Contribution

This repository is an open-source work-in-progress and we welcome contributions.

We regularly deploy the latest code containing all accepted contributions online as part of the Mat3ra.com platform, so contributors will see their code in action there.

See ESSE for additional context regarding the data schemas used here.

Useful commands for development:

# run linter without persistence
npm run lint

# run linter and save edits
npm run lint:fix

# compile the library
npm run transpile

# run tests
npm run test

Using Linter

Linter setup will prevent committing files that don't adhere to the code standard. It will attempt to fix what it can automatically prior to the commit in order to reduce diff noise. This can lead to "unexpected" behavior where a file that is staged for commit is not identical to the file that actually gets committed. This happens in the lint-staged directive of the package.json file (by using a husky pre-commit hook). For example, if you add extra whitespace to a file, stage it, and try to commit it, you will see the following:

➜  repo-js git:(feature/cool-feature) ✗ git commit -m "Awesome feature works great"
✔ Preparing...
✔ Running tasks...
✖ Prevented an empty git commit!
✔ Reverting to original state because of errors...
✔ Cleaning up...

  ⚠ lint-staged prevented an empty git commit.
  Use the --allow-empty option to continue, or check your task configuration

husky - pre-commit hook exited with code 1 (error)

The staged change may remain but will not have been committed. Then it will look like you still have a staged change to commit, but the pre-commit hook will not actually commit it for you, quite frustrating! Styling can be applied manually and fixed by running:

npm run lint:fix

In which case, you may need to then add the linter edits to your staging, which in the example above, puts the file back to identical with the base branch, resulting in no staged changes whatsoever.

ProDe

TheProDe package is central to many other entities in the Mat3ra workflow ecosystem, where ProDe houses entity definitions for:

Property - the basic definition of a property
- properties can be of the following types:
  - scalar non_scalar tensor object
- specific properties are implemented by subclassing Property
