node-sql-reader

This library can parse pure sql file or sql string into queries array.
The main use case that made me create this library was the inability of TypeOrm to run sql file. I needed to run sql file with test data each time when I restart a server to get the same starting test data. So TypeOrm can run the single query, but it can't run a file with sql. So this lib can help you to parse a file and get separate queries from it.

Install

npm install node-sql-reader

Usage

test_data.sql

INSERT INTO users (email, password, name) VALUES ('[email protected]', 'hashed_password1', 'dummy1');
INSERT INTO users (email, password, name) VALUES ('[email protected]', 'hashed_password2', 'dummy2');
INSERT INTO users (email, password, name) VALUES ('[email protected]', 'hashed_password3', 'dummy3');

TestDataInitializer.ts

import { SqlReader } from 'node-sql-reader'
import * as path from 'path';

export class TestDataInitializer {
    initTestData() {
        let queries = SqlReader.readSqlFile(path.join(__dirname, "../database/test_data.sql"))
        for (let query of queries) {
            // replace it with your query runner
            SomeQuerryRunner.runQuerry(query)
        }
    }
}

/*
queries array:
[
   "INSERT INTO users (email, password, name) VALUES ('[email protected]', 'hashed_password1', 'dummy1')",
   "INSERT INTO users (email, password, name) VALUES ('[email protected]', 'hashed_password2', 'dummy2')",
   "INSERT INTO users (email, password, name) VALUES ('[email protected]', 'hashed_password3', 'dummy3')",
]
