The website frontend for autograder.io, implemented using Vue and Typescript. For information about contributing to Autograder.io, see our contributing guide.

Follow the dev stack setup tutorial for the autograder-full-stack repo.

The unit tests currently support Node.js version 12 (newer versions may work too). You can install this version with NVM by running:

nvm install 12

To run the unit tests (with coverage):

npm test

In addition to the items listed here, all source code must follow our Typescript/Vue coding standards.

Run npm run build to check for some style issues using TSLint. All code must be free of TSLint errors. This command should also be treated as the single source of truth for type checking, as different editor plugins have various shortcomings.

• HTML/CSS
  • Prefer classes to id's unless you can guarantee that only one element with the id will exist at a time.
    • Prefer using nested or otherwise more specific CSS class selectors when you need to override some imported style.
  • Use skewer-case for class and id names.
  • Avoid adding a class or id solely for the purpose of being able to select an element in test cases. Prefer to use a data-testid=xxx attribute and wrapper.find('[data-testid=xxx]') for this purpose. Use snake_case for data-testid values.
• Copying objects in components
  • If a component needs to modify the members of an object passed as input via @Prop, make a deep copy of that object and modify the copy.
  • Similarly, if a component does NOT need to modify members of an @Prop input, do NOT copy the object.
  • When receiving a new or updated object from an observer update_ function, make a deep copy of the object.
  • Use the deep_copy function in src/utils.ts to make deep copies of class instances that have a constructor and/or member functions. For other objects, JSON.parse(JSON.stringify(...)) is the preferred approach.
