postez v2.0.1

Usage

Define a types schema as

typesSchema = {
 'string': [ 'bpchar', 'char', 'varchar', 'text', 'citext', 'uuid' ],
 'number': ['int2', 'int4', 'int8', 'float4', 'float8', 'numeric' ],
 'boolean': ['bool', 'boolean'],
 'Date': ['date', 'timestamp', 'timestamptz'],
 'Array<number>': ['_int2', '_int4', '_int8', '_float4', '_float8', '_numeric', '_money'],
 'Array<boolean>': ['_bool', '_boolean'],
 'Array<string>': ['_varchar', '_text', '_citext', '_uuid', '_bytea'],
 'Object': ['json', 'jsonb'],
 'Array<Object>': ['_json', '_jsonb'],
 'Array<Date>': ['_timestamptz'],
 'CustomTypes': [
  {
   name: 'point',
   type: 'Coordinates',
   definition: 'export interface Coordinates { x: number; y: number; }',
  },
 ],
}

then just pass it as an argument with a database connection and output path.

postez(db, path, typesSchema)
  .then(() => console.log("Done."))
  .catch((e) => console.error(e));

You can also specify the name of table schema you want to generate types.ts.

postez(db, path, typesSchema, 'schema_name')
  .then(() => console.log("Done."))
  .catch((e) => console.error(e));

Otherwise you can use a default types schema (table schema name is 'public' by default if not specified) and pg-promise as simple as:

import pg from 'postez/lib/db'
import { postez } from "postez";

const configuration = {
	user: 'username',
	password: 'password',
	host: 'host',
	port: 'port',
	database: 'database'
}

const db = pg.db(configuration)
const path = process.cwd().replace('./dist', './output');

postez(db, path)
  .then(() => console.log("Done."))
  .catch((e) => console.error(e));

on successfull run it will prompt out the following:

Succesfully generated files in: <path>/output/types.ts
