Git Version Control and Web Hosting: Streamlining Development

Version control systems and web hosting services are essential tools for streamlining software development workflows. Using Git for version control enables developers to collaborate efficiently, track changes, revert to previous versions if needed, and maintain a complete history of the codebase. Meanwhile, web hosting provides a central server to deploy and run the latest code iteration for testing and delivery to end users. Combining Git version control with a web host streamlines development by connecting code collaboration, history tracking, and live deployment.

This article will provide an overview of how Git version control and web hosting work together to optimize development workflows. We’ll cover the benefits of using Git, examine options for web hosting and deployment, and go through best practices for integrating the two. With the right version control and hosting set up, teams can focus their energy on building great software instead of wrangling code.

Benefits of Git for Version Control

Git is the most widely used modern version control system, especially for web development teams. Version control systems allow developers to track changes to code over time and collaborate with teammates on a shared codebase. Here are some of the main benefits of using Git:

• Branching and merging – Developers can create separate branches of code that do not affect the main codebase. This enables them to work on experimental features or bug fixes isolated from the production version. Changes made on branches can later be merged back into the primary codebase.
• Distributed model – There is no centralized server for the code repository. Each developer keeps a complete local copy of the project’s history and can commit, branch, and merge independently. This allows for flexibility and protects against losing work if the central server goes down.
• Granular tracking of changes – Git stores snapshots of the full codebase each time a developer commits a change. This allows for tracing edits down to the line level and simplifies debugging code or reverting mistakes.
• Facilitates collaboration – Multiple developers can work on the same files and Git will handle merging their changes. Developers can use pull requests to propose and discuss changes before integrating into the official codebase.
• Open source – Git is free and open source, with robust community support for troubleshooting issues. There are many compatible web hosting options.

Overall, Git empowers developers to iterate quickly, experiment, collaborate seamlessly, and track changes accurately. For dynamic web projects with multiple contributors, Git is the ideal version control solution.

Choosing a Web Hosting Provider

To maximize the benefits of Git version control, code needs to be deployed to a web server for testing and delivery to end users. There are many web hosting provider options to consider when setting up Git deployments. Key criteria include:

• Git integration – The web host should provide built-in Git support or integration with third party Git tools for seamless code deployments from a repository.
• Developer optimized plans – Look for plans that include SSH access, one-click installs of frameworks like Node.js and Ruby on Rails, and integration with tools like MySQL, MongoDB, etc.
• Scalability – For large or growing projects, choose a provider that allows easy vertical and horizontal scaling of resources like bandwidth, storage, and compute power.
• Reliability and uptime – Look for hosts with redundant servers, frequent backups, and 24/7 monitoring for maximum reliability. Average uptime over the past year should exceed 99.9%.
• Security – The provider should use industry standard security protocols like SFTP and offer SSL certificates for sites. Some offer extra security options like IP whitelisting and two-factor authentication.
• Support options – Good documentation, knowledge bases, chat support, and phone support ensure you can get timely answers if issues occur.
• Affordable pricing – Balance desired features and scale needs with reasonable costs, looking for unlimited repositories, bandwidth, and storage at lower tiers.

Top providers like Github Pages, Heroku, Amazon Web Services, and DigitalOcean meet many of these criteria at various pricing levels suitable for personal or enterprise use.

Basic Git/Web Host Workflow

With Git installed locally and a web host account set up, connecting the two typically follows this general workflow:

1. Developers create a Git repository locally and push committed code changes to a master remote repository hosted at GitHub, Bitbucket, GitLab, or a similar service.
2. For deployment, the web server pulls code from this master repository when changes are pushed. Often a separate branch like ‘production’ is used for the live site.
3. A continuous integration (CI) tool like Jenkins can automate this deployment by triggering a pull from the production branch of the repo whenever a change is detected.
4. Developers create branches off the main repo to work on changes or features. When ready, they open pull requests to propose merging their branch back into the master.
5. After peer review and testing, the pull request is approved and merged into the master repo, triggering deployment to the live site.
6. Issues can be tracked and associated with specific branches or pull requests in the repo. The pull request approval process ensures only stable, reviewed code ends up on production.

