Deploying an Ember.js App

Ember.js is a powerful, opinionated JavaScript framework designed for building ambitious web applications with a strong focus on developer productivity and code maintainability. It features a robust CLI, convention-over-configuration philosophy, two-way data binding, a comprehensive router, built-in state management, and a large ecosystem of add-ons. Ember.js is ideal for building scalable single-page applications (SPAs) that require sophisticated client-side logic, complex data relationships, and long-term maintainability.

This comprehensive guide walks through deploying an Ember.js application to Klutch.sh using either Nixpacks (automatic zero-configuration deployment) or a Dockerfile (manual container control). You’ll learn how to scaffold an Ember project, create components and services, structure routes and data models, configure environment variables, implement security best practices, set up monitoring, deploy custom domains, and troubleshoot common issues. By the end of this guide, you’ll have a production-ready Ember.js application running on Klutch.sh’s global infrastructure with automatic HTTPS and optimized performance.

Prerequisites

  • Node.js & npm (version 16+) – Download Node.js
  • Ember CLI installed globally via npm
  • Git installed locally and a GitHub account (Klutch.sh uses GitHub as the only git source)
  • Klutch.sh account with access to the dashboard at klutch.sh/app
  • Basic knowledge of JavaScript, Handlebars templates, and the Node.js ecosystem

Getting Started: Create an Ember.js App

1. Install Ember CLI

Install the Ember CLI globally:

Terminal window
npm install -g ember-cli

2. Create a New Ember Project

Create a new Ember.js application:

Terminal window
ember new my-ember-app
cd my-ember-app
npm install

3. Project Structure

A typical Ember.js project structure looks like:

my-ember-app/
├── app/
│   ├── components/
│   │   ├── article-list.hbs
│   │   ├── article-list.js
│   │   ├── article-item.hbs
│   │   └── article-item.js
│   ├── controllers/
│   │   └── articles.js
│   ├── models/
│   │   ├── article.js
│   │   └── user.js
│   ├── routes/
│   │   ├── articles.js
│   │   ├── articles/detail.js
│   │   └── index.js
│   ├── services/
│   │   ├── api.js
│   │   └── auth.js
│   ├── styles/
│   │   └── app.css
│   ├── templates/
│   │   ├── application.hbs
│   │   ├── articles.hbs
│   │   ├── articles/detail.hbs
│   │   └── index.hbs
│   └── app.js
├── config/
│   └── environment.js
├── public/
├── tests/
├── ember-cli-build.js
├── package.json
├── Dockerfile
└── README.md

4. Run the Development Server

Start the Ember development server:

Terminal window
ember serve

Navigate to http://localhost:4200 in your browser. The app will automatically reload as you make changes.

5. Create a Data Model

Create an Ember data model for articles:

app/models/article.js
import Model, { attr } from '@ember-data/model';


export default class ArticleModel extends Model {
  @attr title;
  @attr content;
  @attr author;
  @attr('date') createdAt;
  @attr('date') updatedAt;


  get shortContent() {
    return this.content.substring(0, 100) + '...';
  }
}

6. Create a Service

Create a service for API communication:

app/services/api.js
import Service from '@ember/service';
import { service } from '@ember/service';
import fetch from 'fetch';


export default class ApiService extends Service {
  @service store;


  constructor() {
    super(...arguments);
    this.baseURL = process.env.API_URL || 'http://localhost:3000/api';
  }


  async getArticles() {
    try {
      const response = await fetch(`${this.baseURL}/articles`);
      if (!response.ok) {
        throw new Error(`Failed to fetch articles: ${response.statusText}`);
      }
      return await response.json();
    } catch (error) {
      console.error('Error fetching articles:', error);
      throw error;
    }
  }


  async getArticle(id) {
    try {
      const response = await fetch(`${this.baseURL}/articles/${id}`);
      if (!response.ok) {
        throw new Error(`Failed to fetch article: ${response.statusText}`);
      }
      return await response.json();
    } catch (error) {
      console.error('Error fetching article:', error);
      throw error;
    }
  }


  async createArticle(data) {
    try {
      const response = await fetch(`${this.baseURL}/articles`, {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
          'Authorization': `Bearer ${this.getToken()}`
        },
        body: JSON.stringify(data)
      });
      if (!response.ok) {
        throw new Error(`Failed to create article: ${response.statusText}`);
      }
      return await response.json();
    } catch (error) {
      console.error('Error creating article:', error);
      throw error;
    }
  }


