You're viewing the source for Eta v3, which we just released! For v2, visit the old branch.
Eta is a lightweight and blazing fast embedded JS templating engine that works inside Node, Deno, and the browser. It's written in TypeScript and emphasizes great performance, configurability, and small bundle size.

Install Eta
npm install eta
In the root of your project, create templates/simple.eta
Hi <%= it.name %>!
Then, in your JS file:
import { Eta } from "eta";
// import { Eta } from "https://deno.land/x/[email protected]/src/index.ts";
const eta = new Eta({ views: path.join(__dirname, "templates") });
// Render a template
const res = eta.render("./simple", { name: "Ben" });
console.log(res); // Hi Ben!
"Eta" means tiny in Esperanto. Plus, it can be used as an acronym for all sorts of cool phrases: "ECMAScript Template Awesomeness", "Embedded Templating Alternative", etc....
Additionally, Eta is a letter of the Greek alphabet (it stands for all sorts of cool things in various mathematical fields, including efficiency) and is three letters long (perfect for a file extension).
@shadowtime2000 created eta-vscode.
eslint-plugin-eta was created to provide an ESLint processor so you can lint your Eta templates.
Currently there is no official Webpack integration but @clshortfuse shared the loader he uses:
{
loader: 'html-loader',
options: {
preprocessor(content, loaderContext) {
return eta.render(content, {}, { filename: loaderContext.resourcePath });
},
},
}
