With this script, when i load my app ionic serve -l i can see the error throw in console. It’s the only page in the entire app who throw it, and it’s the rootpage, at initialization.
Where do i messed up?
By the way, since Tracker is an es6 module i put target: es6 in tsconfig.json, is there a way to put es5 and force the compilation of the es6 module before webpack compact the main.js?
