
                console.error(err) 
            })

• Read File

  You can read a file already existing in the file system allocated to your application

FileSystem.readFile("log.txt")
            .then(function (fileEntry) { 
                console.log(fileEntry) //do stuff with the fileEntry
            })
            .catch(function (err) { 
                console.error(err) 
            })

• Read File as Text

  You can read text from a file already existing in the file system allocated to your application

FileSystem.readFileText("log.txt")
            .then(function (textContent) { 
                console.log(textContent) //do stuff with the textContent
            })
            .catch(function (err) { 
                console.error(err) 
            })

• Write Stuff to a File

  You can read text from a file already existing in the file system allocated to your application

FileSystem.writeFile("log.txt", new Blob(["Hello World"], { type: "text/plain" }))
            .then(function (fileEntry) { 
                console.log(fileEntry) //do stuff with the fileEntry
            })
            .catch(function (err) { 
                console.error(err) 
            })

Contributions

This was built to aid in a quick pet project, so there are a lot more methods people might need that are not available. Quick examples from the top of my head are:

• Rename File
• Delete File
• Move File
• Copy and Paste File
• All other stuff with Directories
