This is just an adaptation of the start project for Polymer 3.0 with support for TypeScript, and it is shamelessly adapted from here. Use this to get a feel for TypeScript Decorators for Polymer, and the basic tsconfig.json
.
Please use the latest version of Chrome or Safari to view the app. It uses native dynamic imports. Also, use lit-html plugin for VS Code to get some nice syntax highlighting on template blocks.
npm install -g polymer-cli
git clone https://github.com/twitchax/start-polymer3-typescript.git
