How to automate deployment of Express.js apps on Cloudways using CI/CD tools?
To automate the deployment of Express.js apps on Cloudways using CI/CD tools, you can follow the steps below:
- Set up a Git repository: Create a Git repository to store your Express.js app code. You can use popular Git hosting platforms like GitHub, GitLab, or Bitbucket.
- Configure CI/CD tool: Choose a CI/CD tool like Jenkins, Travis CI, or CircleCI. Set up the tool to connect to your Git repository and trigger the CI/CD pipeline whenever changes are pushed to the repository.
- Write CI/CD pipeline script: Create a pipeline script that defines the steps required to build and deploy your Express.js app on Cloudways. The script typically includes steps such as installing dependencies, running tests, building the app, and deploying it to Cloudways.
- Configure deployment settings: In the pipeline script, specify the Cloudways server details, such as the server IP, username, and password. You can store these details securely as encrypted environment variables or in a secure credentials store provided by the CI/CD tool.
- Install Cloudways CLI: Install the Cloudways CLI on your CI/CD server to interact with your Cloudways account. The CLI allows you to deploy, manage, and scale your applications on Cloudways programmatically.
- Build and deploy the app: In the CI/CD pipeline script, run the necessary commands to install dependencies (npm install), run tests (npm test), build the app (npm build), and finally, deploy the app to Cloudways (cloudwayscli application deploy).
- Monitor the deployment process: Set up logging and notifications in your CI/CD tool to monitor the deployment process. This ensures that any issues or errors are promptly addressed.
- Test and verify the deployment: After the deployment, you can run additional post-deployment tests to ensure that the app is running correctly on Cloudways.
By automating the deployment process using CI/CD tools, you can streamline the deployment process, reduce human error, and enable continuous integration and deployment for your Express.js apps on Cloudways.
How to connect a domain to a Cloudways server for Express.js deployment?
To connect a domain to a Cloudways server for Express.js deployment, follow these steps:
- Log in to your Cloudways account and go to the Servers tab.
- Create a server if you haven't done so already. Choose the desired provider, server size, and location.
- Once your server is ready, click on your server name to access the server management page.
- In the left sidebar, go to the Applications section and click on the Add Application button.
- Select the application type as "Node.js" and choose the desired version.
- Fill in the application details like the application name, domain, and application folder. Click on the Add Application button to create it.
- Once the application is created, go to the Access Details tab. Note down the IP address and SSH port.
- Now, go to your domain registrar's website where you purchased the domain.
- Find the DNS management or domain management section in your domain registrar's control panel.
- Create an "A" record (Address record) or modify the existing one for your domain. Set the value of the "A" record to the IP address noted in step 7.
- Save the changes and wait for the DNS propagation to complete. It may take up to 24-48 hours.
- Once the DNS propagates, go back to the Cloudways server management page.
- In the left sidebar, go to the Applications section and click on your Express.js application.
- In the Application Management section, click on the Domain Management button.

- You can also set up redirects, caching, and other settings if desired.
- Save the changes and your domain will be connected to your Cloudways server for Express.js deployment.
- To verify if the setup is correct, open a web browser and type "http://yourdomain.com". You should see your Express.js application running.
Note: SSL certificates may take some time to install and propagate. Make sure to check if your domain is accessible using both "http" and "https" after a few hours.
What is the maximum number of concurrent connections Express.js can handle on Cloudways?
Express.js, being a moderately lightweight framework, does not have a defined maximum number of concurrent connections it can handle out of the box. Instead, the maximum number of concurrent connections that Express.js, or any Node.js framework, can handle depends on the underlying hardware and infrastructure on which it is deployed.
When using Express.js on Cloudways, the maximum number of concurrent connections that can be handled will depend on the Cloudways server specifications and the performance capabilities of the server stack (typically Nginx or Apache) being used. Cloudways provides several server options with varying specifications, allowing users to scale their server resources according to their needs.
To determine the maximum number of concurrent connections your Express.js application can handle on Cloudways, it is recommended to monitor the server's resource usage, including CPU, memory, and network traffic, as well as the response times of your application under various loads. This can be done using monitoring tools or through the Cloudways platform itself.
What is Express.js and why should I use it?
Express.js is a fast and minimalist web application framework for Node.js. It provides a set of flexible and robust features for building web applications and APIs. Here are a few reasons why you should consider using Express.js:
