The chapter's exercises

  1. The menu on a scroll

    Exercise 1 · 200 XP · 5 objectives checked by tests

    The Adventurers' Guild has just equipped its members with magic scrolls: they can browse the taverns of the region on them, book a table… Gorm wants the Drunken Dragon to be listed. The trouble is, scrolls can't read HTML: they speak JSON.

    JSON API$this->json()Serializer#[Groups]

  2. A dish on demand

    Exercise 2 · 220 XP · 5 objectives checked by tests

    The adventurers love having the menu on their scroll. Now they want to know what others think of a dish before ordering it (Gimli swears by it).

  3. Booking by pigeon

    Exercise 3 · 240 XP · 5 objectives checked by tests

    Big news: scrolls can now send messages. No need to cross the forest to book a table any more: a magic pigeon takes care of it. It brings a JSON like this one:

    POST JSONDTO#[MapRequestPayload]201 / 400 / 422

  4. The guild's seal

    Exercise 4 · 250 XP · 5 objectives checked by tests

    Disaster: some smart aleck has booked every table at the Drunken Dragon for the next ten years, under the name “Sauron”. Anyone can send a pigeon, and that's exactly the problem.

  5. Filtering the menu

    Exercise 5 · 240 XP · 5 objectives checked by tests

    The Circle of Mages is on a diet: “Nothing above 4 gold pieces, and only drinks, thank you.” Rather than downloading the whole menu and sorting it themselves, the scrolls want to filter:

    #[MapQueryString]EnumQueryBuildervalidationFailedStatusCode

  6. 🐉 Boss: the lost pigeon

    Exercise 6 · 280 XP · 4 objectives checked by tests

    Pippin is back from a crash course, “Scrolls in three days”. He has “simplified” a thing or two in the API.
