Encountering an issue where your React changes are not being updated in the output/public folder when using Symfony Encore and Webpack? Don’t worry, you’re not alone. In this article, we will walk through the steps to troubleshoot and fix this problem, ensuring that your compiled changes are reflected in the output folder. Let’s dive in!
Understanding the Issue Subheading: How Symfony Encore/Webpack Works
- Briefly explain the purpose of Symfony Encore and Webpack in the context of your project.
- Mention that when you make changes to your React file (App.jsx) and save it, Webpack compiles the changes and updates the output folder.
- Emphasize that initially, the changes are reflected correctly in the browser.
The Problem Subheading: React Changes Not Updating in Output Folder
- Describe the issue: After the initial successful compilation, subsequent changes to App.jsx are compiled by Webpack without any console errors, but the output folder is not being updated.
- Explain the impact: As a result, the browser does not show any new changes because the compiled files in the output folder remain unchanged.
Troubleshooting and Fixing the Issue Subheading: Step 1 – Project Configuration
- Explain that we’ll start by reviewing the project configuration files to ensure everything is set up correctly.
- Mention the files involved: docker-compose.yml, webpack.config.js, /assets/bootstrap.js, and app.jsx.
- Share code snippets of the relevant parts of these files to provide context.
Subheading: Step 2 – Verify Docker Setup
- Explain that since you’re using Docker with a Nginx web server on a macOS system, it’s essential to ensure the Docker setup is correct.
- Encourage users to review their docker-compose.yml file and verify that the volumes and links are properly configured.
Subheading: Step 3 – Checking Webpack Configuration
- Discuss the webpack.config.js file and its role in managing the compilation process.
- Highlight key configurations such as the output path, public path, entry point, and React preset.
- Suggest verifying that the configuration matches the project requirements and doesn’t contain any errors or omissions.
Subheading: Step 4 – Reviewing Bootstrap.js and App.jsx
- Explain the purpose of bootstrap.js and how it ties everything together.
- Discuss the contents of the file, including the import statements and ReactDOM.createRoot.
- Examine app.jsx and emphasize the importance of correctly saving and exporting changes.
- Mention that this is the file where the actual React component (App) is defined.
Subheading: Step 5 – Twig File Integration
- Describe the role of the Twig file in rendering the React components on the frontend.
- Briefly explain the relevant parts of the Twig file, such as title, stylesheets, and JavaScript tags.
- Highlight the necessity of ensuring the correct inclusion of the compiled JavaScript in the rendered HTML.
Resolving the Issue Subheading: Final Steps to Update the Output Folder
- Summarize the troubleshooting steps performed so far.
- Emphasize the importance of following each step carefully to resolve the issue.
Subheading: Clearing Cache and Rebuilding
- Recommend clearing any existing cache related to the compilation process.
- Provide instructions on how to clear cache (if applicable) and rebuild the project.
Subheading: Testing the Output Folder
- After clearing the cache and rebuilding, advise users to test if the compiled changes are now updating in the output folder.
- Instruct users to make additional changes to App.jsx, save the file, and verify if the output folder updates accordingly.
