In Ember.js, project structure is also called directory structure. It contains the following files and directories:

I-app: It contains folders and files for models, components, routes, templates, and styles.

I-bower_components/ bower.json: It is a dependency management tool which is used in Ember CLI to manage front-end plugins and component dependencies.

I-config: It contains the environment.js which controls configure settings for your app.

I-dist: It contains the created output files when we build our app for deployment.

I-node_nodules/package.json: Directory and files are from npm. Npm is the package manager for node.js.

Public: The public directory contains assets such as image and fonts.

Vendor: This directory specifies a location where front-end dependencies that are not managed by Bower go.

Tests/testem.js: Automated tests for our app go in the test folder, and testing is configured in testem.js.

Tmp: Ember CLI temporary files live here.

Ember-cli-build.js: This file describes how Ember CLI should build our app.
