Used by packaged apps
to specify what types of files the app can handle. An app can have multiple file_handlers
, with each one having an identifier, a list of MIME types and/or a list of file extensions that can be handled, and
a title. Here's an example of specifying file handlers:
"file_handlers": { "text": { "types": [ "text/*" ], "title": "Text editor" }, "image": { "types": [ "image/png", "image/jpeg" ], "extensions": [ "tiff" ], "title": "Image editor" }, "any": { "extensions": [ "*" ], "title": "Any file type editor" } }
To handle files, apps also need to declare the $ref:fileSystem permission. Apps can then be passed files in the $ref:app.runtime.onLaunched event - either from the system file manager (currently supported on ChromeOS only) or by providing a path on the command line.
