filer.js is a well-tested JavaScript wrapper library for the HTML5 Filesystem API, which lets web applications read and write files in a sandboxed filesystem. Its API reuses familiar UNIX commands (cp, mv, ls) to make browser file I/O more approachable for developers.

Use cases

• read and write files in a sandboxed browser filesystem
• list directory contents in a web app using ls-like API
• copy and move files in the browser with cp and mv commands
• manage persistent or temporary storage for a Chrome web app
• simplify the verbose HTML5 Filesystem API with familiar commands

When to choose

• you are building a Chrome-only web app that needs sandboxed file I/O
• you prefer a UNIX-style API (cp, mv, ls) over the raw HTML5 Filesystem API
• you want a well-tested wrapper with a demo and documentation

When to avoid

• you need cross-browser support, since the HTML5 Filesystem API only works in Chrome
• you need actively maintained software, as the project has not seen releases since 2019
• you need server-side or Node.js file system access
