+Usage
+You can use this library to perform initialization of a PostgreSQL database server (version 11 and later). For example, creating databases, schemas, roles, users, and grants.
Here is an example to provision several database objects.
import { Login, Role, Catalog } from "@libreworks/db-provision-pgsql";
const username = "example_user";
const password = "🙈";
const owner = new Login(username, password);
const admin = new Role("admin");
const readers = new Role("readers");
const grants = [admin.assignTo(owner)];
const catalog = new Catalog("my_database");
const schema = catalog.createSchema(username, owner);
grants.push(
catalog.grant(owner, "CONNECT", "TEMP"),
catalog.grant(readers, "CONNECT", "TEMP"),
schema.grant(readers, "USAGE"),
schema.allTables().grant(readers, "SELECT"),
schema.allSequences().grant(readers, "SELECT"),
schema.setDefaultTablePrivileges(readers, "SELECT").forCreator(owner),
schema.setDefaultSequencePrivileges(readers, "SELECT").forCreator(owner)
);
// Display the SQL
const statements = [
owner,
admin,
readers,
catalog,
schema,
...grants,
].map((v) => v.toSql());
console.log(statements.join(";\n") + ";\n");
