# RelSpec
|
|
|
|
> Database Relations Specification Tool for Go
|
|
|
|
RelSpec is a comprehensive database relations management tool that reads, transforms, and writes database table specifications across multiple formats and ORMs.
|
|
|
|
## Overview
|
|
|
|
RelSpec provides bidirectional conversion and comparison between various database specification formats, allowing you to:
|
|
- Inspect live databases and extract their structure
|
|
- Convert between different ORM models (GORM, Bun , etc.)
|
|
- Transform legacy schema definitions (Clarion DCTX, XML, JSON, etc.)
|
|
- Generate standardized specification files (JSON, YAML, etc.)
|
|
|
|
|
|
|
|
## Features
|
|
|
|
### Readers (Input Formats)
|
|
|
|
RelSpec can read database schemas from multiple sources:
|
|
|
|
#### ORM Models
|
|
- [GORM](pkg/readers/gorm/README.md) - Go GORM model definitions
|
|
- [Bun](pkg/readers/bun/README.md) - Go Bun model definitions
|
|
- [Drizzle](pkg/readers/drizzle/README.md) - TypeScript Drizzle ORM schemas
|
|
- [Prisma](pkg/readers/prisma/README.md) - Prisma schema language
|
|
- [TypeORM](pkg/readers/typeorm/README.md) - TypeScript TypeORM entities
|
|
|
|
#### Database Inspection
|
|
- [PostgreSQL](pkg/readers/pgsql/README.md) - Direct PostgreSQL database introspection
|
|
|
|
#### Schema Formats
|
|
- [DBML](pkg/readers/dbml/README.md) - Database Markup Language (dbdiagram.io)
|
|
- [DCTX](pkg/readers/dctx/README.md) - Clarion database dictionary format
|
|
- [DrawDB](pkg/readers/drawdb/README.md) - DrawDB JSON format
|
|
- [JSON](pkg/readers/json/README.md) - RelSpec canonical JSON format
|
|
- [YAML](pkg/readers/yaml/README.md) - RelSpec canonical YAML format
|
|
|
|
### Writers (Output Formats)
|
|
|
|
RelSpec can write database schemas to multiple formats:
|
|
|
|
#### ORM Models
|
|
- [GORM](pkg/writers/gorm/README.md) - Generate GORM-compatible Go structs
|
|
- [Bun](pkg/writers/bun/README.md) - Generate Bun-compatible Go structs
|
|
- [Drizzle](pkg/writers/drizzle/README.md) - Generate Drizzle ORM TypeScript schemas
|
|
- [Prisma](pkg/writers/prisma/README.md) - Generate Prisma schema files
|
|
- [TypeORM](pkg/writers/typeorm/README.md) - Generate TypeORM TypeScript entities
|
|
|
|
#### Database DDL
|
|
- [PostgreSQL](pkg/writers/pgsql/README.md) - PostgreSQL DDL (CREATE TABLE, etc.)
|
|
|
|
#### Schema Formats
|
|
- [DBML](pkg/writers/dbml/README.md) - Database Markup Language
|
|
- [DCTX](pkg/writers/dctx/README.md) - Clarion database dictionary format
|
|
- [DrawDB](pkg/writers/drawdb/README.md) - DrawDB JSON format
|
|
- [JSON](pkg/writers/json/README.md) - RelSpec canonical JSON format
|
|
- [YAML](pkg/writers/yaml/README.md) - RelSpec canonical YAML format

|
relspec --input db --conn "postgres://..." --output gorm --out-file models.go
|
|
|
|
# Convert GORM models to Bun
|
|
relspec --input gorm --in-file existing.go --output bun --out-file bun_models.go
|
|
|
|
# Export database schema to JSON
|
|
relspec --input db --conn "mysql://..." --output json --out-file schema.json
|
|
|
|
# Convert Clarion DCTX to YAML
|
|
relspec --input dctx --in-file legacy.dctx --output yaml --out-file schema.yaml
