How to manage code refactoring and optimization of projects in GitLab

With the continuous evolution of software development, code refactoring and optimization have become important to ensure project quality and performance one of the important links. On a code hosting platform like GitLab, we can manage the code refactoring and optimization of the project efficiently and orderly. This article will introduce how to use the functions and features of GitLab to refactor and optimize code to achieve better project quality and performance.

1. Create a new branch

Before refactoring and optimizing the code, we first need to create a new branch on GitLab. The new branch allows us to modify and adjust the code without affecting the main branch. We can give the branch a meaningful name based on specific refactoring and optimization goals to facilitate subsequent management and tracking.

The steps to create a new branch on GitLab are as follows:

• Open the main page of the project
• Click the branch drop-down menu and select "New branch"
• Enter the branch name in the pop-up dialog box, select the branch based on, and click the "Create branch" button

2. Submit the code

After creating After the new branch, we can submit the code that needs to be refactored and optimized to this branch. In GitLab, we can use the following command line to submit code:

git add .
git commit -m "代码重构和优化的详细描述"
git push origin 新分支名字

Or we can also use the web interface provided by GitLab to submit code:

• Open the main page of the project
• Click the " " button, select "New file" or "Upload file"
• Enter the file name and code content, and click the "Commit changes" button

3. Carry out code refactoring and optimization

After submitting the code to be refactored and optimized on the new branch, we can start the actual refactoring and optimization work. The following are some common code refactoring and optimization methods:

3.1 Extracting functions

When the function of a function is too complex or the code is too lengthy, we can extract part of the code. Create new functions to improve code readability and maintainability. The following is an example:

// 原函数
function complexFunction() {
  // 复杂的代码逻辑
}

// 重构后的代码
function extractFunction1() {
  // 提取出来的代码逻辑
}

function complexFunction() {
  // 复杂的代码逻辑
  extractFunction1();
}

3.2 Optimizing loops

Where loops are used in the code, we can consider optimizing the performance of the loop. For example, use more efficient iterators instead of simple for loops, or use parallelization to execute loops to make full use of CPU resources. The following is an example:

// 原始的循环
for (let i = 0; i < arr.length; i++) {
  // 循环体
}

// 优化后的循环
arr.forEach((elem) => {
  // 循环体
});

3.3 Delete duplicate code

Duplicate code is a manifestation of low code quality. We can improve the maintainability and scalability of the code by deleting duplicate code. sex. Functions and classes can be used to encapsulate and organize repeated code. The following is an example:

// 重复的代码
function func1() {
  // 代码逻辑1
}

function func2() {
  // 代码逻辑1
}

// 优化后的代码
function commonFunc() {
  // 代码逻辑1
}

function func1() {
  commonFunc();
}

function func2() {
  commonFunc();
}

4. Submit the refactored and optimized code

After a series of code refactoring and optimization, we can make these changes Commit to a new branch on GitLab. Again use the command line or the GitLab web interface to complete the commit operation.

5. Initiate a Pull Request

Once we have completed the refactoring and optimization of the code and committed these changes to a new branch on GitLab, we can initiate a Pull Request (PR) to merge the changes from the new branch into the main branch. During the PR process, other team members can review and discuss our code to ensure code quality and rationality.

The steps to initiate a PR on GitLab are as follows:

• Open the main page of the project
• Click the "Merge request" button
• Select the source branch and target branch, fill in the details of the PR and click the "Submit merge request" button

6. Merge code

Finally, after review and review by team members After the discussion, we can merge the changes from the new branch into the main branch of the project. You can use the following command line to merge the code:

git checkout 主分支名字
git merge 新分支名字
git push origin 主分支名字

Or we can also complete the merge operation on GitLab:

• Open the PR page
• Click "Merge" Button
• After confirming the merge, click the "Merge" button

Summary:

Managing the code refactoring and optimization of the project in GitLab can greatly improve the team's Development efficiency and code quality. By taking advantage of the functions and features provided by GitLab, we can modify and optimize the code without affecting the main branch, collaborate and discuss with team members, and ensure the maintainability and scalability of the code. I hope that the methods and examples introduced in this article can be helpful to everyone when refactoring and optimizing code in GitLab.
