Error: could not resolve entry module “index.html”
An “entry module” in a web application refers to the main JavaScript file that serves as the entry point for your application. The error message “could not resolve entry module ‘index.html'” indicates that the specified entry module file could not be found or resolved. Here are a few possible reasons and solutions to fix this issue:
- Make sure the file name and path are correct: Verify that the “index.html” file exists in the specified location. Double-check for any typos in the filename or incorrect path.
- Check the configuration file: If you are using a bundler like Webpack or Parcel, make sure the configuration file (e.g., webpack.config.js or parcel.config.js) is properly set up. Check the entry point configuration and ensure it points to the correct file.
- Ensure proper file structure: In many web applications, the entry module is usually a JavaScript file (e.g., app.js) rather than an HTML file. Your HTML file (e.g., index.html) should include a reference to the JavaScript file using the script tag. Verify that the correct HTML file is being referenced as the entry module and the JavaScript file is included.
- Check for any build errors: If you are using a build tool, ensure that there are no errors in the build process. Inspect the build logs to find any potential errors or warnings that could be causing the issue.
Example:
My App
Hello, world!
console.log("Entry module script");
