Dashing Trello widget

README.md

Description

A Dashing widget for displaying the number of items of lists on a Trello board.

See a live demo here.

Usage

Setup the following environment variables:

• TRELLO_DEVELOPER_KEY
• TRELLO_MEMBER_TOKEN
• TRELLO_BOARD_NAME: name of the Trello board you wish to monitor
• TRELLO_LIST_NAMES: comma-separated list of the names of the Trello lists on the board that you wish to monitor

Get your TRELLO_DEVELOPER_KEY from here.

Visit this URL, with the following GET parameters:

• key: the TRELLO_DEVELOPER_KEY you got in step 1.
• response_type: "token"
• expiration: "never" if you don't want your token to ever expire. If you leave this blank, your generated token will expire after 30 days

You should see a page asking you to authorize your Trello application. Click "allow" and you should see a second page with a long alphanumeric string. This is your TRELLO_MEMBER_TOKEN.
