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

• 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)
  }))

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.

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
