Async Support

Basically, you can use async and await in your templates as long as you configure Eta to be in async mode. Remember: if you're in async mode and are working with partials, you need to await include(...)!

Example

function asyncFunc() {

return new Promise((resolve) => {

setTimeout(() => {

resolve("HI FROM ASYNC")

}, 20)

})

}

let result = await Eta.render(

"<%= it.name %>: <%= await it.asyncFunc() %>",

{ name: "Ada Lovelace", asyncFunc: asyncFunc },

{ async: true }

)

// 'Ada Lovelace: HI FROM ASYNC'

Special Functions

There are also two functions, renderAsync and renderFileAsync which are the equivalents of their respective functions with builtin async support.

Example

function asyncFunc() {

return new Promise((resolve) => {

setTimeout(() => {

resolve("HI FROM ASYNC")

}, 20)

})

}

let result = await Eta.renderAsync(

"<%= it.name %>: <%= await it.asyncFunc() %>",

{ name: "Ada Lovelace", asyncFunc }

)