This basic workflow enables smooth collaboration between developers and consistent delivery of stable code iterations to end users. More advanced workflows are also possible.

Deploying a Git Repo to a Web Host

The specific steps to connect a Git repository to a web host vary slightly depending on the host and tools used. However, the general procedure is:

1. Create a remote repository on GitHub, Bitbucket, or a similar service to hold the master branch and track commits from developers.
2. Set up local Git repositories on each developer’s machine and connect them to the common remote. Commit changes locally and push to the remote repo frequently.
3. On the web host, install Git if it is not already available. For hosts without native Git integration, install a wrapper like Git Deploy.
4. Add the web host as a remote destination and push the master branch from the Git repository to the host. Some hosts provide a Git URL for this purpose.
5. Configure a post-receive hook in the repository to trigger automatic deployment to the web host when changes are pushed.
6. Set up any necessary web server configuration and libraries on the host to run the codebase. Test that the initial deployment works.
7. As development continues, pushing to the master remote will now automatically deploy the latest committed code to the live site.

With this setup in place, the development and operations sides of the team can work together smoothly. Developers use Git for version control among themselves, while server changes are minimized to deploys triggered by new code pushes.

Automating Deploys with CI Tools

Having to manually push code from the Git repository to the web host each time can become burdensome. Continuous integration (CI) tools help automate this process by monitoring repositories and triggering actions like code deployments when changes occur.

Popular CI tools like Jenkins, CircleCI, Travis CI, and Codeship integrate seamlessly with Git repositories for automatic deployments. The general workflow is:

1. Configure the CI tool to watch the branches of your Git repository. Set up notifications, triggers, and access tokens as needed.
2. Define a deploy job that pulls code from a production branch and pushes it live using a script or integration with the web host’s API.
3. Set triggers so deploy jobs run when pull requests are merged or changes pushed to certain branches. You can require passing tests first.
4. The CI service now monitors the repo and responds to events by running pre-configured jobs like deployments.
5. Developers just push changes to the repo as usual while the CI tool handles standard deploy tasks without any extra effort.

CI services can also run test suites before deploying and even roll back changes if tests fail. For more complex environments with multiple servers, CI tools help ensure consistency and reduce chances for error when deploying application updates.

Using Git Hooks and Custom Scripts

In some cases, the default CI options may not provide enough flexibility. Git hooks allow running custom scripts locally or on the server when events like new commits occur. Common uses of hooks include:

• Running tests before a commit to ensure code quality
• Enforcing coding standards using a linter before push
• Blocking pushes that would leave the master branch in a broken state
• Backing up data before new code updates
• Notifying other services after deploy

Server-side hooks like post-receive run on the host when it detects a push. Combined with a custom shell script, this can deploy to non-standard locations or perform additional actions like clearing caches. Pre-receive hooks on the repository run locally before changes are accepted, allowing for tests and validations.

For complex deployments, Git hooks provide a programmable way to enhance integrations between version control and web hosting services. Teams can standardize workflows while still retaining control over custom actions their setup requires.

Deployment Best Practices

Following some simple best practices helps streamline the integration of Git version control with a web host deployment workflow:

• Use separate branches for development, staging, and production deployments to avoid mixing untested code with the live site.
• Tag releases corresponding to live site updates for easy reference in commit history.
• Only allow fast-forward merges to master branch to prevent rewriting public history.
• Test integrations thoroughly before relying on CI tools for mission-critical deployments.
• Use Git hooks to standardize workflows and prevent common mistakes.
• Monitor deployments and rollback if necessary to limit downtime from issues.
• Secure remote access using SSH keys instead of passwords.
• Rate limit deployment events to avoid overwhelming servers with rapid changes.
• Automate everything possible so developers can focus on writing code rather than deployment details.

Following DevOps principles for integrating version control, testing, and hosting streamlines code collaboration and reliable, rapid releases. Adopting Git and continuous delivery best practices paves the way for more innovation.
