Get start
Create connection
import {Connection, Table} from "postgresjs";
const config {
host: "host",
port: "port",
user: "user",
password: "password",
database: "database"
}
const connection = new Connection(config);
For better work, I advise you to create 1 type with column names and 1 interface with column values.
interface iUser{
id?: string; // {?} - if the column is autoincrement
username: string;
email: string;
password: string;
}
type tUser = "id" | "username" | "email" | "password";
Now let's connect to the table
// For each table, create an instance of that table's class
const usersTable = new Table<iUser, tUser>(connection, "users");
const carsTable = new Table<iCars, tCar>(connection, "cars");
Select all rows or a specific row
// Select all
userTable.selectAll().then(data => console.log(data));
// sort
const sort = {
by: "id",
type: "ASC"
}
userTable.selectAll(sort).then(data => console.log(data));
// Select row
userTable.selectRow("id", 5).then(data => console.log(data));
Delete all rows or a specific row
// Delete all
userTable.deleteAll();
// Delete row
userTable.delete("id", 5);
Update row
const columns = ["username", "email"];
const values = ["alex", "[email protected]"];
conste updateCol = {
column: "id",
value: 5
}
userTable.update(columns, values, updateCol);
userTable.update("username", "alex", updateCol);
Drop table
ATTENTION!!! THIS METHOD DELEtypescript THE TABLE, NOT THE ROWS!!!
userTable.drop();
Create table
const tableData = {
tableName: "new table name",
owner: "username",
columns: [
{
name: "id",
type: "bigint",
isAutoincrement: true,
isPrimarry: true,
},
{
name: "userData",
type: "text",
isNull: true,
isArray: true
},
...
]
}
*
myTable.createTable(tableData);
Custom querry
myTable.custom("SELECT * FROM users");
myTable.custom("INSERT INTO users (username, email) VALUES $1, $2", ["username", "useremail"]);
