Declaring aliases​

Define an alias that merges some information from links as computed properties, this is a way of flattening a nested structure:

  1. alias ReviewAlias := Review {
  2. # It will already have all the Review
  3. # properties and links.
  4. author_name := .author.name,
  5. movie_title := .movie.title,
  6. }

Define an alias for traversing a backlink, this is especially useful for GraphQL access:

  1. alias MovieAlias := Movie {
  2. # A computed link for accessing all the
  3. # reviews for this movie.
  4. reviews := .<movie[is Review]
  5. }

Aliases allow to use the full power of EdgeQL (expressions, aggregate functions, backlink navigation) from GraphQL.

The aliases defined above allow you to query MovieAlias with GraphQL.
