REserve/fs

File system mapper for REserve. It makes Node.js' fs APIs available in the browser.

Usage

• In the mapping :

{
  "handlers": {
    "fs": "reserve-fs"
  },
  "mappings": [{
    "match": "\\/fs",
    "fs": "./"
  }]
}

• In the HTML page :

<script src='/fs'></script>

• In JavaScript :

fs.readdirAsync('folder')
  .then(names => names.forEach(async name => {
    const stat = await fs.statAsync('folder/' + name)
    console.log(name, stat.size, stat.ctime, stat.mtime)
  }))

Options

Option	Default Value	Explanation
client-name	'fs'	Name of the member added to the browser window
read-only	false	Forbids write methods if true

All APIs are restricted to the scope of the path configured in the mapping. Any attempt to read or write elsewhere will lead to a 403 error.

Supported APIs

The following APIs are supported. A promisified version of each method is provided under the same name suffixed with Async (for instance: fs.readdirAsync).

• read-only
  • fs.readdir
  • fs.readFile: the returned data is converted to text
  • fs.stat
• read/write
  • fs.mkdir
  • fs.rmdir
  • fs.unlink
  • fs.writeFile: file must be a file name, data is a string