  async updateArticle(id, data) {
    try {
      const response = await fetch(`${this.baseURL}/articles/${id}`, {
        method: 'PUT',
        headers: {
          'Content-Type': 'application/json',
          'Authorization': `Bearer ${this.getToken()}`
        },
        body: JSON.stringify(data)
      });
      if (!response.ok) {
        throw new Error(`Failed to update article: ${response.statusText}`);
      }
      return await response.json();
    } catch (error) {
      console.error('Error updating article:', error);
      throw error;
    }
  }


  async deleteArticle(id) {
    try {
      const response = await fetch(`${this.baseURL}/articles/${id}`, {
        method: 'DELETE',
        headers: {
          'Authorization': `Bearer ${this.getToken()}`
        }
      });
      if (!response.ok) {
        throw new Error(`Failed to delete article: ${response.statusText}`);
      }
    } catch (error) {
      console.error('Error deleting article:', error);
      throw error;
    }
  }


  getToken() {
    return localStorage.getItem('authToken') || '';
  }
}

7. Create a Route

Create a route for articles:

app/routes/articles.js
import Route from '@ember/routing/route';
import { service } from '@ember/service';


export default class ArticlesRoute extends Route {
  @service api;
  @service store;


  async model() {
    try {
      const articles = await this.api.getArticles();
      return this.store.push({
        data: articles.map(article => ({
          type: 'article',
          id: article.id,
          attributes: article
        }))
      });
    } catch (error) {
      console.error('Error loading articles:', error);
      return [];
    }
  }
}

8. Create a Component

Create a reusable article list component:

app/components/article-list.js
import Component from '@glimmer/component';
import { action } from '@ember/object';
import { service } from '@ember/service';


export default class ArticleListComponent extends Component {
  @service api;
  @service router;


  @action
  async deleteArticle(articleId) {
    if (confirm('Are you sure you want to delete this article?')) {
      try {
        await this.api.deleteArticle(articleId);
        // Refresh articles list
        this.router.transitionTo('articles');
      } catch (error) {
        console.error('Error deleting article:', error);
      }
    }
  }


  @action
  editArticle(articleId) {
    this.router.transitionTo('articles.edit', articleId);
  }


  @action
  viewArticle(articleId) {
    this.router.transitionTo('articles.detail', articleId);
  }
}

Create the template:

{{! app/templates/components/article-list.hbs }}
<div class="article-list">
  <h2>Articles</h2>


  {{#if (gt @articles.length 0)}}
    <div class="articles-grid">
      {{#each @articles as |article|}}
        <div class="article-card">
          <h3>{{article.title}}</h3>
          <p class="excerpt">{{article.shortContent}}</p>
          <div class="metadata">
            <span class="author">By {{article.author}}</span>
            <span class="date">{{format-date article.createdAt}}</span>
          </div>
          <div class="actions">
            <button {{on "click" (fn this.viewArticle article.id)}} class="btn btn-primary">
              Read More
            </button>
            <button {{on "click" (fn this.editArticle article.id)}} class="btn btn-secondary">
              Edit
            </button>
            <button {{on "click" (fn this.deleteArticle article.id)}} class="btn btn-danger">
              Delete
            </button>
          </div>
        </div>
      {{/each}}
    </div>
  {{else}}
    <p class="no-articles">No articles found</p>
  {{/if}}
</div>

9. Router Configuration

Set up your routing in app/router.js:

import EmberRouter from '@ember/routing/router';
import config from 'my-ember-app/config/environment';


export default class Router extends EmberRouter {
  location = config.locationType;
  rootURL = config.rootURL;
}


Router.map(function () {
  this.route('articles', function () {
    this.route('detail', { path: ':id' });
    this.route('edit', { path: ':id/edit' });
    this.route('new');
  });
  this.route('about');
  this.route('contact');
});

10. Application Template

Set up your main application template:

{{! app/templates/application.hbs }}
<nav class="navbar">
  <div class="navbar-brand">
    <h1>My Ember App</h1>
  </div>
  <ul class="navbar-nav">
    <li>{{#link-to "index"}}Home{{/link-to}}</li>
    <li>{{#link-to "articles"}}Articles{{/link-to}}</li>
    <li>{{#link-to "about"}}About{{/link-to}}</li>
    <li>{{#link-to "contact"}}Contact{{/link-to}}</li>
  </ul>
</nav>


