FAQs
"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).
Integrations
@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 });
},
},
}
