Eta is a lightweight, fast embedded JavaScript templating engine written in TypeScript that runs in Node, Deno, and the browser. It supports layouts, partials, plugins, custom delimiters, caching, and precompilation, positioning itself as a more configurable EJS alternative with only ~3.5 KB minzipped and zero dependencies.

Use cases

• render html templates in node.js
• ejs alternative for javascript templating
• template engine that works in deno and the browser
• express or fastify view engine for server-side html
• html templates with layouts and partials
• small lightweight templating library for bundling in the frontend

When to choose

• You want an EJS-like syntax but need Deno support, layouts, or custom delimiters out of the box
• Bundle size and render speed matter - it is ~3.5 KB minzipped with zero dependencies
• You need TypeScript types, ESM exports, informative syntax errors, and plugin/custom-tag extensibility

When to avoid

• You need component-based or JSX-style templates rather than embedded-tag templates
• You rely on CommonJS require - Eta v4 is ESM-only
• You need a large ecosystem of prebuilt helpers (e.g. Handlebars) or logic-less templating like Mustache
