How to deploy a Dart Polymer app to Javascript using dart2js

由 南楼画角 提交于 2019-12-21 19:46:23
问题 I got a problem while deploying Dart code using Polymer to Javascript. I've created a polymer application with DartEditor and made a simple example. This example works in Dartium but when I try to build it as a Polymer App (in Javascript) and launch it, the app fails. How am I supposed to convert a Dart Polymer app to Javascript ? Here's the example code I made that fails : example.html : <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Example</title> <link rel="import" href=

how to enable --enable-experimental-mirrors in dart build?

由 瘦欲@ 提交于 2019-12-19 08:08:17
问题 My build of my projects are failing because they rely on mirrors and dart build out put tells me to use --enable-experimental-mirrors to try to use mirrors in dart2js code as it is. so if I run pub build --enable-experimental-mirrors all I get is Could not find an option named "enable-experimental-mirrors" . Any hints much appreciated. 回答1: I haven't tried this myself yet but maybe you can pass it as a command line option in the transformer config transformers: - $dart2js: commandLineOptions:

问题 I am doing polymer dart. Everything works fine with dart vm but when I try to deploy it, it fails (compilation was okay.) When I run the built js version.
