WHY EJS IS NOT WORKING

EJS is a common JavaScript templating engine used to render HTML pages dynamically. But sometimes, things don't go as planned and EJS may not work as expected. If you find yourself in this situation, you're not alone. Non-functioning EJS can be a real pain, but understanding the potential causes and having a troubleshooting plan can help you resolve the issue and get your code running smoothly again.

1. Incorrect EJS Syntax

EJS relies on proper syntax to function correctly. Common errors include missing curly braces, incorrect nesting, and typos. Ensure you’re using the correct syntax and that all opening curly braces ({) have a corresponding closing curly brace (}). Double-check your code for any typos or misspellings.

2. Improper Data Passing

Your EJS template expects specific data to be passed to it from the server. If the data isn’t passed correctly or is in the wrong format, the template won’t render properly. Verify that you’re passing the correct data object, and make sure the data is in the appropriate format, such as JSON or an object literal.

3. Missing EJS Dependency

EJS requires a dependency to be installed in your project. If you’re using npm, run “npm install ejs” to install the necessary dependency. For other package managers, refer to their documentation for installation instructions.

4. Incorrect Template File Extension

EJS templates typically use the “.ejs” file extension. If you’re using a different extension, the template engine may not recognize the file and will fail to render it. Ensure that your template file has the correct extension.

5. Template Engine Not Rendering

Sometimes, the template engine itself may not be rendering the template. This can happen if the template engine is not configured correctly or if there’s an issue with the rendering process. Check your configuration and make sure the template engine is set up properly.

Conclusion

EJS is a powerful tool for generating dynamic HTML content, but it can be frustrating when things don’t work as expected. By understanding the common causes of EJS issues and following a troubleshooting plan, you can quickly identify and resolve the problem, getting your code back up and running in no time.
