## What it is
EJS is an embedded JavaScript templating engine for Node.js and browsers that lets you generate HTML with plain JavaScript in `<% %>` tags. It integrates with Express as a view engine and supports includes, caching, custom delimiters, and client-side rendering.

## Use cases
- render html pages from node.js server
- use a view engine with express
- generate html emails from templates
- compile templates for client-side rendering
- build server-rendered web pages with javascript templates

## When to choose
- you want simple, plain-JavaScript templating without a custom DSL
- you use Express and need a compatible view engine
- you need templates that run in both Node and the browser

## When to avoid
- you want automatic XSS protection with strict escaping by default
- you prefer logic-less templates like Handlebars
- you need component-based frontend rendering like React or Vue

## Facets
- artifact type: library
- maturity: stable
- function: templating
- domain: web-development, frontend, backend
- platform: browser, bun, cross-platform
- tags: template-engine, express-view-engine, html-templates, server-side-rendering, nodejs, deno
