  **Rule of thumb** is: all modules go into `./package.json` except native modules. Native modules go into `./app/package.json`.
  -1. If the module is native to a platform (like node-postgres) or otherwise should be included with the published package (i.e. bcrypt, openbci), it should be listed under `dependencies` in `./app/package.json`.

  2. If a module is `import`ed by another module, include it in `dependencies` in `./package.json`. See [this ESLint rule](https://github.com/benmosher/eslint-plugin-import/blob/master/docs/rules/no-extraneous-dependencies.md). Examples of such modules are `material-ui`, `redux-form`, and `moment`.
  3. Otherwise, modules used for building, testing and debugging should be included in `devDependencies` in `./package.json`.
