Volan Language Server
Prisma-style language tooling for Volan schema files in VS Code.
Volan brings schema-first ORM development to the JVM. This extension gives *.volan files a real language server powered by Volan's parser, semantic analyzer and formatter.
Features
- IntelliSense for models, enums, fields, types and attributes;
- context-aware completion for
@default, enum values, relations and native database types;
- type-aware default values:
now(), uuid(), autoincrement(), literals and list defaults;
- syntax and semantic diagnostics with actionable error messages;
- hover documentation for declarations, types and attributes;
- go to definition and document symbols;
- semantic highlighting;
- document and range formatting;
- a bundled local language server — no network service is required at runtime.
Quick start
- Install the extension from the Marketplace.
- Open a
schema.volan file.
- Start typing a Volan schema and use
Ctrl+Space for completion.
Example:
enum Role {
USER
ADMIN
}
model User {
id Int @id @default(autoincrement())
balance Double @default(0.5)
role Role @default(USER)
createdAt DateTime @default(now())
}
Requirements
- VS Code 1.90 or newer;
- JRE 17 or newer for the bundled language server.

Русская версия
Расширение добавляет полноценную поддержку файлов *.volan в VS Code: подсказки, диагностику, hover, переход к определениям, semantic highlighting и форматирование. Автодополнение учитывает тип поля и контекст — в том числе enum-значения и аргументы @default(...).
