File API: Directories and System API

Introduction

Most servers need a FileSystem API Even if not implemented everywhere one is candidate for client-side as W3C Recommendation

This specification propose synchronous and asynchronous APIs.

'7. The synchronous filesystem interface

-> http://www.w3.org/TR/file-system-api/#the-synchronous-filesystem-interface

Synchronous API are defined as usable only in Worker contexts.

4.4 Obtaining access to file system entry points

There are several ways in which a file system entry point can be obtained. Not all user agents may in fact implement all of them. However, in order to avoid blocking UI actions while waiting on filesystem IO, we define only an asynchronous interface for Window, and restrict the synchronous API to the Worker context defined in [WEBWORKERS-ED].

Contacts

We are looking for representatives of this HTML5 API to discuss of potentially needed updates to consider server-side implementations

Debate

• The client-side concept of sandbox is interesting on server-side when considering security in shared hosting environments

SSJS Implementations

Wakanda

Wakanda implements the synchronous version of the FileSystem API:
