@enzoclock thank you! I appreciate this suggestion, but I think it's best to keep the Eta API as minimal as possible.

However, I do like your solution. Maybe you could submit a PR to add that to the Eta documentation here?

var w = express()
var eta = new Eta({ views: path.join(__dirname, "views"), cache: false })
w.engine("eta", buildEtaEngine())
w.set("view engine", "eta")
w.set("views",eta.config.views) // idk why need add this, even though the config is already there above
function buildEtaEngine(): (
	path: string,
	opts: any,
	callback: (error: Error | null, renderedTemplate?: string) => void
) => void {
	return (path: string, opts: any, callback: (error: Error | null, renderedTemplate?: string) => void) => {
		try {
			const fileContent = eta.readFile(path)
			const renderedTemplate = eta.renderString(fileContent, opts)
			callback(null, renderedTemplate)
		} catch (error) {
			callback(error as Error)
		}
	}
