Simplified, 2 function, node pooling for PostgreSQL. Under the hood uses the pg.
Installation
yarn add tamed-pg
Usage
const tp = require('tamed-pg');
// Check Test section for DB configuration for the testing
const l_credentials = {
"user": "tamedpgusr",
"password": "easypassword",
"database": "tamedpgdb",
"port": 5432,
"host": "localhost"
};
const test = async () => {
let poolname = await tp.connect(l_credentials);
const l_result = await tp.runSQL(poolname, 'select 1 + 1 as solution', [], true);
const l_create_table = await tp.runSQL(poolname, 'create table if not exists tamedpg.test_table (id serial primary key, text varchar(40) not null, complete boolean)', [], true);
const l_insert = await tp.runSQL(poolname, 'insert into tamedpg.test_table(text, complete) values($1, $2) returning *', ['hello world', false], true);
const l_select = await tp.runSQL(poolname, 'select * from tamedpg.test_table where id = $1', [l_insert.rows[0].id], true);
const l_update = await tp.runSQL(poolname, 'update TamedPG.test_table SET text = $1, complete = $2 WHERE id = $3', ['hello world 2', true, l_insert.rows[0].id], true);
const l_select2 = await tp.runSQL(poolname, 'select * from tamedpg.test_table where id = $1', [l_insert.rows[0].id], true);
const l_delete = await tp.runSQL(poolname, 'delete from tamedpg.test_table where id = $1', [l_insert.rows[0].id], true);
const l_select3 = await tp.runSQL(poolname, 'select * from tamedpg.test_table where id = $1', [l_insert.rows[0].id], true);
const l_drop_table = await tp.runSQL(poolname, 'drop table TamedPG.test_table', [], true);
let releaseResult = await tp.end(poolname);
}

The jest tests assume a DB is prepared already with following commands.
- Generate a DB for the test.
sudo -u postgres createdb tamedpgdb- Generate the user with small letters:
sudo -u postgres psql << EOF
create user tamedpgusr encrypted password 'easypassword';
grant all on database "tamedpgdb" to tamedpgusr;
\c tamedpgdb;
create schema tamedpg authorization tamedpgusr;
EOF- Add following line to
/etc/postgresql/[VERSION]/main/pg_hba.confin the local area before the peer row in order to take precedence.
local all tamedpgusr scram-sha-256
- Restart the service.
sudo service postgresql restart- Test
yarn test- After tests are finished clean the database
sudo -u postgres psql << EOF
\c tamedpgdb;
drop schema tamedpg;
revoke all on database "tamedpgdb" from tamedpgusr;
drop user tamedpgusr;