<main class="container">
  {{outlet}}
</main>


<footer class="footer">
  <p>&copy; 2024 My Ember App. All rights reserved.</p>
</footer>

11. Environment Configuration

Configure your app in config/environment.js:

'use strict';


module.exports = function (environment) {
  let ENV = {
    modulePrefix: 'my-ember-app',
    environment,
    rootURL: '/',
    locationType: 'history',
    EmberENV: {
      FEATURES: {
        // feature flags here
      },
      EXTEND_PROTOTYPES: {
        Date: false,
      },
    },


    APP: {
      // API configuration
      apiURL: process.env.API_URL || 'http://localhost:3000/api',
      siteName: process.env.SITE_NAME || 'My Ember App'
    },
  };


  if (environment === 'development') {
    // Development-specific configuration
    ENV.APP.LOG_RESOLVER = true;
    ENV.APP.LOG_ACTIVE_GENERATION = true;
    ENV.APP.LOG_TRANSITIONS = true;
    ENV.APP.LOG_TRANSITIONS_INTERNAL = true;
  }


  if (environment === 'test') {
    ENV.locationType = 'none';
    ENV.APP.autoboot = false;
  }


  if (environment === 'production') {
    // Production-specific configuration
    ENV.APP.analytics = process.env.ANALYTICS_ID;
  }


  return ENV;
};

12. Package Scripts

Ensure your package.json has the necessary scripts:

{
  "scripts": {
    "start": "ember serve",
    "build": "ember build --environment=production",
    "test": "ember test",
    "lint": "eslint .",
    "ember": "ember"
  }
}

Local Production Build Test

Before deploying, test the production build locally:

Terminal window
npm run build
ember serve --environment=production

Visit http://localhost:4200 to verify that your app renders correctly in production mode.

Deploying with Nixpacks

Nixpacks automatically detects your Node.js/Ember.js application and configures build and runtime environments without requiring a Dockerfile. This is the simplest deployment method for Ember.js applications.

Prerequisites for Nixpacks Deployment

  • Your Ember.js project pushed to a GitHub repository
  • Valid package.json with build and start scripts
  • No Dockerfile in the repository root (if one exists, Klutch.sh will use Docker instead)

Steps to Deploy with Nixpacks

  1. Push Your Ember.js Project to GitHub

    Initialize and push your project to GitHub if you haven’t already:

    Terminal window
    git init
    git add .
    git commit -m "Initial Ember.js app"
    git branch -M main
    git remote add origin git@github.com:YOUR_USERNAME/YOUR_REPO.git
    git push -u origin main
  2. Log In to Klutch.sh Dashboard

    Go to klutch.sh/app and sign in with your GitHub account.

  3. Create a Project

    Navigate to the Projects section and create a new project for your Ember.js app.

  4. Create an App

    Click “Create App” and select your GitHub repository.

  5. Select the Branch

    Choose the branch you want to deploy (typically main).

  6. Configure Traffic Type

    Select HTTP as the traffic type for Ember.js (a web framework serving HTML/assets).

  7. Set the Internal Port

    Set the internal port to 4200 – this is the port where the Ember development/production server listens.

  8. Add Environment Variables (Optional)

    Add any environment variables your Ember.js app requires:

    NODE_ENV=production
    API_URL=https://api.example.com
    SITE_NAME=My Ember App

    If you need to customize the Nixpacks build or start command, use these environment variables:

    • BUILD_COMMAND: Override the default build command (e.g., npm run build)
    • START_COMMAND: Override the default start command (e.g., ember serve --environment=production)
  9. Configure Compute Resources

    Select your region, compute size, and number of instances based on expected traffic.

  10. Deploy

    Click “Create” to start the deployment. Nixpacks will automatically build and deploy your Ember.js app. Your app will be available at a URL like https://example-app.klutch.sh.

Deploying with Docker

For more control over your deployment environment, you can use a Dockerfile. Klutch.sh automatically detects a Dockerfile in your repository root and uses it for deployment.

