jnext-library-ts
An authentication library for Node.js simplifies the implementation of authentication-related functionalities in your Express applications. It provides tools for managing Sequelize models, creating Express routes, initializing email configurations, and Swagger documentation setup.
Installation
npm install jnext-library-ts
Usage
1. Setup server connection in your project
import dotenv from 'dotenv';
dotenv.config();
import express, { Express } from 'express';
import { Sequelize } from 'sequelize';
import * as myLib from 'jnext-library-ts';
// Create an Express application
const app: Express = express();
const sequelize = new Sequelize('dbName', 'root', '', {
dialect: 'mysql',
host: '127.0.0.1',
logging: false
});
// Start the server on port 7000
app.listen(7000, () => {
console.log(`Server is started on port:`, 7000);
});
2. Create Sequelize Models
Use the getModels
function to retrieve predefined Sequelize models for users, user_meta, and user_roles. The user_roles model is automatically populated with data for the 'user' and 'admin' roles. Additionally, you can dynamically add fields to the user model using createModel()
.
import { Sequelize } from 'sequelize';
import * as myLib from 'jnext-library-ts';
const sequelize = new Sequelize('dbName', 'root', '', {
dialect: 'mysql',
host: '127.0.0.1',
logging: false
});
myLib.getModels();
myLib.createModel('customUserModel', sequelize, {
// Define additional fields here
filedName: dataType // Datatype should be string. Ex. 'STRING' , 'INTEGER'
});
3. Create Express Routes
Use the createRoutes
function to fetch API routes from the library for use in your Express application.
import express, { Express } from 'express';
import * as myLib from 'jnext-library-ts';
const router = myLib.createRoutes({ validator: false });
const app: Express = express();
app.use('/', router);
4. Set Environment variables in .env files
PORT: 8000
#JWT comfiguration details
JWT_SECRET: jwtSecretkey
JWT_EXPIRATION_TIME: Expiration time of jwt. Example - 1h
#APIs prefix route to access swagger
API_BASE_PREFIX: /
#To manage delete APIs functionality. Hard delete or soft delete
HARD_DELETE: false
#To add/ manage custome templete for email Templetes in request data
CUSTOM_TEMPLATE: true
#To manage send mail using SMTP or sendmail()
SMTP=true
Example
import express, { Express } from 'express';
import Sequelize from 'sequelize';
import * as myLib from 'jnext-library-ts';
const router = myLib.createRoutes({ validator: false });
const sequelize = new Sequelize.Sequelize('authapis', 'root', '', {
dialect: 'mysql',
host: '127.0.0.1',
logging: false
});
myLib.getModels();
myLib.createModel('customUserModel', sequelize, {
// Define additional fields here
});
const app: Express = express();
app.use('/', router);
app.listen(8000, () => {
console.log(`Server is started on`, 8000);
});
