Express Sequelize AutoCRUD

Express Sequelize AutoCRUD is a powerful and developer-friendly TypeScript library designed to simplify the creation of CRUD (Create, Read, Update, Delete) routes for your Sequelize models in an Express.js application. If you're building RESTful APIs with Express and using Sequelize as your ORM, this library will save you significant development time and effort.


Features

- Automatic CRUD Operations: Easily generate CRUD endpoints for your Sequelize models with just a few lines of code.
- Customizable Routes: Configure routes according to your project's specific requirements.
- Validation and Error Handling: Built-in request validation and error handling for seamless API development.
- Middleware Support: Integrate custom middleware functions with generated routes to extend functionality.
- Transaction Support: Create, Update and Delete routes runs inside sequelize transaction to handle pre/post hooks and rollback automatically in case something failed in the process.
- Secure and Efficient: Utilizes Sequelize's robust security features and optimized database queries.

Installation

Using npm:

``bash
npm i express-sequelize-autocrud
`

Using yarn:

`bash
yarn add express-sequelize-autocrud
`

Using pnpm:

`bash
pnpm i express-sequelize-autocrud
`

Usage

Using Express Sequelize AutoCRUD is straightforward:

`typescript
import express from 'express';
import {Sequelize} from 'sequelize';
import sequelizeCrud from 'express-sequelize-autocrud';

const app = express();
const sequelize = new Sequelize('your_db', 'your_user', 'your_password', {
host: 'localhost',
dialect: 'mysql',
});

// Define your Sequelize models here

// Generate routes using express-sequelize-autocrud
app.use(
'/api',
sequelizeCrud(sequelize, {
'/users': {
model: sequelize.model('users'),
operations: {
getList: {
filterableFields: ['id', 'gender'],
attributes: ['id', 'fullName', 'gender'],
limit: 100,
},
getOne: {
attributes: req =>
req.user.role === 'admin'
? ['id', 'fullName', 'secretStuf']
: ['id', 'fullName'],
},
create: {
creatableFields: {exclude: ['id']},
},
update: {
updatableFields: {exclude: ['id']},
},
delete: {
middleware: (req, res, next) => {
if (req.user.role === 'admin') {
next();
} else {
res.sendStatus(403);
}
},
},
},
},
})
);

// Start your Express server
const port = process.env.PORT || 3000;
app.listen(port, () => {
console.log(Server is running on port ${port});
});
`

CRUD Routes

| Operation | URL | Sequelize Operation | Comment |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| getList | Clean:
_GET_ /

With pagination:
_GET_ /?_start=30&_end=60

With sort & filters:
_GET_ /?_sort=createdAt&_order=DESC&gender=female | findAll()
or
findAndCountAll() | - Enable pagination with pagination: true in the config.
- Pagination automatically adds Content-Range header.
- Can control which fields can be filterable using filterableFields in the config.
- Can control which fields can be sortable using sortableFieldsFields in the config. |
| getOne | _GET_ //:resourceId | findByPk()
or
findOne() | - Can set custom key (not primary key) using byField in the config. |
| create | _POST_ / | create() | - Can control which fields can be added to body request using creatableFields in the config. |
| bulkCreate | _POST_ //bulk | bulkCreate() | - Can control which fields can be added to body request using creatableFields in the config.
- Can custom the url path with path in the config (default: /bulk) |
| update | _PUT_ //:resourceId | update() | - Can control which fields can be added to body request using updatableFields in the config.
- Can set custom key (not primary key) using byField in the config. |
| delete | _DELETE_ //:resourceId | destroy()` |- Can set custom key (not primary key) using byField in the config. |
