Make Ionic app appear in “Share” list and receive data

阅读更多关于 Make Ionic app appear in “Share” list and receive data

That I can do using the cordova-custom-config plugin, I think. I would then have to handle that intent somehow

阅读更多关于 Ionic2/Angular2 - Read a custom config file

问题 I\'m working on an ionic2 project and I need to create a new custom JSON config file. I found some tutorials to create one and access it through http.get but I think it\'s weird to call it through a get request. I want it in the root folder (where all the config JSONs are) and I open/read the file directly. I don\'t know if it\'s possible, or even recommended ? This is why I\'m posting here to have some opinions and solutions :) Thanks 回答1: Personally I don't like the read the config.json
