  +**Rule of thumb** is: all modules go into `./package.json` except native modules, or modules with native dependencies or peer dependencies. Native modules, or packages with native dependencies should go into `./app/package.json`.
  1. If the module is native to a platform (like node-postgres), 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`.
