Convert Postgres schemas into TypeScript interfaces
MySQL implementation: http://github.com/nettofarah/mysql-schema-ts
# to infer an entire schema
$ npx postgres-schema-ts postgresql://postgres@localhost:5433/db?currentSchema=public
# to infer a specific table
$ npx postgres-schema-ts postgresql://postgres@localhost:5433/db?currentSchema=public table_name
tip: You can pipe the output of postgres-schema-ts into a file with npx postgres-schema-ts <args> > schema.ts
For the following SQL schema:
CREATE TABLE account (
username VARCHAR (50) UNIQUE NOT NULL,
password VARCHAR (50) NOT NULL,
email VARCHAR (355) UNIQUE NOT NULL,
created_on TIMESTAMP NOT NULL,
last_login TIMESTAMP
)
run:
$ npx postgres-schema-ts postgresql://postgres@localhost:5433/db?currentSchema=public
export interface account {
username: string
password: string
email: string
created_on: Date
last_login: Date | null
}
import { inferSchema, inferTable } from 'postgres-schema-ts'
await inferSchema(connectionString)
await inferTable(connectionString, tableName)
postgres-schema-ts is inpired by the awesome schemats library. But takes a simpler, more blunt, and configuration free approach:
- Simpler defaults
- Postgres support only
- Inline enums
- No support for namespaces