Creating a Dockerfile for Ember.js

Create a Dockerfile in the root of your Ember.js project:

# === Build stage ===
FROM node:18-alpine AS builder


WORKDIR /app


RUN npm install -g ember-cli


COPY package*.json ./
RUN npm install


COPY . .
RUN npm run build




# === Runtime stage ===
FROM node:18-alpine


WORKDIR /app


RUN npm install -g http-server


COPY --from=builder /app/dist ./dist


ENV PORT=4200
EXPOSE 4200


CMD ["http-server", "dist", "-p", "4200", "--gzip"]

Alternative Dockerfile for Nginx

For a lighter-weight deployment using Nginx:

# === Build stage ===
FROM node:18-alpine AS builder


WORKDIR /app


RUN npm install -g ember-cli


COPY package*.json ./
RUN npm install


COPY . .
RUN npm run build




# === Runtime stage (Nginx) ===
FROM nginx:alpine


COPY --from=builder /app/dist /usr/share/nginx/html


# Configure Nginx for SPA routing
RUN echo 'server { \
  listen 80; \
  location / { \
    root /usr/share/nginx/html; \
    try_files $uri $uri/ /index.html; \
  } \
}' > /etc/nginx/conf.d/default.conf


EXPOSE 80


CMD ["nginx", "-g", "daemon off;"]

Dockerfile Notes

  • Builder stage: Installs Ember CLI and builds your Ember app for production.
  • Runtime stage: Uses either http-server or Nginx to serve your built Ember application.
  • Port: The PORT environment variable is set to 4200 for http-server or 80 for Nginx.
  • Multi-stage build: Reduces final image size by excluding build tools and dev dependencies from the runtime container.

Steps to Deploy with Docker

  1. Create a Dockerfile

    Add the Dockerfile (shown above) to the root of your Ember.js repository.

  2. Test Locally (Optional)

    Build and test the Docker image locally:

    Terminal window
    docker build -t ember-app:latest .
    docker run -p 4200:4200 ember-app:latest

    Visit http://localhost:4200 to verify.

  3. Push to GitHub

    Commit and push the Dockerfile and your code:

    Terminal window
    git add Dockerfile
    git commit -m "Add Dockerfile for production deployment"
    git push origin main
  4. Create an App in Klutch.sh

    Go to klutch.sh/app, navigate to “Create App”, and select your repository.

  5. Configure the App
    • Traffic Type: Select HTTP
    • Internal Port: Set to 4200 (or 80 if using the Nginx Dockerfile)
    • Environment Variables: Add any required runtime variables
  6. Deploy

    Klutch.sh automatically detects the Dockerfile and uses it to build and deploy your app. Your app will be available at https://example-app.klutch.sh.

Environment Variables

Define all environment variables in the Klutch.sh dashboard. Here’s a recommended set for production:

NODE_ENV=production
API_URL=https://api.example.com
SITE_NAME=My Ember App
ANALYTICS_ID=your-analytics-id
AUTH_URL=https://auth.example.com

Accessing Environment Variables in Ember.js

Access environment variables in your config/environment.js:

ENV.APP.apiURL = process.env.API_URL || 'http://localhost:3000/api';
ENV.APP.siteName = process.env.SITE_NAME || 'My Ember App';

In components and services, inject the config:

import config from 'my-ember-app/config/environment';


export default class MyService extends Service {
  get apiURL() {
    return config.APP.apiURL;
  }
}

Persistent Storage

If your Ember.js application needs to store files or user-generated content, you can use persistent volumes in Klutch.sh.

Adding Persistent Volumes

  1. In the Klutch.sh dashboard, go to your app’s Volumes section.
  2. Click Add Volume.
  3. Set the mount path (e.g., /data, /uploads, or /var/www/uploads).
  4. Set the size (e.g., 1 GiB, 10 GiB).
  5. Save and redeploy your app.

Example: Handling File Uploads with a Backend API

app/services/upload.js
import Service from '@ember/service';


export default class UploadService extends Service {
  async uploadFile(file) {
    const formData = new FormData();
    formData.append('file', file);


    try {
      const response = await fetch('/api/upload', {
        method: 'POST',
        body: formData,
        headers: {
          'Authorization': `Bearer ${this.getToken()}`
        }
      });


      if (!response.ok) {
        throw new Error('Upload failed');
      }


      return await response.json();
    } catch (error) {
      console.error('Error uploading file:', error);
      throw error;
    }
  }


  getToken() {
    return localStorage.getItem('authToken') || '';
  }
}

Security Best Practices

1. HTTPS/SSL Enforcement

Klutch.sh automatically provides HTTPS for all deployed apps. Configure your Ember app to enforce HTTPS in production.

