Chrome app create and write to file

由 狂风中的少年 提交于 2019-12-11 09:54:25
问题 I am attempting to use chrome.apps for a program that needs to write multiple separate log files of data. The user then needs to be able to access these these log files outside of the app in their file system for post processing. This will need to be done many times so minimum to no user interaction would be desired for file generation. While this is simple in any native program code, I've been finding this very difficult to do with chrome apps. E.g. can I use chrome apps to create "log_file

Using chrome.runtime.sendmessage to communicate from a webpage to a packaged app

由 非 Y 不嫁゛ 提交于 2019-12-11 08:58:09
问题 I'm trying to communicate from a web page to a packaged app. The idea is to have the web page read a number from a serial device. Because I want to access the serial device, I need a packaged app and can't use an extension. This is pretty similar to Keep Chrome Packaged App running in background? and it seems that Chrome documentation says this is possible. How can I execute the chrome.runtime.sendMessage from a regular web page? When I do so, I get *Uncaught TypeError: Cannot read property
