Basic Information

This page allows you to edit the existing project (twit-counter). The edited project will replace the existing entry in the IoT Projects page. If you want to add a new entry based on the project, please fork from it instead.

* Photo URLs that end with any one of .jpg, .jpeg, .png or that are uploaded to the Gyazo web service in the PNG format (e.g.https://gyazo.com/hogehoge) are supported.

{ "dependencies": { "twitter": "latest" } }

* Node.js entry point main: index.js and dependencies to the npm module dependencies: { f3js: (略) } will be automatically added and thus do not need to be in this form.