2. Content Security Policy

Set CSP headers in your backend or configure in Ember:

config/environment.js
if (environment === 'production') {
  ENV.APP.csp = {
    'default-src': ["'self'"],
    'script-src': ["'self'", "'unsafe-inline'"],
    'style-src': ["'self'", "'unsafe-inline'"],
    'img-src': ["'self'", 'data:', 'https:'],
    'connect-src': ["'self'", 'https://api.example.com']
  };
}

3. Authentication and Authorization

Implement secure authentication patterns:

app/services/auth.js
import Service from '@ember/service';
import { service } from '@ember/service';


export default class AuthService extends Service {
  @service router;


  async login(email, password) {
    try {
      const response = await fetch('/api/login', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({ email, password })
      });


      if (!response.ok) {
        throw new Error('Login failed');
      }


      const { token, user } = await response.json();
      localStorage.setItem('authToken', token);
      localStorage.setItem('user', JSON.stringify(user));


      return user;
    } catch (error) {
      console.error('Authentication error:', error);
      throw error;
    }
  }


  async logout() {
    localStorage.removeItem('authToken');
    localStorage.removeItem('user');
    this.router.transitionTo('login');
  }


  get isAuthenticated() {
    return !!localStorage.getItem('authToken');
  }
}

4. Input Validation

Validate all user inputs:

app/services/validator.js
import Service from '@ember/service';


export default class ValidatorService extends Service {
  validateEmail(email) {
    const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
    return emailRegex.test(email);
  }


  validatePassword(password) {
    return password.length >= 8;
  }


  validateArticle(article) {
    const errors = [];


    if (!article.title || article.title.trim().length === 0) {
      errors.push('Title is required');
    }


    if (!article.content || article.content.trim().length === 0) {
      errors.push('Content is required');
    }


    if (article.title && article.title.length > 200) {
      errors.push('Title must be less than 200 characters');
    }


    return { isValid: errors.length === 0, errors };
  }
}

5. Environment Variable Protection

Never commit sensitive data to version control:

API_KEY=your-secret-key
JWT_SECRET=your-jwt-secret
DATABASE_URL=postgresql://...

6. Dependency Security

Regularly audit and update dependencies:

Terminal window
npm audit
npm audit fix
npm update

7. XSS Prevention

Use Ember’s built-in XSS protection:

{{! Always use triple-curlies only for trusted HTML }}
{{escaped-value}}


{{! Use safe-string only for your own content }}
{{{trusted-html}}}

Monitoring and Logging

Health Check Endpoint

Implement a health check endpoint in your backend:

// Backend example (Node.js/Express)
app.get('/health', (req, res) => {
  res.json({
    status: 'healthy',
    timestamp: new Date().toISOString(),
    uptime: process.uptime()
  });
});

Client-Side Error Handling

Implement error handling in your Ember app:

app/services/error-handler.js
import Service from '@ember/service';
import { service } from '@ember/service';


export default class ErrorHandlerService extends Service {
  @service router;


  handleError(error) {
    console.error('Application error:', error);


    if (error.status === 401) {
      // Handle authentication error
      this.router.transitionTo('login');
    } else if (error.status === 403) {
      // Handle authorization error
      this.router.transitionTo('forbidden');
    } else if (error.status === 404) {
      // Handle not found
      this.router.transitionTo('not-found');
    } else {
      // Handle generic error
      this.router.transitionTo('error');
    }
  }
}

Structured Logging

Implement logging for production monitoring:

app/services/logger.js
import Service from '@ember/service';


export default class LoggerService extends Service {
  log(level, message, data = {}) {
    const entry = {
      timestamp: new Date().toISOString(),
      level,
      message,
      data
    };


    if (process.env.NODE_ENV === 'production') {
      // Send to logging service
      fetch('/api/logs', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify(entry)
      }).catch(err => console.error('Failed to log:', err));
    } else {
      console.log(JSON.stringify(entry));
    }
  }


  info(message, data) {
    this.log('info', message, data);
  }


  warn(message, data) {
    this.log('warn', message, data);
  }


  error(message, data) {
    this.log('error', message, data);

Custom Domains

To use a custom domain with your Klutch.sh-deployed Ember.js app:

1. Add the Domain in Klutch.sh

In the Klutch.sh dashboard, go to your app’s settings and add your custom domain (e.g., app.example.com).

2. Update Your DNS Provider

Update your DNS records with the CNAME provided by Klutch.sh:

CNAME: app.example.com → example-app.klutch.sh

3. Update Your App Configuration

Update your config/environment.js with the correct URL:

ENV.rootURL = '/';
ENV.APP.apiURL = process.env.API_URL || 'https://api.example.com';

4. Wait for DNS Propagation

DNS changes can take up to 48 hours to propagate. Use tools to verify:

Terminal window
nslookup app.example.com
# or
dig app.example.com

Once propagated, your Ember.js app will be accessible at your custom domain with automatic HTTPS.

