问题
I am learning polymer3.x. I made a dummy polymer element. Now i wanted to know how to publish online and use it in some other framework(eg: angular app).
I completed the requirements as mentioned in https://www.webcomponents.org,
- included License file
- tagged versions
- added README file
But while doing "preview element" i got Error - 12: Missing bower.json. Currently, only Bower is supported. From Polymer version 3, the Polymer team recommends npm instead of Bower.
How to publish my polymer element, so I can use it in another app (like Angular app)?
回答1:
Publishing polymer 3 elements in webcomponents.org is not supported yet, it is on the roadmap
According to Polymer team:
The element catalog at webcomponents.org will be updated to support elements built with modules and distributed via npm.
But you can still just publish your element on npm
See How to Publish & Update a Package on npm
回答2:
You can already add elements published on npm to webcomponents.org, it's just the preview function that doesn't work
Once published on npm, you can just enter the name of your package on the publish page
One "problem" I have run into, is that you have to have a repository field in your package.json, otherwise webcomponents.org won't accept it, something like:
"repository": {
"type": "git",
"url": "https://github.com/your-name/your-package.git"
},
