Loops

You can loop over objects and arrays using the @each tag. It works similar to the for of loop in JavaScript.

view.render('users', {
  users: [
    {
      username: 'virk',
    },
    {
      username: 'romain',
    },
    {
      username: 'nikk',
    },
  ]
})

@each(user in users)
  <li> {{ user.username }} </li>
@end

You can access the loop index as shown in the following example

@each((user, index) in users)
  <li> {{ index + 1 }} {{ user.username }} </li>
@end

Similarly you can also loop over an object and access its key and value.

view.render('recipes', {
  food: {
    ketchup: '5 tbsp',
    mustard: '1 tbsp',
    pickle: '0 tbsp'
  }
})

@each((amount, ingredient) in food)
  <li> Use {{ amount }} of {{ ingredient }} </li>
@end

The @each tag works just fine with async code inside it. Here's an example of the same.

view.render('users', {
  users: [
    {
      username: 'virk',
      posts: async () => [{ title: 'Adonis 101' }],
    },
    {
      username: 'romain',
      posts: async () => [{ title: 'Flydrive 101' }],
    }
  ]
})

@each(user in users)
  <h2> {{ user.username }} posts </h2>

  @each(post in await user.posts())
    <p> {{ post.title }} </p>
  @end
@end