Troubleshooting

Issue 1: Build Fails with “Out of Memory”

Error: JavaScript heap out of memory during build

Solutions:

  • Increase Node memory: NODE_OPTIONS=--max-old-space-size=4096 npm run build
  • Set BUILD_COMMAND in Klutch.sh: NODE_OPTIONS=--max-old-space-size=4096 npm run build
  • Review dependencies for unnecessary packages
  • Check Klutch.sh build logs for detailed error messages

Issue 2: App Shows Blank Page or 404 Errors

Error: App loads but shows no content or routes return 404

Solutions:

  • Verify config/environment.js has correct rootURL for your deployment path
  • Ensure all routes are properly defined in app/router.js
  • Check browser console for JavaScript errors
  • Verify your Ember version is compatible with your add-ons

Issue 3: API Requests Fail with CORS Error

Error: CORS policy: no 'Access-Control-Allow-Origin' header errors

Solutions:

  • Configure API_URL environment variable to point to your backend
  • Ensure backend CORS is configured to accept requests from your domain
  • Use a CORS proxy if backend doesn’t support CORS
  • Verify API endpoint URLs match your model/service configuration

Issue 4: Assets Not Loading (404 Errors)

Error: CSS, images, or JavaScript files return 404

Solutions:

  • Verify all asset paths are correct in app/styles/ and app/templates/
  • Ensure public/ directory contains all static assets
  • Check that asset imports use correct paths
  • Rebuild and verify dist/ directory is properly generated

Issue 5: Authentication Token Not Persisting

Error: Users get logged out on page refresh or navigation

Solutions:

  • Verify localStorage is being used to persist tokens
  • Check that authentication service initializes on app boot
  • Ensure beforeModel hooks restore authentication state
  • Verify token is sent with API requests

Best Practices

1. Use Computed Properties Effectively

import { computed } from '@ember/object';


export default class ArticleModel extends Model {
  @attr title;
  @attr content;
  @attr author;


  @computed('content')
  get contentLength() {
    return this.content?.length || 0;
  }


  @computed('contentLength')
  get readingTime() {
    return Math.ceil(this.contentLength / 200); // 200 words per minute
  }
}

2. Implement Loading States

app/controllers/articles.js
import Controller from '@ember/controller';
import { tracked } from '@glimmer/tracking';


export default class ArticlesController extends Controller {
  @tracked isLoading = false;


  async loadArticles() {
    this.isLoading = true;
    try {
      await this.store.findAll('article');
    } finally {
      this.isLoading = false;
    }
  }
}

3. Use Decorators for Cleaner Code

import { action } from '@ember/object';
import { service } from '@ember/service';


export default class MyComponent extends Component {
  @service api;
  @service router;
  @tracked articles = [];


  @action
  async saveArticle(article) {
    try {
      await this.api.createArticle(article);
      this.router.transitionTo('articles');
    } catch (error) {
      console.error('Error saving:', error);
    }
  }
}

4. Implement Proper Error Boundaries

Use try-catch in critical operations and handle errors gracefully.

5. Keep Components Small and Focused

Break down complex components into smaller, reusable components with single responsibilities.

6. Use Ember Data Correctly

Leverage Ember Data’s relationships and querying capabilities for cleaner code.

7. Implement Lazy Loading

Load large datasets incrementally rather than all at once.

8. Use Ember Concurrency for Async Operations

Manage concurrent async operations with proper cancellation and error handling.

9. Test Your Code

Write unit and integration tests for components, services, and routes.

10. Keep Dependencies Updated

Regularly update Ember.js and add-ons to get security patches and improvements.

Verifying Your Deployment

After deployment completes:

  1. Check the App URL: Visit your app at https://example-app.klutch.sh or your custom domain.
  2. Verify Routes Work: Navigate through different routes to ensure routing works.
  3. Test Components: Verify all components render and interactive features work.
  4. Check API Integration: Test that API calls work correctly.
  5. Check Performance: Use Google PageSpeed Insights to verify performance.
  6. Review Browser Console: Open F12 and verify no errors are present.
  7. Review Logs: Check the Klutch.sh dashboard logs for any runtime errors.

If your app doesn’t work as expected, review the troubleshooting section and check the logs in the Klutch.sh dashboard.
