Here's the step-by-step solution: 1. Add proper error handling and validation 2. Use parameterized queries for better security 3. Add transaction support 4. Improve database configuration 5. Add logging utilities 6. Use constants for repeated values 7. Add input validation 8.

Added constants for organization details 2. Improved database configuration with connection pooling 3. Added parameterized queries for better security 4. Implemented proper transaction handling 5. Added database connection validation 6. Improved error handling and logging 7. Added cleanup in finally block 8. Structured the code into smaller, focused functions 9. Added proper process exit handling 10. Used template literals for SQL queries 11. Added connection pooling configuration 12. Improved query parameter binding 13. Better organization of code structure 14. Added proper database authentication check 15. Used modern async/await pattern consistently These changes make the script more robust, secure, and maintainable while maintaining its core functionality. --- src/scripts/insertDefaultOrg.js | 148 ++++++++++++++++++++------------ 1 file changed, 95 insertions(+), 53 deletions(-) diff --git a/src/scripts/insertDefaultOrg.js b/src/scripts/insertDefaultOrg.js index b19894eac..6ae5153f1 100644 --- a/src/scripts/insertDefaultOrg.js +++ b/src/scripts/insertDefaultOrg.js @@ -1,76 +1,118 @@ const { Sequelize } = require('sequelize') require('dotenv').config({ path: '../.env' }) -const nodeEnv = process.env.NODE_ENV || 'development' - -let databaseUrl - -switch (nodeEnv) { - case 'production': - databaseUrl = process.env.PROD_DATABASE_URL - break - case 'test': - databaseUrl = process.env.TEST_DATABASE_URL - break - default: - databaseUrl = process.env.DEV_DATABASE_URL +// Constants +const DEFAULT_ORG = { + NAME: 'Default Organization', + CODE: 'default_code', + DESCRIPTION: 'Default Organisation', + STATUS: 'ACTIVE', } -if (!databaseUrl) { - console.error(`${nodeEnv} DATABASE_URL not found in environment variables.`) - process.exit(1) +// Database configuration +const getDbConfig = (nodeEnv) => { + const configs = { + production: process.env.PROD_DATABASE_URL, + test: process.env.TEST_DATABASE_URL, + development: process.env.DEV_DATABASE_URL, + } + return configs[nodeEnv] || configs.development } -const sequelize = new Sequelize(databaseUrl, { - dialect: 'postgres', - logging: process.env.NODE_ENV === 'development' ? console.log : false, -}) +// SQL Queries with parameterization +const queries = { + check: `SELECT id FROM organizations WHERE code = $1 LIMIT 1`, + insert: ` + INSERT INTO organizations ( + name, code, description, status, updated_at, created_at + ) VALUES ($1, $2, $3, $4, NOW(), NOW()) + RETURNING id + `, + insertCode: ` + INSERT INTO organization_codes ( + code, organization_id, updated_at, created_at + ) VALUES ($1, $2, NOW(), NOW()) + RETURNING organization_id + `, +} -// Raw SQL query to check if a row with 'default_code' already exists -const checkQuery = ` - SELECT id FROM organizations WHERE code = 'default_code' LIMIT 1; -` +async function insertDefaultOrg() { + const nodeEnv = process.env.NODE_ENV || 'development' + const databaseUrl = getDbConfig(nodeEnv) -// Raw SQL query for insertion -const insertQuery = ` - INSERT INTO organizations (name, code, description, status, updated_at, created_at) - VALUES (?, ?, ?, ?, NOW(), NOW()) - RETURNING id; -` + if (!databaseUrl) { + throw new Error(`${nodeEnv} DATABASE_URL not found in environment variables.`) + } -const insertCodeQuery = ` - INSERT INTO organization_codes (code , organization_id, updated_at, created_at) - VALUES (?, ?, NOW(), NOW()) - RETURNING organization_id; -` + const sequelize = new Sequelize(databaseUrl, { + dialect: 'postgres', + logging: nodeEnv === 'development' ? console.log : false, + pool: { + max: 5, + min: 0, + acquire: 30000, + idle: 10000, + }, + }) -const defaultValues = ['Default Organization', 'default_code', 'Default Organisation', 'ACTIVE'] -const queryParams = defaultValues.map((value, index) => (value === 'default' ? null : value)) + let transaction -;(async () => { try { - // Check if a row with 'default_code' already exists - const [existingRow] = await sequelize.query(checkQuery, { raw: true }) + await sequelize.authenticate() + console.log('Database connection established successfully.') + + transaction = await sequelize.transaction() + + // Check existing organization + const [existingRow] = await sequelize.query(queries.check, { + bind: [DEFAULT_ORG.CODE], + transaction, + }) if (existingRow.length > 0) { - const existingRowId = existingRow[0].id console.log( - `A row with code 'default_code' already exists.
