# Server
|
||||
|
||||
Лёгкий файловый backend без внешних зависимостей.
|
||||
|
||||
Быстрый старт
|
||||
- Сервер: `npm --prefix server start` (PORT=8080 по умолчанию). Если порт занят, сервер попробует 8081/8082/8083 автоматически.
|
||||
- Ручной выбор порта: `PORT=8088 npm --prefix server start`
|
||||
- Клиент отдельно (только статика, без API): `npx http-server frontend -p 9001` и открыть http://localhost:9001
|
||||
|
||||
Статика: раздаётся из `../frontend/dist`, при отсутствии сборки — из `../frontend`.
|
||||
|
||||
Хранилище: `server/data/projects/index.json` (список) + `server/data/projects/proj_<id>.json` (полный проект). При старте создаются при необходимости.
|
||||
|
||||
API:
|
||||
- `GET /api/projects[?type=project|template]` — укороченный список из `index.json`.
|
||||
- `GET /api/projects/:id` — полный JSON проекта.
|
||||
- `POST /api/projects` — создать проект, генерируется `id`, `createdAt`, `updatedAt`, сохраняется файл и обновляется индекс.
|
||||
|
||||
Поле `ownerId` пока всегда `null`, но оставлено для будущих пользователей/шаринга.
