Syntax
Async Templates
Eta supports optional async support using the async and await keywords (to support ES5 and lower, use a plugin or transpiler).
Basic Syntax
Essentially, you can use await just like in regular JavaScript.
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'
