Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited advanced features compared to other templating engines

   EJS lacks sophisticated template inheritance and complex control structures found in more feature-rich engines like Handlebars or Mustache.

2. 02

   Security vulnerabilities if not properly sanitized

   Direct embedding of JavaScript can lead to XSS attacks if user input is not correctly escaped or sanitized before rendering.

3. 03

   Performance limitations for large-scale applications

   EJS's reliance on plain JavaScript for templating can become a bottleneck in high-traffic scenarios where performance optimizations are critical.

What it does well

• Embeds JavaScript directly in HTML

• Simple syntax for easy integration with web projects

• Supports server-side rendering of dynamic content
