Примеры
Все примеры работают на одной демо-инфраструктуре: облака, VPS, роутеры, гипервизоры, рабочие станции и ферма контейнеров. Поэтому поведение можно сравнивать между примерами. Исходник под каждым примером — это тот же файл, который его рисует.
Базовый граф
Сущности, связи, иконки и радиальная раскладка. Клик по узлу открывает подробности, перетаскивание двигает узел.

Переключение представлений
Один набор данных, две топологии. Счётчик считает страница через vue-asset-map/core, поэтому он всегда согласован с тем, что рисует карта.

Свёрнутая группа из 14 узлов
Четырнадцать контейнеров на одном гипервизоре складываются в один групповой узел со счётчиком. Их рёбра переезжают на группу, а те, что были внутренними, считаются, а не рисуются. Клик раскрывает.

Трассировка пути между двумя узлами
autoPath строит путь сам: два узла выбраны заранее, поэтому путь ниже уже подсвечен, и ничего вызывать не пришлось. Чтобы проследить свою пару, зажмите Shift и кликните по двум узлам. Shift работает как аддитивный модификатор на любой платформе, в отличие от Ctrl+клика, который macOS трактует как правый клик, а клик с модификатором только выделяет и окном путь не закрывает. Маршрут приходит событием path-change; ищется он по исходному графу, а подсвечивается по свёрнутому.

Всё заменяемое — заменено
Остальные примеры меняют что-то одно. Этот оставляет граф, проекции, раскладку, поиск и обходы — и заменяет каждый пиксель над ними.
Ничего из этого не лезет во внутренности пакета: каждая часть — документированный проп или слот.
- Фигуры вместо кругов. Компонент из
nodeTypesрисует пилюлю, ромб, квадрат, шестиугольник, скруглённый квадрат и восьмиугольник — по одной на вид. Фигура должна была заменить круг целиком, поэтому это компонент, а не слот#node-{type}: слот подменяет то, что внутри круга, и оставляет сам круг. Тип несёт фигура, поэтому карта читается и без цвета. - Прямоугольная разводка. Компонент из
edgeTypesменяет кривую Безье на ступенчатую линию и ставит на неё свою плашку. Цвет и штрих по-прежнему приходят изlinkTypesчерезuseMapContext(). - Свой интерфейс.
showToolbarвыключен; панель над картой — обычная разметка страницы, управляющаяv-model:filters,v-model:viewи методамиfitView/relayout. Чипсы фильтров повторяют фигуры узлов, поэтому фильтр показывает, какую фигуру выбирает, а не только называет её. - Своё окно.
showDetailsHeadingвыключен,detailsTitle— функция, остальное дают#details-title,#details-tabsи#details. От пакета остаётся одна шапка. - Своя форма.
#details-editрисует контролы потребителя; пакет даёт черновик, сохранение и отмену — и больше ничего. - Свои меню и модалка.
showContextMenuвыключен, страница сама обрабатываетnode-context-menuи подтверждает удаление собственным диалогом. Пакет везёт и то и другое — здесь видно, что ни то, ни другое не обязательно. - И всё остальное тоже своё. Токены темы переопределены как обычные CSS-переменные на
.vam-root, три строки локали переименованы, а легенда — этоMapWindowв слоте#windows.
Правый клик по узлу открывает своё меню, кнопка правки — свою форму, а перетаскивание от точек по краям фигуры рисует кабель.
