How to Handle Conflicts in Version Control When Working on Web Projects

Conflict is a part of life, and it is no different in a professional setup, especially when it comes to software development. As developers, we work on complex projects with multiple team members, and keeping track of changes to the codebase can be challenging. The use of version control systems comes in handy in such scenarios. Version control systems help in tracking changes to the codebase history, allowing developers to work together without stepping on each other's toes. However, conflicts can arise when multiple team members work on the same codebase simultaneously. In this guide, we explore how to handle conflicts in version control when working on web projects.

What are Version Control and Conflict Management?

Version control is a type of software that helps manage changes in the codebase. It maintains a timeline of changes in the codebase and records who made the changes, when it was made, and the reason for the change.

Conflict management is the process of identifying conflicts in the codebase and resolving them. Conflicts typically occur when team members work on the same codebase simultaneously and make different changes to the same file. Conflicts must be resolved to avoid conflicts later on in the development process, which can lead to deployment delays and project failures.

Understanding Different Version Control Systems

Before we delve deeper into conflict resolution, it is essential to understand the different version control systems available. While there are various version control systems, the most commonly used ones are Git, SVN, and Mercurial.

Git is the most popular version control system, favored for its speed and efficiency. It is an open-source version control system, and its popularity can be attributed to platforms like GitHub, which provide a free hosting service for public Git repositories. Git works on a distributed model, which means developers have complete replicas of the codebase, and it is easy to merge changes from various team members.

SVN, on the other hand, is a centralized version control system that uses a single repository for storing all the changes. The SVN repository holds the main codebase, and developers can update their local repository to mirror the central repository. While SVN has been around for a while, it is slowly being replaced by Git.

Mercurial is another distributed version control system similar to Git. Mercurial offers similar features to Git but is less popular.

Conflict Resolution with Git

Given its popularity, we'll focus on resolving conflicts with Git. Conflict resolution in Git involves the following steps:

1. Identify the Cause of the Conflict: Git identifies potential conflicts automatically when conflicting changes are committed to the same file. A developer is notified of the conflict when they try to merge or push a change to the central repository.

2. Retrieve the Latest Codebase: When a conflict is detected, the first step to resolving it is to retrieve the latest codebase to identify the cause of the conflict. Developers can use the 'git pull' command to retrieve the latest codebase from the central repository and compare it with their local repository.

3. Resolve the Conflict: Git provides developers with different tools to resolve conflicts, such as the 'git mergetool' command, which opens a merge-tool to help resolve the conflict.

4. Commit and Push the Change: After resolving the conflict, the changes need to be committed to the local repository and pushed back to the central repository.

Conflict Resolution with SVN

SVN has its conflict resolution mechanism. When a conflict is detected, the SVN client shows the developer the files with conflicts, and options to resolve the conflict are provided.

The developer can choose to accept the local changes or repository changes, or they can choose to manually merge the conflicting changes. After resolving the conflict, the changes can be committed back to the repository.

Tips to Prevent Conflicts

While conflicts cannot be entirely avoided, taking a proactive approach can help prevent them:

1. Code Ignoring: When working on a large project, it is advisable to break down the codebase into smaller files and work on separate sections, limiting the likelihood of conflicts when multiple developers work on the same file.

2. Communication: Communication is key to resolving conflicts before they escalate. Team members should communicate about their changes to avoid stepping on each other's toes.

3. Frequent Uploading: Developers should commit their changes frequently to avoid large, complex changes, making it harder to identify conflicts.

4. Code Reviews: Code reviews are a great way to identify conflicts. Regular code reviews before committing changes to the central repository can help catch conflicts early on.


Handling conflicts in version control systems is crucial when working on web projects. Conflict resolution is often a complex process involving identifying the cause of the conflict, retrieving the latest codebase, resolving the conflict, and committing and pushing the change. Different version control systems have different conflict resolution mechanisms, with Git and SVN being the most commonly used ones. To prevent conflicts, developers can choose to break down large codebases into smaller files, frequently upload changes, communicate, and regularly review code. In addition, being mindful of code best practices can avoid conflicts in the long run.
