Convert to Graphql

[titaniumbones]

Canvas has an "experimental" graphql endpoint which is dramatically faster & allows much more complex queries. Documentation is much sparser than in the REST API, and it's uncleatr which parts of the API are supported, but, a very quick investigation at the U of T online test point shows that it should, e.g., be possible to submit all student marks for a given assignment in a single query, a dramatic speedup. Submissions are also accessible this way, though since they are stored off-site on AWS the speedup may not be as noticeable, and the access is buried pretty deep i n the assignments.

Not an urgent need, but a significant improvement & worth following up on. Here are some sample queries from the API:

All Courses

query MyQuery {
  allCourses {
    id
    courseCode
  }
}

All Assignments

query MyQuery {
  course(id: "Q291cnNlLTY0NzA2") {
    name
    term {
      id
    }
    courseCode
    assignmentsConnection {
      edges {
        node {
          name
          hasSubmittedSubmissions
          submissionsConnection {
            edges {
              node {
                id
                body
                attachments {
                  updatedAt
                  id
                }
              }
            }
            nodes {
              id
            }
          }
        }
      }
    }
  }
}

Clumsy all submissions

query MyQuery {
  course(id: "Q291cnNlLTY0NzA2") {
    name
    term {
      id
    }
    courseCode
    assignmentsConnection {
      edges {
        node {
        
          name
          hasSubmittedSubmissions
          submissionsConnection {
            edges {
              node {
                id
              }
            }
            nodes {
              id
            }
          }
        }
      }
    }
  }
}

Submissions Ids

query MyQuery {
  course(id: "Q291cnNlLTY0NzA2") {
    name
    term {
      id
    }
    courseCode
    assignmentsConnection {
      edges {
        node {
          name
          hasSubmittedSubmissions
          submissionsConnection {
            edges {
              node {
                id
                body
                attachments {
                  updatedAt
                  id
                }
              }
            }
            nodes {
              id
            }
          }
        }
      }
    }
