ServerJS/Filesystem API

Requirements/Proposals

• Filesystem API Proposal A
• File API Class hierarchy proposal
• File API name preferences questionnaire
• Summary/Comparison of current File APIs used by JS engines: ServerJS File Object Survey

Prior Art

• Microsoft Scripting.FileSystemObject. Used in classic ASP, WSH, HTAs.
• JavaScript File object proposal (~1998)
• Spidermonkey File object
• Synchronet provides a File Class that was originally inspired by SpiderMonkey's jsfile.c, but has been widely used and enhanced over the years.
• Ejscript's File class is still evolving, but is fairly comprehensive. It supports stackable streams such as BinaryStream, StringStream. It can also do I/O to and from a ByteArray class.
• JSExt.File
• jslibs jsio module
• wxJavascript IO module
• v8cgi has a File and Directory interfaces
• helma has two File apis. One deprecated and one current
• adobe's extendscript has a File constructor.Documentation is difficult to find online.
• generic collection/document resource (java) api (work in process)
• Opera Software's File I/O API for widgets, which will probably be standardized by the W3C Web API Working Group.
