Opinionated wrapper around mysql2.
Install both @rich_harris/sql and mysql2 (which is a peer dependency, not included):
npm i @rich_harris/sql mysql2import { connect } from '@rich_harris/sql';
async function main() {
const db = await connect({
connectionLimit: 100, // number of simultaneous pooled connections
host: 'localhost',
user: 'root',
database: 'my-database'
});
await db`
CREATE TABLE IF NOT EXISTS people (
id MEDIUMINT NOT NULL AUTO_INCREMENT,
first_name VARCHAR(30),
last_name VARCHAR(30),
email VARCHAR(80),
dob DATE,
PRIMARY KEY (id)
);
`;
// fake data via mockaroo.com
const person = {
first_name: 'Llewellyn',
last_name: 'Satcher',
email: 'lsatcher1@nhs.uk',
dob: new Date(1982, 7, 15)
};
await db`
INSERT INTO people (first_name, last_name, email, dob) VALUES(
${person.first_name},
${person.last_name},
${person.email},
${person.dob}
);
`;
const { rows } = await db`
SELECT first_name, last_name FROM people WHERE email=${person.email}
`;
console.log(rows);
await db.close();
}Any ${values} are automatically escaped etc. Every time you run a query, it will get or create a pooled connection, and release it once the query is complete.
As well as executing arbitrary queries, there is a convenience method for inserting data:
const table = await db.table('people');
const people = [{
first_name: "Rodolphe",
last_name: "McAlinden",
email: "rmcalinden4@printfriendly.com",
dob: "7/27/2017"
}, {
first_name: "Laural",
last_name: "Lebell",
email: "llebell5@marketwatch.com",
dob: "9/4/2017"
}, {
first_name: "Binny",
last_name: "MacFarlane",
email: "bmacfarlane6@cnet.com",
dob: "1/3/2018"
}, {
first_name: "Adams",
last_name: "Keeble",
email: "akeeble7@arstechnica.com",
dob: "2/5/2018"
}, {
first_name: "Dill",
last_name: "Everest",
email: "deverest8@t-online.de",
dob: "7/25/2017"
}]
await table.insert(people[0]); // insert a single row
await table.insert(people); // insert many rows
