Canvas Grade Uploader

A simple tool to handle grade uploading to Canvas, a learning management system.

Installation

The grade uploader works well as a command line tool. If you're using it this way be sure to use the -g option:

npm install -g canvas-grade-uploader

Usage

There are two use cases:

1. Command line tool:

   grade-uploader [leave blank for short help]
   usage: grade-uploader [-h] [-v] -c COURSE_ID -a ASSIGNMENT_ID -f FILE [-u URL] -t
             TOKEN [-uid {"",sis_login_id,sis_user_id}]
   

   grade-uploader -t [token] -c 1268501 -a 7148451 -f ~/Desktop/Midterm_scores.csv
   

   • When using the command line, you can optionally define CANVAS_TOKEN in your environment. This will be used if no -t option is provided.

2. As a module:

   var postGrades = require('canvas-grade-uploader');
   
   postGrades(options, data, callback); // See below for options
   

NOTE The module interface is currently a work in progress. Breaking changes to this interface will be semver-minor, at least until it's fully stable.

Configuration

The grade uploader uploads grades to a specific Canvas assignment. To do this a few details are required. The command line help will walk you through most of them.

Canvas assignment and course IDs are easily obtained from the URL of the assignments page.

For example:

https://bcourses.berkeley.edu/courses/1268501/assignments/7148451

• URL: https://bcourses.berkeley.edu/
• Course ID: 1268501
• Assignment ID: 7148451

Getting a Canvas Token

Canvas authenticates users with Oauth Tokens. You can generate a token for yourself by visiting your personal settings page. There is Canvas documentation about generating your own token.

The short version is: Visit this page. https:/<canvas-instance>/profile/settings

CSV Format

This tool was built to speed up working with Gradescope

The CSV file requires the following values:

• "SID" -- This is the unique user ID for each student.
• "Total Score" -- This is the score that each user will receive.
• Optional "Name" -- The name column currently isn't used, but might be for debugging in the future. (Really, it's much much nicer to deal with names over IDs when possible.)

Default Values

Currently, there are a couple default values which as "Berkeley-specific". If this tool gets enough use, I'll gladly change them…

• URL, -u defaults to: https://bcourses.berkeley.edu
• User ID format, -sid defaults to: sis_user_id. This parameter controls how Canvas interprets user IDs. See this.

(In the future, I'd consider supporting some means of having user-default parameters, so please submit a PR if you'd like!)

Options and Callback Formats

Using this as a module requires 3 parameters:

• options: A JS object, with keys that mirror the command line arguments. Note: in this form, the only defaults that are applied are the CSV column names. The file parameter is not required.

   {
     course_id: '1268501',
     assignment_id: '7148451',
     url: 'https://bcourses.berkeley.edu/',
     token: '<token>',
     user_id_format: 'sis_user_id'
   }
  

• data: This is the CSV data, as a string.
• callback: This is called with a string, updating the progress of uploading grades. Note that it will be called quite a few times in the process uploading grades.
  • WARNING This will be updated to have a signature like (err, resp) very soon.
